Mountain View police announced the arrests of five men in connection with a murder and an assault at a June 18 concert at Shoreline Amphitheatre.

MOUNTAIN VIEW, Calif. -- Mountain View police announced the arrests Wednesday of five men in connection with a murder and an assault at a June 18 concert at Shoreline Amphitheatre.

Police said in a news release Wednesday that the five men -- 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.

Following a five-month investigation, officers executed arrest and search warrants at the homes of the suspects -- as well as a search warrant at the motorcycle clubhouse in San Francisco -- in coordination and collaboration with several local and federal partners.

"This was an extremely sensitive situation," Chief Chris Hsiung said in the announcement. "We knew early on that we needed to be meticulous and diligent in our pursuit of justice for the victims in these cases."

According to the announcement, Mountain View officers responded during the concert to reports shortly before 10:45 p.m. of a man -- later identified as Gonzalez -- who was found unresponsive near the Stage Right Cafe at the venue. Emergency responders, including Mountain View firefighters, attempted life-saving measures and the man was rushed to an area hospital for further treatment.

About a week later, Gonzalez succumbed to his injuries and died.

Also during the concert that night, an off-duty police officer was brutally assaulted by a group of men near a collection of portable restrooms before they walked away from the area.
