A 39-year-old man exposed himself as students boarded a Bulloch County school bus Thursday morning, and then undercover sheriff's investigators caught the suspect doing the same thing Friday, the sheriff's office said. On Thursday, Board of Education transportation supervisors contacted the sheriff's office "regarding incidents involving a school bus running its morning route" on U.S. Highway 80 West, Sheriff Lynn Anderson said in a news release issued Friday. The supervisors indicated that a student riding on a school bus on Highway 80 West had seen a white male driving a light gray Chevrolet Suburban pull up next to the bus - as students boarded - and expose himself.
