PITTSBURGH — An elementary school music teacher shot his former wife while she played the organ during a Sunday church service, then returned minutes later to shoot her again and ensure she was dead before congregants stopped and grabbed him, police said.

The shooting was detailed in a criminal complaint filed Monday against Gregory Eldred, 52, of Coudersport, who remained jailed without bond on first-degree murder and other charges in the shooting at the First United Presbyterian Church of Coudersport.
