A father shot to death his wife and two sons and let the bodies lie in their home a few days before turning a handgun on his young daughter and himself, authorities said Friday.

Relatives and police forced their way into the locked house Thursday."It is a murder-suicide case," said Indiana State Police Sgt. Dallard Tackett. "It appears the father shot the other members of the family and then committed suicide."

Dr. William Hathaway, the DeKalb County coroner, said David M. Fager and his daughter, 11, died within 24 hours of the discovery of their bodies, while the others had been dead three or four days.
