Floater (S14E07)

A floater is found in the Hudson, and with the body so badly decomposed it's very difficult to make an identification. After an exhaustive search of the west side, Briscoe and Green find a locket in Ft. Tyron Park and inside is a photo of a girl in a school uniform. They track the girl, Lena Marchetti, and discover her mother, Arianna, is missing. Arianna is the victim and the Detectives question her father, Gene. Apparently, Arianna went to the corner store and disappeared, but a witness claims to have seen her getting into a black sedan. The Detectives question Gene, who says his marriage was perfect and there wasn't a third party involved. But Gene's ex-wife gives a different idea, claiming he cheated on her with his personal assistant, Arianna. They get the feeling Gene's current assistant is sleeping with him as well, and also happens to be his alibi. (iTunes)
