A suspected gunman who ambushed Dallas police headquarters Saturday morning was shot during a standoff and was later confirmed dead, police said.

SWAT snipers struck the suspect through the windshield of his van in the Dallas suburb of Hutchins during a tense ordeal in which no officers or civilians were hurt, Dallas Police Chief David Brown told reporters. The Dallas police tweeted Saturday afternoon that he was killed.

The suspect identified himself as James Boulware to police, although officers had not confirmed his identity. Brown said officers needed to check the suspect’s fingerprints once they were able to get into the van to verify his identity
