John Urbain Vallandry, 20, was found dead on July 10, 1974, with a fatal bullet wound to the head on the side of State Road 581. He had been driving his girlfriend’s car; that vehicle was later located abandoned at Gene’s Lobster House in Madeira Beach. Both Vallandry and his girlfriend were reported to have been involved in marijuana trafficking.

Vallandry’s homicide was one of several unsolved killings in Pasco County and the Tampa Bay area during the 1970s. Investigators examined whether his death was connected to a string of violent crimes attributed to a suspected offender dubbed the Gulf Killer, who was suspected in multiple murders between 1971 and 1978, but authorities were unable to establish a clear link. No arrests were made in Vallandry’s case and it remained unsolved.

Did anyone who knew Vallandry, his girlfriend, or their movements in mid-1974 ever see the car at Gene’s Lobster House or notice anything unusual on or near State Road 581 that summer?
