In brief comments to The Associated Press on Tuesday, Cyrus Reed's mother, Lucy Reed, said the family met Bryce for the first time at the April 25 memorial.
"No comment except Bryce is not my son," she said.
Although Reed portrayed himself as a West EMT in the Baylor video and other public appearances after the explosion, he was in fact dismissed two days after the blast, records show.
Questions also have arisen about Bryce Reed's academic credentials and work history.
At least two of the educational institutions listed by Reed on his LinkedIn profile page — the University of Phoenix and the University of Texas Southwestern Medical Center — say they have no records of him being enrolled.
In an email to the Texas Department of State Health Services last Friday, Christine Reeves of the Heart of Texas Regional Advisory Council wrote that the West EMS administrator, Tom Marek, "asked that I contact you guys that Bryce Reed does not volunteer for West EMS" and was "let go" on April 19.
Marek declined to comment Wednesday. Reeves told the AP she wasn't informed of a reason for the dismissal.
Reed has been a licensed EMT since 2005 and has worked for at least one other agency, an air ambulance service, state records show. No complaints have been lodged against him, and no disciplinary action has been taken, the records show.
Carrie Williams, the spokeswoman for the Texas Department of State Health Services, said the agency initiated an investigation into Reed's license as a result of his arrest. Such investigations are standard procedure when the department learns that an EMT is charged with a felony, she said.
