Abstract: The jaw supporting device for use on a deceased person is a one-piece, U-shaped jaw rest for resting against and gripping around the front of the neck of the deceased person. The U-shaped element has a curved portion at the bottom of the U-shape, with the curved portion having an upper side and a lower side. A jaw rest portion is formed at the upper side of the curved portion for engaging and supporting the jaw of the deceased person when the U-shaped element is positioned against the front of the neck of the deceased person. A chest or collar engaging portion can be formed at the lower side of the curved portion for engaging against the chest or collar bone when the U-shaped element is positioned against the front of the neck of the deceased person.
