After another gunshot to the leg, the second victim was able to break free and was transported to the hospital, Benedict said. As the shooter went further down the escalator, a third altercation occurred "with a woman at this point," attempting to rob her "or get in some kind of altercation with her." Trying to de-escalate the situation, Cunningham attempted "to intervene to protect this young lady. By doing so, he is immediately shot by [the] shooter," Benedict continued, announcing that the man has since been "pronounced" dead. "His heroism has to be recognized here today."

The city's Mayor, Muriel Bowser, stated that they "do not know much about the shooter at this moment" other than the fact that they "had a person with a gun who has created yet another tragedy in our city," Bowser said of the suspect who was arrested at the platform, before paying her respects to the family of the deceased employee. "Our thoughts and prayers go out to his family," Benedict said, once again acknowledging "the heroic actions that took place today." PEOPLE has reached out to the Washington, D.C.
