LAGRANGE, Ga. (AP) – A west Georgia police department is seeking help solving the 15-year-old killing of a Missouri railroad contractor

LaGrange Police Detective Ley Wynne says William Kent Adams of Arcadia, Missouri, was found dead in his car in April 2003.

Adams was in Georgia working for a company that cleans railroad crossings.

The LaGrange Daily News reports an autopsy showed Adams had a gunshot wound to his chest, with officials ruling it a homicide.

Police interviewed some people but never settled on a suspect. Adams wasn’t seen on surveillance video from a nearby store.

Wynne says the case is difficult because Adams wasn’t from LaGrange, so there were no local residents to interview about friends or habits.

Anyone with information can call Troup County Crime Stoppers at 706-812-1000 or Wynne at 706-883-2609.
