Beloved fashion accessory becomes city evidence, as DNA taken from a suspect matches hair found in a do-rag left at a 2002 murder scene. Sixteen year-old DeJuan Brown apparently shot a correction officer and an innocent bystander outside a liquor store in Bedford-Stuyvesant, and left the gun and his do-rag at the scene.
A less gritty version of this crime would make a great Encyclopedia Brown mystery: Bugs Meaney would have dropped his do-rag outside the ice cream parlor whose gallons of peppermint stick ice cream are missing. Encyclopedia and Sally would trace it to him because only Bugs Meaney would wear a Miami Dolphins do rag. Or something. The Modern Humorist has the brilliant Encyclopedia Brown Complete Casebook.
