Need a lawyer over a stolen Marketplace bike

My kid brother thought he scored a deal on a used motorcycle through Facebook Marketplace. He met the seller in a grocery store parking lot, paid cash, and came home with a handwritten bill of sale and a title that looked real to him. Two weeks later the police ran the plate, the bike came back stolen, and now they're treating him like he knew exactly what he was buying. He still has the entire message thread, but the seller's profile has disappeared. Where do we find a criminal attorney in New York who won't treat this like some generic theft case?
