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.
