Riley Howard of San Jose died after a two-car collision Friday, and mourners gathered at the crash site the following day.
CUPERTINO, Calif. — A memorial of flowers, candles and a photograph marked the site of a deadly Cupertino crash Saturday after authorities identified the child who died as 2-year-old Riley Howard of San Jose.
The County of Santa Clara Office of the Medical Examiner identified Riley after the two-car collision Friday near Apple Park. The crash happened shortly after noon at North Tantau Avenue and Pruneridge Avenue, near the Apple Park Visitor Center. Riley was taken to a hospital in critical condition and later died. An adult woman who was also seriously hurt remained hospitalized in critical condition, according to reporting Sunday.
Firefighters arriving at the scene found two damaged vehicles, including one that was on fire, according to Santa Clara County fire officials. Bystanders found the child unconscious and began CPR before emergency medical crews arrived. The actions unfolded along a busy stretch of road next to Apple’s Cupertino campus as first responders worked to treat the injured and secure the crash scene.
Witness Jerry Pannone told ABC7 News that he heard the impact and then saw a car spin, with sparks coming from the vehicle as it struck the curb. Authorities have not released a full reconstruction of the collision, and the witness account does not establish what caused the crash. Investigators have continued working to determine how the two vehicles collided.
The adult woman was in the same vehicle as Riley, according to ABC7 News, but authorities had not publicly explained their relationship as of Sunday. The driver of the other vehicle, an adult man, suffered minor injuries and was taken to a hospital for treatment. He was released from the hospital and later arrested by Santa Clara County sheriff’s deputies.
The Sheriff’s Office said investigators developed probable cause to arrest the man on suspicion of gross vehicular manslaughter. His name had not been released in the reports reviewed Sunday. The arrest is part of an ongoing investigation and does not amount to a finding of guilt. Authorities also had not publicly released a detailed account of the evidence that led to the arrest.
Investigators with the Sheriff’s Traffic Accident Reconstruction Specialist Team responded to the collision and began examining the circumstances surrounding it. Tantau Avenue was closed in both directions for several hours after the crash as authorities investigated the scene. Officials have not announced a final cause of the collision.
Capt. Neil Valenzuela of the Sheriff’s Office West Valley Patrol Division described the collision as a heartbreaking tragedy and expressed sympathy for the child’s family and loved ones. The memorial that appeared at the intersection Saturday gave the public its first visible place to mourn after Riley’s identity was released, with flowers and candles arranged near a photograph of the toddler.
The crash drew attention in part because of its location beside Apple Park, but authorities have described the case as an active traffic investigation. No information released by investigators has indicated that Apple or its facilities caused or contributed to the collision. The crash occurred on public roads near the company’s headquarters and visitor center.
As of Sunday, investigators were still working to establish the circumstances that led to the crash. The woman injured alongside Riley remained hospitalized in critical condition, while the man arrested after being treated for minor injuries remained under investigation in connection with the child’s death.
