The defendants, Kyle Harrison, 23, and a 17-year-old were allegedly drag racing before 8 p.m. on Nov. 4, driving more than 80 miles per hour on El Camino Real when the minor's vehicle collided with Grace Spiridon and Gregory Ammen's car, which was turning left onto El Camino Real from Finger Avenue. 

Ammen and Spiridon’s car was projected into the air and off the road, killing the parents instantly, according to the San Mateo County District Attorney's Office. Their 7-year-old twin daughters were injured but survived. Two others, who were in the teen's car, were also injured.

The 17-year-old was transported to Stanford Hospital with non-life-threatening injuries and arrested upon his release two weeks later.

Harrison left the scene, but a photo of his license plate captured by a witness led to his arrest Monday.  

The juvenile’s case will be transferred to criminal court. Harrison remains in custody without bail.
