It took nearly 20 years for authorities in Brooklyn to get a conviction in a 1991 homicide where a young man was shot in the face with a .380 caliber bullet, but a panel decision Wednesday put prosecutors back at the start of a case that’s already been tried twice.

In a 3-1 decision, the Appellate Division, Second Department, reversed Derrick Lloyd’s second-degree murder conviction in the interests of justice and granted a new trial to a defendant who was on the lam until 2007, when he was caught in Alabama attempting to obtain a driver’s license under a fake name.
