Police revealed that a weapon found at murder suspect Michael McKee's home matches the one that's believed to have been used to kill his ex-wife, Monique Tepe, and her dentist husband, Spencer Tepe. The weapon in question is just one of "multiple weapons" discovered by police when they searched McKee's property, Columbus Police Chief Elaine Bryant said during a news conference held on Wednesday, January 14. Bryant did not share any additional information about the weapon or where it was discovered at the property. She added that the investigation is still in the early stages, so authorities don't want to jeopardize the case prosecutors are building against McKee, 39, by sharing too much information. Authorities searched McKee's home after he was arrested on Saturday, January 10, in Rockford, Illinois. Monique, 39, and Spencer, 37, were found dead at their Columbus, Ohio, home on December 30, 2025. After one of his coworkers requested a wellness check when he didn't show up to work, police visited the couple's home and found Spencer with multiple gunshot wounds and Monique with at least one bullet in the chest. Idaho College Victims' Families Sue the University Bryan Kohberger Attended The couple's two children and their family dog were also found in the home, and they were all unharmed. McKee was named a suspect in the case after surveillance footage spotted his car near the Tepes' home. The vehicle "arrived just prior to the homicides and left shortly after," according to authorities. During the January 14 press conference, Bryant said that police have evidence that McKee was in possession of the car both before and after he allegedly murdered Monique and Spencer. After they linked the car to him, police managed to track McKee's vehicle to Illinois, and he was arrested 450 miles away from the crime scene. McKee was originally arrested on murder charges, though his charges were upgraded to aggravated murder on Sunday, January 11. He made his first appearance in court on Monday, January 12, where he stood silently as his attorney said he intends to plead not guilty. The lawyer also said that McKee was waiving his right to an extradition hearing. One day later, Spencer and Monique's brother-in-law shared insight into her brief marriage to McKee. The couple wed in 2015, and their divorce was finalized two years later in 2017. "She was terrified because he had threatened her life on multiple occasions when they were married," family member Rob Misleh said of Monique while talking to NBC News on Tuesday, January 13. Misleh went on to share that Monique's tumultuous relationship with McKee was known among family members, and he added that she "wasn't shy about talking to people about traumatic experiences that she had with her ex and just how emotionally abusive he was to her." "If any of us had known that these threats were actually grounded in possibility, we all would've acted differently," Misleh said, noting that he wasn't aware if the Mckee's abuse was physical or just emotional. Meanwhile, another family member told the Daily Mail that they "all expected" McKee to be arrested when they heard the news of Monique and Spencer's deaths.
