A police standoff in Brownsville Texas Friday turned out to be a hoax. The two-hour ordeal started with a fake TDD-TTY device - but the two dozen officers, bomb squad unit and tactical teams who responded to the call didn't know that. All they knew is that a man had supposidly barricaded himself inside a house with hostages, automatic weapons and explosives after killing his 14-year-old sister. When police entered the home they found no one inside. The family that lived the house was gone and not aware of the call. Authorities are now looking for the prank caller.
