It's easy to pilgrim is on the scene in Saint Cloud, Minnesota good morning. And morning George this is where the attack started this entrance to the mall. A man aren't with a small knife of sorts stabbing people as he went through. Those in his path telling us this morning. It was clear. This was a man on a mission. This morning the FBI investigating if the man who went on a stabbing Rampage at a Minnesota mall had ties to terrorism that's. Eighteen year old Ryan sleep says he was walking into the mall when he came face to face with the attacker. He's started striking one in the back of the head and I was just a roadblock because I was a speed bump in his way is one hit. Now as it continued on whatever his objective was. The total nine people snapped authorities say the knife wielding attacker twenty year old to hear Don. Dressed in a security guards uniform was referring to olive during his Parikh. There was at least one. Victim who was asked if they were Muslim. After five minutes of T or an off duty police officer shooting and killing the suspect. Overnight the suspect's father speaking through a translator. He darted animal confirming his son died during the Rampage. Are you where prices sanity was a solo turn. Located within the united you can boo hoo ha new militarism and I'll ask him the local market. Saying he wasn't aware his son was involved with crisis.

Know let's have our talk about how fast this is moving a lot of clues on the ground here in new York and New Jersey oh that's exactly right I mean you that you have the luxury of a lot of surveillance cameras and you had a lot of witnesses and the combination of the two and I think they've got lucky on out on a car and a tag number. That could put together really quickly and is Ray Kelly was saying affected some of the cellphones are intact. Could yield a lot of information absolutely I think that's gonna give you a lot of clues in the east and the more important question George. Are they connected to other people and are there other bombs planted. What do you make of the sophistication of this overall attack these are. We've seen pressure cooker bombs before the Boston Marathon bombings or assume these pipe bombs that seaside. They eat you know it's one of those things it you'll like it learned this on line I think and a couple of hours in reality. We may make mistakes but that with that the bottom line is people can build bombs today because there's ready available. One of those for them in the ingredients are out there OK Brad Garrett thanks very much.
