An alert witness helped Watonsville Police officers arrest a man Sunday, after he allegedly hit a child with his van, and fled the scene. Officers responded just before noon, to the report of a hit and run that occurred at Lincoln and Elm Streets. While responding, they received a report that a witness had followed the suspect, 21-year-old Ruben Bautista. Officers were able to obtain the van's license plate number, and located Bautista near Tuttle Avenue. Bautista was booked into Santa Cruz County Jail for hit and run resulting in injury, as well as driving without a license. The 7-year-old victim was air-lifted to a south bay trauma center, to be treated for what police described as “minor” injuries.
