Richmond residents Darian Holly, 16, and his sister Mercedes Williams, 19, were standing with a group of people in front of a home in the 4100 block of McLaughlin Street around 9:45 p.m. when two suspects approached and opened fire, Richmond police Lt. Bisa French said.
The siblings were struck by the gunfire and pronounced dead at the scene, French said.
The two male suspects ran away and also shot at a vehicle, but the sole occupant of the car was not struck, French said.
The pair then got into a dark blue vehicle and drove south away from the scene, French said.
The two remain at large as of this morning, she said.
Other members of the group were not injured in the shooting, French said.
