An investigation is underway to gather as much information as possible after a package blew up at a FedEx facility outside of San Antonio early Tuesday morning, March 20. One person is reported to have suffered a non-life threatening injury in the blast - which officials believe to be linked to a series of Texas attacks orchestrated by a package bomber over the past month.

According to reports, the explosion was set off at the FedEx ground distribution center in the city of Schertz at around 12:30 a.m. Evidence recovered from the scene indicates that the device that detonated was sealed in a medium-sized package containing nails and other shrapnel.

Prior to its destruction on one of the facility's conveyor belts, the delivery was set for the Austin area, although details on what persons might have been targeted have not been made available to the press.

Workers at the 9935 Doerr Lane location were prevented from leaving until authorities could determine them clear of any suspicion of involvement. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives have since taken the probe over from local police. Two people are dead and four have now been injured in what is suspected to have been five related explosive attacks since March 2.
