Summary based on the NamUs case record (MP23979) and 7 other sources
JoAnn Benner, a 21-year-old mother of two, disappeared from her home in Bayou George, Florida, on May 14, 1976. Her husband, Gary Benner, claimed she left in the middle of the night and never returned. However, the circumstances surrounding her disappearance raised immediate suspicion, particularly because of conflicting evidence and strange behavior exhibited by her husband. Shortly after JoAnn's disappearance, her three-year-old daughter told a relative that her mother had been bleeding from the stomach, which added to the mystery and concern.

Upon investigation, authorities discovered blood stains in the Benner home, as well as sections of carpeting that had been removed. The carpet was later found burned in a trash can. Although Gary Benner claimed the blood was from a domestic argument, his story lacked credibility. Shortly after JoAnn vanished, Gary was seen returning home with mud on his clothes and vehicle, leading investigators to believe he may have disposed of her body. Despite these suspicions, no charges were ever filed against him due to insufficient evidence, and the case remains unsolved.

Over the years, advances in forensic technology were applied to the case, but efforts to test the collected blood evidence were hampered by degradation over time. The case grew colder as no new leads emerged. JoAnn Benner's disappearance remains a tragic mystery, with her family still seeking answers decades later.
