The employer of Michael McKee has broken its silence after the vascular surgeon was arrested for the murders of his ex-wife, Monique Tepe, and her Ohio dentist husband, Spencer Tepe. At the time of the killings, McKee, 39, worked at OSF Saint Anthony Medical Center in Rockford, Illinois. Three days after he was arrested, the organization issued a statement about their employee's arrest. "OSF is cooperating with authorities who will provide any further information," the hospital said in a statement to Us on Tuesday, January 13. The medical center added that all further questions should be directed to law enforcement. Monique, 39, and Spencer, 37, were found dead on December 30, 2025, when one of his coworkers requested a wellness check after he didn't show up to work. Police then arrived at the couple's home, where they found both Monique and Spencer dead from gunshot wounds.

Police have since confirmed that both the children and the dog were all found unharmed following the incident. McKee was arrested on Saturday, January 10, on twin murder counts. However, the charges were upgraded to two counts of aggravated murder Sunday, January 11. The accused killer appeared in court for his initial hearing on Monday, January 12, where he waived his right to an extradition hearing. On January 5, authorities released surveillance footage that showed a figure in a dark hoodie walking not far from the crime scene. At the time, police said that the individual in the footage was a "person of interest" in their investigation. McKee was formally named a suspect in the murder case after authorities saw his car near the couple's home via surveillance footage. His vehicle "arrived just prior to the homicides and left shortly after," detectives confirmed in court documents obtained by People. He was eventually arrested after authorities confirmed that McKee owned the vehicle at the time of the murders. After McKee was arrested, his neighbor Gera-Lind Kolarik admitted that she was surprised by his involvement in the murders. "He did not seem like somebody who would do something like this," she told ABC 7 Chicago. "I sat down with this man and talked with him at the pool, barbecuing, about what a beautiful day it is - and then he turns out to be [charged as] a killer. It's kind of shocking." However, the Tepe family members admitted they weren't shocked at all when McKee was arrested.

"We are all breathing a bit of a sigh of relief, because they got him." The family member also noted that neither Monique nor Spencer had not spoken about having any issues with McKee in the weeks leading up to their killings. Mckee and Monique got married in August 2015 in Columbus, Ohio, according to court documents viewed by Us. Their love story didn't last long, and their divorce was finalized in June 2017.
