John Brockbank, a 25-year-old casino dealer on the Royal Caribbean Cruise Lines ship *Azure*, went missing on March 23, 1991, while the ship was en route from San Pedro, California, to Avalon on Catalina Island. Brockbank was last seen about five hours after the ship left San Pedro, and he was reported missing later that afternoon when he failed to show up for his work shift. Despite efforts to locate him, he was never heard from again.
At the time of his disappearance, Brockbank was reportedly struggling with depression. He was last seen wearing a black tuxedo. The circumstances of his disappearance remain unclear, and few details have emerged since. His case is classified as endangered missing, and investigators have not been able to determine what happened to him after he was last seen aboard the ship.
The Los Angeles County Sheriff's Department continues to investigate the case, but no significant leads have surfaced over the years.
Last Seen: Mar 23, 1991
