Summary based on 4 sources
Sandra Jean Binns, a 39-year-old woman, vanished from Big Pine Key, Florida, on December 9, 1991. She has not been seen or heard from since, and the circumstances surrounding her disappearance remain largely unknown.

Binns is described as a white female with brown hair and brown eyes. At the time she went missing, she was 5'3" tall and weighed approximately 130 pounds. A notable distinguishing feature is a scar on her knee.

The Monroe County Sheriff's Office is the investigating agency for her case. However, there is a distinct lack of detailed information available to the public regarding her disappearance. Online sources and official databases offer few specifics about what she was doing on the day she was last seen, who might have been with her, or any potential leads in the investigation.

Despite the passage of time, her case remains open. Information has been shared through resources for missing persons such as The Charley Project and the Doe Network in the hope of generating new leads. The lack of public information makes it a challenging case for both law enforcement and her family.
