Whoever this person is, they are getting brave/innovative very quickly. Four bombs in just over two weeks. Starting with packages, he/she has now moved to trip wires.
The latest incident, the fourth attack in 17 days, signaled to law enforcement that the bomber or bombers have not relented in an effort to hurt or kill, leaving much of the city with an escalating sense of fear. It also demonstrated a new level of skill by the perpetrator in crafting explosives and marked an unsettling move toward apparently random attacks.
The blast, which occurred at 8:32 p.m. Sunday in the Travis Country neighborhood of Austin, injured two men in their mid-20s, Will Grote and Colton Mathis, according to Julia Thompson, who attended high school with both men and is a family friend of the Grotes’. Both were in good condition at St. David’s South Austin Medical Center, a hospital spokeswoman said.
The bomb appeared to involve an elaborate device that relied on a trip wire. Police have described the previous three incidents as “boxlike” bombs triggered by movement that were left at homes’ doorsteps.
