 FACT: Nigel says that the coffee found on the body is Colombian  Sumatra. This would have to be a blend of coffee instead of a  specific bean. Sumatra is a place coffee is grown as is Colombia.  Coffee beans are either Arabica or Robusta.  Note: This could be a Sumatran variety transplanted to and grown in  Colombia. The number of coffee varieties has been increased over the  years, even if in name only.
