Police in Southern California, who sought reality show contestant Ryan Jenkins in connection with the murder and mutilation of his ex-wife, have still not located the late model’s missing Mercedes-Benz — which authorities believe could help their investigation.

The body of 28-year-old Jasmine Fiore, a former model, was found stuffed inside a suitcase and thrown in a trash bin on Aug. 5. Her fingers and teeth were missing. Jenkins, who appeared on VH1’s Megan Wants a Millionaire and I Love Money 3, was found dead Sunday in a motel room in his native Canada. He had been the subject of an international manhunt for nearly a week.

The car is part of a “big unsolved puzzle” as Buena Park Police try to determine where Fiore was killed, Sgt. William Kohanek said Monday.

The missing car is a white 2007 Mercedes-Benz CL S550 with a black top and black rims.
