(CNN) — The man accused of killing his ex-wife and her new husband in their Columbus, Ohio, home allegedly had a history of abusing her and stalked the house weeks before their deaths, according to a newly unsealed court document.
Monique Tepe told her friends and family her ex-husband Michael McKee was abusive and threatened to kill her during and after their brief marriage of less than two years, a probable cause affidavit written by a Columbus detective says.
One witness told police Monique had shared that McKee “forced unwanted sex” upon and strangled her, according to the affidavit. Another person told police McKee “had told Monique that he could kill her at any time and would find her and buy the house right next to her, that she will always be his wife,” the document says.
Monique and Spencer Tepe were found dead inside their house on the morning of December 30, 2025. Their children, aged 1 and 4, were also inside but unharmed. For weeks after the killings, police were tight-lipped about the investigation and any possible motive, with the Columbus police chief saying only that the attack was “domestic violence-related.”
Now the unsealed affidavit is painting a picture of McKee’s alleged movements around the Tepes’ home before and after the killings, tracking his presence in the neighborhood – and shedding new light on the search for the suspect.
A Franklin County grand jury has charged McKee with aggravated murder and aggravated burglary while using a firearm suppressor, according to the indictment. He has pleaded not guilty.
Diane Menashe, a defense attorney for McKee, declined to comment on the allegations in the affidavit when reached by CNN. She waived a request for bond at McKee’s arraignment in Ohio on January 23.
Footage placed suspect at scene before killings, document says
Monique Tepe and McKee married in August 2015. Their divorce was finalized less than two years later – in June 2017, court records show – about a month after it was filed by Tepe, who was using her maiden name of Sabaturski at the time.
On December 6, 2025, detectives uncovered surveillance video of McKee near the Tepes’ house while the couple was out of town at the Big Ten Championship football game in Indiana.
The affidavit says McKee was seen on the “curtilage” of the property, a legal term used to describe the area immediately surrounding a home, including things like the yard or driveway. McKee left a few hours later, it says.
McKee, a vascular surgeon who was living in Chicago, was not on the schedule that day at OSF Saint Anthony Medical Center, where he worked, according to the document.
Monique Tepe left the football game in Indiana early, her friends told investigators. When they asked her husband why, Spencer told them, “She was upset about something involving her ex-husband and was going back to the hotel,” according to the affidavit.
Police also used surveillance video to track a suspect to a car the affidavit says arrived in the Tepes’ neighborhood shortly before the killings on December 30 and left shortly after. During the investigation, police released footage showing “a person of interest” walking in the alley near the couple’s home in the Weinland Park neighborhood and later said they believed the person was McKee.
The Tepes were killed sometime between 2 a.m. and 5 a.m., Columbus police have said.
