[The Conversation] How the Unabomber’s unique linguistic fingerprints led to his capture

In the light of Unabomber's passing away in prison, people are reviewing how he was captured, and how linguistics played a role on this.

Linguistic analysis of his Manifesto yielded the following pieces of info:

• "rearing children" - typical for a Northern USA dialect
• "clew", "wilfully" - back then, used mostly around Chicago; so the author likely spent his formative years around the place
• "broad", "chick" - narrowing down the expected age range to middle-aged
• "anomic", "chimerical" - highly educated speaker

The article also mentions a few other cases of linguistic analysis being used to identify other people, such as JK Rowling as the Cuckoo's Nest author.
