“I wish I were sorry but I am not,” Mark Conditt said in the cell phone recording, according to sources familiar with his statements. He described himself as a “psychopath” and said he feels as though he has been disturbed since childhood.

Conditt also promised that he would go inside a crowded McDonald’s to blow himself up if he thought authorities were closing in on him, according to law enforcement sources briefed on the contents of the audio. The sources declined to be identified because they are not authorized to speak about the recording, which police are using as evidence in the case…

According to the sources, he began his 28-minute statement, which was recorded after 9 p.m. on Tuesday, saying “it’s me again” and blamed himself for helping investigators find him by going into a FedEx store on Brodie Lane in Sunset Valley to mail two explosive devices, one of which blew up at a transfer facility in Schertz.
