Christopher Patterson was 18 when he was shot and later died on May 4, 2016, after an early-morning attack on Iowa Street near Long Avenue in Savannah, Georgia. Officers were called just before 1:00 a.m. and found Patterson wounded by gunfire; he was taken to Memorial University Medical Center but did not survive. Investigators said he had been walking on Iowa Street when the shots were fired and from the beginning they did not believe the attack was random.

Police released only limited details while saying they were following leads, and funeral notices show services in Savannah on May 14. Authorities publicly identified Joshua Brooker, 17, as someone they wanted to question and later reported making contact with him; that update did not say he had been arrested or charged.

Does anyone have information about Patterson’s movements that night or about witnesses who might have seen what happened?
