Texas Gov. Greg Abbott said on Wednesday that he had little information about Conditt, but he could confirm that he was unemployed.
“He did not have a criminal record as best we can tell, so there seems to be very little information about him,” Abbot told KXAN, adding that investigators would look through any social media accounts.
He said Conditt had two roommates who were cooperating with law enforcement.
One of Conditt’s roommates was taken into custody on Wednesday morning, but he was later released, Austin police said. The other was being questioned but had not been arrested, according to authorities.
A 2012 blog, which appears to be part of a government class project at Austin Community College, lists the writer as Mark Conditt of Pflugerville, Texas. Conditt is believed to have been a resident of Pflugerville, north of Austin.
NBC News could not immediately confirm if the blog was written by the suspect, but public records show only one Mark Conditt in Pflugerville. Austin Community College confirmed that a “Mark Anthony Conditt,” born in June 1994, was a student from 2010-12, but did not graduate. The college added that it is “working with Austin Police Department to provide any information they need.”
The blog espouses some political beliefs, including entries describing why the author believes gay marriage should not be legalized and why the United States should do away with sex offender registration.
Jeff Reeb, a neighbor of the Conditt family, said that Mark was “a very normal kid” and that the family is “extremely nice.”
The suspect’s grandmother, Mary Conditt, shared a statement on behalf of the family on Wednesday afternoon in which they requested privacy “as we deal with this terrible, terrible knowledge and try to support each other at this time.”
“We are devastated and broken at the news that our family member could be involved in such an awful way,” the family said. “We had no idea of the darkness that Mark must have been in. Our family is a normal family in every way. We love, we pray, and we try to inspire and serve others. Right now our prayers are for the families who lost loved ones, for those impacted in any way, and for the soul of our Mark.”
Shortly after the announcement that the suspect had been killed, President Donald Trump congratulated law enforcement personnel.
Even though the suspect was dead, however, officials warned locals to keep on the lookout for other possible explosives.
“This is the culmination of three very long weeks for our community,” Manley said. “We still need to remain vigilant to ensure no other packages or devices have been left in the community.”
ATF Special Agent in Charge Fred Milanowski told reporters that officials were “concerned that there may still be other devices out there.”
