In November 1981, Wood's life was tragically cut short during a Thanksgiving weekend boat trip near California's Catalina Island. Accompanied by Wagner, her Brainstorm co-star Christopher Walken, and skipper Dennis Davern aboard their yacht Splendour, Wood drowned under circumstances that have fueled speculation for decades. Initially ruled an accidental drowning, the case took a dramatic turn in 2011 when Davern revealed he had withheld information about a fight between Wood and Wagner shortly before her death. His claims prompted authorities to reopen the investigation.
Over the years, investigators received more than 100 tips, and Wagner was named a “person of interest.” However, in 2022, the Los Angeles County Sheriff's Department announced that Wagner had been cleared of involvement, stating that all leads in the case had been exhausted. Despite this, Wood’s death remains officially unsolved. Authorities remain open to new leads, ready to revisit the case if fresh evidence comes to light.
