Secret Service Uniformed Division officers attempted a traffic stop at the intersection of 17th Street and Constitution Avenue shortly before 1:30 p.m. local time on a vehicle with an expired registration, which indicated it would stop before fleeing the area, the statement said on Wednesday.
"The suspect then crossed a red traffic signal and struck multiple individuals in the crosswalk," the statement added. "One person was transported from the scene in critical condition and later succumbed to injuries at an area hospital."
The suspect fled in a southbound direction and a lookout notice has been broadcast to law enforcement agencies in the area, according to the statement.
