Authorities investigating the slaying of a southwest Ohio pastor expect to charge his brother in the fatal shooting that occurred at the pastor's church office as services were winding down.

Dayton police say the Rev. William B. Schooler was shot around 12:30 p.m. Sunday at St. Peter's Missionary Baptist Church.

The 70-year-old pastor's brother was arrested at the church and taken to the Montgomery County jail. Police say they expect 68-year-old Daniel Gregory Schooler will face a murder charge Monday.

Jail records don't list an attorney for Schooler.

Police said they did not know Sunday what led to the shooting, but said the pastor was the only intended victim.

The brothers' niece, Joyce Napier, told the Dayton Daily News that Daniel Schooler has a history of mental illness.
