A Kentucky jury on Friday found Thomas O’Donnell, a 64-year-old Napa Valley resident, guilty of murder in the 2022 killing of Michael Harding. The conviction came after prosecutors presented a case centered on digital evidence, arguing that O'Donnell traveled across the country to carry out a calculated pay-to-kill scheme orchestrated by Harding's estranged wife, Julie Harding. The jury deliberated for barely two hours before returning the guilty verdict.
The complex plot unfolded against the backdrop of a bitter divorce between Michael and Julie Harding, a former California Highway Patrol captain. Julie Harding, identified by prosecutors as the mastermind of the scheme, never faced trial. She died by suicide in the months following her estranged husband’s death, taking her direct knowledge of the events with her. However, federal investigators were able to construct a detailed timeline almost entirely from the digital footprint she and O'Donnell left behind.
Central to the prosecution's case was cellphone data, which meticulously traced the movements of O’Donnell’s personal device alongside a second, untraceable prepaid phone. Prosecutors argued O'Donnell carried this prepaid phone specifically for the operation. Records showed the prepaid number logged three separate trips to Celina, Tennessee, where Michael Harding resided.
A crucial piece of evidence linked O'Donnell and Julie Harding directly: two days before Michael Harding's murder, O’Donnell’s personal phone registered near Julie Harding’s Sacramento residence at the same hour her own device showed her present at that location. Prosecutors told jurors this was the moment the deal was struck between the alleged co-conspirators.
On September 19, 2022, Michael Harding was lured to a vacant property on Glasgow Road in Burkesville, Kentucky, under the pretense of an HVAC repair job. He never left the location alive. The final text messages exchanged in the minutes leading up to his death were read aloud to the jury by FBI Special Agent Elizabeth Wheeler, painting a chilling picture of the victim's unwitting approach to his demise.
At 4:10 p.m., Michael Harding messaged the prepaid phone, stating he was "thirty-five minutes away." The reply was a casual, "No worries." He followed up, asking if his arrival time worked, to which the prepaid phone confirmed it did. His last message, sent just moments before his death, was three words: "See ya soon." The reply, sent at 4:16 p.m., was a single word: "Perfect." Investigators later confirmed through FBI location data that both the prepaid phone and O’Donnell’s personal device traveled in tandem throughout the entire episode, including to Celina and to the Burkesville crime scene.
Despite the compelling digital evidence, the defense highlighted gaps in the physical evidence. No firearm was recovered from the scene, the prepaid phone was never found, and a key fob connected to the case remained missing. While DNA and ammunition evidence were presented, the specific murder weapon itself never materialized. Defense attorney Sara Zeurcher argued that phone records only indicate where a device traveled, not the identity of the person holding it. She also pointed out that no financial transfer between Julie Harding and O’Donnell was ever documented.
Zeurcher suggested to the jury that a third, unnamed man might have been the actual shooter. "Julie came up with a plan involving another man and Tom," Zeurcher told the panel. "Tom was involved with this plan but did not intend for this result to happen. There has been no proof he had any idea that Michael Harding would be murdered."
Prosecutor Jesse Stockton countered the defense's arguments in his closing statement, emphasizing the weight of the circumstantial evidence. "There’s no evidence someone else killed him. All this evidence points to this amateur hitman from California. Do your duty. Find him guilty of murder," Stockton urged the jury. Their swift verdict confirmed their agreement with the prosecution's narrative.
Reports from KCRA 3 indicated that the murder unfolded as Julie and Michael Harding were navigating a contentious divorce. Colleagues of Julie Harding reportedly stated that she and O'Donnell were romantically involved. On the day Michael Harding was shot dead in Kentucky, Julie Harding's phone records showed she remained in Sacramento.
O'Donnell is scheduled to appear for sentencing on Monday, where he faces a minimum of 20 years and a maximum of life behind bars for his role in the murder.
