On Jan. 6, a 6-year-old student at Richneck brought a loaded 9mm handgun to school and shot his teacher Abby Zwerner, seriously wounding her.
Diane Toscano, an attorney for Zwerner, notified school officials last month that Zwerner intends to sue the school district. Toscano said school administrators ignored warnings from several teachers in the hours before the shooting that the boy had a gun and was threatening other students. Zwerner is recovering at home.
