Female DNA Found on Bomb Component

The FBI found female DNA on at least one of the two explosives used to carry out the deadly bombings, but it could have come from a woman who was in the room where the bombs were made or from a cashier at a store where some of the components were purchased, an official told the Los Angeles Times.
