(KRON) -- A street racer who caused a tragic Redwood City crash that killed the parents of twin girls has been sentenced to 90 days of electronic home monitoring. Cesar Morales’ sentence was delivered Thursday in San Mateo County Juvenile Court on his 20th birthday. Morales was 17 years old on Nov. 4, 2022, when the deadly crash happened on El Camino Real. According to prosecutors, the Redwood City teen was sitting in his Mercedes at a stoplight on El Camino when a BMW being driven by 25-year-old Kyle Harrison pulled up. The two drivers, who investigators said were strangers, agreed to a street race as the light turned green. The Mercedes and the BMW sped off, reaching speeds of over 80 to 90 miles per hour before reaching the victims’ car on the roadway. Gregory Ammen and Grace Spiridon, along with their twin 7-year-old daughters, were driving to their San Carlos home in the family’s Chevrolet Bolt. The family was turning left from Finger Avenue onto El Camino Real when the 17-year-old’s Mercedes broadsided the Bolt, sending the family’s car into the air and off the road. The family's mangled car is seen on El Camino Real in Redwood City on Nov. 4, 2022. The two parents were killed “instantly” from the impact, prosecutors said. The twin daughters, Madison and Olivia, miraculously survived the horror in the backseat. Morales was injured in the crash and located at the scene by responders. Harrison fled in his BMW and was found and arrested two weeks later. Judge Susan I. Etezadi denied the prosecution’s request to move Morales’s case to adult court in June. On Nov. 20, 2024, the judge found the following allegations true: Two counts felony vehicular manslaughter Three counts felony engaging in a speed contest and causing great bodily injury One count engaging in a speed contest Allegations in two counts of second-degree murder were found by the court to be not true.

Judge Etezadi ultimately sentenced Morales to 90 days of electronic home monitoring, following the probation department’s recommendation. The sentence will require that Morales stay at home with his parents “at all times except school, medical appointments, etc.,” according to the DA’s office. Morales was released from custody Thursday afternoon to his parents. Harrison pleaded no contest in October 2024 to two counts of vehicular manslaughter. He faces up to nine years and four months in state prison. Sentencing is scheduled for Feb. 25, 2025. A GoFundMe supporting the orphaned girls raised $582,787.
