The chilling case of a double homicide in Columbus, Ohio, has taken a shocking turn with the arrest of Michael David McKee, a 39-year-old vascular surgeon. McKee, apprehended in Rockford, Illinois, stands accused of fatally shooting his ex-wife, Monique Tepe, and her husband, Dr. Spencer Tepe, on December 30. Both victims were discovered with gunshot wounds in their suburban home.
This tragic incident has sparked discussions about the possible motives behind such a violent act. A former police chief speculated that McKee’s actions may have been driven by a “multitude” of reasons, suggesting that a recent event could have been the catalyst. The complexities of relationships and personal histories often play a significant role in such cases.
Monique and McKee shared a complicated past. Court records reveal that Monique filed for divorce in 2017, just two years after their marriage in 2015. Since their separation, McKee led a transient lifestyle, residing in multiple states including Virginia, Nevada, and Illinois. Most recently, he had settled in Chicago, Illinois, where he practiced as a vascular surgeon in the Rockford area.
Following his arrest, McKee appeared before a Rockford courtroom. He displayed little emotion as he waived his extradition rights, indicating through his attorney an intention to plead not guilty upon his return to Ohio. He faces two counts of premeditated aggravated murder in connection with the deaths of the Tepes. According to jail records, McKee was booked at the Winnebago County Sheriff’s Office shortly before noon on Saturday.
The case has captured public attention, not only for its grim circumstances but also for the questions it raises about the nature of personal grievances and their potential to escalate into tragedy. As McKee prepares to face these serious charges, the community grapples with the loss of two lives and the unsettling reminder of the potential for violence lurking behind personal entanglements.
McKee appeared emotionless when he entered the courtroom on Monday, only saying “Yes” to the judge when asked by the judge to confirm his identity.
Court documents say police identified McKee by linking him to a car that arrived in the Tepes’ neighborhood shortly before the murders and left just after the homicides. That car was located in Rockford, Illinois, and authorities found evidence linking it to McKee. While McKee worked at OSF Saint Anthony Medical Center in Rockford, he had an apartment in downtown Chicago.
Former Fort Worth Police Chief Jeffrey Halstead and Genasys spokesman told Fox News Digital there’s a “multitude of reasons” McKee may have killed Monique almost nine years after the couple got divorced. Halstead said he has worked with Columbus police in the past.

“I think what’s going to be critical for the investigators is a lot of the online search capacity, a lot, are there any recent chats? Were there any changes in the suspect’s demeanor in the last few months, last few years that could start delineating some type of frustration, revenge, outrage, jealousy, depression, anything, but usually the long-standing separation from the relationship, something had to trigger,” Halstead said.
Halstead said in similar cases he’s covered, there was financial strain or some type of jealousy issue, but said McKee’s alleged murders of Spencer and Monique goes well beyond that.

“I’ve seen these in times, in cases before, sometimes it’s relative to financial strain, financial hardship or something that the divorce was causing. This does not look like it would be the case here, but investigators are gonna have a lot of digging to find out potential motive other than just an ex-husband or jealousy,” he said.
However, Halstead said something recently had to have triggered McKee to allegedly kill the couple, and says it’s not “random.”

“I think it’s going to be a recent event that triggered the anger which started this planning. It’s not random by any means. There was something that happened, whether it’s an episode or an argument or something that motivated this person to plan this and then carry it out,” Halstead said.
The couple was killed one month short of celebrating their five-year wedding anniversary, Rob Misleh, Spencer’s brother-in-law, told WSYX.
