Tony and Kate stepped into the room, only just holding onto each other's hand.
"We found this in a box under his bed." He showed them a tape, with a dusted fingerprint on it.
They looked at Kate for some clarification.
"M-my brother used to hide thing he wanted to keep secret in that box." She said, looking shocked.
"How did he know?" She asked herself, slightly under her breath.
"The same way he knew about all the other vics." Tony pointed out thoughtlessly. Not seeing how scared Kate was by this thought.
"Did you do that?" Tony said gesturing to the dusted print on the tape surface.
"No, it was like that when we found it." He said honestly.
"Oh my God, he did that himself?" Kate asked for confirmation.
"Guess so." The officer replied.
Tony took the tape from him by the tips and handed it to a forensic investigator, who accepted it with a nod, and began to remove the print.
