This classic episode of 48 Hours, which last aired on 3/6/2010, begins on July 22, 2008, when Michael Roseboro, a funeral director in Denver, Pennsylvania, called 911 to report that he had just found the body of his wife, Jan, at the bottom of their swimming pool. Less than an hour later, she was pronounced dead. An autopsy revealed that she had been strangled, beaten and then drowned. Her death was ruled a homicide and the investigation that followed pointed to Michael's personal obsession. 48 Hours correspondent Harold Dow reports.
