Who Is the Bomber Targeting Texas?

Austin remains on edge following another explosion. The urgency intensified after the fifth bomb since March 2 went off at a FedEx distribution center outside San Antonio. The package was reportedly on its way to an address 80 miles away in Austin. Like the other packages, the FedEx bomb contained nails, bolts and shrapnel. No one was injured at the FedEx distribution center. Officials say it was on an automated conveyer when it went off.
