Henry Hox, 77, of Tinicum, Pennsylvania, was shot to death in his home on the 400 block of Iroquois Street and pronounced dead at the scene on September 27, 2018. He was found on the living room floor with a gunshot wound to the head.

Police say the shooting was committed by his son, 31-year-old Matthew Hox. Matthew was arrested early the next morning after an extensive manhunt and charged with first-degree murder, aggravated assault, and other related counts. Court documents state the violence followed a heated argument between Matthew and his parents over his failure to address an outstanding bench warrant for a probation violation; during the altercation Matthew allegedly shot his father and then turned the gun on his mother, Donna Hox, who was injured but survived.

Anyone who knew the family or has information about the events leading up to that night is asked to come forward.
