The death of Akai Gurley is notably similar to the shooting death of Timothy Stansbury Jr. that occurred in January 2004, when Officer Richard S. Neri killed Timothy Stansbury Jr., 19, on a roof at the Louis Armstrong Houses in Brooklyn at about 1 a.m. when Officer Neri, with his gun drawn, approached a rooftop door to check the stairway inside. A grand jury declined to indict Officer Neri on charges of criminally negligent homicide, declaring the event an accident, after he gave testimony that he had unintentionally fired; he was startled, he said, when Mr. Stansbury pushed open a rooftop door in a place where drug dealing was rampant.
