Officers have released dash-cam video of a Nebraska sheriff's deputy risking his life to stop a runaway truck after a 12-mile pursuit. The driver was having a medical emergency, and his truck was rolling toward the Norfolk airport. When it slowed to about 25 miles per hour, Sgt. Todd Volk dashed across the highway, climbed inside and brought the vehicle safely to a stop.
