On May 9 , 1980 , five men robbed the Security Pacific branch in Norco , California . They were among the most heavily armed bank robbers in history , carrying semi-automatic firearms , handguns , and improvised explosive devices , and succeeded not only in stopping several patrol cars but forcing a San Bernardino police helicopter to give up pursuit . By the end of the Norco shootout , a police officer and two robbers had been killed , with the other three suspects arrested and sentenced to life in prison
