Wiles was last seen at Lakeland Linder Regional Airport where he worked for his family's airplane maintenance company as a business development manager and pilot. CNN reports:

Co-workers at the Florida airport facility said they're baffled by the kidnapping. They said they can't think of a reason for kidnapping the young man.

His mother, Pam Wiles, said there is "no way" her son was involved in anything illegal.

His friends and family said Wiles wouldn't simply run away. They also said Wiles, who is not married, would never abandon his family.

According to the FBI, Robert Wiles is a pilot who flies company planes to meetings throughout the U.S. and Caribbean. According to public records, the Wiles family business had $8.5 million in sales last year and has 105 employees.

Robert Wiles is 5 feet 9 inches tall, weighs 165 pounds, and has hazel eyes and brown hair. Any one who believes they have seen him should contact the Tampa FBI office at 813.253.1000.
