Tatyana Smirnov, 29, a systems programmer from Framingham who worked for Fidelity Investments, disappeared while on a scuba diving trip in the Florida Keys on November 9, 2003. She was described as a white female with black hair and black eyes, between 5 feet 4 inches and 5 feet 8 inches tall, weighing 136 to 150 pounds, with a history of fractures in her left arm, an appendectomy scar, and a small scar on her upper right thigh.

That afternoon she was on a dozen-person excursion aboard the Tropic Vista to Cocker Reef, off the southwestern tip of Key Largo. While swimming about 40 feet down with her dive partner, the partner reported getting slightly ahead, turning back, and finding Smirnov gone. Her partner was later rescued by the Coast Guard in good condition. Thirteen days after the disappearance a lobster fisherman found her scuba equipment off Islamorada; the gear was positively identified by her husband, but Smirnov herself has never been found and is presumed lost at sea.

Did anyone dive or fish around Cocker Reef on November 9 who might recall seeing the Tropic Vista or remember unusual activity that afternoon?
