A Montgomery County lawyer facing criminal charges in the death of a Bucks County hunter heads to court Monday, January 31, for a preliminary hearing. 49-year-old David Manilla, who has a law office on Valley Forge Road in Worcester, is charged with involuntary manslaughter and several gun and hunting law violations. Court documents say he admitted shooting 52-year-old Barry Groh of Quakertown as Groh dragged a deer along the Tohickon Creek in Richland Township on opening day of the firearms deer season, the Monday after Thanksgiving. The victim was on publicly-owned open space adjacent to a farm Manilla owned on California Road. He died almost instantly when a slug from a high-powered rifle tore through his arm and into his heart. An Affidavit of Probable Cause says Manilla did not try to help Groh after shooting him, he failed to call 911 immediately, and he tried to hide his 30-06 Remington pump-action Rifle. Manilla told investigators he knew hunting with a rifle is illegal in Bucks County, where only bows, shotguns and muzzle-loaders are allowed because of the high population density, and he admitted he was not allowed to have any firearms because he was a convicted felon.
