Gabriel Vincent
Missing since November 1979 from Las Vegas, Nevada
Classification: Endangered Missing

Circumstances of Disappearance
Gabriel Vincent rented property from David Dale Morgan, a millionaire Las Vegas landowner. Vincent rented a storage facility from Morgan at 3200 W. Teco Avenue. Vincent went missing near the end of 1979. In February 1980, Morgan's wife, Marie, vanished. There was talk that Vincent and Marie Morgan had been having an affair. Detectives suspected Marie Morgan met a violent end. She was reported missing not by her husband, but by an employee of the Women's Crisis Center.
Marie Morgan was never found, but after her disappearance, David Morgan said she ran away with Vincent and accused her of infidelity.
In 2000, 36-year-old Diana Leone, David Morgan's live-in girlfriend since 1986 and mother of his two children, disappeared after he had been arrested several times on charges of beating her.
In early 2006, detectives found a former employee who reportedly was present when Vincent was shot and was said to have helped dispose of Vincent's body. He told police that David Morgan had killed Vincent and buried his body near Indian Springs in November 1979. Authorities suspect that Vincent's body later was dug up and brought back to property owned by David Morgan off Sunset.
On January 2nd, 2007 United States Marshals and Arizona Police Officers arrested David Morgan on one count of first degree murder in Kingman Arizona, based on a homicide warrant prepared by the L.V.M.P.D. Missing Persons Detail. Morgan was arrested for the murder of Gabriel Vincent.
