The Texas serial bombing suspect is dead according to US police.
Austin Police chief Brian Manley confirmed the death of the 24-year-old man, who has not been named, after officers tracked him down to a hotel in Round Rock, near Austin.
The suspect set off the explosive device inside his vehicle as a SWAT team approached.
One of the SWAT officers also shot at the vehicle and an officer was injured in the explosion.
Police traced the man using a mix of cell phone technology, CCTV footage of one of the previous attacks and store receipts.
He was identified in the last 24 hours after shipping an explosive device from a FedEx store in the Texas capital, the Austin Statesman said.
Authorities found store receipts showing suspicious transactions and obtained a search warrant for his Google search history which also showed suspicious behaviour, an official told the newspaper.
Police then used mobile phone technology to trace the suspect to a hotel in Williamson County and a chase ensued, according to reports.
Two me were killed in the string of bombings in Austin over the past two weeks – Anthony Stephan House, 39, and Draylen Mason, 17.
Four others were injured.
US president Donald Trump branded the person behind the attacks a "very sick individual."
