Prosecutors say necrophilia motivated a Pennsylvania man to fatally shoot his stepdaughter last month.
Gregory Graf was charged after police found 33-year-old Jessica Padgett's body buried on his property in Northampton County.
District Attorney John Morganelli said Friday that Graf videotaped himself sexually abusing the body. Authorities say they found the video on Graf's computer on Thursday.
Morganelli says the 53-year-old fencing company owner confessed to killing Padgett, a mother who worked at a day care. Padgett's mother was in Florida at the time of the slaying.
Graf is being held without bail on a homicide charge. Morganelli says he will also be charged with abuse of a corpse.
Graf doesn't have a lawyer.
