THE NATION IS SH:O:CKED BY THE DENTIST COUPLE CASE: A major mistake led to Michael McKee’s arrest in the m:u:rd:er of his ex-lover Monique Tepe and her dentist husband, One detail at the crime scene revealed everything

The alleged killer surgeon who has been charged in the murders of Ohio dentist Spencer Tepe and his wife, Monique, was identified after police tracked his vehicle through neighborhood surveillance close to the couple’s home, according to court documents.

Michael David McKee, 39, a doctor from Chicago, was arrested in the execution killing of his ex-wife Monique, 39, and her second husband, Spencer, 37, in the upscale Columbus, Ohio neighborhood of Weinland Park.

In the end, it was McKee’s car that put him at the scene of the crime through his vehicle, which was seen 325 miles from his home — near the murder scene on Dec. 30, the night of killings, according to court documents obtained by PEOPLE.

McKee’s car “arrived just prior to the homicides and left shortly after,” detectives noted in the court documents, adding that the vehicle was later found near his workplace in Rockford, Ill.

Evidence showing McKee owned the car was uncovered by detectives, leading them to suspect Monique’s ex, according to the court documents.

McKee and Tepe were married from 2015 until she filed for divorce in 2017, according to the Columbus Dispatch.

He was living in Virginia at the time the divorce, believed to be amicable, was finalized, the outlet reported.

The couple had no children together.

No motive has yet been given for the shooting by police.

McKee was arrested on Saturday and charged with two counts of murder, hours after a warrant was issued for his arrest, court documents state.

The Tepes were found slaughtered after one of Spencer’s colleagues became worried when he didn’t show up for work, and performed a wellness check, following three hours of trying and failing to reach him.

Another of the couple’s friends told 911 dispatchers he could hear their children, ages 1 and 4, crying inside the home when he also checked in on the family.

Officers arrived and found the Tepes dead from gunshot wounds at the scene, although there were no signs of forced entry, the Columbus Division of Police said.

Almost a week later, surveillance footage of a mysterious hooded figure walking down an alleyway close to the couple’s home around the time of their deaths was released by Columbus Police.

It is unclear if the person in the video is McKee.
