The Navy says that a petty officer shot in Thursday's attack has died. Officials haven't formally identified him, but his identity has been confirmed as Petty Officer 2nd Class Randall Smith.

A spokeswoman for First Energy says he was dismissed for "not meeting minimum requirements for employment." Mohammod Youssuf Abdulazeez attacked two military centers Thursday and killed four Marines.

The word terrorism is a tricky one. That's because, as one linguist says, "terrorism itself, whatever that is" lives in a place between crime and war.

Mohammod Youssuf Abdulazeez, whom authorities have signaled as the man who shot and killed four Marines, is described by friends as funny, charming and devout.
