The State Patrol has released the names of a woman and child injured when their car hit a snowplow Wednesday afternoon in Rochester. Investigators say 25-year-old Heidi Therkilsen was driving north on Highway 52 when her vehicle collided with a plow clearing snow from the right shoulder. Therkilsen and her one-year-old son were taken to a Rochester hospital with non-life-threating injuries. The plow driver was not hurt.
