“Evidence recovered at the scene was consistent with a chemical reaction of dry ice,” said Deputy Kim Manatt.

Authorities later arrested a 16-year-old boy in connection to the crime. He was charged with deploying a destructive device causing great bodily injury.

Parent Elisa Contreras, who brought her 5-year-old son to Paramount Park, which is adjacent to the high school, said she sees how a little boy would quickly pick up a plastic bottle.

“They’re always trying to, you know, look for something to play with,” she said.
