Law & Order: Special Victims Unit Season 1 Episode 16

An elderly woman is found tied up and sexually assaulted in her apartment, and suspicion is initially on the young men that had broken into her home and robbed her, but once the detectives catch the young men, they learn that there was someone else in the apartment. The offered plea bargain initially doesn’t go over well, but they finally reach a deal which leaves the detectives with a new case — whether or not the person that sexually assaulted the woman was mentally handicapped.
