ANDERSON COOPER, ANCHOR: Welcome back. There's more information, even perhaps more questions, in the case of the pizza deliveryman killed by a bomb after he robbed an Erie, Pennsylvania, bank. The FBI is expected to make public tomorrow pictures of a weapon Brian Wells was carrying. And that is not all. Mike Brooks explains.</s>MIKE BROOKS, CNN CORRESPONDENT (voice-over): For the first time the FBI has now disclosed pizza delivery man Brian Wells was carrying some type of firearm when he robbed a bank and died in a bomb blast.</s>KEN MCCABE, FBI SPECIAL AGENT: It's not what people traditionally think of as a gun.</s>ANDERSON COOPER, ANCHOR: Could it have been a knife?</s>MCCABE: No. I can say no, it's not a knife. But I'm not going to go into the specific detail of the weapon because it was unique and we want to release that maybe later in the week when we need more help from the public.</s>BROOKS: Tips began pouring in after the FBI made public photos of the locking device that held the bomb around Wells' neck.</s>MCCABE: It is not commercially made and that's why we released it, is we're hoping that somebody saw somebody making this in an industrial shop or in their home shop.</s>BROOKS: Investigators searched again at the communications tower where Wells was sent to deliver a pizza last week. Shortly after that, he robbed a bank and, when caught, told police someone had put a bomb around his neck and forced him to do it. Wells died when the bomb went off. (on camera) The FBI lab is still trying to figure out whether the handwriting on a note given to the bank teller was Wells' own writing or someone else's. They say the way the note is written is unique in places. They may release part of that to the public in the next day or so. Mike Brooks, CNN, Atlanta.
