Summary based on the NamUs case record (MP59138) and 7 other sources
Theresa Hickmon, a 20-year-old woman, disappeared from Jacksonville, Florida, on December 1, 1984. She was last seen boarding a boat named *Sea Fever*, a 42 or 46-foot 1960 Richardson, along with her friend Angela Westberry and two unidentified men. The group was supposedly heading for a vacation in the Bahamas. However, after leaving Jacksonville, they were never seen again. The *Sea Fever* was last sighted by U.S. Customs on December 14, 1984, near the Grand Cayman Islands, but the fate of its passengers remains a mystery.

The disappearance of both Hickmon and Westberry has led to various theories, ranging from a possible sinking of the vessel to foul play involving the two men who accompanied them. Despite ongoing efforts, no trace of the boat or the missing individuals has been found. Hickmon’s case is classified as endangered missing, and authorities suspect foul play. Investigators and family members are still seeking information that might lead to uncovering what happened to Theresa and the others aboard the *Sea Fever*.

The Jacksonville Sheriff’s Office continues to investigate this decades-old case.
