Who Was Julie Harding & What Happened to Her? 2026 Update & Profile

by · October 22, 2026

Julie Harding was a California Highway Patrol captain whose 22-year law enforcement career ended amid an investigation into the murder of her estranged husband, Tennessee businessman Michael Harding. Prosecutors alleged that she had arranged for a California man, Thomas O’Donnell, to kill Michael during a bitter divorce and financial dispute.

Her story is examined in “48 Hours: The Mansion Above Dale Hollow Lake,” airing Saturday, October 24, 2026, at 10/9c on CBS. Correspondent Peter Van Sant investigates the September 2022 murder, the evidence connecting Julie to the suspected murder-for-hire plot and the events that preceded her death in Tennessee less than three months later.

Julie was a respected senior officer who had risen through the California Highway Patrol to become commander of its Yuba-Sutter area office. She had married Michael in 2019, and the couple purchased a substantial home near Dale Hollow Lake in Tennessee. Their marriage deteriorated, leading to divorce proceedings and disputes over money and property.

On September 19, 2022, Michael was shot dead inside a vacant house in Burkesville, Kentucky, after responding to a fictitious heating and air-conditioning service call. Investigators traced the appointment to O’Donnell, a California resident who had been in extensive contact with Julie.

O’Donnell was arrested on December 8, 2022. Julie was arrested in Tennessee on a separate criminal trespassing allegation that same day. On December 10, she was found dead at the couple’s Tennessee property in what authorities described as an apparent suicide.

Julie died before prosecutors could bring a murder-conspiracy case against her. O’Donnell was convicted of Michael’s murder in May 2026 and received a life sentence. Julie was never tried or convicted of involvement in the killing.

Who Was Julie Harding?

Julie Harding was a 49-year-old California Highway Patrol captain who had spent more than two decades in law enforcement. She joined the CHP in 1999 and rose to become commander of the department’s Yuba-Sutter area office in Northern California.

Her career placed her in a leadership role within one of California’s principal statewide law enforcement agencies. As a captain, she held responsibilities involving officers, public safety operations and administration.

Julie became commander of the Yuba-Sutter office in 2018, according to statements from the California Highway Patrol. The position placed her in charge of a regional area serving communities north of Sacramento.

Her professional background drew attention after investigators began examining her possible involvement in the murder of her estranged husband. The allegation that a police commander had arranged a contract killing became a central aspect of the case.

Julie was on leave from the CHP at the time of her death in December 2022. Her career ended without a criminal trial determining whether she had participated in Michael’s murder.

Julie Harding’s Career With the California Highway Patrol

Julie joined the California Highway Patrol in 1999 and spent approximately 22 years with the department before the events that brought her under criminal scrutiny.

She advanced through the organisation and became captain of the Yuba-Sutter area office in 2018. The role involved supervising law enforcement operations across a region of Northern California.

Her position gave her professional experience with criminal investigations, law enforcement procedures and the responsibilities of command. Prosecutors later alleged that she had participated in a murder-for-hire arrangement involving her estranged husband.

The allegation attracted attention because of the contrast between her professional responsibility to uphold the law and the suspected conspiracy investigators were examining.

A retired CHP sergeant who had worked under Julie later spoke to KCRA about changes in her behaviour during the period preceding Michael’s death. He recalled concerns that developed as the couple’s marriage deteriorated.

Those recollections formed part of the reporting on the case, but Julie’s death prevented a court from determining her criminal responsibility for the alleged plot.

Julie Harding’s Marriage to Michael Harding

Julie married Michael Harding in 2019. Michael was a businessman who operated Around the Clock Heating and Air, a heating and air-conditioning company.

The couple had connections to Northern California before purchasing a large property in Celina, Tennessee, near Dale Hollow Lake.

Their plans involved establishing a life together in Tennessee while Julie continued her career with the California Highway Patrol.

Michael developed his business in Tennessee, while Julie maintained her professional responsibilities in California. Their marriage involved periods of living in different states.

By 2022, the relationship had deteriorated. Julie filed for divorce in May, approximately three years after the couple married.

The separation developed into a dispute involving money, property and personal relationships. Those circumstances became part of the investigation into Michael’s murder.

The Mansion Near Dale Hollow Lake

Julie and Michael purchased a substantial home in Celina, Tennessee, near Dale Hollow Lake, a reservoir extending across parts of Tennessee and Kentucky.

The property represented their plans to establish a future together outside California. Michael had relocated his business to Tennessee, while Julie continued working in Northern California.

The home became part of the couple’s financial and property interests as their marriage deteriorated. Their divorce proceedings brought those interests into dispute.

The property later became the location of Julie’s death on December 10, 2022, after investigators had begun examining her possible involvement in Michael’s murder.

Its connection to both the couple’s plans and the deaths that followed provides the title for the 48 Hours episode, “The Mansion Above Dale Hollow Lake.”

Why Did Julie Harding File for Divorce?

Julie filed for divorce from Michael in May 2022. Their marriage had become strained, and financial disagreements formed part of the separation.

Prosecutors alleged that Julie withdrew approximately $220,000 from three joint bank accounts without Michael’s consent. The transactions became part of the evidence examined during the murder investigation.

Michael had also begun a relationship with another woman. The new relationship became part of the conflict surrounding the divorce.

Investigators later examined allegations that Julie had entered the woman’s Tennessee property without permission. Those allegations resulted in a criminal trespassing arrest in December 2022.

The financial dispute and the breakdown of the marriage became central to the prosecution’s theory that Julie had arranged for Michael to be killed.

Julie died before she could respond to those allegations in a murder-conspiracy trial. The claims concerning her role were presented through the investigation and the subsequent prosecution of Thomas O’Donnell.

The Financial Dispute Involving $220,000

One of the most significant issues in the Hardings’ separation involved money held in joint bank accounts.

According to prosecutors, Julie withdrew approximately $220,000 from three accounts without Michael’s consent in May 2022, around the time she filed for divorce.

Investigators examined the transactions as part of the suspected motive for Michael’s murder. The prosecution argued that the financial dispute provided a reason for Julie to arrange his killing.

The withdrawals also formed part of a wider conflict involving property and the couple’s separation.

The prosecution’s theory relied on more than the financial transactions. Investigators examined telephone records, travel information and communications connecting Julie to Thomas O’Donnell.

The financial allegations were never tested in a criminal trial against Julie because she died before such proceedings could take place.

How Did Julie Harding Become Connected to Thomas O’Donnell?

Thomas O’Donnell was a California resident from Napa who became the principal suspect in Michael Harding’s murder.

Investigators discovered that Julie and O’Donnell had been in extensive telephone contact during the months preceding Michael’s death.

According to prosecutors, telephone records documented 194 calls between the two during the three months before the September 2022 shooting.

The frequency and timing of the communications attracted attention as detectives examined whether the killing had been arranged.

Investigators also found location evidence placing O’Donnell near Julie’s Sacramento-area home shortly before Michael was murdered.

Prosecutors alleged that the communications and travel records supported a conspiracy in which Julie arranged for O’Donnell to kill her estranged husband.

The Alleged Murder-for-Hire Plot Against Michael Harding

Prosecutors alleged that Julie Harding had arranged for Thomas O’Donnell to murder Michael as the couple’s divorce and financial dispute continued.

The plan involved luring Michael to a vacant property in Burkesville, Kentucky, through a fictitious heating and air-conditioning service request.

According to the prosecution, O’Donnell obtained access to the house by posing as someone connected to the real estate transaction. He secured the lockbox code and arranged for Michael to attend the property.

On September 19, 2022, Michael travelled to the house believing he was responding to a legitimate customer.

He was shot multiple times and died inside the vacant property. His body was discovered by a real estate agent one week later.

Investigators alleged that Julie had organised the killing through O’Donnell, but she died before facing trial over that accusation.

What Happened to Michael Harding in September 2022?

Michael Harding was 53 when he was murdered on September 19, 2022. He operated Around the Clock Heating and Air and had travelled to Burkesville, Kentucky, for what appeared to be a service appointment.

The property was vacant and listed for sale. Prosecutors established that the appointment had been arranged through a deception intended to bring Michael to the house.

Michael was shot multiple times. His body remained inside the property until September 26, when a real estate agent arrived to show the home to prospective buyers.

The discovery prompted an investigation by Kentucky State Police, with assistance from the FBI and authorities in Tennessee and California.

Detectives examined the service call, the property’s access arrangements and communications connected to the suspected killer.

The investigation led to Thomas O’Donnell and raised questions about Julie’s involvement in arranging the shooting.

Michael Harding’s Warnings About His Wife

Before his death, Michael expressed concerns about his safety to friends, according to accounts published after the murder.

One friend recalled a fishing trip during which Michael suggested that investigators should examine Julie if something happened to him.

The friend discussed the conversation in KCRA’s October 2026 documentary Hometown Tragedy: The Broken Oath.

The recollection gained significance after Michael was found murdered in Kentucky and investigators began examining Julie’s communications with O’Donnell.

The account suggested that Michael had feared the possibility of harm during the breakdown of his marriage.

It remained a witness recollection rather than a judicial finding about Julie’s intentions.

How Investigators Linked Julie Harding to the Murder

Investigators examined communications between Julie Harding and Thomas O’Donnell after identifying him as a suspect in Michael’s murder.

Telephone records documented 194 calls between the two during the three months preceding the shooting. Detectives considered the timing of those communications alongside travel and location evidence.

Records also placed O’Donnell near Julie’s Sacramento-area home shortly before Michael was killed.

The prosecution alleged that the contact demonstrated coordination between the two during the period when the murder was being planned.

Investigators examined the financial dispute between Julie and Michael as a possible motive for the killing.

The evidence became part of the murder prosecution against O’Donnell, but Julie died before a court could determine whether she had participated in the alleged conspiracy.

The CHP Colleague Who Became Suspicious of Julie Harding

A retired California Highway Patrol sergeant who had worked under Julie spoke about his concerns in KCRA’s documentary Hometown Tragedy: The Broken Oath.

He described changes in her behaviour during the period preceding Michael’s disappearance and said he had become concerned about her conduct.

The former colleague also recalled Julie’s reaction when she learned that Michael’s body had been found.

He described her response as intense and said it caused him to question whether she was attempting to influence how he remembered the conversation.

His recollections were part of the documentary’s examination of Julie’s conduct during the investigation.

They provided a perspective from someone who had known her through her law enforcement career, but they did not establish her guilt in the alleged murder plot.

Julie Harding’s Dispute With Michael’s Girlfriend

After Michael Harding’s death, Julie became involved in a dispute with a woman who had been in a relationship with him during their separation.

Police reports described an incident on October 10, 2022, at a property in Murfreesboro, Tennessee. The woman alleged that Julie entered the property and took a dog named Charlie, which Michael and Julie had shared.

Investigators examined footage from a Ring security camera. According to reporting on the case, the recording showed Julie approaching the dog, placing a leash around its neck and taking it from the property.

The woman made another complaint on October 13, alleging stalking and harassment. Those reports led to criminal proceedings involving Julie.

The dispute became part of the wider investigation into the breakdown of the Hardings’ marriage, although the allegations concerning the dog were separate from the murder charge brought against Thomas O’Donnell.

Julie Harding’s Arrest in Tennessee

In December 2022, authorities took Julie Harding into custody in Tennessee on a criminal trespassing allegation connected to the incident at Michael’s girlfriend’s property.

The arrest occurred on December 9, according to early reporting based on Rutherford County law enforcement records. Thomas O’Donnell had been arrested at Sacramento International Airport on December 8 in connection with Michael’s murder.

Julie was released from custody following her arrest. The trespassing case concerned the alleged entry onto another person’s property, rather than a criminal charge for Michael’s killing.

At the time, investigators were examining her suspected involvement in the murder-for-hire plot. She had not been convicted of a crime connected to Michael’s death.

Her release was followed by her death in Tennessee on December 10, bringing the possibility of a prosecution against her to an end.

What Happened to Julie Harding on December 10, 2022?

On December 10, 2022, Julie Harding was found dead outside the property she and Michael had purchased in Celina, Tennessee.

Her body was discovered near the driveway by a postal worker and another person. She had suffered a gunshot wound and was 49 years old.

The Clay County Sheriff’s Office responded to the scene, and the Tennessee Bureau of Investigation became involved in examining the circumstances of her death.

Authorities reported that there was no indication of foul play. Subsequent reporting described the death as suicide.

Julie’s death occurred less than three months after Michael was murdered in Kentucky and within days of the arrests involving O’Donnell and Julie herself.

The discovery added another death to an investigation that had involved law enforcement agencies in three states.

How Did Julie Harding Die?

Julie Harding died from a gunshot wound at the couple’s property in Celina on December 10, 2022. Authorities found her outside the home near the driveway.

The Tennessee Bureau of Investigation examined the circumstances, and law enforcement reported no evidence indicating that another person had caused her death.

The death was described in subsequent reporting as suicide. Julie was 49 years old.

The timing attracted attention because O’Donnell had been arrested in California two days earlier and Julie had faced a separate arrest in Tennessee.

The public record does not establish a definitive explanation for Julie’s personal state of mind or her reasons for taking her life. Her death also cannot be treated as proof that she had participated in Michael’s murder.

It did, however, mean that she would never face a jury over the allegations that investigators were developing against her.

Why Was Julie Harding Never Tried for Michael’s Murder?

Julie Harding died before prosecutors could bring the alleged murder-for-hire conspiracy against her to trial.

Investigators suspected that she had arranged for Thomas O’Donnell to kill Michael during their divorce. The evidence they examined included telephone records, financial transactions and O’Donnell’s movements.

Her death in December 2022 prevented prosecutors from presenting a criminal case against her in court.

As a result, Julie was never convicted of organising Michael’s murder. The allegations concerning her involvement remained part of the prosecution’s theory against O’Donnell.

The distinction is significant because the jury that convicted O’Donnell determined his criminal responsibility for the killing, not Julie’s guilt.

Thomas O’Donnell’s Murder Trial in 2026

Thomas O’Donnell stood trial in Cumberland County, Kentucky, beginning in April 2026. Prosecutors accused him of killing Michael Harding after luring him to a vacant property through a fictitious HVAC service call.

The state presented evidence concerning the prepaid telephone, access to the property, travel records and communications with Julie Harding.

Prosecutors alleged that Julie had arranged the killing and that O’Donnell had carried it out. The financial dispute between the Hardings formed part of the alleged motive.

The defence challenged the evidence and argued that prosecutors had not proved O’Donnell’s responsibility for the shooting. His attorneys also questioned the evidence supporting the alleged payment arrangement.

The jury considered the evidence concerning O’Donnell’s actions and his relationship with Julie before returning a verdict.

Thomas O’Donnell Convicted of Michael Harding’s Murder

On May 1, 2026, a Kentucky jury convicted Thomas O’Donnell of murdering Michael Harding.

The verdict followed testimony about the fictitious service appointment, the shooting and the communications linking O’Donnell to Julie.

During the penalty phase on May 4, jurors recommended life imprisonment. The recommendation was unanimous and represented the most severe sentencing option available to them.

The case established O’Donnell’s responsibility for Michael’s murder, but it did not result in a criminal verdict against Julie.

O’Donnell continued to maintain his innocence after the conviction. In an October 2026 documentary interview, he acknowledged being in the area around the time of the killing but disputed the allegation that he was the gunman.

What Happened to Julie Harding’s Law Enforcement Career?

Julie was on leave from the California Highway Patrol when she died in December 2022.

She had joined the department in 1999 and served as commander of the Yuba-Sutter area office from 2018. Her career spanned more than two decades and included senior responsibilities within the organisation.

The murder investigation brought attention to her professional background because prosecutors alleged that she had helped organise a killing while holding the rank of captain.

Her death ended her career before any criminal trial could establish whether the allegations against her were true.

The CHP confirmed her service history following her death. The subsequent prosecution focused on O’Donnell, whose conviction came in May 2026.

Julie Harding’s Story in Hometown Tragedy: The Broken Oath

In October 2026, KCRA released Hometown Tragedy: The Broken Oath, a documentary examining the murder investigation involving Julie and Michael Harding.

Investigative journalist Lysée Mitri, who had followed the case for nearly four years, interviewed people connected to the investigation, including Michael’s friends and a retired CHP sergeant who had worked under Julie.

The documentary examined Julie’s conduct before and after Michael’s disappearance, the evidence concerning the alleged murder-for-hire arrangement and the effect of the case on Michael’s family.

It also featured Thomas O’Donnell speaking after his conviction. He maintained his innocence and provided his account of his movements around the time of the murder.

The programme was made available through KCRA and the Very Local streaming service.

Julie Harding’s Story Featured on 48 Hours

Julie Harding’s life, career and death are examined in 48 Hours: The Mansion Above Dale Hollow Lake, reported by Peter Van Sant.

The episode airs Saturday, October 24, 2026, at 10/9c on CBS and explores the investigation into Michael Harding’s murder in Kentucky.

The programme examines the couple’s marriage, their financial dispute, Julie’s connection to Thomas O’Donnell and the evidence prosecutors used to establish a murder-for-hire plot.

It also revisits Julie’s death in Tennessee and the criminal proceedings that resulted in O’Donnell’s conviction in May 2026.

The case involves a senior law enforcement officer accused of participating in a conspiracy to kill her estranged husband, but who died before the allegations could be tested in court.

What Was the Final Outcome of Julie Harding’s Case?

Julie Harding died on December 10, 2022, at the age of 49. Her death was described as suicide, and authorities reported no indication of foul play.

At the time, investigators suspected that she had arranged for Thomas O’Donnell to murder her estranged husband, Michael Harding, who was shot dead in Kentucky on September 19, 2022.

Julie was never tried or convicted of involvement in Michael’s murder. Her death prevented prosecutors from bringing the alleged conspiracy against her before a jury.

O’Donnell was convicted of murder on May 1, 2026. Jurors recommended life imprisonment on May 4, establishing the principal criminal outcome of the case.

Julie’s story remains central to the investigation because of her law enforcement career, her relationship with Michael and the evidence that prosecutors alleged connected her to the killing.

48 Hours: The Mansion Above Dale Hollow Lake airs Saturday, October 24, 2026, on CBS, with streaming availability through Paramount+.
