Villainous deceased rapist Sidney Green
Sidney Green was the tertiary (redeemed) villainess from "Ridicule," episode 3.10 of Law & Order: SVU (airdate December 14, 2001). She was the ex-wife of Andrew Green and an associate of defense attorney Pam Adler.
Sidney's brief backstory revealed that she and Andrew met when she was in rehab due to a painkiller addiction. As revealed by Andrew, the couple was fighting due to the fact that Sidney was using again, and it was during her bachelorette party that she participated in the rape of Peter Smith, a male stripper. The evil Sidney committed the rape along with Pam and another associate, Amelia Chase, and as a result, she was on the receiving end of a $5 million civil suit filed by Peter.
Sidney later planned on setlling and coming clean and revealing Pam and Amelia as her cohorts. She was meeting with Peter's lawyer to do just that, but she was later killed by Amelia, who colluded with Pam in the murder to silence Sidney. It was Amelia's use and knowlege of auto-erotic asphyxiation that killed Sidney.
