Brett Michael Davis told police he was driving his route Dec. 6 when he parked at the Russell Hall bus stop so he could walk to Brumby Hall to use the men’s room, according to a campus police report.

The 30-year-old left without his weapon to continue his bus route. A campus employee called police about 8:45 a.m. and, shortly thereafter, Davis returned — out of breath — to retrieve his gun, the report states.
