Veronica found out that the cameras in the pool house had been set up by Logan's father, Aaron Echolls, and discovered that he was the one who killed Lilly after she stole the tapes he made of them having sex. The night Aaron was arrested for Lilly's murder, Logan turned up at Veronica's house, after having been severely beaten by the PCHers. Veronica stood by him when he was accused of murdering one of them, Felix Toombs. Though he was acquitted, Logan's behavior became erratic over that summer, because of his trial and because of the revelation that his father had been having an affair with Lilly and had killed her.
