The police officer who was killed outside the Pentagon on Tuesday, August 3, has been identified as George Gonzalez, an Army veteran and member of the Pentagon Force Protection Agency.

According to reports, the officer was ambushed and stabbed in the neck by the suspect. The attacker then shot himself with the officer’s weapon and then became engaged with other officers. During the incident, the suspect was shot and killed, however, it is unclear which officer killed the assailant, CNBC reported.

After multiple gunshots were fired near the Pentagon early Tuesday morning, the Pentagon was placed in lockdown, but it was reopened after more than an hour. Although the lockout has been lifted, the Pentagon Force Protection Agency warned that the metro rail entrance and bus platform area is still “an active crime scene.”

The exact details and sequence of events are yet unknown. The Pentagon Force Protection Agency’s police chief, Woodrow Kusse, claimed at a press conference that the incident resulted in “several injuries.”

One civilian was also injured during the incident, and was taken to a hospital with “non-life-threatening injuries.” The bystander was later released.

During the briefing, Pentagon Force Protection Agency Chief Woodrow Kusse discussed the status of the incident, claiming that authorities aren’t actively looking for a new suspect. “The incident is over, the scene is secure, and most importantly, there is no continuing threat to our community,” he said.

The incident is being investigated by the FBI, as the motives for it are yet unknown.

“At this time, it would be premature to speculate on motive, and in order to protect the integrity of the investigation we cannot provide additional details at this time,” the FBI Washington Field Office said in a statement. “There is no ongoing threat to the public.”

According to OANN, Kusse answered a question about the Pentagon Metro entrance— if the incident would require “additional force protection measures.” He stated that a number of procedures were already in place, but that they will be reevaluated.

“We will certainly, as this investigation concludes, take another look at any measures,” he explained. “Our mission is to protect not just the building, but the community we serve that transits through that station.”

Virginia Democrat Sen. Mark Warner tweeted on Twitter on Tuesday afternoon, “I’m incredibly saddened to learn about the passing of a Pentagon police officer, who was killed earlier this morning in a senseless act of violence outside the Pentagon.”

“My heart goes out to the officer’s family and friends, as well as the entire Pentagon Police force,” Warner, the chairman of the Senate Intelligence Committee, said.

U.S. Secretary of Defense Lloyd Austin also requested flags on the Pentagon reservation to be flown at half-staff “in honor of his loss.”
