A Mechanicville man has been sentenced to up a decade in prison for stealing a truck and intentionally striking a police car during a high-speed chase. Jacob R. Hayner, 38, was arrested in May after police said he stole a car from the Stewart’s Shops on Route 146 near Exit 10. WNYT reports Hayner pleaded guilty in August to grand larceny and criminal mischief and was sentenced on Monday to 3 1/3 to 10 years in prison.
