Robert Louis Arcaris was 36 when he vanished from the Las Vegas area after going boating on Lake Mead on October 12, 1987. He has not been seen or heard from since. He is described as a white male, 5 feet 10 inches, about 140 pounds, with brown hair and hazel eyes and scars on his forehead, right cheek, and near his right eye.

Arcaris reportedly used several aliases, including Robert Lee Harrison, Robert Lyons, Louis Robert Meyers, and Louis Myers. The official report notes he had no vehicle available the day he disappeared. Some investigators have raised the possibility his disappearance is connected to a homicide near Lake Mead around the same time, but no evidence has been made public to confirm that theory.

Does anyone have information about Arcaris, his movements in October 1987, or contacts who might know more about his aliases?
