KNOXVILLE (WATE) -- After receiving an anonymous email last fall, Knox County School officials began investigating fourth grade teacher Mark Foster. He's accused of shooting the Inskip Elementary principal and assistant principal at school Wednesday.
The email to Superintendent Dr. Jim McIntyre came from a concerned citizen, claiming to be related to Foster.
The email started with, "I don't know if you are aware of the Ticking Time Bomb named Mark Steven Foster. He is a fourth grade teacher at Inskip Elementary School."
The basis for the email was to warn school officials of Foster's behavior.
The email refers to Foster's "unpredictable violence," his "history of mental illness" and Foster being "banned from several public establishments."
It also describes him as "a very dangerous person just waiting to go off."
The email was copied to Knox County School Board members as well.
Dr. McIntyre addressed the serious allegations and the investigation that followed in a press conference Thursday afternoon.
"What was found were some family issues, some minor disputes over property lines and a few folks who really didn't like Mark Foster. What was not found was any evidence of a crime, nor any indication that Mark Foster represented an imminent threat," Dr. McIntyre said.
The superintendent also said investigators asked to meet with the anonymous emailer to discuss the allegations, but the emailer never agreed.
