Forensics has always fascinated me.
While driving up to Hilton Head, I was listening to NPR, and they were talking about the manhunt for a kidnap/murder suspect. There were a few different suspects, though, and identifying the murderer was proving to be very, very difficult.
And kidnapper left a ransom note, and used the phrase "devil's strip" when telling the police where the ransom money should be left.
Well, the "devil's strip" refers to that plot of earth between the sidewalk and the street. An FBI forensic linguist read that and asked the lead investigator "Is one of your suspects from Akron, Ohio?"
The detective answered that yes, in fact, one of their suspects was from Akron. The linguist told the investigator that the person in Akron was almost certainly their suspect. The detective was stunned by this comment and asked how the linguist could be so sure.
Turns out that the phrase "devil's strip" is used only by those people who are from Akron, Ohio and from nowhere else in the country.
The suspect was arrested and gave a full confession.
I thought that was pretty fuckin' cool...
