“The Gaslighting of Hannah Pettey”: 48 Hours Reports September 5 2026

CBS’s 48 Hours returns to one of its most disturbing recent attempted-murder cases with an encore of “The Gaslighting of Hannah Pettey” on Saturday, September 5, 2026, at 9/8c. Correspondent Anne-Marie Green examines how a young Alabama mother’s unexplained medical decline became a poisoning investigation, and how police built a case against the person prosecutors said had been trying to kill her for months: her husband, chiropractor Brian Thomas Mann.

Hannah Pettey had been sick for months before doctors discovered what was happening. She suffered severe abdominal and back pain, nausea, vomiting, weakness and weight loss. By January 2022, she could barely walk. After her mother took her to the University of Alabama at Birmingham hospital, Hannah suffered a seizure and came close to death. Doctors eventually discovered an extraordinary concentration of lead throughout her body.

The discovery changed everything. Doctors concluded that Hannah had not suffered an ordinary environmental exposure. Investigators came to believe she had been given lead over an extended period. Suspicion turned toward the supplements her husband had been providing, and a contractor would later reveal that Mann had access to sheets of soft lead at his chiropractic office.

The case was built without an eyewitness to the poisoning and without police recovering a lead-filled capsule. Prosecutors instead assembled medical evidence, Hannah’s testimony, evidence of Mann’s access to lead and a financial motive involving life insurance policies worth millions of dollars.

In June 2025, a Morgan County jury convicted Mann of attempted murder. Two months later, he received a life sentence. Mann challenged his conviction, but in June 2026 the Alabama Court of Criminal Appeals affirmed both his conviction and sentence. He is now serving his sentence at Limestone Correctional Facility in Alabama.

• Who Is Hannah Pettey & Where Is She Now? 2026 Update & Profile
• Who Is Brian Thomas Mann & Where Is He Now? 2026 Update & Profile

Hannah Pettey Met Brian Mann When She Was 18

Hannah Pettey was 18 when she met Brian Mann in 2017. She had graduated from high school and moved into her own apartment. Mann was 29, worked as a chiropractor and operated his own practice. Their relationship developed within months.

Mann told friend Walker Snyder that Hannah was “the one” soon after meeting her. Hannah became pregnant, and Mann proposed after they had been together for only a few months. The couple married in May 2018. They would have two children, a son named Lincoln and a daughter named Gracie.

There were concerns before the wedding. Hannah later told 48 Hours that Mann could be controlling, and she experienced doubts on her wedding day. Her mother, Nicole Pettey, told her that she could walk away if her hesitation represented something more serious than wedding nerves.

Hannah went through with the marriage. She later described Mann as a husband who could be good to her but said their relationship also involved physical fights. She acknowledged that she had a tendency to explain away some of the problems in the marriage.

Hannah and Her Mother Said There Were Warning Signs in the Marriage

One incident occurred when Hannah was nine months pregnant with her son. After she began bleeding, she went to a hospital. According to Hannah, Mann arrived and became angry with her, blaming her for walking in hot weather and accusing her of being irresponsible.

Hannah’s friend Alyson Holmes said nurses noticed Mann’s behaviour and gave Hannah a code word she could use if she wanted staff members to intervene. Hannah did not use it.

The relationship between Mann and Hannah’s mother was also hostile. Nicole said Mann avoided her throughout the marriage. She said she could visit Hannah only when Mann was at work and needed to leave before he returned.

Mann presented a different account. He portrayed Nicole as a destructive presence in Hannah’s life and said Hannah had complained that her mother criticised her. He later suggested Nicole was responsible for turning authorities against him when Hannah’s poisoning was discovered.

The conflict between Mann and Nicole would become important once investigators began asking who could have poisoned Hannah.

Hannah’s Health Began to Collapse in 2021

During 2021, Hannah began experiencing unexplained medical problems. The symptoms grew worse over a period of about six months.

She suffered abdominal and back pain, nausea, vomiting and increasing weakness. She lost a substantial amount of weight. By January 2022, Hannah said she was spending days in bed and had become so weak that she used an office chair to move around her house.

She was still trying to care for Lincoln, who was three, and Gracie, who had turned two. Her condition became so severe that she could not attend her daughter’s birthday party.

The cause remained unknown.

Mann was a chiropractor, but he said Hannah’s condition was outside his area of expertise. Hannah recalled that as her illness became worse, her husband became sweeter toward her.

What she did not know was that the substance destroying her health had been entering her body over time.

A Phone Call Convinced Nicole That Her Daughter Needed Help

On January 18, 2022, Nicole spoke to Hannah and became concerned by the sound of her voice. She continued calling and texting her daughter.

When Hannah called back, she could barely speak.

She asked her mother to take her to the hospital.

Nicole drove to Hannah’s home and took her to UAB Hospital in Birmingham. Doctors recognised that Hannah was ill, but her vital signs initially created uncertainty about whether she would be admitted.

Then Hannah suffered a major seizure.

The seizure removed any doubt about the seriousness of her condition. Nicole recalled seeing how much weight her daughter had lost when Hannah’s hospital gown came off during the medical emergency.

Doctors told Nicole that Hannah was starving to death and might have had only hours to live.

Hannah Suffered a Seizure and Lost Consciousness

The seizure left Hannah unconscious. Nicole attempted to contact Mann and sent him a message explaining that his wife had suffered a seizure and had not regained consciousness.

Nicole said she received no response from him.

Mann learned about Hannah’s condition through his mother and later travelled to the hospital. COVID restrictions meant only one visitor could be with Hannah at a time, creating another point of conflict between Mann and Nicole.

Hannah remained unconscious for close to 48 hours. Nicole recalled bending over her daughter, kissing her head and telling her that she loved her. Hannah opened her eyes and responded.

Her return to consciousness did not mean the medical crisis was over.

Hannah developed severe swelling and excess fluid around her brain. Doctors placed her into a medically induced coma and paralysed her while treating the condition. Movement itself presented a danger.

The young mother who had entered the hospital with an unexplained illness was now fighting for her life.

Doctors Discovered Hannah’s Body Was Filled With Lead

Eight days after Hannah entered the hospital, her neurologist gave Nicole the diagnosis that transformed the case.

Hannah had an enormous amount of lead inside her body.

Medical imaging produced startling evidence. Her digestive tract contained so much lead that it was visible on X-rays. Nicole recalled being told that Hannah’s colon was packed with the metal. Lead had also entered her bones and bloodstream.

The quantity presented a medical emergency. Lead is toxic to the nervous system and can damage the brain, kidneys, digestive system and other organs. In Hannah’s case, doctors were dealing with an exposure severe enough to threaten her life.

The amount also raised a second question.

How had it entered her body?

Doctors did not believe Hannah’s condition could be explained by ordinary environmental exposure. The pattern indicated ingestion, and the quantity suggested repeated exposure.

Someone might have been poisoning her.

The Hospital Treated Hannah’s Body as Evidence of a Crime

Once doctors suspected deliberate poisoning, Hannah ceased to be only a medical patient. She was also the possible victim of attempted murder.

The hospital reported the case to Alabama’s Department of Human Resources. Access to Hannah was restricted. Nicole and Mann were both told to leave because investigators could not initially know which person, if either, was responsible.

Nicole remembered being told that someone was trying to kill her daughter.

The question was who.

Both Hannah’s mother and husband had access to her at different times. Both therefore needed to be considered until investigators could establish the circumstances surrounding the poisoning.

Mann said his first reaction was to suspect that Nicole had engineered the accusations against him. He continued to portray his mother-in-law as the source of problems in his marriage.

Investigators needed evidence rather than family accusations.

The Supplements Beside Hannah’s Bed Became a Key Clue

Doctors wanted to know everything Hannah had eaten, drunk or swallowed during the months before she entered the hospital.

Nicole then remembered something Hannah had told her.

Mann had been providing Hannah with supplements.

According to Hannah’s later account, her husband placed capsules on her nightstand for her to take at night. Given Mann’s profession, the use of supplements had not seemed suspicious to her family.

Now it carried a different significance.

If Hannah had been ingesting lead over a period of months, capsules offered a possible method of administration. A capsule could be opened, its original contents removed, a toxic substance placed inside and the capsule closed again.

Investigators began considering whether Hannah had swallowed the substance while believing she was taking vitamins.

Police Began Investigating Brian Mann

The Department of Human Resources contacted Lt. Alan McDearmond of the Hartselle Police Department. McDearmond was told that doctors suspected Mann had been giving his wife capsules containing lead.

McDearmond did not believe the medical suspicion alone justified an arrest.

He needed to determine whether evidence supported it.

Mann initially cooperated. When police asked for permission to search the family home, he agreed. Investigators examined food, medications, cosmetics and other items that might have explained Hannah’s exposure.

Mann provided supplements and a laxative that he said Hannah had used.

Police found no contaminated supplement.

They found no lead-filled capsule.

They found no evidence at the house of someone grinding, scraping or processing lead.

Tests of items recovered from the home came back negative.

Those results created a significant problem for investigators. They knew Hannah had been poisoned, but they did not have the substance that had been used to poison her.

Police Initially Had a Victim but No Murder Weapon

The absence of contaminated capsules became one of the strongest points later raised by Mann’s defense.

No witness had seen Mann put lead into a capsule.

Police had not recovered a capsule containing lead.

They had not found lead residue in the house.

There was no video of Mann preparing poison and no confession.

McDearmond acknowledged that the investigation initially lacked much physical evidence.

Investigators also needed to consider Nicole. Mann was telling them that his mother-in-law should be suspected, and the hostility between the two sides of the family meant police could not dismiss that possibility without examination.

On February 1, McDearmond cleared Nicole. He said her conduct and the information investigators developed were consistent with a mother trying to care for a gravely ill daughter. He also acknowledged that behaviour itself was not proof of a crime.

Nicole was permitted to return to Hannah’s hospital room.

Doctors Feared Hannah Might Never Become a Witness

Hannah’s medical condition created another problem for police.

Investigators did not know whether she would survive, much less whether she would recover enough cognitive function to explain what had happened during the preceding months.

When McDearmond first tried to interview her, Hannah’s mental state remained impaired. She could answer coherently at some moments and become confused at others. She reported hallucinations, including seeing people coming through walls.

Medical staff warned investigators that Hannah might never recover enough brain function to become a useful witness.

That possibility meant detectives needed to construct the case without relying on the person who knew the most about her daily life.

Hannah defied those expectations.

Her condition began improving. Nurses encouraged her by reminding her of her children, and she became determined to return to them.

Hannah Learned That Police Suspected Her Husband

As Hannah recovered, her neurologist told her why doctors and investigators believed Mann could be responsible.

The information devastated her.

The person she had viewed as her caregiver during her illness was now suspected of causing it.

After close to two months in the hospital, Hannah was discharged on March 3, 2022. She went to live with Nicole, reunited with her children and filed for divorce.

Her physical survival did not resolve her feelings toward Mann.

Within days, Hannah began questioning whether police could be right.

Hannah Went Back to See Brian Mann

About one week after leaving the hospital, Hannah returned to the home she had shared with Mann and met him face to face.

She wanted an explanation.

Hannah later said she expected Mann to reject the accusation in terms that would convince her it was impossible. Instead, she did not receive the response she wanted.

Despite that, she contacted her divorce attorney and said she no longer wanted to proceed. She began believing that another explanation for the poisoning had to exist.

She also asked McDearmond to end the criminal investigation.

The decision alarmed her family and friends. Nicole said Hannah’s family doctor feared Mann could kill her if she returned to him.

McDearmond faced a practical problem. Without Hannah’s cooperation, proving the case would become much harder.

A Police Form Changed Hannah’s Decision

McDearmond told Hannah that he would close the case if that was what she wanted.

But he asked her to sign a document.

He explained that the form would establish that police had stopped investigating at her request. If Mann later killed her and her family accused police of failing to protect her, investigators could show that Hannah had asked them to stop.

The possibility forced Hannah to confront what she was risking.

She refused to sign.

Instead, she told McDearmond to continue investigating.

Hannah resumed cooperation with police and continued pursuing the divorce.

Then she told investigators about something that gave the case a possible motive.

Life insurance.

Investigators Discovered Millions of Dollars in Life Insurance

Hannah told police that Mann had begun taking out life insurance on her while they were still dating.

Investigators examined the policies.

Evidence later presented around the case showed that Mann had obtained multiple policies on Hannah’s life and was positioned to receive substantial sums if she died. Additional insurance applications were made while Hannah was hospitalized.

According to 48 Hours, if the additional policies had been approved, the potential payout could have exceeded $5 million.

Prosecutors viewed the insurance as the financial motive behind the poisoning.

The timing carried particular weight. Hannah was in the hospital fighting for her life while efforts were being made to obtain additional coverage.

Another allegation added to the prosecution’s interpretation of the insurance evidence. Hannah said Mann had made her wear ankle weights during medical check-ups so that her dramatic weight loss would not be apparent on the scale and raise questions that could affect insurance coverage.

Prosecutors Developed a Theory of Slow Murder for Money

Morgan County prosecutor Garrick Vickery concluded that Hannah had been intentionally poisoned and that Mann was the person with the opportunity to administer the lead.

The state’s theory was that Mann had chosen a method designed to resemble illness rather than violence.

Instead of administering one fatal dose, prosecutors believed he supplied Hannah with lead over a period of months.

Her deterioration could then appear to be an unexplained medical condition.

The supplements provided a delivery system. The life insurance provided the alleged motive. Mann’s access to Hannah provided opportunity.

What prosecutors still lacked was a source of lead that they could connect to him.

That would come from an unexpected witness.

Brian Mann Was Charged With Attempted Murder

A Morgan County grand jury considered the evidence and returned an indictment.

Mann was arrested in September 2022 and charged with attempted murder.

He pleaded not guilty.

Mann was released on a $500,000 bond under strict conditions. He wore an ankle monitor and was required to report to jail on weekends.

He maintained his innocence and continued blaming Nicole for the accusations.

Even after the indictment, however, investigators had an evidentiary weakness.

They had not established where Mann would have obtained the lead.

Then contractor Danny Hill saw news coverage of Mann’s arrest.

He contacted police.

A Contractor Revealed That Mann Had Access to Sheets of Lead

Hill had performed work at Mann’s chiropractic office.

The job involved constructing an X-ray room.

X-ray rooms require shielding to protect people outside the room from radiation. Hill had installed rolls of soft sheet lead inside the walls before covering them with drywall.

The material was important because it was not a hard block of metal.

It could be scraped.

Hill demonstrated how easily small pieces could be shaved from the material and placed inside an empty capsule.

He also remembered something else.

There had been lead left over after the construction work.

Hill said he asked Mann whether he should dispose of it.

Mann told him he would take care of it.

Police Searched Mann’s Chiropractic Office

Hill’s information gave investigators a direct connection between their suspect and a supply of lead.

Police obtained a search warrant for Mann’s chiropractic office.

Investigators removed a section of the X-ray room wall and recovered the thin lead sheeting.

The discovery did not prove that the lead in Hannah’s body had been scraped from that particular sheet. Nor did investigators recover a poisoned capsule from the office.

What it established was access.

The prosecution could now show jurors that Mann had access to a material capable of producing the type of lead particles prosecutors believed had been placed into capsules.

For Vickery, the contractor’s call filled a major gap in the circumstantial case.

Police now had a plausible source for the poison.

Hannah’s Body Had Become the Crime Scene

The physical evidence of the attack was inside Hannah herself.

Her X-rays showed the lead in her digestive system. Her blood work documented the poisoning. Her medical history recorded months of decline.

Prosecutors would later use those records to reconstruct an attempted murder that no one had witnessed.

Hannah had been losing weight, suffering pain and becoming weaker while continuing to take capsules Mann supplied.

She remembered one night when she was in severe pain and felt too nauseated to take anything.

According to Hannah, Mann told her that he had placed her vitamins on the nightstand.

She told him she could not take them.

Hannah said Mann became upset and insisted that she needed to swallow them.

That memory became one of the prosecution’s most important pieces of testimony about the alleged delivery method.

The Poisoning Left Hannah With Permanent Consequences

Hannah survived, but survival did not mean returning to the condition she had been in before the poisoning.

The lead caused extensive damage.

Among the consequences was one that Hannah did not reveal publicly until the trial: doctors told her she could no longer have children.

She was 22.

The poisoning therefore left consequences that continued after the lead had been removed from her digestive system and after she had left the hospital.

It also meant that the jury would hear not only about an attempted killing but about the permanent harm inflicted during the months in which the poisoning took place.

Brian Mann Went on Trial in June 2025

Almost three years after Mann’s arrest, his attempted-murder trial began in Morgan County, Alabama, in June 2025.

Mann was 36 and faced the possibility of spending much of the rest of his life in prison.

Cameras were not permitted inside the courtroom.

Prosecutors Garrick Vickery and Kelly Cimino presented a case built around circumstantial evidence. Their argument was that the pieces had to be considered together rather than in isolation.

Hannah had suffered deliberate lead poisoning.

Mann had access to her.

He supplied capsules she swallowed.

He had access to soft lead at his office.

He had substantial life insurance interests connected to her death.

The state argued those facts formed a single explanation.

Mann had tried to kill his wife.

Hannah Pettey Became the State’s First Witness

The woman doctors once feared might never regain enough cognitive function to speak for herself walked into court as the prosecution’s first witness.

Hannah described her marriage, illness and the supplements Mann supplied.

She told jurors about Mann putting vitamins on her nightstand and insisting that she take them even when she was in severe pain and felt unable to swallow them.

She also described the consequences of the poisoning.

Medical records, X-rays and scans allowed prosecutors to present the progression of Hannah’s illness.

Her body provided proof that the poisoning itself had occurred.

The disputed question was the identity of the poisoner.

The Defense Said There Was No Direct Proof Mann Poisoned Hannah

Defense attorney Chad Morgan attacked the central weakness in the state’s case.

Nobody saw Mann put lead into a capsule.

Police never recovered a lead-filled capsule.

The original search of the Mann home found no lead contamination.

No physical evidence showed Mann scraping the sheets inside his office and putting the shavings into supplements.

The defense argued that prosecutors were asking jurors to substitute inference for proof.

Morgan also directed suspicion toward Nicole.

The defense suggested Hannah’s mother could have delivered lead through milkshakes she brought to her daughter.

Hannah disputed the premise, saying she did not recall her mother bringing her milkshakes and did not like them.

Prosecutors said Nicole did not have the sustained access necessary to account for Hannah’s repeated exposure.

The Trial Became a Battle Over Circumstantial Evidence

The state did not deny that its case lacked an eyewitness.

Instead, prosecutors argued that circumstantial evidence could prove guilt beyond a reasonable doubt.

They pointed to the pattern.

Hannah had been ingesting something containing lead.

She remembered Mann supplying capsules.

The amount inside her body indicated repeated ingestion.

Mann had access to sheets of soft lead.

The material could be scraped into pieces small enough to fit inside capsules.

He stood to receive substantial insurance proceeds if Hannah died.

The defense argued that each part of the chain contained uncertainty.

There was no forensic test presented tying the lead in Hannah’s body to the exact sheets from Mann’s office.

There was no surviving poisoned pill.

There was no recording of the alleged preparation.

There was no confession.

The jury had to decide whether the combined evidence eliminated reasonable doubt.

Mann’s Defense Called No Witnesses

The prosecution presented seven witnesses over approximately a day and a half before resting its case.

Then the defense rested as well.

Chad Morgan called no witnesses.

The strategy placed the burden where the law requires it to remain: with the prosecution. Mann did not have to prove another person poisoned Hannah. The state had to prove that he did.

Morgan maintained that the prosecution’s missing physical evidence created reasonable doubt.

For Hannah, the decision came as a surprise. She had expected a more extensive defense after waiting years for the trial.

The case went to the jury.

The Jury Found Brian Mann Guilty

Jurors began deliberating on Wednesday, June 11, 2025.

They deliberated for close to two hours before stopping for the evening. They resumed the following morning and reached a verdict after another period of deliberation.

On June 12, 2025, Brian Thomas Mann was found guilty of attempted murder.

Hannah became emotional after hearing the verdict and left the courtroom.

Her reaction was complex. Mann was the man she had married and the father of her children. A guilty verdict brought accountability, but it also meant the father of those children was going to prison.

The jury had accepted the prosecution’s circumstantial case.

Under its verdict, the unexplained illness that nearly killed Hannah was no longer only suspected poisoning.

Her husband had been found criminally responsible for trying to kill her.

Brian Mann Was Sentenced to Life in Prison

Mann returned to court for sentencing on August 27, 2025.

Prosecutors asked for life imprisonment.

Defense attorney Chad Morgan sought mercy.

Morgan County Circuit Judge Charles Elliott imposed a life sentence.

The judge made his view of the crime clear. He asked prosecutors to notify him whenever Mann became eligible for parole and said that even if he were no longer a judge at that point, he intended to travel to Montgomery to oppose Mann’s release.

The sentence brought the trial phase of the case to an end.

It did not end Mann’s legal challenges.

Mann Challenged His Conviction

Following his conviction and sentence, Mann sought to overturn the result.

His challenge continued the core argument advanced by his defense: that the state had not produced sufficient evidence to prove attempted murder beyond a reasonable doubt.

The case had depended on jurors drawing conclusions from multiple pieces of circumstantial evidence rather than from a recovered poisoned capsule, confession or eyewitness.

Mann did not succeed.

On June 18, 2026, the Alabama Court of Criminal Appeals affirmed Mann’s attempted-murder conviction. The appellate decision also left his life sentence in place.

As of September 2026, Mann is serving that sentence at Limestone Correctional Facility.

Hannah Returned to the Home Where She Had Been Poisoned

The legal consequences of the case continued into Hannah and Mann’s divorce proceedings.

In September 2025, a judge granted Hannah and her two children exclusive occupancy of the family’s Hartselle home. Mann had been returned to custody after his conviction, leaving the property unoccupied.

For Hannah, moving back required transforming a place associated with her illness.

She repainted.

She redecorated.

She cleaned the house and filled it with photographs of herself and her children.

The home that had once represented her marriage became a home for the three of them.

The divorce itself remained unresolved. Court records reported in September 2025 scheduled a bench trial in the divorce proceedings for December 14, 2026.

Hannah Built a New Life After Doctors Feared She Would Die

Hannah’s recovery stands in contrast to the prognosis doctors faced during the first days of her hospitalization.

At one point, medical staff feared she might die.

Then they feared that if she survived, neurological damage might prevent her from recovering normal cognitive function.

Three years later, she testified against Mann in a murder trial.

Hannah also completed college and earned a teaching degree. By the time she spoke with 48 Hours, she was preparing to work at a new school while raising Lincoln and Gracie.

She has spoken about continuing health consequences and about thinking at night about the fact that someone poisoned her over an extended period.

She has also said that she has forgiven Mann and hopes he can change for the sake of his family and children.

Forgiveness did not change the legal outcome.

The man she married was convicted of trying to kill her and sentenced to life.

Why the Case Was So Difficult to Prove

The attempted murder of Hannah Pettey was unusual because investigators never recovered what would traditionally be considered the murder weapon.

The lead itself was inside the victim.

Police could prove poisoning.

They could prove that it was severe.

They could present medical evidence supporting repeated ingestion.

What they could not produce was the exact capsule Hannah swallowed.

That required investigators to reconstruct the crime from opportunity, access, behaviour, medical evidence and motive.

Danny Hill’s information about the X-ray room became important because it connected Mann to a supply of lead that could be scraped into pieces small enough to conceal inside capsules.

The insurance evidence supplied the prosecution with an explanation for why a husband would spend months poisoning his wife instead of killing her through a more direct act of violence.

The jury concluded those pieces fitted together.

What Happened to Brian Mann?

Brian Thomas Mann is in prison.

He was convicted of attempted murder on June 12, 2025, after a Morgan County jury found that he was responsible for poisoning Hannah with lead.

Judge Charles Elliott sentenced him to life imprisonment on August 27, 2025.

Mann continued to challenge his conviction, but the Alabama Court of Criminal Appeals affirmed it in June 2026.

He is serving his sentence at Limestone Correctional Facility.

The conviction means the central question posed by Hannah’s medical crisis has received a legal answer.

A jury found that the person responsible for the poison entering her body was her husband.

What Happened to Hannah Pettey?

Hannah survived an attempt on her life that brought her within hours of death and left permanent medical consequences.

She recovered enough to return to her children, complete her college education and become a teacher.

She also returned with Lincoln and Gracie to the house she once shared with Mann and began remaking it as their home.

The criminal case has ended with Mann’s conviction and life sentence, while the consequences for Hannah and her family continue.

Her survival also gave prosecutors something investigators once feared they would never have: Hannah herself.

Doctors once questioned whether she would survive with enough cognitive function to tell police what happened.

Three years later, she walked into a courtroom, took the witness stand and helped secure the conviction of the man who had tried to kill her.

“The Gaslighting of Hannah Pettey” Returns to 48 Hours

48 Hours correspondent Anne-Marie Green traces the case from Hannah’s unexplained illness through the discovery of lead in her body, the suspicion surrounding her family, the investigation of Mann, Danny Hill’s crucial information about the lead-lined X-ray room and the circumstantial case that prosecutors took to trial.

The episode also gives both Hannah and Mann an opportunity to speak about the case. Mann maintained his innocence before trial and challenged the investigation, while Hannah describes the difficulty of accepting that the husband she loved could have been responsible for the illness that brought her close to death.

The title, “The Gaslighting of Hannah Pettey,” reflects more than the method of the crime. At its centre is a woman whose body was failing while the source of the danger remained hidden within her everyday life. The capsules she believed were supplements became, according to the prosecution accepted by the jury, the means by which her husband tried to kill her.

Hannah survived.

Brian Mann was convicted.

His life sentence has survived appellate review.

And the woman doctors once feared would never recover enough to tell investigators what happened is now raising her children and teaching others.

48 Hours: “The Gaslighting of Hannah Pettey” airs Saturday, September 5, 2026, at 9/8c on CBS.
