(AP) — Elrey "Bud" Runion posted an ad on Craigslist seeking to buy a piece of his youth, a replica of the 1966 Ford Mustang convertible he bought after returning from the Vietnam War decades ago. Ronnie Adrian "Jay" Towns, 28, of McRae, was accused Tuesday of killing the Runions, a couple from Marietta, Georgia, who were known for their charitable works throughout the South: from storm-damaged Alabama towns and impoverished pockets of West Virginia to housing projects in the Atlanta suburbs. Someone tied flowers to a child's bicycle and left it standing below a flag flying at half-staff in the couple's front yard in Marietta, three hours north of McRae. The suspect, Towns, was charged Tuesday with malice murder and armed robbery. Telfair County Sheriff Chris Steverson said robbery appears to be the motive for the couple's killings, but he would not say whether the Runions were carrying cash or disclose other details about the case. On Monday, he said investigators had found no evidence that Towns owned the sort of classic car Runion was seeking. The Runions' slaying shocked residents of McRae, a tiny city about 80 miles southeast of Macon, where a public mural in the downtown square proclaims it's the "6th Safest City in Georgia." Towns grew up on a farm down a long dirt road where his father raised pine trees and grew soybeans, corn and peanuts.
