He died of complications from a heart valve replacement surgery, said Craig Emmick, a director at Columbia Funeral Home in Seattle.
Wilson was convicted in 1983 for shipping 20 tons of C-4 plastic explosives to Libya. At trial, he said he did it to ingratiate himself with the Libyan government at the CIA’s request, The Associated Press reported.
His conviction was overturned by a federal judge in 2003. The judge said the government failed to correct information about Wilson’s service to the CIA that it admitted internally was false.
He served 22 years in prison until he was released in 2004. He then moved to Edmonds, Wash., north of Seattle, to live with his brother.
