The mother passed away last year after being hit by a drunk driver. He says CC and Ruth talked about everything. CC was happy til high school. CC wasn't in with the in crowd and didn't think she was pretty. There was nothing they could do or say to convince her otherwise. Her first crush was a lawyer now in LA. Benson asks if it was possible CC tried to get ahold of them? Mr. Taylor says they prayed every night for a sign she was a live. 7 years ago they had a fake funeral for her. It It didn't help.
Fin and Carisi interview Heath's old landlord. She says she doubts any girl moved in with Heath because Heath was fixated on this girl in med school who didn't want him. Fin and Carisi ask to look in the basement. They find it is the place where the video was shot. Ms. Kimball never noticed a panel on the wall. The detectives send her away and tear out the wall. They find a body. Mrs. Kimball comes back with water or tea or something and drops the cups.
