Continuity mistake: In the hotel lobby, the chair that Leland knocks over switches between shots between lying on its side and on its back.
Continuity mistake: After Leland is pulled over by the police, he goes to open the boot of his car, and he is wearing dark gloves. When he rummages in his golf bag containing the body for a golf club, he is wearing no gloves. Then he holds the club in the air to show Cooper and the gloves are back again.
Continuity mistake: The amount and pattern of the golf balls on the Palmers' living room floor changes between shots.
Chosen answer: Laura was killed by her father Leland, whilst he was apparently possessed by the spirit BOB. The exact manner of her murder is not clear, as several injuries found during her autopsy we later discover occurred during a separate incident before her murder. We know that she was beaten and killed in an abandoned train car, and her body was then wrapped in plastic and thrown in the river.
