Bucks County District Attorney David Heckler alleged Lloyd Hill waited for Tarantino, 43, outside the apartment and then beat him to death with a baseball bat shortly after 5 a.m. Friday. He then allegedly stabbed Stephanie Hill, 36, inside the apartment, the prosecutor said.

Terry Pursell Jr., who lives in the complex where the killings took place, said he found Frederick Tarantino's body as he returned from feeding his horses and then heard the Hills' daughter screaming that her mother had been stabbed.
"She was starting to groan and trying to talk, I thought she had a chance," said Pursell, who told the Call Stephanie Hill was still breathing when paramedics arrived.
