DAYTON, Ohio (AP) — The younger brother of an Ohio pastor who was shot in a church office near the end of Sunday services has pleaded not guilty.

Daniel Schooler was arrested at St. Peter's Missionary Baptist Church in Dayton following the Feb. 28 slaying of the Rev. William Schooler.

The Dayton Daily News reports that a Montgomery County judge set Daniel Schooler's bond at $1 million on Tuesday.

The 68-year-old Schooler is charged with a count of aggravated murder and two counts each of murder, felonious assault and having weapons under disability.

A message was left Tuesday with Schooler's public defender. Records indicate Schooler has a history of mental illness.

Police say the minister's wife witnessed the last shot and that Daniel Schooler waited at the scene to be arrested.
