Who's Killing the Shopkeepers?

Mohamed Gebeli, 65, is found dead with a single gunshot wound to the neck in his Bay Ridge clothing store. Detectives First Grade, Luis Yero and Michael O'Brien are called to investigate the murder. They can't find any motive and wonder if it's a racially motivated hate crime. There is little evidence to work with until police discover other shop owners in the area are also being targeted and piece together a bizarre case of vengeance.
