Two Redwood City drivers, including a 17-year-old, have been arrested and face second-degree murder charges for their involvement in a major vehicle crash that resulted in the death of a San Carlos couple and multiple injuries, according to the Redwood City Police Department.

The defendants, 23-year-old Kyle Harrison and a 17-year-old male, were allegedly drag racing just before 8 p.m. on Nov. 4 when the minor’s vehicle collided with a car containing a family of four at the intersection of El Camino Real and Finger Avenue, police said on Monday in a news release.

Gregory Ammen, 44, and Grace Spiridon, 42, Palo Alto natives and residents of San Carlos, were in the other car in the collision and died in the crash. Four other passengers were also injured, including two in the teen’s car and Ammen and Spiridon’s 7-year-old twin daughters.

The 17-year-old was arrested on Nov. 18 and booked into the San Mateo County Youth Services Center, after spending two weeks at Stanford Hospital, according to officials. Harrison was arrested at his residence on Nov. 21 and was booked into the San Mateo County Jail, police said.

A police investigation determined that two cars were engaged in a speed contest that caused the fatal accident. The drivers are facing two counts of second degree murder and, if convicted, could serve 15 years to life in prison.  

The defendants will appear separately before judges Tuesday afternoon.

Anyone who has information is encouraged to call the RCPD tip line at 650-780-7107.
