CSI girl can fly

This episode was about a girl who was thrown out of her window. The suspect, Marlin, had killed before, but his sister made it seem as though she was the one who killed her. His sister is a genius; she went to harvard and then went to grad school. She is VERY smart. This episode was very exciting because at the end, we find out that it was actually the little sister who killed the girl. The little girl is very manipulative and she changes the evidence to make it seem as though it was the brother who killed the girl. It was a very interesting episode...
