COUDERSPORT, Pa. (AP) — A hearing has been set at which a northern Pennsylvania man is scheduled to plead guilty to murdering his ex-wife, a church organist, during a service.

A plea agreement filed by Potter County District Attorney Andy Watson says 53-year-old Gregory Eldred, of Coudersport, will plead guilty to first-degree murder and receive a mandatory life prison sentence. The Bradford Era ( ) reports that is scheduled July 10 in Common Pleas Court.

Eldred is jailed on charges he fatally shot 53-year-old Darlene Sitler, while she was serving as the organist at the First United Presbyterian Church of Coudersport on Dec. 2. The church is about 140 miles northeast of Pittsburgh.

Eldred was an elementary school music teacher, while Sitler taught music at the Northern Potter Children’s School.

Eldred’s attorney, William Hebe, didn’t immediately return a call for comment.
