who was the killer in the perfect getaway
A Perfect Getaway Flashbacks reveal that Cliff and Cydney are drug-addicted sociopaths who murdered the newlyweds. They kill people and steal their identities in order to, as Cliff explains, "live a hundred different lives and achieve a kind of immortality". It is also revealed that "Cliff" had planted the bag of teeth in Kale and Cleo's bag to frame them for the murders.
