John Brockbank was 25 and working as a casino dealer on the Royal Caribbean ship Azure when he disappeared on March 23, 1991, while the vessel steamed from San Pedro, California, toward Avalon on Catalina Island. He was last seen roughly five hours after the ship left San Pedro and was reported missing later that afternoon after failing to show for his shift. He was wearing a black tuxedo when last seen and had been reported to be struggling with depression.

Despite onboard searches and a continuing investigation by the Los Angeles County Sheriff’s Department, Brockbank was never found and the circumstances of his disappearance remain unclear. His case is classified as endangered missing and few details have emerged since. If anyone sailed on Azure that day or knew John, please share what you remember or contact investigators with information.
