Jimmy and Mark were drinking coffee by the roadside, waiting. After Julia returned, the three went upstairs to Oliver Morgan's apartment. Just as they were about to open the door, Jimmy reached out to stop Julia: "Put on gloves."
Mark and Julia immediately stopped, and both took out disposable gloves and put them on at the doorway. Jimmy, of course, did the same, "Open the door."
After opening the door, Jimmy and the others immediately halted. The room had already been searched over; someone had been here ahead of them.
Jimmy: "Call the forensic department over. You two wait here for them and check together. Focus on fingerprints in various places in the room; exclude Oliver's and check the rest. Also, inquire with the neighbors around to see if anyone entered this room in the past couple of days or if they've seen any strangers around."
Mark: "OK, we will keep an eye on it."
