Federal Authorities Have Closed Investigation Of The Austin Serial Bomber

Gabriel C. Pérez
FBI, ATF, and other state and local law enforcement, including SWAT teams, surround and investigate the address of 403 2nd Street, home of suspect Mark Anthony Conditt, in the town of Pflugerville on March 21, 2018.

Federal authorities have closed their investigation into the series of bombings across Austin last year, finding Mark Conditt had no overarching ideological motivation and acted alone.

In a Jan. 10 filing, U.S. Attorney John Bash said law enforcement closed its investigation after finding "no evidence of communications or links between Conditt and any international terror groups or domestic hate groups."

In the early hours of March 21, Conditt detonated an explosive device, killing himself in Round Rock on I-35 after a police pursuit.

Before his death, the 23-year-old claimed responsibility in a video confession for the string of bombings in February and March last year that killed two Austinites – Stephan House and Draylen Mason – and seriously injured others.

News of the investigation's closure was first reported by The Austin American-Statesman.
