Angela Joann DeLawder was 20 when she vanished from Hallandale, Florida, on March 7, 1981. She was last seen that evening with her live-in boyfriend Ivan Gutierrez, her mother Gertrude Menacher, and Menacher’s boyfriend Charles Gibson. All four disappeared after meeting for a dinner engagement and none have been found.

Several details in the case have been described as suspicious. Gibson’s Cadillac was recovered abandoned at Miami International Airport soon after the group vanished, and Gibson reportedly cleared out his apartment before disappearing. Menacher and Gibson were sought for questioning in the murder of a drug enforcer, Harvey McElroy, and investigators have suggested Menacher and Gibson may have been killed because of what they knew. Angela and Ivan have been considered possibly innocent bystanders, though an alternative theory is that the four fled, perhaps to another country.

No substantial evidence has emerged to resolve what happened to Angela and the others. If anyone knew Angela, her movements, or the people she was last with, can you share information that might help clarify this disappearance?
