"He probably anticipated that we didn't have much evidence on him. When we took him to the interrogation room, he looked indifferent and even resisted our questioning."
Upon hearing this, Mr. Ma paused for a moment.
This wasn't the first time he'd encountered such a killer.
In his younger days, he'd often faced situations where breakthroughs were made solely through confessions with little evidence.
After a long silence, he said deeply, "Mr. Li, in the investigation of cases, we need to broaden our thinking. Besides the traditional physical evidence deducing and forming a closed loop of evidence, shouldn't you consider other avenues?"
"Other avenues?"
Li Jian wanted to ask what these avenues were, but Mr. Ma suddenly said, "I have to leave for a meeting!"
Then, there was a busy tone from the other end of the phone.
After hanging up, Li Jian frowned: "Mr. Ma asked us to consider other possibilities, but where do we start?"
