Brunner drove a white van to a Hawthorne, California Western Surplus Store on August 21, 1971, accompanied by Family members Catherine "Gypsy" Share, Dennis Rice, Charles Lovett, Larry Bailey, and Kenneth Como. The group brandished guns and ordered patrons and clerks to lie on the ground. They then took 143 rifles, loading them into their van, while a store clerk tripped the silent alarm. According to police officers, the group then debated whether to kill all of those in the store.
