Logan is arrested, and once released he angrily breaks up with Veronica for providing the evidence against him. He tells her that when he saw Lilly after returning from Mexico, he knew their relationship was over and wrote her a letter, which he left in Lilly's car along with the shot glass. Veronica realizes that the letter was never found, and sneaks into a dinner party at the Kane household to search Lilly's room for it. Duncan finds her in the room, and they discover several videotapes which show Lilly having an affair with Logan's father, Aaron Echolls (Harry Hamlin). Veronica concludes that when Aaron learned that Lilly had taken the tapes and she refused to return them, he killed her in a fit of rage, leading to Duncan's discovery of Lilly's body and his parents' mistaken belief that he killed her.
