The Austin bomber's confession video is the "outcry of a very challenged young man"

Austin bombing suspect Mark Anthony Conditt would have continued his murderous spree had police not tracked him down, according to a video confession found on his phone.

Conditt, 23, was killed when he set off an explosive in his car in Round Rock, north of Austin Wednesday as SWAT team members closed in.

Conditt terrorized the residents of Austin for almost three weeks with a series of parcel bombs that killed two and injured seven more — yet his motive remains a mystery.

The 25-minute video was found on the suspect’s cell phone, which was in his possession when he blew himself up, police said.

“I would classify this as a confession,” interim Austin Police chief Brian Manley said at a press conference Wednesday.

In the video Conditt describes how he constructed all seven explosive devices in detail, the last of which he used to commit suicide.

“I know everybody is interested in a motive and understanding why, [but] we're never going to be able to put a rationale behind these acts,” Manley said. “Having listened to that recording, he does not at all mention anything about terrorism, nor does he mention anything about hate.”

“Instead, it is the outcry of a very challenged young man talking about challenges in his life that led him to this point," the interim chief added.

Conditt lived in a house he owned in Pflugerville, 17 miles from the city he terrorized. He shared the property with two roommates. Police found bomb-making equipment in his room and interviewed both of his roommates, neither of whom were arrested.

The family of Conditt issued a statement to CNN Wednesday, saying it was “devastated and broken” by the news.

“We had no idea of the darkness that Mark must have been in,” the statement said. “Our family is a normal family in every way. We love, we pray, and we try to inspire and serve others. Right now our prayers are for those families that have lost loved ones, for those impacted in any way, and for the soul of our Mark. We are grieving and we are in shock.”
