Police: Man captured after fatally stabbing girlfriend's 8-year-old son

Police in western Pennsylvania say a man who was on parole for a previous homicide stabbed his girlfriend's 8-year-old son to death during a domestic dispute.

Keith Burley was apprehended Tuesday by U.S. Marshals in Youngstown, Ohio. Authorities say he didn't put up a struggle, and it wasn't known if he's retained a lawyer.

Pennsylvania state police say the 43-year-old killed the boy around 10:30 p.m. Monday at a house in New Castle. The boy's 7-year-old sibling ran over to a neighboring home for help.

Authorities say Burley's 36-year-old girlfriend and the children were in a vehicle with him when she got out of the car to call for help. Burley then drove away with her children still inside and went to a friend's house, where the stabbing occurred.
