A Smith County deputy was injured this afternoon when his patrol unit was hit by a pick-up. Sheriff J.B. Smith says deputy Mike Lunsford was headed to a routine call when the pick-up turned a corner and ran into Lunsford's car on Morningside Drive. The three men inside the truck ran into a wooded area. A search of that area led deputies to a home where they believe one of the suspects may live. Though no one was home, investigators believe they know the identity of the suspects. Deputy Lunsford was taken to Mother Frances Hospital with head and back injuries. Sheriff Smith says those injuries are not life threatening.
