A Melcher-Dallas resident was transported by Mercy One helicopter to Des Moines Thursday afternoon after her car rolled over, pinning her. Knoxville Fire Department Chief Mike Roberts says the resident’s injuries didn’t appear to be life-threatening, but because she was pinned she was transported to Des Moines. Knoxville Fire and Rescue, Knoxville Township Fire Department, Marion County Sheriff’s Deputies and Marion County Emergency Management all responded to the scene.
