(KRON) -- A Santa Clara man is suspected of speeding before a collision that killed a young child in Cupertino Friday. Eric Chen Su, 38, was arrested on suspicion of gross vehicular manslaughter.
The deadly crash occurred just after noon at the intersection of North Tantau and Pruneridge avenues, near the Apple headquarters. Arriving first responders found a San Jose woman and child from one vehicle suffering from major injuries, and Su from a second vehicle with minor injuries, according to the Santa Clara County Sheriff’s Office.
All three were hospitalized. Despite lifesaving efforts, the child later died.
Su was arrested after investigators determined that speed was a “considerable factor” in the crash, the sheriff’s office said Monday. Authorities are awaiting lab results, which will indicate whether alcohol or drugs were contributing factors.
