Gunman likely killed by Customs and Border Protection SWAT team member
Authorities believe the Uvalde school shooter was shot and killed by a member of the Customs and Border Protection's tactical unit, known as BORTAC, CBP Del Rio Sector Chief Jason Owens told ABC News.
Owens, who did not identify the agent, said his actions "were absolutely courageous," but added it wouldn't be fair to single anyone out.
"It would be unfair to say that any one person's actions were singularly responsible for ending that threat," Owens said. "It took everybody."
