Charles Frederick Urschel (March 7, 1890 – September 26, 1970) was an American oil business tycoon and kidnap victim of George Kelly Barnes (Machine Gun Kelly).
Urschel eventually thwarted the crime by carefully noting every piece of evidence of his whereabouts during his captivity despite being blindfolded and leaving fingerprints on every surface he could reach.
After being released after the ransom was delivered, Urschel was able to supply ample information for the FBI to solve the crime.
