Potential jurors in the trial of a father accused of murdering his stepdaughter backed out when told they would have to watch footage of him having sex with her corpse.
Prosecutors say the video confirms Gregory R Graf killed Jessica Padgett so he could have sex with her body.
Twelve jurors told the judge they felt unable to stomach the harrowing evidence and refused to serve.
Authorities claim Graf told officers on the day he was charged with murdering Ms Padgett, 33, that he wanted to sleep with her and did so after she was dead.
The 53-year-old, of Allen Township, Philadelphia, is accused of shooting Ms Padgett in the back of the head on November 21.
He is also suspected of hiding her body on his property while family and friends searched for her.
John Morganelli, Northampton County District Attorney, told the jurors: “No one wants to see this.
“This is not pleasant stuff. This is a criminal homicide case.”
He said jurors need to be able to stomach such a scene in order for justice to be served.
The trial will start Tuesday and last over a week.
Ms Padgett, of Whitehall Township, went missing the same day after leaving Duck Duck Goose Child Care in Northampton, US.
Mr Morganelli said he allowed an ‘abuse-of-corpse’ charge to be filed against Graf, but he could not pursue a death penalty because the alleged sexual abuse was committed after Ms Padgett was killed.
The district attorney claimed police discovered Graf’s cannabis-growing operation as they searched for Ms Padgett.
