Just when Zhao Yu saw it in horror, the video secretly captured by the surveillance camera was still going on. Han Kuan was seen standing outside the toilet partition and showing something strange, but he quickly recovered in less than two seconds. .
At that time, he seemed to realize something and hurried back to the urinal. Then he looked around suspiciously and almost saw the camera Zeng Ke had installed.
Fortunately, at the critical moment, the police officer waiting outside the door became impatient and knocked on the door. Han Kuan quickly looked away, pulled up his pants with all his strength, and hurried out of the toilet...
"Team leader..." After the video was played, Wu Xiumin, who had always been steady, couldn't help but speak first. She looked at Zhao Yu with incredible eyes and said, "Team leader, who are you!? One in a billion. How likely is it that he could be hit by you? This... this is incredible!"
"It seems..." Miao Ying said with a solemn expression, "Is Han Kuan really related to the demon case that moved to the north?"
"I... I still can't figure it out..." Zeng Ke said in a confused manner, "How is this possible? It was Han Kuan himself who called us here. If he is one of the culprits in the demon case, wouldn't it be unreasonable? He Are you not worried at all that we will find out about him?"
"I don't know if he is the culprit!" Wu Xiumin put another laptop in front of everyone and said, "But Han Kuan's reaction definitely illustrates the problem!"
It turned out that what Wu Xiumin wanted everyone to see was the real-time monitoring in the cell. But when Han Kuan returned to the cage, he had obvious psychological fluctuations. He is no longer as calm and steady as before, but his eyes are evasive and extremely nervous, as if he is worried about something important...
"In the toilet, it was a kind of stress reaction!" Wu Xiumin said, "Han Kuan should have been unprepared for that sudden situation, so his reactions were objective and true! When he heard 'Devil Case' 'After three words, there was obvious abnormal behavior, which is enough to show that the team leader's words touched his secrets.
"So..." Wu Xiumin pointed to the two videos and said, "Judging from my professional perspective, Han Kuan must know some inside information about the demon case!"
"One of the five major unsolved cases! Haha..." Miao Ying shook her head and smiled, "I finally caught up with one! And... it's still so close! Who would have thought that the murderous demon of the Demon Case has always been by our side? Zhao Yu..." As he spoke, Miao Ying excitedly pulled Zhao Yu's arm and asked, "Tonight, Han Kuan will be sent back to the detention center! Should we interrogate him again now? Continue our frontal attack. Woolen cloth?"
"No..." At this moment, Zhao Yu had not recovered from the shock just now. Han Kuan's weird reaction in the video made him feel trembling and shuddering. He paused for a long time, and then said to Miao Ying, "A showdown now will have no effect! Without evidence, everything we are doing is just speculation, and there is no way to have a showdown!"
"And... don't you think..." Zhao Yu asked, "If we really had a showdown with him, wouldn't he be as worried as he is now?"
"Yes!" Zeng Ke said, "Where can we find evidence for such a long-standing case? If the Demon Case was easy to solve, I'm afraid it would have been solved long ago!"
"I... um..." Wu Xiumin said thoughtfully, "I can invite my teacher to arrange a hypnosis for Han Kuan! But... tsk tsk..." Wu Xiumin said helplessly to everyone, "In the first place, hypnosis is not necessarily possible. It really works;
“Secondly, even if it works, it cannot be used as evidence in court;
"Thirdly, hypnosis is the same as lie detection. Because it involves personal privacy, you need to obtain relevant legal permission! And if you want to get approval, you must have certain evidence! But... we have nothing. ah!
"So, based on Han Kuan's current situation, it is impossible for the higher-ups to approve it!"
"That's like talking for a long time in vain!" Zeng Ke said depressedly, "I think Han Kuan must be absolutely sure that we can't find anything, so he dared to call our special team! You are right, we are all being used by this person!"
"Almost!" Zhao Yu said bitterly, "I really underestimated this guy who writes novels! But..." At this point, Zhao Yu's eyes suddenly lit up, "But there is no need to be discouraged. , on the contrary, we should be happy! Don’t forget, we can win the first unsolved case of the headless female corpse, so what else can stop us?”
"So..." Miao Ying asked excitedly, "What other crazy idea have you come up with?"
"No!" Zhao Yu replied calmly, "The Han Kuan case is completely different from previous cases. This man is very thoughtful and is not someone who gives in easily! If we want him to tell the truth, we must get solid evidence. !
"Of course, you don't need to be too anxious!" He said to everyone in a comforting manner, "As the saying goes, nothing is difficult except for those who are determined. In the past, we felt that the case was difficult to solve because we had no goals and felt confused. But now, Now that we have a clear goal, we are one step further than before!"
"You're right..." Zeng Ke said flatteringly, "That's how it is on Yongjin Island. At first, we couldn't see the truth clearly, so we were very confused! But later, when we suddenly locked Dou Zili, we found clues and All the evidence was found in one fell swoop!”
"Yes!" Zhao Yu nodded, "That's what it means. Since we have now identified Han Kuan as a major suspect, as long as we focus our investigation around him and the demon case, we will definitely gain something!"
"Well... before we..." Wu Xiumin pointed to the documents on her desk and said, "we have investigated a lot of information about Han Kuan, but we didn't seem to find any problems..."
"These are not enough!" Zhao Yu said categorically, "Far from enough! The demon case is so far away, we must look further ahead!"
"Yes... that's right..." Zeng Ke understood and said immediately, "I'm going to investigate now. What was Han Kuan doing in the year when the demon case happened?"
"He was still in school at Yaoming at that time!" Wu Xiumin said, "It should be the year he was about to graduate! So... we need to focus on investigating Han Kuan's situation when he was in school and see who he dated. What happened?"
"Okay! Then I'm going to get the information on the Demon Case," Miao Ying said, "Let's go through the Demon Case again!"
"I think..." Wu Xiumin added, "Judging from Han Kuan's abnormal behavior in the toilet, I think there may be errors in the psychological assessment I made for him before! Han Kuan's psychological symptoms may be intermittent. tendency, so I need to re-draft an assessment test book and give him a detailed psychological assessment!
"If I can find the pattern of his psychological changes, maybe I can prescribe the right medicine and find his weaknesses!"
"Okay!" Zhao Yu was very pleased to see everyone's morale increased and their confidence increased. He immediately pointed to the two boxes and said, "In this case, let me go through these two boxes again and take a look. Is there anything else left behind? I think the demon case needs to be investigated intensively, but we can’t just leave the matter of Han Kuan killing his wife... "
