Police pieced together store receipts, fragments of booby-trapped packages, and surveillance video allegedly showing Conditt in a hat and wig as he prepared to ship one of two suspicious packages.

We are aware because of reports, provided by citizens.>> But what they have yet to find is a reason why. Why he made a series of bombs, according to police, that killed two people, and wounded five others.
Even Conditt's 25 minute cellphone video confession failed to reveal a coherent motive.>> It is the outcry of a very challenged young man talking about challenges in his personal life that led him to this point. Federal investigators are still combing though Conditt's home trying to learn why an unemployed man from the Austin suburb of Pflugerville, wanted to terrorize the state capitol.
