A man charged with manslaughter in the deaths of a San Carlos couple following a street racing incident that left their twin daughters orphaned has pleaded no contest to multiple felony charges stemming from a street racing incident. His sentencing is scheduled for Dec. 2 in San Mateo County Superior Court.
Kyle Harrison, a 25-year-old Redwood City resident, is facing up to nine years and four months in state prison.
On Nov. 4, 2022, Harrison, driving a BMW, was allegedly involved in a street race with a juvenile stranger in a Mercedes. The two pulled up to a traffic light at the intersection of El Camino Real and Howard Avenue in San Carlos. According to law enforcement, the teenager, Cesar Morales, encouraged by his two unidentified minor passengers, challenged Harrison to a race. Both drivers revved their engines, and when the light turned green, they sped off, reaching speeds of 80-90 mph.
Morales’s Mercedes crashed into a Chevrolet Bolt, which was making a left turn onto El Camino from Finger Avenue. Inside the Bolt were Gregory Ammen, 44, and his wife Grace Spiridon, 42, along with their 7-year-old twin daughters. The incident crushed the car, sending it airborne and off the road. Both Ammen and Spiridon were killed instantly, but their daughters miraculously survived.
Harrison fled the scene, but a witness captured his license plate on her phone. He was arrested two weeks later. Morales, who was 17 at the time, was also injured in the crash and remained at the scene. He will be tried in juvenile court for two counts of second-degree murder.
This month the prosecution added additional charges of vehicular manslaughter to which Harrison pleaded no contest. He is now facing a total of 8 charges.
Harrison remains in custody without bail and is represented by defense attorney Tennille Duffy.
