Austin bomb suspect described himself as a 'psychopath' in confession

Hundreds of investigators continue to search for the reason why a 23-year-old Austin man went on a deadly bombing spree. 

Mark Conditt left a recorded twenty-five minute long confession on his cell phone, though it has yielded more questions than answers. 

Investigators say Conditt called himself a "psychopath" and said he felt no remorse for the explosions that killed two people and terrorized the Austin metro area.

Authorities say Conditt makes no mention of a racial motivation, but investigators are still looking into that as a possibility. The first three victims were minorities.

At a news conference Saturday, Congressman Michael McCaul, a former federal prosecutor who chairs the House Committee on Homeland Security expressed gratitude toward law enforcement for bringing the three-week spree to an end.

He called the investigation a textbook example of how local, state and federal agencies should work together.
