Having heard nothing from their daughter since June, the Hearst family withdrew their offer of a $50,000 reward for the safe return of Patty Hearst.
On 21st April 1975, four members of the SLA held up a bank in Carmichael, California, and an innocent bystander, 42-year old Myrna Opsahl, was killed during the robbery. Hearst was not one of the four involved in the raid.
Finally, on 18th September 1975, following her return to the West Coast, Hearst was arrested in San Francisco, along with fellow SLA members Bill and Emily Harris, and Wendy Yoshimura. When she was taken to the police station to be booked, she told the desk sergeant that her occupation was 'urban guerrilla'.
