A jury yesterday (Aug. 11) found two drivers and the parents of one of the drivers liable in a civil case stemming from a 2022 Redwood City crash that killed the parents of 7-year-old twin girls, awarding the family $33 million.
A family of four — Greg Ammen, Grace Spiridon and their twins — were driving home from the girls’ grand-mother’s home on Nov. 4, 2022, when they were struck by a car moving 100 mph, killing both Ammen and Spiridon.
They were less than 10 minutes away from their San Carlos home at the time of the crash.
Yesterday the jury found the driver, Cesar Morales, who was 17 at the time of the crash, Kyle Harrison, who was racing Morales at the time, and Morales’ parents, Arnold Morales and Susana Salto Alvarez, were all liable for the crash. “While nothing can undo what happened, we are deeply grateful that the jury gound Grace was not at fault,” Grace Spiridon’s sister Liza Spiridon said in a statement. “Our focus remains on helping these girls heal while honoring the beautiful lives of Grace and Greg.”
Morales’ parents, the lawsuit alleged, were aware of their son’s “proclivity for reckless driving.”
The lawsuit cited speeding tickets Morales recieved that were sent to his parents’ home as a way the parents knew. Morales’ parents countered that they didn’t know about the tickets until after the crash, which is when Arnold Morales found a blue folder with the tickets, alleging Cesar Morales was caught driving over 100 mph.
Criminal court outcomes
Morales was found guilty in January 2025 of vehicular manslaughter, but got credit for time served and was released the day he was sentenced, as he had been in jail since the crash.
Harrison took a plea deal for lesser charges involving the speed contest as he did not hit the family but was sentenced to eight years in prison in Feburary
2025. A month later, Harrison died in the county jail after ingesting a toxic mix of medications. His family is suing the county for alleged negligence and wrongful death.
At the time of his death, Harrison was making plans to get a job after getting out of jail to make court-ordered payments to the girls, his attorney Tennille Duffy previously told the Post.
Morales and his parents have filed a lawsuit in federal court against Redwood City, CHP and multiple county officials, claiming Cesar Morales’ rights were denied during the investigation and during the proceedings in juvenile court.
The crash
Morales and Harrison were at a stoplight and agreed to race. The two drove between 80-105 mph in an area with 35 mph speed limit.
Morales T-boned the family’s car, which was turning onto El Camino, the District Attorney’s Office previously said. The car was launched into the air and landed off the road, killing Spiridon and Ammen.
The couple grew up in Palo Alto, knowing each other for years before getting together in their 20s, family friends previously told the Post.
