Hearst and the Harrises escaped, but all were captured 16 months later in San Francisco. Asked her occupation when she was being booked, Hearst answered "urban guerrilla." She was tried and convicted of bank robbery; she served 21 months before her sentence was commuted by President Jimmy Carter. She later married and had two daughters by Bernard Shaw, a former San Francisco police officer who served as one of her bodyguards during her legal proceedings. He died in December at age 68.

In a 2002 interview with Larry King after other SLA members had been arrested for murder during a 1975 bank robbery in Sacramento, Hearst described the process by which she became willing to take part in the SLA's crimes:

HEARST: Larry, most of the time I was with them, my mind was going through doing exactly what I was supposed to do.

KING: What you were told?

HEARST: Yes. I mean -- even if I weren't told, I had been educated very well in what to do. I had been, you know, held in the closet for two months and, you know, abused in all manner of ways. I was very good at doing what I was told. And as far as thinking...

KING: Was that Stockholm Syndrome part of the thinking or not?

HEARST: I'm sure it was. Of course it was. I mean, they call it Stockholm Syndrome and post-traumatic stress disorder. And, you know, I had no free will. I had virtually no free will until I was separated from them for about two weeks. And then it suddenly, you know, slowly began to dawn that they just weren't there anymore. I could actually think my own thoughts. It was considered wrong for me to think about my family. And when Cinque (SLA leader Donald DeFreeze) was around, he didn't want me thinking about rescue because he thought that brain waves could be read or that, you know, they'd get a psychic in to find me. And I was even afraid of that.
