A man suspected of ambushing two Pennsylvania police officers responding to a domestic dispute, fatally shooting one and wounding the other, has been found dead along with a woman.
Officials have not identified the man or woman.
Police say the man died of a self-inflicted injury after shooting at the Canonsburg police officers, killing seven-year veteran Scott Bashioum early on Thursday.
The name of the wounded officer, who is in stable condition after surgery at a Pittsburgh hospital, has not been released.
Police say there's no continuing threat to the public.
Neighbours tell reporters that police were often called to fights at the home where the shooting occurred.
Police have said a woman in the home had a protection-from-abuse court order and the alleged gunman's defence attorney from an earlier incident has confirmed that information.
