After Killing Stepdaughter, Man Filmed Sex With Body: DA Sex said to be motive in gruesome Gregory Graf case By Matt Cantor, Newser User Posted Dec 8, 2014 10:31 AM CST 122 comments Comments Jessica Padgett. (Handout) (Newser) – A man who is charged in his stepdaughter's murder filmed himself having sex with her dead body, prosecutors say. That has led a Pennsylvania district attorney to what he believes was the motive in Jessica Padgett's death: He says that Gregory Graf killed Padgett so that he could have sex with her, the Morning Call reports. Now, a misdemeanor charge of abusing a corpse will be added to Graf's homicide charge, Northampton County DA John Morganelli says. The video was found on Graf's computer and made in his home, Morganelli notes; it makes "absolutely clear" that Padgett was dead at the time. Had Graf sexually assaulted Padgett before killing her, the case could have led to the death penalty; since he's accused of doing it afterward, "it's not a capital case," Morganelli says. Graf has also been charged with drug possession, the Express-Times reports, after investigators allegedly discovered he'd been growing marijuana while they were searching for Padgett.
