Mushrooms

S1, E17: A baby has been killed and his twelve-year-old brother Gregory has been shot. Detectives Greevey and Logan believe that there must be a connection with the older brother and drugs. Returning to the scene of the crime, they find a gun in the boy's room, meant supposedly for protection. Tonel Otten, who was outside at the time of the shooting, gives Logan and Greevey a tip that leads them directly to a disturbing cartel of child gangsters and drug dealers.
