The interrogation of Wen Tao lasted for two hours, during which some police officers who watched the excitement left one after another, leaving only those who still needed to stay at their posts and Gao Qilu, who was full of various thoughts.

The time was near, but everyone was still sleepy.

Wang Gang and Wei Xiao finally came out of the interrogation room, and some of the policemen who had not yet left greeted them.

"How's it going, head, did the kid do you?" These were the first two police officers to take over the interrogation position.

"Team Wang, Team Wei, is he a murderer?" This one has recently worked overtime for a few days in a row, and he is not in a good mood.

"Boss, is the process going well?" This is an old policeman who is about the same age as Wang Gang.

There was no response, Wang Gang's sharp eyes directly crossed the crowd and stared at Gao Qilu.

"Doctor Gao, we may need you to cooperate with our investigation." Squinting slightly, Wang Gang said with a smile.

Wang Gang did not directly point out the identity of Gao Qilu's suspect, but used the words "cooperate with the investigation", and the surrounding police just thought that it was as usual, to help analyze Wen Tao's micro-expressions and psychological changes, and find the other party's psychological weaknesses and language loopholes, so as to defeat Wen Tao's seemingly solid shell, revealing his uneasy and nervous heart.

It seems that it is because Gao Qilu's identity has not been determined to give him face, and it is also to make Gao Qilu relax his vigilance, feeling that Wang Gang has not completely suspected him. But the change in Wang Gang's eyes means that he has a trace of suspicion about Gao Qilu in his heart, which is also in line with his identity as a veteran criminal policeman for more than 30 years - full of doubts about everything!

In the confrontation with a high-IQ criminal like Gao Qilu, there can be no sloppiness from language to eyes and posture.

Gao Qilu smiled slightly, and confidently followed Wang Gang and Wei Xiao into the interrogation room next to Wen Tao, because the two interrogation rooms need to pass through the same outside door first, so the police outside don't know which door Gao Qilu entered, and the police in the monitoring room don't know what happened between them, so naturally they won't say much.

After all, if they can be assigned to the department that knows the most secrets, their mouths are naturally the strongest.

In order to relax Gao Qilu's vigilance, he didn't put handcuffs on him, and chatted directly after sitting down.

"Doctor Gao, you should know why we brought you in, right? Hey, just go through the motions, we also believe that you are a good person, there must be some misunderstanding in it. Wang Gang was full of smiles, as if he really believed in the person in front of him.

Gao Qilu shook his head, his face was angry: "I know he thinks I'm a murderer, but isn't this a joke?" I was knocked unconscious while walking on the street, and I was called a murderer for no reason, this kind of person is either in his right mind or is in a hurry to find a scapegoat, right? ”

Wang Gang nodded and agreed: "I said the same thing just now, he kept saying that he had evidence, but he couldn't come up with evidence, and finally said that there were other eyewitnesses who were at the scene at the time. But he has always refused to let go of the identity of the witnesses, saying what is to protect the witnesses, isn't this nonsense, if there are really witnesses, can we not protect them well? ”

"By comparing it with the blood remaining on the knife, although the murder weapon was found in the trash can near the scene, it was the same as the previous three times, no fingerprints were left on it, the trademark was torn off, and nothing was photographed by the on-site surveillance, even if he didn't lie, just one witness and his testimony were not enough to convict, and it is very likely that he said this just to delay time."

"But this is also a good thing, since he is sure that you are the murderer, and you also think that he is the murderer, then in the case of excluding the wrong person, the murderer should now be between you and him. Oh, and that mysterious 'witness'. ”

"Since he refuses to recruit him, we have to gather other evidence first, and the first priority is to find the witness he is talking about, or if it can be proved that this so-called witness does not exist, this will be one of the key corroborative evidence for our conviction. A person who is full of lies has very little credibility in court. ”

Gao Qilu listened to Wang Gang's words, his smile was even brighter, and he nodded in agreement.

Wang Gang seemed to believe in Gao Qilu very much, and almost decided that Wen Tao was the murderer when he was happy to choose one of the two, but Wei Xiao next to him stopped talking.

Gao Qilu saw it: "Does Team Wei have anything to say?" ”

Seeing that Wang Gang didn't react, Wei Xiao shook his head and said: "Although I am not particularly familiar with Wen Tao, but with my understanding of him, I should not be able to do such a thing as murder, I think there must be some misunderstanding, maybe the key to all this is in this 'witness'." ”

Gao Qilu smiled and said, "Team Wei, you don't know your heart. "It seems that there is something in the words.

Wang Gang's eyes when he first looked at him were naturally captured by him, and he also knew that Wang Gang, who seemed to be connected to his heart, did not completely trust him, but was still wary of him to a certain extent. On the contrary, it was Wei Xiao, who knew Wen Tao, who believed in himself more.

Wang Gang patted his head, and Gao Qilu said: "By the way, Doctor Gao, what did you say on the phone to Wang Ju before, and how did you know that he was the murderer?" ”

Gao Qilu had long known that they would ask this question, and explained unhurriedly: "I was still dizzy before I was taken into the car because I fainted before, and I didn't know what was going on. If it hadn't been for a young police officer next to me telling me, I wouldn't have known that I almost became the murderer of the serial murders in the past two days, but don't blame people for violating discipline, after all, this is also a good heart. ”

"At first, I thought it was a misunderstanding, but with my years of experience in criminal psychology, something was not quite right."

"On the premise that he couldn't produce evidence, he was so eager and determined to put the charge on me, and even knocked me unconscious, this must be more than a simple misunderstanding. Even if he wasn't the murderer, he definitely had something to do with the murderer, so I called Wang Ju to keep the other party first and see how he would react in the face of interrogation. ”

But instead of doubting the possibility of his misjudgment, he now had another witness come out. From my point of view, the more firmly he believes that I am a murderer, the more suspicious he will be, given that I am innocent. I just don't know why, he must put this 'suspect' on my body, this is the only thing I wonder. ”
