Accused psycho surgeon Michael McKee had previously warned his ex-wife that he could kill her “at any time” before fatally shooting her and her new husband in their Ohio home, according to court records.

McKee, a vascular surgeon in Illinois, was arrested on Jan. 10 for allegedly killing his ex-wife, Monique Tepe, and Ohio dentist Spencer Tepe, in late December, as their two children and dog remained unharmed in the home.

McKee  — who was married to Monique, 39, for two years before she filed for divorce in 2017 — allegedly launched the eerie threat as part of a campaign of abuse that occurred during and after the end of their marriage, according to court documents obtained by the Columbus Dispatch.

After the Tepes’ deaths, at least one witness told investigators that Monique had described moments when McKee, 39, “forced unwanted sex,” strangled her, and threatened to “kill her at any time,” warning that he “would find her and buy the house next to hers, that she will always be his wife,” court records showed.

The documents, obtained by the outlet, also revealed that McKee was caught on video driving near Monique and Spencer Tepe’s Columbus home on Dec. 6 before walking onto the property to scope out the house.

McKee left the home “a few hours later” after sinisterly surveilling the residence while the couple was at the Big Ten Championship football game.

Monique then left the game early at halftime and Spencer told friends she “was upset about something involving her ex-husband,” prosecutors alleged.

The accused killer returned to the couple’s home — 325 miles from his own home in Rockford, Illinois — just weeks later, to gun down the Tepes in their home.

Surveillance footage captured his car near the property numerous times, including before and after the “targeted” killings, which happened around 3:50 a.m.

Court records also showed that McKee left his phone at his Rockford medical practice, which recorded no activity from Dec. 29 until after noon on Dec. 30, the outlet reported.

Police tracked the silver SUV — tied to McKee’s previous addresses — to a hospital where he worked and nabbed him nearly two weeks later on Jan. 10 at a nearby Chick-fil-A, according to the court docs.

McKee, who holds medical licenses in both Illinois and California, was extradited to Ohio and booked at the Franklin County jail to face trial.

The accused gunman was indicted on four counts of aggravated murder and one count of aggravated burglary.

He has since pleaded not guilty to the charges.

McKee faces a maximum sentence of life in prison without the possibility of parole if convicted in the double murder case.
