When Dr. Spencer Tepe doesn't show up for work at Athens Dental Depot in Columbus, Ohio, coworkers are shocked. They call their boss, the owner of Athens Dental, Dr Mark Valrose.
Valrose is on vacation in Florida, but Spencer not showing up is so unusual that coworkers felt they needed to let Valrose know. Valrose tries to contact Spencer, and failing at that, Tepe's wife, Monique, is even more predictable than her husband.
Unable to reach either Tepe, Valrose calls 911 in Columbus, Ohio, at 9:03 a.m., requesting a wellness check. Their bodies are found inside their house, which is now for sale.
Early reports indicated Monique was shot once in the chest, and Spencer was shot more than once, with three shell casings found at the scene.
In fact, the killer unloaded a full clip, 16 rounds, and both were shot in the head: Monique in her right cheek, and Spencer in his left ear. A total of 16 gunshot wounds are discovered. A standard magazine for a handgun holds 15 to 17 rounds, depending on the size of the bullet.
Spencer and Monique likely died within "seconds to minutes" of being shot. The injuries suffered and the trajectories of bullets indicate some movement by Spencer and Monique; the range of fire is indeterminate, and there is no way to tell in which order the injuries are inflicted.
Michael McKee, 39, arrested in the murders of his ex-wife and her new husband, is being held without bond in the Franklin County Jail. He pleaded not guilty to four counts of aggravated murder and one count of aggravated burglary.
According to a newly unsealed affidavit, witnesses claimed McKee was abusive during his marriage to Monique and had threatened to kill her. Court documents indicate McKee had previously visited the couple's home on Dec. 6, 2025, while they were away.
McKee, a vascular surgeon from Illinois, drove 900 miles to commit the murders. He was tracked through surveillance video, which showed a silver SUV. Police also reportedly found multiple weapons in his Chicago-area condo, with one being connected to the crime scene.
McKee faces a minimum of life in prison with parole eligibility after 32 years if convicted.
