The autopsy of the street racer who died while in custody at the Maple Street Correctional Center was found to be “inconclusive,” according to San Mateo County District Attorney Steve Wagstaffe.
Kyle Harrison, who died on March 15 in a jail cell occupied by him and one other incarcerated individual, had his autopsy conducted by San Mateo County Coroner Robert Foucrault’s office, who did not definitively identify a cause of death, according to Wagstaffe.
Samples from the autopsy were sent to an offsite lab for toxicological analysis. Results can take a few weeks to a few months, according to Wagstaffe. The National Institute of Justice defines forensic toxicology as “the analysis of biological samples for the presence of toxins, including drugs.”
The San Mateo County Coroner’s Office confirmed that toxicology samples are generally sent to a private lab, but no supervisors were available on Monday to release the name of the lab that held Harrison’s samples.
“I remain sad about Mr. Harrison’s death,” Wagstaffe said. “It’s one of those cases where he did everything right after the initial incident and you are hoping he can serve his debt to society and then recover but for him to die, before he was even transferred, it’s just sad.”
On Nov. 4, 2022, Harrison was involved in a street race when then-17-year-old Cesar Morales crashed into a car, killing San Carlos residents Gregory Ammen, 44, and Grace Spiridon, 42, and injuring their 7-year-old twin daughters.
Harrison was sentenced to eight years in prison on Feb. 15, but had less than two years of jail time remaining due to credits for good time and time served. Morales spent roughly two years in juvenile detention awaiting sentencing and was later sentenced to 90 days of electronic home monitoring.
Since Sheriff Christina Corpus took office in 2023, six inmates, including Harrison, have died while incarcerated.
