“My Uncle Joe’s Murder”: 48 Hours Investigates the Joe Shymanski Homicide on August 8 2026

Ryan Gill

CBS’s 48 Hours presents “My Uncle Joe’s Murder” on Saturday, August 8, 2026, from 10:00 to 11:00 p.m. ET/PT. The episode examines the 2023 murder of Joseph “Joe” Shymanski, a Washington, D.C.-area photographer and father whose disappearance from his Calvert County, Maryland, home led investigators across state lines and to Brandon Ross Holbrook, a man who had been romantically involved with Shymanski’s ex-wife, Heather Snyder.

The case ended with Holbrook’s conviction for first-degree premeditated murder and a sentence of life in prison without the possibility of parole. Yet one central question remains: why did Holbrook kill a man whom, according to Joe’s family and the available evidence, he had never met? Holbrook continues to deny killing Shymanski and is appealing his conviction.

The episode also carries a personal connection for 48 Hours contributor Nikki Battiste. During her reporting, Battiste discovered that she knew Snyder from their childhood in Newport, Pennsylvania. The two had attended high school together, and in 1998 Battiste crowned Snyder as her successor as homecoming queen. More than 25 years later, they met again under circumstances neither could have anticipated, with Battiste questioning Snyder about her former husband’s murder and her relationship with the man convicted of killing him.

My Uncle Joe's Murder | Full Episode

Who Was Joe Shymanski?

Joe Shymanski was a photographer, father, former teacher and familiar figure within Washington, D.C.’s creative community. He came to the area around 2000 to teach middle school history and social studies. His interests expanded into photography, which became an important part of his professional and personal life.

Friend Alton McDougle described Joe as a mentor who taught him to look at the world through a camera lens. The two became friends and business partners, working in photography at Eastern Market. Joe’s niece, Janine Shymanski, remembered an uncle whose creativity, humor and childlike eye shaped his photographs.

It was through his work at Eastern Market that Joe met Heather Snyder. Snyder was a single mother of three children and operated a vegetable business. The two began a relationship and married in July 2014. They bought a home in rural Calvert County and later had two children together, a daughter and a son.

By 2020, however, their marriage had deteriorated. The reasons for the breakdown remain disputed. Snyder has accused Joe of emotional abuse and described one incident in which she said he became physical with her. Joe’s relatives and friends have rejected that characterization, saying those allegations did not reflect the person they knew.

Joe Shymanski and Heather Snyder’s Contentious Divorce

Snyder left Maryland and returned to Newport, Pennsylvania, in 2021. Joe was devastated by the separation, according to his family and friends. The couple eventually divorced in October 2022, but their disputes did not end with the marriage.

Custody became a major source of conflict. Joe and Snyder shared legal custody of their two children, while Joe had primary physical custody during the school year. The arrangement meant the children attended school in Maryland and spent holidays and much of the summer with their mother in Pennsylvania.

Money also remained an issue. Friends and relatives of Joe claimed he had provided Snyder with substantial financial support during the marriage, including money connected to property debt and a business. Snyder has denied that she was motivated by Joe’s money.

Weeks before Joe’s death, a court reduced a financial settlement he owed Snyder. Joe had also obtained a $1 million life insurance policy several months before his murder, naming his children as beneficiaries. Because the children were minors, questions about management of their inheritance later became part of the wider dispute surrounding his estate.

Brandon Holbrook Enters the Picture

After Snyder returned to Pennsylvania, she became involved with Brandon Holbrook, a man who lived near her. She told investigators they had known each other since late 2021 or 2022 and had dated.

Holbrook also had a significant criminal history involving indecent exposure and sexual misconduct. Pennsylvania police were familiar with him from previous arrests. According to court records and reporting presented in connection with the case, Holbrook had pleaded guilty to multiple indecent-exposure offenses over the years. Another arrest involving alleged lewd conduct occurred about a month before Joe was killed.

Holbrook had also developed a relationship with Joe and Snyder’s children. According to information published by Joe’s family and friends, the children referred to him as “Uncle Brandon.” Joe’s relatives have said Joe never met Holbrook and was not aware of the full extent of Holbrook’s criminal history.

That lack of a direct relationship between Joe and Holbrook became one of the most troubling elements of the murder. Prosecutors would later argue that Holbrook developed hostility toward Joe through his relationship with Snyder and the information Snyder shared about her disputes with her former husband.

Messages Between Heather Snyder and Brandon Holbrook

Text messages became a significant part of Holbrook’s murder trial. They showed Snyder discussing her conflicts with Joe while Holbrook responded to her concerns.

In January 2023, months before the murder, Snyder complained about what she described as years of abuse. Holbrook suggested that she see a therapist but also referred to having other “solutions” in mind. Prosecutors presented the exchange as evidence relevant to Holbrook’s state of mind. His defense argued that the comment was ambiguous and could have been a joke.

Other messages addressed the custody dispute. Snyder wrote that she kept expecting “karma” to catch up with Joe and that she was tired of waiting. Snyder later told Battiste that those messages reflected her frustration and that she never told Holbrook she wanted Joe dead.

Questions also arose over whether Snyder and Holbrook had ended their romantic relationship before the murder. Snyder told investigators that she had broken up with him after his latest indecent-exposure arrest. Messages from shortly before Joe’s death, however, showed continued intimacy between them. Holbrook referred to the smell of Snyder’s hair on his pillow, while Snyder wrote that she wished she was in his bed.

Snyder has maintained that they were no longer a couple and described Holbrook as a friend at that stage. She acknowledged visiting him shortly before Joe’s murder and said their meeting involved an emotional goodbye.

Joe Shymanski Is Last Seen Alive

Joe was last known to be alive on Sunday, September 3, 2023. At about 4 p.m., he left the home of neighbors after helping with a drywall project and returned to his own house.

According to information gathered after the murder, neighbors heard gunshots around the relevant period. The sounds did not cause alarm because the homes in the rural area were separated by considerable distances and gunfire associated with target shooting was not unusual.

Prosecutors later established that Holbrook’s white truck had traveled from Pennsylvania into the area near Joe’s Maryland home that day. License plate recognition technology captured the vehicle, creating one of the first major links between Holbrook and Joe’s disappearance.

The prosecution’s case was that Holbrook had made a journey of more than 200 miles, reached Joe’s home and shot him in his driveway. Investigators would later conclude that Joe suffered a fatal gunshot wound to the head.

Heather Snyder Arrives With the Children

The following day, September 4, Snyder drove from Pennsylvania to Joe’s home to return their children. She expected Joe to be there for the custody exchange.

She arrived at about 7 p.m. Joe’s vehicle was at the property, but he did not come outside. The children entered the house, yet their father was nowhere to be found. His phone, keys and other belongings remained behind.

Snyder checked with neighbors and contacted authorities. Calvert County sheriff’s deputies were dispatched at 7:47 p.m. Snyder told them that the situation made no sense because Joe knew the children were returning.

Joe’s neighbors also found his absence troubling. They had seen him the previous afternoon and knew of no reason he would abandon his home, car, phone and children. Joe’s brother Ted later said there was no plausible reason Joe would have missed the custody exchange.

Because darkness limited the initial search, investigators returned the following morning. Daylight exposed evidence they had not seen the night before: blood in Joe’s driveway.

The missing-person investigation was becoming a homicide investigation.

Police Learn About Brandon Holbrook

Investigators questioned Snyder about Joe’s relationships, enemies and their divorce. They also asked whether she was seeing anyone.

Snyder first said she did not have a boyfriend. When investigators continued questioning her, she explained that she had been involved with someone but said the relationship had ended. She identified that man as Brandon Holbrook.

Detectives checked Holbrook’s vehicle information. A license plate reader had captured his truck near Joe’s home on September 3, the day Joe disappeared.

That discovery changed the direction of the investigation. A man whom Joe’s family said he had never met had apparently traveled from Pennsylvania to the vicinity of Joe’s Maryland home at the time Joe vanished.

Mary Shymanski, Joe’s sister, later recalled how quickly Holbrook’s name became central to the case. Maryland authorities contacted law enforcement in Pennsylvania and asked officers there to locate him.

Investigators Arrive at Holbrook’s Pennsylvania Home

On September 5, Pennsylvania authorities went to Holbrook’s property in the Reedsville area. Sergeant John Chester was familiar with Holbrook because of his previous encounters with police.

Officers encountered Holbrook and noticed an odor around him and his pickup truck. Chester described the smell from the covered truck bed as resembling death.

Holbrook worked as a driver for a facility that processed waste from chicken slaughterhouses, providing a possible explanation for animal material and odors associated with his vehicle. When questioned, however, he denied being near Joe’s home or in Maryland on the day Joe disappeared.

Investigators already had evidence that contradicted that account. His truck had been recorded in Maryland.

Police arrested Holbrook for Joe’s murder during the early hours of September 6.

Evidence Found in Holbrook’s Truck, Home and Trailer

Search warrants allowed investigators to examine Holbrook’s truck, residence and surrounding property. Inside the truck cab they found gloves and plastic sheeting. Material in the truck bed initially appeared to include human blood, although later testing determined that the blood was from an animal.

Investigators also discovered firearms, garbage bags and cleaning products, including bleach and Lysol. Wet tools were found in a trailer. In Holbrook’s garage, investigators saw an open tool case and an open package of power-saw blades, although they did not locate a matching saw.

The evidence raised the possibility that a body had been transported, dismembered and efforts made to clean the equipment or vehicle afterward. Holbrook’s work involving chicken waste also became important because investigators considered whether animal material could have been used to conceal evidence.

The most important discovery, however, would come in nearby woods rather than inside Holbrook’s home.

The Search Leads to Human Remains

Cadaver dogs led authorities along a dirt road near Holbrook’s property and into a wooded area. In a clearing near a creek, searchers discovered human remains.

Among the remains was part of a jaw containing teeth and tissue. Investigators also found a burn barrel associated with the site and piles of ash. The condition of the remains indicated that an attempt had been made to destroy the body.

Forensic testing later confirmed what Joe’s family feared. The remains belonged to Joe Shymanski.

Mifflin County Coroner Andrea Alcalde determined that Joe had suffered a gunshot wound to the head. His death was classified as a homicide.

The prosecution’s eventual theory was stark: Holbrook had traveled to Maryland, shot Joe outside his home, transported his body back to Pennsylvania, dismembered it and attempted to destroy the remains by burning them.

Questions Emerge About the Physical Evidence

The case against Holbrook contained powerful circumstantial evidence, but it was not without complications.

Investigators did not recover the murder weapon. No part of Joe’s body was discovered on Holbrook’s property itself. The material in the truck that investigators initially suspected was human blood turned out to be animal blood.

Holbrook’s phone records presented another issue. His phone connected with towers near his Pennsylvania home during the afternoon and evening when Joe disappeared. The images showing Holbrook’s truck in Maryland established the location of the vehicle, but they did not provide a clear view establishing who was driving.

These gaps became important to the defense. Holbrook’s attorneys did not need to prove another person killed Joe. They needed to persuade jurors that prosecutors could not prove beyond a reasonable doubt that Holbrook was the person who committed the murder in Joe’s driveway.

Other evidence, however, placed Holbrook at the center of the events that followed Joe’s death.

Surveillance Footage Strengthens the Case

Investigators obtained video showing Holbrook purchasing cleaning supplies in Pennsylvania on the morning after Joe’s murder. Prosecutors also presented footage that they said showed him near his white truck disposing of material later determined to include burned human remains.

The truck’s documented trip to Maryland, the cleaning purchases, the location of Joe’s remains near Holbrook’s home and the footage surrounding the disposal of those remains created a chain of circumstantial evidence.

Prosecutors argued that Holbrook had also used material connected to the chicken-processing business to conceal evidence. His access to animal waste provided an explanation for why animal blood and material could be present in his truck after prosecutors said it had been used to transport Joe’s body.

The defense conceded that evidence connected Holbrook to events after Joe’s death but disputed whether prosecutors could prove he was the person who pulled the trigger.

Joe’s Family Suspects Someone Else Was Involved

Joe’s relatives and several friends became convinced that Holbrook had not acted without influence from someone else. Their suspicions focused on Heather Snyder.

Those suspicions have not resulted in criminal charges against Snyder, and authorities have not publicly identified her as a suspect in Joe’s murder. Snyder has denied planning, encouraging, assisting or covering up the killing.

Joe’s relatives nevertheless pointed to the custody dispute, financial conflict, Snyder’s relationship with Holbrook and her statements to investigators as reasons for their doubts. They also questioned why Snyder contacted police within an hour of discovering Joe absent but waited more than two hours before contacting his immediate family.

They believed her initial description of her relationship with Holbrook did not match the messages later recovered from their phones.

Joe’s niece Janine has said she believes Snyder found someone willing to remove Joe from her life. Friend Alton McDougle has expressed similar suspicions. These are allegations and personal beliefs, not findings of guilt.

A Conversation Before Joe’s Death Haunts His Friend

McDougle has described a conversation with Joe shortly before the murder that took on new significance after his death.

Joe told him that Snyder would be bringing the children directly to his home rather than conducting the custody exchange at the halfway point they had often used. McDougle said he warned Joe that he did not trust the situation and did not want Snyder coming to the house.

Joe did not share his concern.

After the murder, McDougle was left wondering whether events would have unfolded differently if Joe had insisted on another exchange location. The conversation became one of the painful memories surrounding a crime that Joe’s loved ones believe was tied in some way to the conflict in his personal life.

Additional Remains Raise Another Question

Weeks after Holbrook’s arrest, Mary Shymanski visited the area where investigators had discovered her brother’s remains. She found additional burned remains.

One explanation was that search teams had missed them during the first examination of the wooded area. Coroner Andrea Alcalde, however, told 48 Hours that she considered another possibility: that the additional material had been deposited after the original search.

If that happened, someone other than the incarcerated Holbrook would have needed to place it there.

The issue added another unresolved element to the case. Maryland authorities did not publicly endorse the theory that another person had returned to dispose of additional remains. The question nevertheless became useful to Holbrook’s defense, which argued that the evidence left open the possibility of another participant.

Brandon Holbrook Goes on Trial for Murder

Holbrook’s trial began on March 31, 2025. Prosecutors sought a conviction for premeditated first-degree murder.

Their case reconstructed what they said was a planned interstate killing. Holbrook drove from Pennsylvania to Maryland, shot Joe, transported his body north, attempted to conceal evidence using material associated with the chicken-processing operation and disposed of Joe’s burned and dismembered remains near his home.

Prosecutors brought the burn barrel into court and presented surveillance footage, vehicle records, physical evidence and communications between Holbrook and Snyder.

The defense pursued a different strategy. Attorneys Brendan Callahan and Thomas Mooney sought to create reasonable doubt by focusing attention on the unanswered questions surrounding Snyder, the custody dispute and the lack of direct forensic proof placing Holbrook in Joe’s driveway.

Heather Snyder Becomes a Major Issue at Trial

Although Snyder was not on trial, her name was reportedly mentioned more than 400 times during the proceedings.

The defense argued that Snyder had clearer reasons to want Joe gone than Holbrook did. Attorneys cited the contentious custody battle and the financial issues between the former spouses. They also raised the $1 million life insurance policy benefiting Joe and Snyder’s children.

Snyder told 48 Hours that she did not know about the policy before Joe died.

The defense also highlighted Snyder’s communications with Holbrook and challenged her statements that their romantic relationship had ended. Messages exchanged shortly before the murder indicated a level of intimacy that Holbrook’s lawyers argued conflicted with the picture she had initially given investigators.

None of that established that Snyder participated in the murder. Prosecutors had evidence showing she was in Pennsylvania around the time Joe was killed.

Surveillance Video Provides Snyder With an Alibi

One significant piece of evidence separated suspicion about Snyder from proof that she personally killed Joe.

Surveillance footage showed Snyder buying pizza in Pennsylvania around the period when Joe disappeared in Maryland. She was approximately three hours away and could not have been physically present at Joe’s home when prosecutors said the shooting occurred.

Holbrook’s defense acknowledged that fact.

The attorneys instead argued that physical absence would not exclude other possible roles, such as encouraging another person or knowing about a plan. Prosecutors did not charge Snyder with any such conduct.

Snyder has denied every allegation that she had prior knowledge of the killing or encouraged Holbrook to hurt Joe.

Heather Snyder Invokes the Fifth Amendment

Both sides wanted Snyder to answer questions at Holbrook’s trial. When called to testify, however, she invoked her Fifth Amendment privilege against self-incrimination and declined to answer substantive questions.

The decision became another source of suspicion for Joe’s relatives and Holbrook’s attorneys. Defense lawyer Brendan Callahan noted that the privilege protects a witness when truthful answers could potentially expose that person to criminal liability.

Invoking the Fifth Amendment does not establish guilt.

Snyder later told Battiste that a criminal attorney advised her not to testify because she feared her statements could be distorted or used against her. She maintained that she had nothing to hide and played no role in Joe’s death.

Prosecutors Argue Holbrook Was Obsessed With Snyder

Prosecutors offered a motive that did not require Snyder to have ordered the killing. Their argument was that Holbrook’s feelings for Snyder and hostility toward Joe became powerful enough for him to act on his own.

They introduced evidence suggesting Holbrook had been near Joe’s Maryland home months before the murder. A vehicle he owned was photographed in the area about seven months before Joe died.

The communications between Snyder and Holbrook also showed that he knew about her complaints concerning Joe. Prosecutors used the January 2023 exchange about “other solutions” as part of their effort to show the development of Holbrook’s thinking.

The state argued that Holbrook had absorbed Snyder’s accounts of the marriage, divorce and custody fight and developed his own reason to eliminate Joe.

What prosecutors could not establish was why Holbrook chose September 3, why he allegedly decided murder was the solution, or whether anyone else knew what he planned to do.

The Jury Reaches a Verdict in 80 Minutes

Holbrook did not testify.

During closing arguments, his lawyers emphasized that no witness had placed him in Joe’s driveway and that the images of his vehicle did not establish who was behind the wheel. They argued that the prosecution had strong evidence connecting Holbrook to the disposal of Joe’s remains but insufficient proof that he committed the murder itself.

Jurors rejected that argument.

After approximately 80 minutes of deliberation, the jury found Holbrook guilty on April 9, 2025. He was convicted of first-degree premeditated murder, along with firearm and evidence-related offenses connected to Joe’s death.

For Joe’s family, the verdict confirmed Holbrook’s criminal responsibility for the killing. It did not answer every question surrounding the case.

Brandon Holbrook Is Sentenced to Life Without Parole

Holbrook returned to court for sentencing on July 18, 2025. Joe’s relatives and friends filled the courtroom and described the effect his murder had on their lives.

The court sentenced Holbrook to life in prison without the possibility of parole.

Friends and relatives used the proceeding not only to remember Joe but also to express their belief that unanswered questions remained. A photo montage presented during sentencing included recordings Joe had made before his death in which he discussed his concerns about Snyder and the effect he believed their conflict was having on the children.

The judge indicated that Holbrook’s conviction did not necessarily mean every issue surrounding the case was closed.

Holbrook has appealed his conviction. Because of that appeal, Calvert County State’s Attorney Robert Harvey told 48 Hours that the case remains open.

Nikki Battiste Confronts Someone From Her Past

The story became unusual for 48 Hours when Battiste realized she had known Snyder decades earlier.

Both grew up in Newport, Pennsylvania. Battiste was her high school’s 1997 homecoming queen, and Snyder succeeded her. A photograph captured Battiste placing the crown on Snyder in 1998.

They had not communicated for more than 25 years.

Their reunion took place not at a school event but during an interview about murder. Snyder agreed to speak with Battiste and said she wanted an opportunity to answer the accusations surrounding her.

Battiste questioned her about Joe, Holbrook, the custody battle, their messages and the suggestion that Holbrook might have acted because of Snyder.

Heather Snyder Denies Any Role in Joe’s Murder

Snyder told Battiste that she never told Holbrook she wanted Joe dead and that Holbrook never told her he intended to kill him.

Asked about Holbrook’s reference to having other “solutions” for her problems with Joe, Snyder said she interpreted the comment as a joke. She also said she did not know whether her complaints about Joe could have triggered something in Holbrook.

Snyder acknowledged that she continued to have feelings for Holbrook even after Joe’s murder. She told Battiste she still had love for him while also describing what happened to Joe as horrific.

She said she believes something caused Holbrook to snap but maintains she had no knowledge of a plan to kill Joe.

Snyder also defended her decision to call police soon after arriving at Joe’s house, saying her divorce attorney advised her to make the report.

A Jail Call Adds Another Mystery

Before Holbrook was sentenced, Snyder accepted a telephone call from him in jail.

During the recorded conversation, Snyder complained that Joe’s family was trying to prove she had done something wrong. Holbrook told her he would never say she had anything to do with the case.

Snyder asked for the truth.

Holbrook responded that he would like to tell her everything he knew but would not do so on a recorded telephone line. He then denied ever seeing, speaking to or interacting with Joe during Joe’s lifetime.

That statement conflicts with the jury’s verdict that Holbrook was the man who committed Joe’s premeditated murder.

It also left another unanswered question. If Holbrook insists he never encountered Joe, what did he mean when he said there were things he could tell Snyder but would not discuss on a recorded call?

Questions About a Gun Given to Snyder

Another issue raised during the investigation concerned a firearm that Snyder said Holbrook had given her before Joe’s murder.

Snyder disclosed the weapon to authorities, but Holbrook’s defense criticized investigators for not collecting and examining it sooner. No recovered bullets or cartridge cases provided a way to determine whether that firearm had been used to kill Joe.

Snyder told 48 Hours the gun was intended for target practice and had been locked in her closet.

The murder weapon has not been publicly identified as recovered.

For Holbrook’s defense, the gun represented another example of what the attorneys considered insufficient investigation of alternative possibilities. For Snyder, it became another circumstance that she said had been interpreted as evidence of involvement despite her denial of any role in the killing.

Joe’s Family Still Wants to Know Why He Was Killed

Holbrook’s conviction answered the legal question placed before the jury: prosecutors proved beyond a reasonable doubt that he murdered Joe Shymanski.

It did not provide a complete explanation for the crime.

Joe and Holbrook had no known personal relationship. Joe’s family says the two men had never met. Yet prosecutors established that Holbrook’s truck traveled hundreds of miles to Maryland before Joe was shot and that evidence connected Holbrook to the destruction and disposal of Joe’s remains in Pennsylvania.

The absence of a clear explanation for why Holbrook would undertake such an extreme crime remains at the center of the family’s search for answers.

Joe’s relatives believe Snyder knows more than she has disclosed. Snyder says that belief is wrong and that she has become the target of a true-crime narrative built around circumstances she did not create.

No Charges Have Been Filed Against Heather Snyder

The distinction between suspicion and established fact is important in the Shymanski case.

Heather Snyder has not been charged with Joe Shymanski’s murder, has not been publicly identified by authorities as a suspect and has denied involvement. Evidence also places her in Pennsylvania when Joe was killed.

Calvert County’s top prosecutor has said authorities conducted a thorough investigation but declined to discuss further investigative details because Holbrook’s case remains under appeal.

When Battiste asked Pennsylvania Detective Jessica Aurand whether Snyder was currently under investigation or whether investigators believed she was involved, Aurand declined to answer those questions.

That refusal does not establish Snyder’s involvement. It does, however, leave the public without a definitive answer concerning whether authorities consider every aspect of the investigation complete.

The Lasting Impact on Joe Shymanski’s Children and Family

At the center of the case are Joe’s two young children. They arrived at their father’s house expecting a routine custody exchange and instead entered a chain of events that revealed he had been murdered.

They lost their father, their home life changed, and the conflict between the adults around them continued after his death.

Snyder told 48 Hours that the children retain happy memories of their father and that she tries to preserve those memories. She has also said that Joe’s relatives cannot expect a normal relationship with the children while publicly accusing her of involvement in his death.

Joe’s relatives, meanwhile, continue to grieve both his murder and the resulting changes to their family. His brother Ted summarized their view in painful terms, saying that if Joe had never met Snyder, he believes his brother would still be alive.

Joe Shymanski’s Legacy Lives Through Photography

Joe’s family and friends have sought ways to ensure that his life is remembered for more than the violence surrounding his death.

A scholarship established in his name supports photography students in Washington, D.C., public high schools. It connects Joe’s memory to the creative work that defined much of his life.

His friends and relatives have also created a campaign centered on the message “Live Like Joe,” preserving photographs, memories and information about the case while asking anyone with knowledge of the circumstances surrounding the murder to come forward.

For them, Holbrook’s conviction brought accountability but not closure. They continue to seek an explanation for how a man Joe apparently never met came to his Maryland home and killed him.

“My Uncle Joe’s Murder” Examines a Case That Still Has Unanswered Questions

48 Hours: “My Uncle Joe’s Murder” reconstructs a case that began with a father missing from his home and ended with evidence stretching from a bloodstained Maryland driveway to burned human remains in the Pennsylvania countryside.

The investigation produced a conviction. Brandon Ross Holbrook was found guilty of Joe Shymanski’s first-degree premeditated murder and sentenced to life in prison without parole. The evidence convinced jurors in less than two hours, and Holbrook remains imprisoned while appealing the verdict.

What the trial did not produce was a complete motive. Holbrook had been involved with Joe’s ex-wife, knew about her disputes with Joe and had expressed thoughts prosecutors argued demonstrated hostility toward him. Yet the precise reason he crossed state lines and killed a man he had apparently never met remains unresolved.

Joe’s family believes there is more to the story. Snyder insists there is not and says she neither knew about nor participated in Holbrook’s actions. No charge has been filed against her.

That divide is at the heart of “My Uncle Joe’s Murder.” The episode examines both the evidence that sent Holbrook to prison and the questions Joe Shymanski’s family continues to ask more than two years after his death.

48 Hours: “My Uncle Joe’s Murder” airs Saturday, August 8, 2026, from 10:00 to 11:00 p.m. ET/PT on CBS.
