Federal investigators have been combing through Mark Anthony Conditt's home in Pflugerville, where they discovered bomb-making materials, for about 12 hours. 

Authorities came up with evidence that allegedly ties Conditt to the attacks.

Neighbors within five blocks of every direction were forced to evacuate as a precaution. All evacuees were permitted to go back home Wednesday night.

The Red Cross stayed in the area for hours, handing out food to those who needed it. Volunteers say they will return Thursday if they are needed. 

6:17 p.m.:

Austin Police Chief Brian Manley said a 25-minute recording made by serial bombing suspect Mark Anthony Conditt was found, and he classified it as a confession.

During a news conference, Manley said the recording didn't mention terrorism or hate but called it "an outcry of a very challenged young man in his personal life."

Manley said that Conditt described the seven bombs that he made, including the one that blew himself up early Wednesday.

4:30 p.m.

An official with the Bureau of Alcohol, Tobacco, Firearms and Explosives says the agency is reasonably certain there are no other devices "out in the public," but he urges caution.

ATF Special Agent in Charge Fred Milanowski made the comments at a Wednesday afternoon news conference. FBI agent Chris Combs echoed Milanowski's sentiment, saying "we think we're on top of this, but we just don't know."

On Twitter, Austin police asked the public to "remain vigilant."

After bombing suspect Mark Conditt's death early Wednesday, authorities expressed concern there may be other package bombs circulating in public.

A friend of the suspected Austin bomber says he was an assertive person who would end up being "dominant and intimidating in conversation."

Jeremiah Jensen tells the Austin American-Statesman that he was close to Mark Anthony Conditt in 2012 and 2013. Jensen says they were both homeschooled in the same Pflugerville community and he would often go to the Conditt home for lunch after church on Sundays. He says they also attended Bible study and other activities together.

Jensen says, "I have no idea what caused him to make those bombs."

He says Conditt came from a good family, was athletic and a "deep thinker." He added that Conditt was "really rough around the edges" when they met.

Jensen says Conditt would "end up being kind of dominant and intimidating in conversation ... He really just wanted to tell the truth. What I remember about him he would push back on you if you said something without thinking about it."

A top FedEx executive says the company provided key evidence that helped identify the suspect in the bombings around Austin.

Chief Operating Officer David Bronczek said in a note to employees that FedEx was able to give the information to law enforcement "because of our advanced security capabilities and the vigilance of our team members."

Bronczek did not describe the information that FedEx provided, and company representatives declined to comment further. But Rep. Michael McCaul, chairman of the U.S. House Homeland Security Committee, said the suspect's "fatal mistake" was mailing a package from a FedEx store because it gave authorities surveillance video that showed him and his vehicle, including the license plate number.

Officials say the suspect, 23-year-old Mark Conditt, blew himself up in his vehicle overnight as authorities closed in on him. He is suspected of sending the package that blew up on a conveyer belt in a FedEx facility in Schertz, Texas, and another parcel with an unexploded bomb that was discovered at a FedEx facility near the Austin airport.

3:40 p.m.

Authorities say they've recovered homemade explosives from inside the home of the man responsible for planting a series of bombs around Austin.

The Austin Police Department and federal authorities said in a statement Wednesday afternoon that they were "working to safely remove and dispose of" the explosives at a home on Second Street in Pflugerville, just north of Austin.

That's the home suspected serial bomber Mark Conditt shared with roommates.

Authorities evacuated four blocks around the home "in an abundance of caution."

Police say Conditt built five bombs that exploded over three weeks, killing two people and severely wounding four others. He used one of his own devices to blow himself up overnight as a SWAT team closed in.

The chairman of the U.S. House Homeland Security committee says authorities seem to think the Austin bombing suspect had "above average intelligence."

Republican Congressman Michael McCaul told The Associated Press on Wednesday that the suspect matched the FBI's initial profile suspicion that the bomber was likely a white male. But he says a psychological profile probably won't be known until investigators go through Mark Conditt's writings and social media postings.

Authorities say Conditt blew himself up overnight in his vehicle in a hotel parking lot in another suburb as a SWAT team closed in on him.

McCaul says the suspect bought nails and other bomb-making equipment at a Home Depot but bought batteries for the devices on the Internet.

Bombing suspect Mark Conditt's family says they are "devastated and broken" at the news of his involvement.

Conditt's uncle, Mike Courtney, tells The Associated Press he doesn't "know that anybody saw this coming." Courtney described his nephew as a smart, intelligent and kind "computer geek."

The family's statement says they had "no idea of the darkness that Mark must have been in."

Austin police say Conditt died overnight after he set off an explosive device inside of his vehicle in a suburban Austin hotel parking lot as SWAT teams closed in.

Federal, state and local law enforcement agencies issued a news release Wednesday saying a federal criminal complaint and arrest warrant were issued Tuesday night for Conditt on a charge of unlawful possession and transfer of a destructive device.

The agencies say the investigation remains open and the documents remain under seal. They also repeated their warning that members of the public should report anything that looks suspicious, as there may still be bombs that haven't been found.

A neighbor of the Austin bombing suspect's parents says the couple homeschooled all four of their children.

Jeff Reeb said Wednesday that Mark Conditt's parents educated Conditt and his three younger sisters at their home in the Austin suburb of Pflugerville. The sisters ares 21, 18 and 13.

The 23-year-old Conditt enrolled in a community college in 2010 but didn't graduate.

Gov. Greg Abbott told KXAN-TV in Austin that Conditt was apparently unemployed when he began planting bombs, the first of which exploded March 2. In all, two people were killed and four others were seriously wounded.

Partially unsealed federal court documents show that agents from the Bureau of Alcohol Tobacco and Firearms were ready to arrest Mark Anthony Conditt on Tuesday on a charge alleging he had received, possessed or transferred destructive devices.

A U.S. Magistrate Judge heard by phone Tuesday an ATF agent's request to issue an arrest warrant for Conditt and signed the warrant electronically.

Many of the court documents remained sealed on Wednesday, including two orders from the magistrate and the cause for the warrant.

No other people are named in the criminal complaint cover sheet, which says Conditt is wanted for offenses between March 2, when the first bomb went off, and Tuesday, when the warrant was signed.

Authorities say Conditt blew himself up overnight in his SUV as a SWAT team closed in on him in an Austin suburb.

Texas Gov. Greg Abbott says the cellphone number of the Austin bombing suspect was of interest to law enforcement before he was captured on surveillance video at a FedEx store.

Abbott told reporters Wednesday that authorities used cellphone traffic data to put the suspect at the site of the explosions around Austin. He says the suspect's phone number drew the attention of investigators.

Police haven't released the suspect's name, but a law enforcement official who was briefed on the investigation identified him as Mark Anthony Conditt. The official wasn't authorized to discuss the case publicly and spoke on the condition of anonymity.

Abbott also said that among the items the suspect purchased at a Home Depot were five signs saying "CAUTION CHILDREN AT PLAY." He says he was told a tripwire that injured two men on Sunday in southwest Austin was tied to one of the signs, which would be consistent with what authorities have previously said about how the explosive was rigged.

Police said earlier Wednesday that the suspect was 24 years old, but Conditt is listed as 23 years old on his driver's license and other official documents.

Michael McCaul, a Republican from Austin who is chairman of the House Homeland Security Committee, told KXAN-TV that authorities retraced the suspect's steps after he was caught on surveillance video at an Austin-area FedEx store.

A Republican congressman from Austin is praising the work of law enforcement in tracking down the man suspected of planting four bombs this month in the Texas capital.

U.S. Rep. Michael McCaul, who is chairman of the House Homeland Security Committee, told KXAN on Wednesday that it was "really great police work" that led investigators to 24-year-old Mark Anthony Conditt.

Authorities say Conditt blew himself up overnight as a SWAT team approached his SUV in a motel parking lot outside of Austin. Police haven't publicly released Conditt's name, but a law enforcement official who was briefed on the investigation identified Conditt as the suspect on the condition of anonymity because the official hadn't been authorized to discuss the case publicly.

McCaul says he thinks the suspect's "fatal mistake was when he walked into a FedEx office to mail the package."

He says from that point, authorities could get surveillance video of him in his vehicle and his license plate number, and then identify him, see what he bought at Home Depot and track his cellphone.

A neighbor who watched the Austin bombing suspect grow up says he "always seemed like he was smart" and "polite."

Jeff Reeb said Wednesday that he's lived next to the parents of Mark Anthony Conditt for about 17 years and that they are good neighbors.

Reeb says Mark Conditt and his grandson played together into middle school and that Conditt visited his parents regularly.

The parents live a few miles from the Pflugerville home where Mark Conditt lived with roommates. Reeb says Conditt was in the process of gutting the house and remodeling it, which meant a lot of hammers and nails around frequently.

He says police had an unmarked car parked near Conditt's parents' house overnight into Wednesday. He says Condit's father, whom he called Pat, worked as an Amway distributor and also bought electronics on the side to resell.

Abbott says the suspect had no known military experience or criminal record.

He also says it is unclear if the bombs were made at the suspect's house or perhaps at the motel where he was arrested.

Abbott says investigators were watching the suspect for 24 hours, that his cell phone pinged in several different locations and that a key break in the case came when witnesses saw him at several stores wearing a blonde wig that looked odd to others.
