Jimmy: "Investigate Joey's social relationships, communicate with his widow to find out who Joey typically saw, search the surrounding area for surveillance cameras that might have captured information, and look into cases Joey handled when he was a prosecutor. That's all I can think of for now."
Chris nodded, "You handle this case."
Jimmy closed the dossier and stared at Chris in surprise, "Huh? Why? Is it appropriate for me to take on such an important case?"
Chris: "Why do you think Hughes arranged for me to mentor you? Because I'm about to retire. Alright, you handle this case, and remember to adjust the priority of the investigative route you just mentioned."
Jimmy took a deep breath, exhaled, and nodded, "Got it, I'll first contact the police to cooperate in checking the surrounding surveillance cameras."
