Chairman Jordan: What about the bombs that we've heard about in the shooter's car?
Director Wray: The FBI is exploiting those explosive devices. We've recovered three devices, two in his vehicle, and one back in his residence…these are relatively crude devices themselves, but they did have the ability to be detonated remotely…on the shooter himself, when he was killed by law enforcement, he had a transmitter with him…it looks like, because of the on/off position on the receivers, if he had tried to detonate the devices from the roof, it would not have worked.
