Conditt is a native of Pflugerville, Texas, a suburb of Austin near Round Rock, where the alleged bomber killed himself.

The suspect blew himself up inside his car as police moved in to arrest him early Wednesday morning, police said.

"The suspect is deceased," Austin Police Chief Brian Manley told a news conference on Wednesday.

Manley said the suspect is believed to be responsible for all five bomb explosions that have killed two and wounded several more and put people on edge in the Texas capital since March 2. His motive was not known.

Police traced the man's car to a hotel outside Austin. As authorities waited for tactical teams to arrive, the man started to drive away.

Police moved to stop and arrest him before the man detonated a bomb inside his car and was killed, Manley said, adding that one police officer was injured by the blast.

Manley said the suspect was a 24-year-old white man and that authorities could not rule out the possibility of there being other bombs out there somewhere. He did not release the man's name.

Police zeroed in on the suspect over the past 36 hours as evidence came in from video footage and witness accounts, Manley said.

"It has been a long almost three weeks for the community of Austin," the police chief said.

President Donald Trump said in a tweet, "AUSTIN BOMBING SUSPECT IS DEAD. Great job by law enforcement and all concerned!"

As the investigation proceeded, police said the bombs were growing in sophistication.

The first three were hand-delivered to the doorsteps of people's houses. The fourth featured a trip wire, and the fifth was sent to the FedEx delivery chain.

More than 1,200 calls came in from residents since police urged them to report suspicious activities after the first explosion.

In the end, police were offering a reward of $115,000 for information leading to an arrest.
