Police in Georgia are looking for a retired couple who went missing after responding to a Craigslist ad for a vintage car.
Elrey Bud Runion, 69, and his wife June, 66, were last seen Thursday when they left to buy a 1966 Mustang they found on Craigslist. Police say the number attached to the ad was traced to a disposable cell phone. They were supposed to return that night.
The Runion's cell phone data shows they made it to McRae Thursday evening but that's where the trail ends for investigators. The search now involves numerous counties in Georgia.
"We did have reason to believe that they traveled to this part of the state. We began searching with deputies who are on duty and some of the neighboring counties."
Family members say classic cars are Bud's passion and one of his very first cars was a '66 Mustang. They became alarmed when Bud and June didn't respond to texts or return their calls on Friday.
Their daughter, Virginia Owens, told WGCL Bud was especially careful when meeting strangers.
"He would have certain protocols and security measures he would follow. He would always say meet someone in a very lit parking lot. Dad was the type to think of the 'if-then' situations and 'if this happened then this is what you need to do.'"
A Facebook page has been set up to help find the couple. Anyone with any information about the couple is asked to call the Telfair County Sheriff's Office at (229) 868-6621 or the Cobb County Police Department at (770) 499-3945.
