Police said Williams was arrested around 6:50 p.m. Tuesday, when he was caught driving the victim’s car.

School officials said the teacher was sitting in her car in the staff parking lot around 8 a.m. Tuesday, when a male teenager walked up, claiming he was “being chased and needed help.”

Police said the teen got into the passenger side of the victim’s vehicle, pulled out a gun, and demanded the teacher’s purse, phone and car. The teacher handed over her phone and purse, and got out of the car, and the robber drove away. The teacher was not harmed.
