Someone please help me with this. I was on and found this entry listed in the Parental Incest trope. This was from an episode of the original L&O:

  • 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.

Someone please tell me which episode of the original L&O that this is from! Thank you! Would be much appreciated!
