It seems like Shinji-san is positive Nanaka didn't kniw anything based on her intellect and he won't do anything to jeopardize the case or the killer..........my suspicion of Shinji being a nuscience at the time of the killer's capture and interrogation has dropped to about 5% yet nobody knows his true intentions and thoughts on the matter
