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.
