The Windingo is a creature appearing in the mythology of the Algonquin people. It is a malevolent cannibalistic spirit into which humans could tranform, or which could possess humans.
Windingo psychosis is a culture bound disorder which involves an intense craving for human flesh and fear that one will turn into a cannibal. – Wikipedia
The murderers would often decapitate corpses and sometimes begged captors to kill them before they started eating people.
On July 20 the Edmonton Sun ran an extensive article by ethno-historian Nathan Carlson. The article featured his expertise on Windingos.
He now feels incredible guilt that his article, run in the paper that Vince Li delivered, may have contributed to the horrific death of Tim McLean, 10 days later.
"At first when I heard the news, it kind of stunned me," Carlson said.
"It was weighing very, very heavily on my mind."
Hoping to clear his conscience, Carlson contacted RCMP, advising them of the potential link between the article and the Greyhound slaying. Officers working at the Portage la Prairie RCMP station were receptive to his concerns and told Carlson they would take his information seriously.
Police are now trying to determine whether Vince Li may have acted criminally after reading about the Windingo in the newspapers he delivered.
