Nearly a week after an Ohio dentist and his wife were shot to death inside their home, police have released footage of a person of interest, according to authorities. A video shared to Facebook on Monday, January 5 by the Columbus Division of Police shows a person walking in an alley near the Columbus home of Spencer and Monique Tepe between 2:00 and 5:00 a.m. on December 30, the agency said. In that span of time, detectives suspect the couple was killed "in the upstairs of their residence," according to police.
