Jimmy watched as Nia left the meeting room and said to Chuck, "Detective Chuck, this case might still need to be handled separately. The anonymous call you guys filtered out just now may not be related to Diego's death, but it's probably connected to what was found in his house. If we later confirm that the shooter was one of his surgery clients, then this lead about the stuff found in his house might have to be handed over to the DEA."
Chuck was noncommittal; the evidence had already been brought back to the station. The police had the authority to handle drug dealers on their own, it was just a matter of spending some manpower to identify who was picking up the goods. This achievement, however, giving it up straight to the DEA, would feel a bit painful. Achievements were one thing, but the involved evidence and seized items often became one source of their office's operating funds. (This point won't be elaborated on, as each police station has its little treasury.)
