The district attorney Friday said a re-investigation of the murder of the Rev. Martin Luther King Jr. found no evidence anyone other than James Earl Ray committed the crime.

"There is simply no credible evidence to support a new trial for Mr. Ray," Bill Gibbons said. "The evidence against him is overwhelming."Gibbons' probe began last year after King's widow, Coretta Scott King, and son Dexter said Ray should receive a trial to clear up lingering suspicions of a conspiracy in the April 4, 1968, assassination in Memphis.
