(Radio Iowa) – Gun safety advocates say Iowa schools need to focus on preventing gun violence after a 15-year-old was shot and killed outside East High School in Des Moines last week. Sierra Pilate is an 18-year-old senior at East High. She says schools need to offer more training for staff rather than just relying on school resource officers or police.

Pilate spoke Tuesday at a news conference organized by an East High graduate and a lawmaker who taught at the school for 40 years. Six teenagers have been charged with murder in the death of 15-year-old Jose David Lopez, whose funeral was held Tuesday afternoon.
