Suspected Austin bomber Mark Anthony Conditt called himself a “psychopath” in an audio recording left behind on his cell phone, sources told the Austin American-Statesman. “I wish I were sorry but I am not,” he said, according to the newspaper. Conditt, 23, reportedly added that he'd been disturbed since childhood and vowed to blow himself up in a crowded McDonald's if he believed authorities were closing in on him. In the 28-minute recording, which police officials have described as a “confession,” Conditt allegedly acknowledged that he helped police identify him when he dropped off two explosive packages at a FedEx store, in view of security cameras. He reportedly also recognized that he took away people’s loved ones and caused permanent injuries by distributing the explosives. In a news conference Wednesday, Interim Police Chief Brian Manley confirmed the existence of the audio but would not give any details. Conditt blew himself up in a car off Interstate 23 on Wednesday after police closed in on him. A laptop in the vehicle was destroyed in the blast.
