In a startling development that has deepened the chilling narrative surrounding the December 30, 2025, double murder of Columbus dentist Spencer Tepe and his wife Monique Tepe, investigators have reportedly uncovered evidence of obsessive behavior linked to the suspect, Michael David McKee. Specifically, digital forensics revealed that an alternate or secondary social media account belonging to McKee had repeatedly accessed and viewed videos and posts commemorating the couple’s wedding anniversary and their joyful married life—content that highlighted Monique’s happiness with her new husband, Spencer.

The revelation emerged as part of the broader investigation into McKee, Monique’s ex-husband, who was arrested on January 10, 2026, in Rockford, Illinois, and now faces two counts of aggravated murder with premeditation. Authorities believe this pattern of surveillance on the couple’s personal milestones points to a deep-seated fixation on his former wife, compounded by jealousy over her fulfilling new life, which may have driven the alleged premeditated attack.

Spencer Tepe, 37, and Monique Tepe, 39, were found shot to death in their Weinland Park home on the 1400 block of North 4th Street. Their two young children, ages 1 and 4, were unharmed, and there were no signs of forced entry, suggesting the killer was someone familiar or trusted. The couple had celebrated their fifth wedding anniversary just weeks earlier, in late December 2025—a milestone that was publicly shared through photos, videos, and heartfelt posts on social media platforms. These included clips from their January 2021 wedding ceremony in Columbus, vows exchanged amid smiles and tears, and anniversary tributes emphasizing their deep love, family life, and overcoming past challenges.

Monique’s vows from that day, which referenced moving past “wrong relationships” and a “waterfall of tears,” have been interpreted by some as subtle allusions to her brief, difficult marriage to McKee. The couple met online, built a blended family, and were described by friends as soulmates who radiated joy. Spencer, a dedicated dentist specializing in implant therapy and fluent in Spanish, was known for his compassion, while Monique, a former childhood education professional turned stay-at-home mom, loved baking, soccer, running, horses, and reading.

McKee, 39, a vascular surgeon practicing in the Chicago area (with prior licenses in California and elsewhere), had married Monique in August 2015 under her maiden name Sabaturski. Their union lasted roughly two years, ending in divorce in 2017 amid reports of emotional abuse, according to family statements. No children were involved, and the split was finalized privately, with Monique covering certain fees to expedite the process. Nearly a decade later, the killings occurred just as the Tepes approached what would have been their fifth anniversary milestone.

Investigators, combing through digital trails as part of the motive analysis, traced anomalous activity on platforms where the Tepe couple had shared wedding and anniversary content. An alternate account—linked to McKee through IP addresses, device information, login patterns, and other metadata—was found to have repeatedly revisited these materials in the months leading up to the crime. The views were frequent and focused, often on videos showing Monique smiling beside Spencer, surrounded by their children, or celebrating family moments that starkly contrasted with McKee’s own past with her.

This discovery has bolstered theories of obsession and envy. Former FBI agents and behavioral experts consulted in media discussions have suggested that McKee may have harbored unresolved resentment, watching from afar as Monique thrived in a loving marriage. The repeated engagement with anniversary content—symbolizing the life she built without him—could indicate escalating fixation, where perceived rejection fueled jealousy into something more dangerous. Such patterns are not uncommon in cases involving ex-partners, where social media serves as a window into the “what could have been,” amplifying bitterness over time.

The digital evidence complements physical clues that led to McKee’s arrest. Surveillance footage released by Columbus police showed a hooded figure in an alley near the home between 2 a.m. and 5 a.m., the estimated time of the shootings. The figure’s path was tracked to a vehicle that arrived shortly before and departed soon after. That car, a white model registered to McKee, was later located in Rockford, placing him in possession before and after the incident. No forced entry, three 9mm shell casings, and the sparing of the children all pointed to a targeted, personal vendetta.

McKee’s professional life appeared stable on the surface—he was a respected surgeon with no prior criminal record—but colleagues later described him venting about feeling “disrespected” and hinting at retribution in the month prior. Neighbors in Chicago’s Lincoln Park saw him as unassuming, unaware of any turmoil.

Following his arrest, McKee waived extradition in an Illinois court appearance, appearing composed in a yellow jail jumpsuit. He has indicated plans to plead not guilty. The Tepe family expressed relief at the arrest as “an important step toward justice,” while stressing their focus on the children and honoring the couple’s legacy of love.

This latest digital revelation paints a picture of a man allegedly unable to let go, consumed by watching the happiness he no longer shared. In an era where social media keeps past relationships in constant view, it serves as a tragic reminder of how lingering obsessions can turn deadly. As the case moves toward trial in Franklin County, Ohio, the evidence—from surveillance to shell casings to online footprints—continues to build a compelling narrative of premeditated revenge rooted in jealousy and unresolved pain.
