The evidence he got was little, but he was fully aware of what happened, so he took notes of the whole incident and went to the bedroom.
Studying the bedroom, he noticed a cell phone on the bed, so he took it, and it wasn't with a password, thus explaining the carefree nature of the man. He smile at his discoveries over once more before he took the phone and pocketed it for further examination. He returned home and surveyed another part of the apartment and could find nothing.
Moving back to the living room, he noticed a space opposite the entrance, which he didn't possibly see the first time, and he went to the room.
It was empty with only a chair and a table. He was about to get disinterested in the room when he noticed the ceilings were open, which was quite unusual, but he waved it off, saying Jerry may have wished for his shelters to be opened in the room.
