A semi-automatic rifle and two handguns were recovered from one of the crime scenes, police said. At least 10 people were injured in the shootings at multiple locations.
Police said he chose most of the victims at random, and reportedly shot into the school but became frustrated after the teachers’ locked the doors and left after six minutes.
It is believed the school was alerted after a mother was shot at in her car while driving her children to school. She was reportedly seriously wounded but not killed.
The child who was shot has undergone surgery after being struck in the leg and chest, reports say. Other children at the school were reportedly injured by broken glass, and some were evacuated from the school and transported to hospital by helicopter.
“This individual shooter was bent on engaging and killing people at random. I have to say this incident, as tragic and as bad as it is, could have been so much worse,” Assistant Sheriff Phil Johnston said.
