"If you see something, say something," Israel said at a news conference earlier today. "If anybody has any indicator that someone's going through a behavioral change, on social media if there are disturbing photos, perhaps bombs or firearms or just videos or pictures that are just not right, please make sure law enforcement knows about it."

On Wednesday evening, a large law enforcement presence consisting of both the Broward County Sheriff's Office and Palm Beach County Sheriff's Office was spotted at the Lantana Cascade Mobile Home Park in Lake Worth. WPBF reported it may be related to the school shooting.
