Bomber's motive is still a mystery despite video

In what amounts to a confession, he details weapons he built.

PFLUGERVILLE, TEXAS — 25-minute cellphone video left behind by the bomber whose deadly explosives terrorized Austin for weeks details the differences among the weap- ons he built and amounts to a confession, police said. But his motive remains a mystery.

Mark Anthony Conditt, an unemployed college dropout who bought bomb-making materials at Home Depot, recorded the video hours before he died after detonat- ing one of his own devices as SWAT teams closed in. It seemed to indicate the 23-year-old knew he was

about to be caught, said Austin Police Chief Brian Manley.

“It is the outcry of a very challenged young man talking about challenges in his own life,” Manley said of the recording, which authorities declined to release amid the ongoing investigation.

Conditt was tracked down using store surveillance video, cellphone signals and wit- ness accounts of a customer shipping packages in a disguise that included a blond wig and gloves. Police finally found him early Wednesday at a hotel in a suburb north of Austin.

Officers prepared to move in for an arrest. When the suspect’s sport utility vehicle began to drive away, they followed. Conditt ran into a ditch on the side of the road, and SWAT officers approached, banging on his window.

Within seconds, the suspect had detonated a bomb inside his vehicle, blasting the officers backward, Manley said. One officer then fired his weapon at Conditt, the chief said. The medical examiner has not finalized the cause of death, but the bomb caused “significant” injuries, he said.

Officials did not immediately say whether Conditt acted alone in the five bombings in the Texas capital and suburban San Antonio that killed two people and badly wounded four others.
