OXFORD, Mass. (AP) — A man who had recently separated from his wife shot his two children, killing his 7-year-old daughter, before committing suicide, prosecutors said.

A family member called police Saturday night after finding the bodies of 41-year-old Daryl Benway and his daughter, Abigail, in the master bedroom of their two-story Oxford home, Worcester County District Attorney Joseph Early Jr. said. Benway’s 9-year-old son, Owen, was found shot in the head in the kitchen and was taken to UMass Memorial Children’s Medical Center in serious condition.

Benway’s wife, Kelleen, returned home after the shootings, unaware of what had happened, and found a swarm of police cruisers and television crews, Early said. She was taken to the children’s hospital, where authorities told her the fates of her children and husband.
