In the quiet hours before dawn on December 30, 2025, a horrific crime unfolded in a Columbus, Ohio home. Monique Tepe, 39, and her husband, Dr. Spencer Tepe, a well-respected dentist known for his community work and mentorship, were found shot to death on the second floor of their residence in the Weinland Park neighborhood. The couple, parents to two young children aged one and four, had no signs of forced entry, suggesting the killer was someone familiar or calculated.

Investigators quickly turned to neighborhood surveillance footage after discovering the bodies. A key piece emerged: video captured a figure in a dark hoodie and light-colored pants walking through an alley near the home between 2 a.m. and 5 a.m.—the estimated window of the attack. Tips poured in following the public release of this footage, but it was a specific customer-recorded clip that allegedly sealed the case. Medical professionals reviewing the material reportedly spotted something suspicious at precisely the 43-second mark—a fleeting detail that illuminated the suspect’s possible motive in a single, damning frame.

The breakthrough led authorities across state lines to Michael David McKee, a 39-year-old vascular surgeon based in the Chicago area, with ties to Rockford, Illinois. McKee, who had been divorced from Monique since 2017 in what appeared to be an amicable split, became the prime suspect. Surveillance from Columbus neighborhoods allegedly showed a vehicle matching one linked to him arriving just before the crime window and departing shortly after, covering over 300 miles from Illinois. That same vehicle was later located near his workplace, strengthening the trail.

McKee was arrested in Rockford on January 10, 2026, following a ten-day manhunt. He waived extradition during a brief court appearance in Winnebago County, Illinois, paving the way for transfer to Ohio to face two counts of premeditated aggravated murder. Court documents describe the killings as deliberate and targeted, with no immediate robbery motive apparent. The victims were attacked in their own home, leaving their young children nearby in distress.

The case has stunned both medical communities. Spencer Tepe was remembered as a devoted family man and professional who graduated from Ohio State and built a thriving practice. Monique had remarried in 2020 and was raising a blended family. McKee, a trained surgeon, had faced professional challenges, including evading a malpractice-related matter months earlier, but nothing publicly suggested violence.

What makes the 43-second mark so pivotal? Sources close to the investigation hint it reveals intent or a telltale sign of jealousy, resentment from the past divorce, or unresolved issues—turning a routine clip into irrefutable evidence of motive. As the case moves to Ohio courts, questions linger: Was this a long-simmering grudge erupting into tragedy? Or something more calculated? The footage, particularly that critical second, may hold the answers that bring justice to a grieving family and two devastated communities.
