Md. man convicted of conspiring to kill federal witness A 33-year-old Maryland man was found guilty Thursday of conspiring to a kill a witness against him in a federal drug prosecution. It took a jury in the District's federal court two days to reach a verdict after the two-week trial of Weldon Gordon on charges of conspiring to obstruct justice by tampering with a witness and tampering with a witness by killing, as well as drug distribution. Prosecutors have said that Gordon, of Largo, directed his girlfriend to befriend the witness, Andre Hayes, 32. She then lured Hayes to a house in Upper Marlboro, where Gordon shot and killed him early on Nov. 1, 2008. At the time, Hayes was the key informant in a Drug Enforcement Administration investigation that led to federal narcotics distribution charges being filed against Gordon in the District. The girlfriend, Tiffany Reaves, who pleaded guilty last year to tampering with a witness, testified for the prosecution at Gordon's trial, court records show. Gordon's attorney, Thomas J. Saunders, said he planned to appeal the verdict but declined to comment further. Gordon is scheduled to be sentenced May 17 by U.S. District Judge Ricardo M. Urbina, who presided over the trial. Assistant U.S. Attorneys Darlene M. Soltys and Emory V. Cole declined to comment after the verdict. In June, a federal grand jury indicted Gordon's mother, Vicki, 51, and his sister, Keyla Clements, 35, and her husband, Antoine Clements, 38, on charges that they lied to grand jurors by providing a false alibi for Gordon. They have pleaded not guilty.
