http://www.chron.com/disp/story.mpl/metropolitan/6802967.html State set to execute convicted Dallas cop killer HUNTSVILLE A man convicted of gunning down a suburban Dallas police officer during a failed bank robbery attempt almost 13 years ago is set to receive lethal injection. Fifty-one-year-old Kenneth Mosely was condemned for the February 1997 slaying of Garland Officer David Moore. The execution Thursday evening in Huntsville would be the first of the year in the nation's busiest death penalty state. Another convicted killer is scheduled to die in Texas next week. Attorneys for Mosley say his court appeals are exhausted. A request to the Texas Board of Pardons and Paroles for clemency for Mosley also has been denied.
