Mad River By John Sandford

Bonnie and Clyde, they thought. And what’s-his-name, the sidekick. Three teenagers with dead-end lives, and chips on their shoulders, and guns.

The first person they killed was a highway patrolman. The second was a woman during a robbery. Then, hell, why not keep on going? As their crime spree cuts a swath through rural Minnesota, some of it captured on the killers’ cell phones and sent to a local television station, Bureau of Criminal Apprehension investigator Virgil Flowers joins the growing army of cops trying to run them down. But even he doesn’t realize what’s about to happen next.
