Police are seeking help from amateur sleuths - after a man was found dead with an 'unsolvable' code hidden on his body. 41-year-old Ricky McCormick badly decomposed remains were discovered in an abandoned cornfield in St. Louis, Missouri, US in 1999.
An autopsy couldn't determine the cause of death - and cops failed to establish any motive for his death. All they had to go on was two scraps of paper in his trouser pockets, with encrypted code scrawled on them.
Experts from the FBI spent over a decade trying to decipher the code, before releasing them to the public, hoping someone would be able to help them unravel the mystery. When the FBI released all the details of the case, cryptology specialist Dan Olson explained: "We are really good at what we do, but we could use some help with this one.
"Breaking the code could reveal the victim’s whereabouts before his death and could lead to the solution of a homicide. Not every cipher we get arrives at our door under those circumstances.”
