A Cashton teenager was injured as a result of a one-vehicle rollover crash Sunday morning.  Vernon County Sheriff John Spears said, “About 5:35am 17-year old Austin Hooker was traveling north on Highway 27 near Westby when he lost control while rounding a curve.  The vehicle crossed the center line and struck a mailbox.  It overturned several times before coming to rest in the ditch.  The airbags deployed but Hooker was medically transported to Gundersen Health Systems in La Crosse.”
