A man was shot and killed outside a Vallejo supermarket Tuesday afternoon drawing a hostile crowd that took four law enforcement agencies to contain, Vallejo police said.
The shooting was reported at 3:40 p.m. in front of King's Market at 1624 Fairgrounds Drive, police said.
The man in his 20s was pronounced dead at the scene. His name has not been released.
After police arrived, a large hostile crowd formed, leading police to call for help from American Canyon police, the California Highway Patrol and the sheriff's offices from Napa and Solano counties.
The officers secured the crime scene and continued with their investigation, police said.
