Prosecutors said Mountain View police believe that Franklin Enrique Sarceno Orla may have assaulted many more victims and are asking those people to come forward. 

The five suspects, who appear to be associated with the Hells Angels Motorcycle Club in San Francisco, were arrested Tuesday as suspects in the murder of 41-year-old Bakersfield resident Juan Gonzalez and the brutal assault of an off-duty police officer at a Chris Stapleton concert. 

The officer, who has not been identified, was hospitalized with non-life-threatening injuries.

Investigation by Santa Clara County's cold case unit and Mountain View police led to the July 9 arrest of John Kevin Woodward at JFK airport in New York City for the strangulation murder of Laurie Houts 30 years ago. Woodward will stand trial for a third time in the case.
