Fool Me Twice (S01E12)

A man is brutally shot and seemingly left for dead, with a kilo of tainted heroin discovered in his vehicle. Antonio investigates and uncovers a pattern of other murder victims linked to the same type of adulterated drugs. As he digs deeper, it becomes clear that the narcotics detectives on the case, including one with a commendable record, are somehow connected. Meanwhile, Stone is reluctant to allow Nagel to participate in the investigation due to her personal ties to the victim, complicating matters further.
