Casey told Cindy in the tape that she knew Lee was there because she saw Mallory's car in front of the house on the live TV she was watching just then from jail. Christine gets on the phone and tells Casey that the only people at the house are Christine, Casey's parents, and Lee.I think Lee's girlfriend's name is Mallory. Kristina is a friend of Casey's.
So who's Mallory? LOL, this whole bunch lies to each other, and they all believe each lie, no matter how illogical!
