Peggy Caserta, Who Wrote a Tell-All About Janis Joplin, Dies at 84
"She spent months in a Mexican prison by choice, pretending to be the partner of a man incarcerated there. The prison was rather lax and allowed conjugal visitors to stay for weeks, which she did while helping her friends dig an escape tunnel. (She stayed longer than necessary to ensure their success because the drugs inside were, to her, so good.)"
