More than a month ago, Marion police sergeant Darrell Prewitt became the victim of a high-speed collision on Interstate 40. The impact left his left leg hanging on by just a muscle. These days, however, he's back on two healthy legs, after being taken to the Regional Medical Center at Memphis and undergoing six surgeries. Today, health care reporter Steve Bohnel joins us to talk about this story.
