**FILE** Convicted murderer Roger Keith Coleman waits for an interview on death row in the Greensville Correctional Center, in Jarratt, Va. in a May 20,1992 file photo. Coleman was executed on May 20, 1992. With less than two weeks left in Gov. Mark R. Warner's term, time is running out for him to arrange DNA testing that could determine whether Virginia sent an innocent man to the electric chair in 1992. If the tests show Roger Keith Coleman did not rape and murder his sister-in-law in 1981, it will mark the first time in the United States an executed person has been scientifically proved innocent, say death penalty opponents.
