Sheena Dayle Johnson was 21 when she was last seen on the afternoon of September 8, 2006, in Jacksonville, Florida. She walked from her family home on Mackinaw Street to the nearby McDuff Food Mart to buy a cigar, spoke with her mother and said she would be home shortly, but never returned. Her family reported her missing three days later on September 11 after her cell phone was found turned off, which they say was out of character for her.

At the time she disappeared Johnson was unemployed and, according to her family, had no known enemies or history of mental illness. Initially law enforcement did not suspect foul play, but after an extended period without contact authorities began to consider that possibility. The case remains unsolved.

If anyone in Jacksonville remembers seeing Sheena on September 8, 2006, or has information about her movements that afternoon, please come forward.
