Police believe a man shot to death in the St. Clair County Courthouse Monday afternoon took his own life.
St. Clair County Sheriff Richard Watson says it happened on the fourth floor of the parking garage about 4:30 p.m.
Police haven't released the man's name pending notification of family, but say he was 25-30 years old and had addresses in both Belleville and Caseyville, Illinois.
Watson says the man had not gone to the courthouse but to the probation office on the other side of the garage.
Sheriff's deputies and Belleville police had initially closed down the garage thinking there might be a gunman still lurking. It reopened about an hour later.
