The goof item below may give away important plot points.
Jessica('Leah Pipes' qv) puts the blame on Cassidy ('Briana Evigan' qv) for being responsible of the murder alone when Cassidy insists on calling police. She wraps the body in Cassidy's jacket to make sure Cassidy gets framed if the body is found. However, she leaves a significant evidence by throwing the murder weapon with bare hands, leaving her and Garret's fingerprints on it with the dead body. This would make Jessica's story suspicious if Cassidy tells police the real story.
