On May 23, 2004, 46-year-old Vincent Paul Petrilena, known as Vinnie, went for a swim from a houseboat near Grebe Bay on the Arizona side of Lake Mead’s Virgin Basin and never returned. Strong, sudden winds swept the houseboat away from him while he was in the water; a person aboard put on a life jacket and jumped in with a spare but could not reach him because of the distance created by the wind. Extensive searches were conducted, but the area where he vanished reaches depths of about 180 feet and his body was never recovered.

Authorities have presumed he drowned given the circumstances and lack of any further sightings, but no recovery has been made and the family has no final closure. Does anyone have information about that day at Grebe Bay or about Vinnie’s activities before he entered the water?
