PREVIOUS STORY: Police are searching for the driver of a truck involved in an apparent road rage incident that turned violent in Hixson Friday morning leaving one man in the hospital. 

Channel 3 spoke with one man who heard the situation unfold. He asked us not to reveal his identity. 

"It sounded like road rage going on because you heard brakes and then you heard taking off and spinning tires and taking off," he said. 

Witnesses believe the altercation started on Dayton Boulevard and then escalated when both drivers turned onto Dowlen Road. 

"Somebody started yelling and then I heard somebody else yelling but it was indistinct. You couldn't make out what they were saying and then pop!" the witness added. 

Chattanooga Police say Cletus Harvey, 66, told investigators he approached the driver of a black truck for following too close when the driver took out a gun and shot Harvey before driving off. 

Witnesses say Harvey made his way to the intersection looking for help when good Samaritans stepped in. 

"The nurses had opened his shirt and I saw the wound, it was on the right side of his chest right below his pec," he said. 

Harvey was taken to the hospital where he is expected to be okay. 

Now police shift their focus on the search for the person they say is responsible. 

Witnesses we spoke with want to know why the driver took off. 

"If he feels that justified enough to shoot somebody, brave enough to shoot somebody, why don't you stand up and say you did it?"

Police are on the lookout for a black GMC or Chevy truck with Tennessee tag number 357-WGF.

If you see this truck or have any information, call police immediately at 423-698-2525.
