Authorities say Mark Anthony Conditt, the man suspected in the recent series of deadly Austin-area bombings, died in a blast that he intentionally triggered as police closed in on him Wednesday.
Questions now turn to Conditt's background and what drove his killing spree.
A friend of the suspect, Jeremiah Jensen, describes Conditt as shy, smart and thoughtful. Jensen attended church with Conditt and says he was "pretty good friends" with him in 2012 and 2013. Jensen says Conditt never exhibited tendencies that made him think he'd be "capable of something like this."
