Overview

• Danville Police Department and Contra Costa Sheriff’s Office officers executed a warrant Friday to arrest 73-year-old Andrew Chao on felony vehicular manslaughter charges.
• The charges stem from a March 1 collision at the Sycamore Valley Road and Camino Ramon intersection that overturned a truck and killed its passenger.
• Detectives investigated the crash over several months before presenting their findings to the Contra Costa District Attorney’s Office in July, leading to the indictment.
• Chao, who sustained minor injuries in the collision, was booked into the Martinez Detention Facility following his arrest.
• The crash was Danville’s first fatal collision of the year and has focused attention on safety at the busy I-680 onramp-offramp interchange.
