The mayor of the suspected Austin bomber's hometown says the suspect lived only two blocks away from him in a part of the city known as Old Town.
Pflugerville Mayor Victor Gonzales told The Associated Press on Wednesday that police had surveillance on the home overnight Tuesday, though he said he didn't personally know the family.
Gonzales says he had concerned neighbors approaching him because of the large police presence in the neighborhood. He says he let them know everything would be OK.
Authorities say the suspect blew himself up overnight in his vehicle in a hotel parking lot in another suburb as a SWAT team closed in on him.
A law enforcement official has told the AP that the suspect was Mark Anthony Conditt. The official, who has been briefed on the investigation, spoke on the condition of anonymity because the official wasn't authorized to discuss the case publicly.
Investigators believe Conditt made all of the bombs used in the four Austin attacks, which killed two people and injured four others.

Reporters have converged on a neighborhood in an Austin suburb where the bomber who died overnight lived.
Police have blocked off the roads around Wilbarger and Second streets in Pflugerville, which is just north of Austin and not far from where a package bomb killed a 39-year-old man on March 2.
Pflugerville Mayor Victor Gonzales told The Associated Press that the bomber lived in his city, two blocks from his house.
Jay Schulze, who has lived in the Pflugerville neighborhood for 13 years, says he was out jogging last night when he was stopped by police and asked about the bombings. He says there has been a large police presence in the neighborhood since last night and that that police flew drones over a home from about 9 p.m. until about 3 a.m.
He described the home over which the drones were flying as "a weird house with a lot of people coming and going" and a bit rundown.
Authorities have not released the dead suspect's name, describing him only as a 24-year-old white man.

A federal agent says it's "hard to say" whether the dead suspect in this month's Austin bombings was acting alone.
Fred Milanowski, agent in charge of the Bureau of Alcohol, Tobacco and Firearms' Houston Field Division, told reporters Wednesday that investigators believe the dead suspect built all of four of the package bombs that have blown up in Austin since March 2.
Authorities say the 24-year-old suspect blew himself up in his vehicle overnight as a SWAT team closed in on him in a suburban Austin hotel parking lot.
Milanowski says investigators aren't completely convinced that there aren't other explosive devices "out there," and that they want the public to remain vigilant.
He called the bomb that killed the suspect "a significant explosive device."
Asked if the suspect built bombs prior to the start of the spree in Austin, Milanowski responded: "We know when he bought some of the components. It's hard to say whether he was building along the way"
