Is this who i need to stop . Reporter suspect reported hal a troubled past and was expelled from the school. And the leader of a White Nationalist militia florida says cruz was member his group who participated in military drills. But he had no criminal record and wasnt on police or fbi radar. Even though students at the school describe him as troubled and prone to violence. Many of those students now meeting with drama counselors as they start to come to terms with what they witness. It was more shock than anything. We thought it was drill but we started seeing the headlines people started freaking out. I feel like name a dream. Theres no way to describe what happened.

Here at home police say theyre constantly monitoring social media. Our Dave Schratwieser joins us live from Philadelphia Police headquarters. Dave . Reporter lucy, the fbi confirmed today that it did check out a tip about nikolas cruz last september from a youtube blogger in mississippi. After checking it out, its unclear what happened next. Philadelphia police on the other hand say that they check out every School Threat immediately. What triggered this kid . What were the triggers. As the mass shooting in parkland, florida, unfolded wednesday, and the alleged killer nikolas cruz was taken into custody fbi agents began tracking his every move leading up to the shooting. Including a tip they got five months earlier from youtube blogger ben, who sent the fbi a screen shot from a nikolas cruz posting. This comment said, im going to be a professional School Shooter and i knew that i couldnt just ignore that. Reporter fbi now confirms it did investigate the tip. No other information was included with that comment. Which would indicate a time, location or the true identity of the person who made the comment. The fbi is only as good as the information it either receives or it can obtain through legal means. Reporter former fbi special agent john terry who worked in philadelphia told fox 29 a typical fbi investigation would entail database reviews and other checks to determine who posted it. Start looking into this persons background. Is this someone whos got other data points or dots that we should be connecting. A loft times theyre just someone mouthing off on social media but we take it real serious. We have investigators go right out and run of these. Philadelphia police get lots of tips and monitor social media for threats against schools. Any hint of any kind of anything thats off, we immediately investigate that. Reporter Deputy Wilson says if a threat is real and a lock down occurs, like the one at Lincoln High School just last month, no resources are spared. All hands on deck when we get a threat. We want to intercept it immediately. Reporter john terry says connecting all the dots in a threat investigation can be complicated and time consuming. Investigations like putting a puzzle together. You grab different pieces of the puzzle and you try and paint a picture that anyone can understand.

Theyve investigated numerous threats and in some cases have stopped threats in their tracks before anything happened. Lucy . All right, thank you much dave.

Ironically getting the final approval for the club the day before the bloodshed in florida. Im sad that i actually have to start this club parkland is just another reason for to us raise awareness and its very sad. Report roar this school like many across the area has security measures in place to keep students safe. Holding regular drills about what to do in the case of an active shooter. Still some worry about what they would actually do in a real life and death situation. I always say my exit route. The windows i could where i could possibly hide. I thought about it. Its just more scary. Like you can always be trapped and how you would get out and what about your friends and stuff, too . Is anyplace safe any more . Like i mean really.
