In April, however, the situation changed dramatically when a surveillance camera took a photo of Hearst participating in an armed robbery of a San Francisco bank, and she was also spotted during a robbery of a Los Angeles store. She later declared, in a tape sent to the authorities, that she had joined the SLA of her own free will.
On May 17, Los Angeles police raided the SLA’s secret headquarters, killing six of the group’s nine known members. Among the dead was the SLA’s leader, Donald DeFreeze, an African American ex-convict who called himself General Field Marshal Cinque. Patty Hearst and two other SLA members wanted for the April bank robbery were not on the premises.
Finally, on September 18, 1975, after crisscrossing the country with her captors–or conspirators–for more than a year, Hearst, or “Tania” as she called herself, was captured in a San Francisco apartment and arrested for armed robbery. Despite her claim that she had been brainwashed by the SLA, she was convicted on March 20, 1976, and sentenced to seven years in prison. She served 21 months before her sentence was commuted by President Carter. After leaving prison, she returned to a more routine existence and later married her bodyguard. She was pardoned by President Clinton in January 2001.
