UPDATE 10:54 p.m. What started as a routine traffic stop turned into a tragedy — police confirmed that one of the two women who was hit died.

The Secret Service had originally seen a silver Buick and noticed that the tags did not match the car. Officers approached the car, and the man drove off at a high speed, police said.

One witness DC News Now spoke with estimated it could have been around 50 miles an hour.

Investigators said the driver went through a red light at the intersection at 14th Street and New York Avenue NW before hitting a car and then hitting the two women who were crossing the street.

The woman who died passed away at the hospital. The other woman is in critical condition.
