So the person interviewed is a linguist who's colleagues "helped crack the Unabomber case by analyzing Ted Kaczynski's 35,000 word manifesto."
So the Washington Post published the Unabomber's 35,000 word manifesto in it's daily paper in 1995 as a special section. The Unabomber's brother recognized and turned in his brother. There was no crack in the case by investigators. His brother received the $1 million dollar reward from the Department of Justice for turning him in.
This isn't fake news but it is incorrect. Linguistic experts were involved but it doesn't go much deeper than that.
