Investigators said the Austin bombing suspect recorded "a confession" on his phone before he died.
Officials found the phone on the suspect's body after he killed himself by detonating a bomb inside his vehicle early Wednesday.
In the recording, the 23-year-old suspect reportedly described each bomb he'd constructed and how they differed.
"He does not at all mention anything about terrorism, nor does he mention anything about hate. But instead, it is an outcry of a very challenged young man talking about the challenges in his personal life," Austin Police Chief Brian Manley said Wednesday.
Police say he built and delivered six bombs in Texas that killed two people and injured five others.
The suspect reportedly did not say if he created the explosive devices to target any specific people.
