An elderly Bucks County man shot and killed his wife on Sunday, called 911 and then turned the gun on himself. 92-year-old Leroy Clymer and his 87-year-old wife Kathryn were found dead Sunday evening in their home on Doylestown Pike in Richland Township.  A neighbor says the Clymers were in poor health.  Leroy Clymer was a World War Two veteran, an avid outdoorsman and a founding member of the Paletown Rod and Gun Club in Quakertown.
