An investigation begins, and when Patrick recognizes a link between a recent murder the team was investigating and Red John, the team hurriedly arrives at the workplace of the victim - and find the third member of Bosco's team dead, murdered by Red John. With Red John revealed as being behind the attack, it is found to have been orchestrated as Bosco had come close to finding the infamous serial killer while investigating the discovery of the missing body of a Red John victim; the body had been removed and hidden due to forensic evidence left by Red John himself.

It is found that the person who recovered the evidence was Bosco's secretary, Rebecca, who was also the assailant who shot Bosco and his team. Lisbon arrives at Bosco's hospital room to apprehend her just before she finishes him off. Before Bosco dies, he declares his love to Lisbon and wishes Patrick luck in finding Red John. Rebecca is later poisoned by Red John before entering her jail cell after being interrogated by Patrick.
