Police have released a video of a “person of interest” in the mysterious murders of a beloved Ohio dentist and his wife, who were gunned down last week at their home. The chilling clip, released by the Columbus Police Department on Monday, shows an individual wandering in light pants and a dark, hooded coat in a snowy alley near the Weinland Park home of Spencer Tepe, 37, and his wife, Monique, 39.
