A North Georgia social studies teacher, known as the longtime “radio voice” of Dalton High School football and basketball, is facing charges after he fired at least one shot inside a classroom Wednesday, and he once tried to confess to having someone killed, police said.

The alleged confession was one of two previous incidents involving Randal Davidson and local police.

Dalton police could not verify any of the information Davidson said on March 21, 2016, about having two friends kill someone on his behalf. Police ultimately took him to Hamilton Medical Center because he was having suicidal thoughts, according to a police report. The school was made aware of the incident, police said.

Then, in January 2017, Davidson disappeared from the high school campus after saying he didn’t feel well and leaving early. He was found hours later sitting on a curb about a mile away, unable or unwilling to respond to police, according to the report. He was again taken to the hospital and no further action was taken by officers.
