"Let's figure out how we get these kids in school, get them the education they need and set them up to be successful. Not set them up for jail or a life of crime. And so that's where we're going to continue to focus. We have gun laws. We have laws on the books right now for guns, and those weren't accessed legally," Reynolds said.

Des Moines police haven't determined how the teens got the guns, but say they were possessed illegally because they were minors.

Fifteen-year-old Jose Lopez was killed in the shooting on March 7.
