AUSTIN, TX - Mark Anthony Conditt was named Wednesday as the serial bomber behind the string of blasts that terrorized Texas for three weeks and left two people dead, as officials warned residents that other explosive devices may still be out there.
Authorities say Conditt blew himself up in his vehicle in a hotel parking lot in another suburb as a SWAT team closed in on him on Wednesday morning. Investigators believe Conditt made all of the bombs used in the four Austin attacks, which killed two people and injured four others.
The first photo of Conditt, from 2013, emerged Wednesday morning and was authenticated by the Austin American-Statesman. The picture came from the Facebook page of his mom, Danene Conditt, who appeared to be celebrating Mark's high school graduation.
"I officially graduated Mark from High School on Friday," her post said. "1 down, 3 to go. He has 30 hrs of college credit too, but he's thinking of taking some time to figure out what he wants to do….maybe a mission trip. Thanks to everyone for your support over the years."
Conditt, who a law enforcement official identified as the Austin bomber, can be seen in surveillance photos obtained by Fox News dropping off two suspicious packages on Sunday from inside a South Austin FedEx Office store on Brodie Lane.
Texas Gov. Greg Abbott told "FOX & friends" authorities were able to gather information, in addition to the surveillance video showing Conditt in a "disguise" of a blonde wig and gloves to piece together various pieces of the puzzle to give law enforcement the ability to track him down.
Conditt was home-schooled and went to Austin Community College, according to neighbors. A spokeswoman for a community college says the suspected Austin bomber was a student there from 2010 to 2012 but didn't graduate. He and his father, Pat Conditt, purchased a Pflugerville property last year that is now valued at about $69,000, according to property records.
A neighbor who watched the Austin bombing suspect grow up says he "always seemed like he was smart" and "polite," according to AP reports. 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.
Conditt had worked at Crux Semiconductor, a manufacturer "solutions" company, in Austin as a "purchasing Agent/buyer/shipping and receiving," according to a profile on a job recruiting website, and had previously worked as a computer repair technician, according to the Statesman.
Meanwhile, authorities boasted of uncovering a "treasure trove of information" about the dead 24-year-old -- but officials warned other explosives may still be out there, and other collaborators may be on the loose.
"We don't know where this suspect has spent his past 24 hours, and therefore we still need to remain vigilant to make sure that no other devices have been left out in the community," Gonzales told reporters.
Austin Police Chief Brian Manley said communities surrounding Round Rock, where Conditt blew himself up as SWAT officers closed in, should "remain vigilant" as officials work to put together a timeline for where the suspect has been.
Abbott told "FOX & Friends" the suspect did not destroy his digital footprint, and that there is a "treasure trove of information that should shed light on who he is, what he did, and why he was doing it."
Abbott said Conditt, who is not ex-military, did not post things on social media beforehand that would be "red flags," and that he lived with two roommates in Pflugerville, located about 20 miles north of Austin.
"Those two roommates have been talking to law enforcement," Abbott said, adding they are not suspects at this time.
The Texas governor said authorities are now going to spend the next 24 hours trying to figure out if anyone else was working with Conditt, and if there are any other bombs out there.
Conditt didn't appear to have left much of a trail on social media, but in 2012 posts on what appears to be his personal blog he expressed opinions about a range of topics, including gay marriage.
A blogger who identified himself as Mark Conditt of Pflugerville, made six entries, all in 2012, in which he wrote that he thinks gay marriage should be illegal and that sex offender registries should be eliminated, according to a copy of the posts obtained by TMZ.
"You have to really hate the guy to make him suffer for the rest of his life, even when his prison time is up," he wrote.
He also described his interests as cycling, tennis and listening to music, according to images of the blog posted by TMZ.
FBI Agent Christopher Combs, head of the agency's San Antonio office, said authorities have a "long day ahead" as they work to go through "exactly what happened."
"We are concerned there may be other packages still out there, we need the public to remain vigilant, especially today as we go through the investigation," Combs said.
