Florida investigators are searching for a St. Louis teenager suffering from ADHD and bipolar disorder who disappeared Saturday while at the beach with her older sister, the Orlando Sentinel reported.

Nicole Crowder, 17, was last seen in the Daytona Beach area with a 30-something black man, described as bald with a medium build and wearing gold teeth, according to the newspaper. He seemed to have another teenager with him, the Sentinel reported.

Crowder, who reportedly has the mental bearing of a 9-year-old and suffers from bipolar disorder as well as attention-deficit hyperactivity disorder, or ADHD, is 5 feet, 3 inches tall, 185 pounds with brown eyes and black hair.

The Sentinel reports that she is not in possession of her medications.

Crowder was last seen around 5:30 p.m. Saturday, wearing pink sunglasses and a black-and-white one-piece bathing suit. Crowder was reported missing around 8:45 p.m. Saturday night. She had reportedly spent the day at the beach with her older, adult sister, and was visiting Windermere, Fla., to see her mother.

A check of local hospitals, hotels and businesses produced no sign of Crowder.

Anyone with information regarding Crowder's whereabouts is asked to call (386) 248-1777.
