TAMPA, FL – A former FBI agent says more mass murders may be prevented if people listen to and dissect concerning statements.

“Unfortunately, in America right now we’re averaging somewhere between 16-20 mass murders a year. That’s a little bit over one a month and that’s a real tragedy,” Tampa resident and former FBI agent Joe Navarro said.

Navarro spent 25 years as an FBI agent and has taken a look at the Charleston church shooter, Dylann Roof. Navarro said Roof matches the profile of a mass shooter.

“Individuals like this have a pattern of what we call wound collecting, that is that they look for grievances. They look for things they don’t like. They look for things that irk them, bother them and they collect these things, whether it happens to them or to other people,” Navarro said.

“The question is are we listening to it and are we dissecting what they’re saying and realizing this individual has gone from disliking something, to disliking something and he wants to take care of it with violence,” he said about preventing mass murders.

“He could’ve popped up on the FBI’s radar if people were listening to him and saying, ‘Look this is an individual that you need to pay attention to,’” Navarro added.
