One theory gaining attention: Before her marriage to dentist Spencer Tepe, Monique Tepe’s life with her ex-husband was described as deeply intertwined, and some observers believe not every chapter truly closed when the marriage ended

One Theory Gaining Attention: The Lingering Shadows of Monique Tepe’s Past Marriage Before Her Life with Dentist Spencer Tepe

In the wake of the tragic double homicide that claimed the lives of Monique Tepe, 39, and her husband Spencer Tepe, 37—a respected dentist in Athens, Ohio—the investigation has taken a shocking turn with the arrest of Monique’s ex-husband, Michael David McKee, 39, a vascular surgeon based in Chicago. Charged with two counts of aggravated premeditated murder (upgraded from initial murder charges), McKee was apprehended in Illinois on January 10, 2026, after a vehicle linked to him was spotted near the couple’s Columbus home around the time of the killings on December 30, 2025. He waived extradition and faces potential life imprisonment or even the death penalty in Ohio.

The couple was discovered shot to death in their Weinland Park residence during the early morning hours, with their two young children—a 4-year-old daughter and 1-year-old son—unharmed but present in the home. Friends and colleagues raised the alarm when Spencer failed to appear for work at Athens Dental Depot, prompting a welfare check. No signs of forced entry were reported, and no weapon was recovered at the scene, adding layers of mystery to the case.

Monique’s brief but troubled first marriage to McKee has become central to public speculation. The pair wed in August 2015 and separated after just eight months in March 2016, with Monique filing for divorce in June 2017 on grounds of “incompatibility.” The divorce was finalized quickly through a private judge, with no children involved and a standard mutual restraining order issued. Court records describe the union as short-lived, with the couple living together for less than a year before parting ways.

Family members have painted a darker picture of the relationship. A brother-in-law of the Tepes told NBC News that Monique was “terrified” during the marriage, alleging emotional abuse and threats to her life from McKee. She reportedly confided that she “just had to get away from him,” describing the union as deeply distressing despite its brevity. These accounts suggest the marriage was far from amicable beneath the surface, even if official filings listed no major disputes.

Nearly a decade later—after Monique rebuilt her life, marrying Spencer in December 2020 (or around 2021 in some reports) and welcoming two children—the past resurfaced violently. One theory gaining traction among observers, true crime enthusiasts, and media commentators is that not every chapter of Monique’s life with her ex-husband truly closed when the divorce papers were signed. Speculation centers on lingering resentment, obsession, or unresolved jealousy that may have festered over the years.

Online discussions on platforms like Reddit and Instagram highlight questions about why McKee, living over eight hours away, would allegedly travel to Columbus and target the couple. Some point to possible stalking—recent neighbor reports (circulated on social media) claim McKee was seen lingering near the Tepes’ gate in the weeks leading up to the tragedy. Others theorize a “resurgence of obsessive jealousy,” triggered by seeing Monique thrive in a happy marriage and family life. True crime analysts, including retired FBI agents, suggest investigators are examining victimology, including past relationships, to uncover motive—emphasizing that severe, long-simmering grudges can erupt unexpectedly.

While the divorce appeared “amicable” on paper, the emotional toll Monique endured has fueled theories of deep-seated issues that never fully resolved. Commentators note the stark contrast: Monique moved forward with a “beautiful, strong, and deeply happy” relationship with Spencer, who was remembered by colleagues as a devoted mentor, fluent in Spanish, and passionate about comprehensive dentistry and implants. The couple shared a love of travel, laughter, and building a family rooted in joy—qualities highlighted in family statements and their 2021 wedding video.

Yet, the brevity of her first marriage (often described as “troubled” by those close to her) and the sudden violence nearly 10 years later have left many wondering if invisible threads from the past remained tangled. Investigators have not publicly confirmed a motive, but the focus on McKee’s connection has intensified scrutiny of the divorce details, including any overlooked filings or entries added to the docket in recent months (as noted in some reports from September 2025).

The Tepe family has expressed profound grief, grappling with how to explain the loss to their young daughter. A joint celebration of life was held, honoring the couple’s warmth, enthusiasm, and commitment to others. As the case proceeds, with McKee in custody and awaiting trial, this theory underscores a chilling reality: sometimes, the end of a relationship doesn’t mean the story is over.

The tragedy has sparked broader conversations about domestic abuse, long-term trauma, and the dangers of unresolved threats. For now, authorities continue their work, piecing together evidence from surveillance, vehicle tracking, and witness accounts. The answers may reveal whether the shadows of Monique’s past marriage truly refused to fade.
