48 Hours' Mansion Above Dale Hollow Lake Video: The Fake Repair Call That Led to Mike Harding
On September 19, 2022, HVAC contractor Mike Harding, 53, drove to a vacant property in Burkesville, Kentucky, believing he had a repair job. He had been lured there. His body, shot four times, was found about a week later by people touring the property with a real estate agent.
Most 48 Hours episodes revisit a case years after its legal end. This one arrives close behind it: the episode, reported by Peter Van Sant, first aired October 24, 2026, five months after a Kentucky jury convicted Thomas O'Donnell of Harding's murder, and it was published on YouTube on October 29, 2026, where it passed 350,000 views in its first day. That timing gives the hour a completeness the series does not always have — a beginning, an investigation, and a verdict.
What holds the episode together is not the "cursed" mansion of its title but a chain of phone evidence: a prepaid phone, a fabricated identity, a lockbox code, and 194 documented contacts that connected the man accused of pulling the trigger to Harding's estranged wife, California Highway Patrol commander Julie Harding.

What the Video Covers
The episode opens with the discovery. On September 26, 2022, a real estate agent brought prospective buyers to a vacant property in Burkesville, Kentucky. In a cottage on the grounds, they found a man on the floor with gunshot wounds. He was identified as Michael "Mike" Harding, 53, an Army and Navy veteran who ran an HVAC business, Around the Clock Heating and Air, after relocating from California to Tennessee. An autopsy found he had been shot four times, twice in the head and twice in the torso, and investigators estimated his body had been there for about a week.
Harding's phone, found at the scene, told investigators how he got there. On September 19, 2022, he had been contacted about an HVAC repair at the empty house. According to prosecutors, the request was fabricated: Thomas O'Donnell used a prepaid phone and a false identity to obtain the lockbox code from a real estate agent, then used the same phone to call Harding out. Kentucky State Police Detective BJ Burton tells Van Sant that the messages and calls made it obvious early on that Harding had been lured to the house.
The investigation then turned to Harding's divorce. He and his estranged wife, Julie Harding — a California Highway Patrol commander with 22 years on the force — were living separately, she in California and he in Tennessee, near the couple's home above Dale Hollow Lake in Celina. Reporting in the episode describes more than $200,000 withdrawn from their joint accounts as the marriage broke down, and investigators say they believed Julie feared losing hundreds of thousands of dollars in the divorce. Her phone records showed 194 contacts with O'Donnell in the months before the murder, and the prepaid phone had been located together with O'Donnell's own phone weeks before Harding died. O'Donnell's only connection to Harding, Burton notes, was through Julie.
On December 8, 2022, O'Donnell was arrested at Sacramento International Airport. Julie Harding was arrested the same day on an unrelated trespassing charge and released; two days later she was found dead at the Celina home, and authorities determined she had died by suicide. The episode is careful on a point viewers should hold onto: prosecutors alleged at trial that she solicited and hired O'Donnell, but Julie Harding was never indicted, tried, or convicted in connection with her husband's death. The case against O'Donnell went to trial in April 2026; on May 1, 2026, a Cumberland County jury convicted him of murder after about two hours of deliberation, and he was sentenced to life in prison with the possibility of parole after 20 years. His appeal was reported as pending when the episode aired.
Strengths
The verdict is in. Because O'Donnell's trial ended in May 2026, this is a rare 48 Hours hour that can follow a case all the way from a 911-era discovery to a conviction, a sentence, and a pending appeal — no "still awaiting trial" asterisk.
The phone-evidence chain is clearly taught. The prepaid phone's activation, its co-location with O'Donnell's phone, and the 194 contacts with Julie Harding form a compact, understandable lesson in how investigators build a conspiracy case without a witness to the shooting itself.
Harding stays a person, not a premise. Van Sant speaks with Harding's family and friends, and the episode keeps his work, his military service, and his fear during the divorce in view alongside the forensic timeline.
Weaknesses
The "cursed house" framing is the weakest thread. The Celina mansion's local legend gives the episode its title, but the folklore sits uneasily next to a murder case and adds little to understanding what happened in Burkesville.
One central account can never be tested. Julie Harding died before any charge was brought against her, so the alleged motive — fear of losing money in the divorce — remains investigators' theory, presented without her defense. The episode notes her status, but viewers should keep the allegation and the conviction distinct.
A dense, multistate timeline. California, Tennessee, Kentucky, and a prepaid phone traced to Texas all feature in 42 minutes. The geography and the two Harding properties — the Celina mansion and the Burkesville cottage — take effort to keep straight.
Who Should Watch
- 48 Hours regulars — a complete, verdict-included episode reported by Peter Van Sant, with a trial only months old.
- Phone-evidence and investigation followers — the prepaid-phone and call-record chain is the clearest part of the hour.
- Murder-for-hire case viewers — a careful example of how an alleged hiring plot is reconstructed after the fact.
- Viewers who prefer closed cases — a conviction and sentence are on the record, with only the appeal outstanding.
8/10
A complete and clearly told account of a luring murder — the phone evidence is well explained, the fresh conviction closes the arc, and Harding himself stays in focus. The cursed-house framing and the untestable allegation at its center keep it from the top tier.
