The man believed to be behind a wave of bombings in Austin, Texas blew himself up on Wednesday as a SWAT team closed in on him.
Police identified the suspect as 23-year-old as Mark Anthony Conditt and tracked him down to a hotel just north of Austin.
They were following his vehicle when he pulled to the side of the road and detonated a device, killing himself.
He is believed to be responsible for five bombings since the start of the month that killed two people and injured five others in Austin and San Antonio.
His motive remains a mystery and police are scrambling to see if any more bombs remain in those areas.
