PARKLAND, Fla. (AP) — Florida Gov. Rick Scott says he'll sit down with state leaders and work on how they can make sure people with mental illness aren't able to get guns.

Scott spoke Thursday a day after a shooting left 17 people dead at a high school. He said leaders will look at how they can make sure something like that never happens again.

FBI agent Rob Lasky says the FBI investigated a 2017 YouTube comment that said "I'm going to be a professional school shooter"; but the agency couldn't identify the person making the comment.

Nineteen-year-old Nikolas Cruz has been charged with 17 counts of premeditated murder in the Wednesday afternoon shooting in Parkland, Florida.
