TOPEKA, Kan. (AP) — A Kansas official says DNA testing is so far inconclusive about whether two men executed in Kansas for the 1959 killings that inspired the book "In Cold Blood" are linked to unsolved murders in Florida. Kansas Bureau of Investigation Deputy Director Kyle Smith said Wednesday that his agency will continue DNA testing on the remains of Richard Hickock and Perry Smith. The men were hanged in 1965, for the killings of Herb Clutter, his wife and two of their children in their farmhouse outside the southwest Kansas town of Holcomb. Weeks later, Cliff Walker, his wife and their two small children were killed in their home in Osprey, Florida. Investigators say Hickock and Smith fled to Florida after the Kansas killings, and then to Las Vegas, where they were caught.
