Rob Misleh/ Youtube Police are searching for the person responsible for the killings of Spencer Tepe, 37, and Monique Tepe, 39, who were found dead inside their Columbus, Ohio, apartment on Tuesday. Authorities believe the couple was murdered, CNN reports. Concern grew early Tuesday morning when Spencer Tepe failed to show up for work at Athens Dental Depot. It was an absence colleagues described to the outlet as highly unusual. Friends and coworkers attempted to reach both Spencer and his wife without success, prompting a call to 911. “I don’t know how else to say this, but we are very, very concerned,” Dr. Mark Valrose told dispatchers, “this is very out of character for him.” Colleagues later drove by the residence and reported hearing children crying inside. Around 10 a.m., a friend called 911 again after discovering a body inside the apartment. Athens Dental Depot paid tribute to Tepe in a Facebook post, calling him a devoted dentist who “will be deeply missed by our team and the many patients he cared for over the years.” Authorities have not released details about a suspect or a possible motive.
