I am a fan of the L&O franchise and a contributor on Evil Babes Wikia, and I need help here! I got this from TVTropes:
There's an episode about the murder of a teenage girl. The cops keep pursuing the girl's father, as evidence indicates the girl was sexually abused, but he keeps protesting his innocence. It's ultimately revealed that it was the girl's mother who was raping her and ultimately murdered her.
According to TVTropes, it's an episode of the original L&O. Can someone PLEASE tell me what episode of the original L&O this is from? Thank you so much!
