Fifth Package Explosion in Texas

Fear grips Texas after reports of another package explosion as investigators scramble to find a “serial bomber.”

The latest blast happened early Tuesday inside a FedEx facility in Schertz, about an hour southwest of Austin.

The package was filled with nails and metal shrapnel, according to the San Antonio fire department.

Investigators suspect this incident is connected to the four other explosions which killed two and injured four others.

This comes on the heels of another detonation Sunday evening in an Austin neighborhood.

Police say a tripwire set off that explosive device which injured two young men.

A reward for information now stands at $115,000.
