Authorities detain two of Mark Conditt’s roommates in Austin bombings probe

Authorities have detained two people who lived with bombing suspect Mark Conditt.

Austin police said Wednesday that one roommate was questioned and later released, while the second was still being held for questioning.

Authorities did not release the names of the roommates, explaining that they have not been placed under arrest.

Federal and state law enforcement agencies earlier Wednesday issued a news release saying a federal criminal complaint and arrest warrant were issued Tuesday night for Conditt on a charge of unlawful possession and transfer of a destructive device.

Officials say the 23-year-old Conditt blew himself up overnight in a suburban Austin parking lot as a SWAT team closed in on him. They say his motives remain unknown.
