Rare Blood Sect

He soon realizes that this murder is just one of a several of murders in the city and surrounding areas, and it appears the murders are related: each of the victims had the exact same rare blood type. Can Robb and his team of detectives, CSI agents, pathologists, and, eventually, the FBI solve the crimes before anyone else is targeted and falls victim to the Rare Blood Sect?
