Summary based on the NamUs case record (MP11428) and 8 other sources
Rosemary Day, a 27-year-old woman, was last seen on May 21, 2011, in Jacksonville, Florida, where she resided in an apartment in the Ortega Woods Drive area. Rosemary, who was known for her quiet and sweet nature, disappeared under concerning circumstances, as she left without her daily medication for depression, which raised worries about her well-being. Her family later revealed she had been in an abusive relationship and feared for her safety at the time of her disappearance.

Rosemary was driving a blue 2003 Toyota Corolla, which was found abandoned over two months later in downtown Jacksonville. The car had been parked long enough to accumulate cobwebs, and inside, investigators discovered clues, though they did not disclose specific details. Despite extensive searches and public appeals, including billboards and flyers, Rosemary’s case remains unsolved. Her family continues to hope for answers, as her disappearance remains an enduring mystery.
