Metro Transit Police Officer Jason Williams testified in D.C. Superior Court earlier this month that he had arrested Anthony Morris, 47, at the Petworth Metro station on Jan. 31 for possession of cocaine and heroin. In the court hearing, Williams confirmed that the defendant in the case was the same man he’d arrested. Defense attorney Dehlia Umunna took issue with the ID. “This is not my client,” said Umunna. She was right: The marshals, it turned out, had brought out the wrong defendant, Antowine Moore, prompting D.C. Superior Court Commissioner Judith Macaluso to dismiss the case. According to Umunna, Moore, a well-built 32-year-old with short hair, looks nothing like Morris, a lanky fellow with a Don King-like black-and-gray crown. Morris didn’t go free but to a halfway house to await trial in another case. The government decided not to prosecute Moore, who was also facing drug-possession charges. As for the bad identification, the government shrugs it off. “That’s why we have trials,” says Channing Phillips, a spokesperson for the U.S. Attorney’s Office. “Mistakes happen.” —Annys Shin
