Austin, Texas has its Fourth Bombing

The city of Austin, Texas, was rocked by another bombing, the fourth this month. The explosives went off in a residential neighborhood, Sunday night, leaving two people in the hospital with non-life threatening injuries.

In an interview with “Good Morning America,” Austin Police Chief Brian Manley said that both men injured in Sunday night’s explosion were white, but victims in the three earlier attacks were black or Hispanic.

Police believe the latest attack may be related to the three bombs that detonated earlier. Many residents are frightened. Authorities have ordered those in the area to shelter in place, with doors locked while investigators try to capture a suspect.

The Police Chief says that this bombing was caused by a tripwire and showed “a different level of skill” than the package bombs used in the previous attacks. Authorities have yet to explain who could be setting off these devices or why, saying only that the bombs were sophisticated and could have been motivated by racial bias. They acknowledged the racial angle is just a theory.

Last week authorities urged residents receiving unexpected packages to call authorities before touching or opening them. Since then police have responded to hundreds of calls about suspicious packages but didn’t find anything dangerous.
