Robert Arthur Wiles, 26, was last seen on April 1, 2008, at Lakeland-Linder Regional Airport in Lakeland, Florida, where he worked as a business development manager for his family’s aircraft maintenance company, National Flight Services. Two days later his family received a ransom note demanding $750,000. The family followed the instructions and left the money, but no one came to collect it and Wiles was never heard from again.

Wiles was described as athletic and adventurous, with a passion for flying, diving and fishing, and extensive work travel domestically and abroad. A lengthy investigation followed; although a former co-worker, Stobert Toby Holt, was later arrested and convicted in connection with the case, Wiles’s body has never been found and he is presumed dead. Foul play is strongly suspected because of the ransom demand and the conviction tied to the disappearance.

Does anyone who knew Robert or worked at Lakeland-Linder Regional Airport in 2008 have information that might clarify what happened that April?
