A Bucks County deer hunter’s death has been ruled a homicide. 52-year-old Barry Groh of Park Avenue in Quakertown was found shot to death Monday in Richland Township.  His body was in a wooded area off California Road, partially submerged in the Tohickon Creek with a dead buck next to him.  The coroner’s office says it was a homicide, which means someone else killed him, but police, Bucks County Detectives and the state game commission are investigating to determine whether it was accidental or criminal.  They have created a three-dimensional map of the area to help them find out where the shot came from.  Family members say he was an avid hunter and fisherman who was always concerned about safety.  They say he normally went hunting with his sons, 19-year-old Justin and 20-year-old Brandon, but he decided to go out alone on opening day of the firearms season.  After he shot a deer he called his wife and asked her to send one of their sons to help him drag it out of the woods, but a member of another hunting party found the body before Groh’s son arrived.  He was laid off from his job early this year when Visteon closed its Worcester plant, and he had been re-training to become an electrician.
