CADIZ, KY-   Kentucky State Police Trooper Brian Duvall has worn the brass of the Kentucky State Police for a decade. 

He likes his job and the people, "Around this area, everybody tries to help everybody."

Scotty Gray, 47, was no exception. The UK fan always had a smile and a helping hand.

Cadiz Police Chief Hollis Alexander who knew Gray said, "He was just one of those guys that was always upbeat. Somebody you wanted to be around. A real people-person who always had a minute to talk or help you out."

And helping someone else would be his final act Monday evening.

Gray was on his way to visit family when he stopped to check on another driver who had hit a deer.  He was just a few miles outside the business district, heading east on U.S. 68 when tragedy struck.

Gray pulled up alongside the truck and then, moments later a semi came up to the scene and simply could not stop.

According to Kentucky State Police, Gray was still in his car and his seat belt still fastened  when that semi crashed into the truck, and then Gray's car.

Gray passed away at Vanderbilt Medical Center Tuesday evening.

"He stopped to help and it ultimately ended up costing him his life," Trooper Duvall said.

There were two others involved in the wreck.  Nicholas Wiseman, 20, was outside his truck, checking out the damage from hitting a deer. He was struck but listed in stable condition at Vanderbilt Hospital Wednesday evening.

The driver of the semi, Mohamed Mohamud, 50, was not injured.  KSP says toxicology tests were done on scene.  If drugs or alcohol show up in Monhamud's system, the case will be handed over to the Commonwealth's Attorney.  Criminal charges could be a possibility.
