"Still at large"

Catherine Herridge is reporting for Fox News that components from toy cars were used to trigger the bomb explosions in Boston.

Fox News has learned that the bulletin, sent Monday night to update local, state and federal law enforcement, is based on new forensic analysis of the bombs and reads in part, “each device likely incorporated an electric fusing system using components from remote controlled toy cars, such as a transmitter and receiver pair operating at 2.4 GigaHertz, and an electric speed controller used as a switch mechanism and sub-c rechargeable battery packs as power source."

House Homeland Security Committee Mike McCaul, who has been briefed on the bombing investigation, told Fox News the new information is further confirmation the two bombs were not made by amateurs.

“This transmitter that was used out of a toy car, that's a very sophisticated pressure cooker bomb that you don't see every day," McCaul said. "My judgment is they had training performed by either an individual or individuals who are still at large.”
