In CSI: Miami, one guy has a sister who is supposed to marry the other guy, but then she gets shot and later dies. She's hot.
Also, there's a hooker in this one episode who seduces and old guy and puts some type of drug on her nipples so that he'll pass out when he puts his mouth on them, but then she absorbs it topically and crashes her jeep. In a later episode, her character is back and the guy with the hot sister nails her, but then she's murdered later that same night and he's like "omg im a suspect sorry gaiz." Anyway, she's flaming hot.
