Ray Santilli is a London-based film producer, who on 5th May 1995 presented for the first time his alleged alien autopsy footage to media representatives and UFO researchers. The body was suggested to belong to one of the aliens picked from the supposed Roswell UFO crash site in 1947. The debate on whether the autopsied body may be a very realistic mannequin, a girl with a genetic disorder (namely progeria or Turner's syndrome) or a real alien is still going on. It is also questionable whether the film material and the equipments and objects in the autopsy room actually date to the time in question. Pathologists have also questioned the techniques being used in the supposed autopsy.
