William Schooler, a 70-year-old pastor at St. Peter’s Missionary Baptist Church in Dayton, Ohio, was shot and killed at the end of a church service on February 28, 2016. The shooting occurred as the choir was singing; witnesses heard two shots and worshippers fled. William was pronounced dead at the scene.

The suspect was his younger brother, Daniel Schooler, then 69, who was reportedly sitting in the pews and followed William toward the back of the church before the shots. Daniel was taken into custody shortly after the shooting. Reports said the motive was not immediately clear, though some accounts suggested a domestic situation and noted Daniel’s history of mental illness and violence.

The killing devastated the congregation and wider community; William was remembered as a dedicated leader. Does anyone who attended St. Peter’s that day or knew the family have information that could shed light on what led to the shooting?
