The trial of a Randolph man charged with gunning down a high school football star outside a Brockton house party nearly seven years ago is getting started. The Enterprise reported that Andrew Robert Brewer faces first-degree murder and firearms charges when his trial starts Wednesday. Prosecutors said the 25-year-old Brewer shot 17-year-old Jose Gurley in July 2007. Police said at the time that Gurley may have been trying to break up a gang fight. Brewer was arrested four years later based on witness accounts of the shooting. Gurley was a star player on the West Bridgewater High School football team, helping to lead the team to a state championship.
