Sentencing for a Tigerton woman is scheduled for July 6th in Portage County after her guilty plea to several charges, including homicide by intoxicated use of a vehicle.  Twenty-nine-year-old Billie Jo McSherry reached a plea deal with prosecutors in the fatal crash last summer which killed 48-year-old Robert Korhonen of Antigo and his 25-year-old daughter Stacey Zarda.  Nine charges were dropped.  Investigators said McSherry’s blood-alcohol content level was four times the legal limit when she crossed the center line on state Highway 49 and hit the motorcycle the two victims were riding.
