QUAKERTOWN, Pa. An eastern Pennsylvania prosecutor says a man apparently tried to commit suicide by leaving a car running in a garage and the carbon monoxide fumes apparently claimed not only his life but those of his wife and their two children.

Bucks County District Attorney David Heckler said Tuesday night that a state police investigation indicates that Gary Reitnauer went to the garage of an adjacent home on the family's Milford Township property and started the car in an apparent suicide attempt after some kind of disagreement with his wife, Michelle.

Heckler says she then apparently broke a window to get into the garage but was overcome by carbon monoxide fumes. He says their 16-year-old daughter Kimberly later went to the adjacent kitchen but was overcome. Ten-year-old daughter Jamie is believed to have done the same and was barely alive when rescuers arrived. She later died.

Police were called to the home in Milford Township, Bucks County, at 11:20 p.m. Monday, and found it filled with carbon monoxide.
