(AP) — Authorities in eastern Pennsylvania say an elderly couple found dead at a resort in the Pocono mountains had been beaten and stabbed to death. Officials said a suspect killed himself after a police chase.

Carbon County Coroner Bruce Nalesnik ruled the deaths of 77-year-old John Carnochan and 75-year-old Mildred Carnochan homicides, saying they died of blunt force trauma and stab wounds to the head and chest.

Hours after their bodies were found Saturday afternoon at the Split Rock Resort, police in neighboring Northumberland County were checking a Snydertown home for their missing car when they spotted it and gave chase. They said 30-year-old Greg Demage of Jim Thorpe shot himself after the car was stopped. State police at Fern Ridge say he is the only person suspected in the homicides.
