Charges are expected to be filed today against a Columbus woman who Pickerington police say killed a motorcyclist in a crash last year. Investigators say tips from the public led them to the 24-year-old unnamed woman. Police say she confessed to hitting and killing Gayle Jackowski on I-70. The unnamed woman claims she was changing lanes when she hit Jackowski and sped off in a panic. Police say her father helped her destroy the car.
