PARKLAND, Fla. — Broward County deputies received at least 18 calls warning them about Nikolas Cruz from 2008 to 2017, including concerns that he "planned to shoot up the school" and other threats and acts of violence before he was accused of killing 17 people at a high school.

The warnings, made by concerned people close to Cruz, came in phone calls to the Broward County Sheriff's Office, records show. At least five callers mentioned concern over his access to weapons, according to the documents. None of those warnings led to direct intervention.
