After talking with teenagers who have pulled the trigger in school shootings across the country, the U.S. Secret Service is offering advice in hopes of preventing violence from unfolding in your child's school.
That new insight was presented to school leaders and law enforcement at a seminar in Mosinee Monday.
The research says there are signs that teachers and parents should watch out for, and then take action before it's too late.
"What their research suggested is that there are very clear indicators that violence was in the offing. And if there had been some intervention earlier, it most certainly in many cases would have prevented the act of violence," said David Steingraber, an administrator with the Wisconsin Department of Justice.
Experts say it is also critical that teachers and parents keep the lines of communication open and make sure every child has an adult they can turn to.
