Detective: Start with capturing and retrieving the dog

Chapter 70 Evidence
The ability of criminal psychology is not only used to profile suspects, its essence is a study of human behavior, but the behavior of some criminals with mental illness is more abnormal than ordinary people.

But even special humans can study this ability thoroughly, let alone ordinary people.

As for the so-called shallow hypnosis, it is actually another application of "hypnosis aid". "Detective APP" taught him the ability, but he changed it a little.

The principle is also very simple. The reason why Guo Haisheng keeps using those fixed answers to the police's questions is because he is on alert. His brain will think about this question first, and then search from the answers Xu Ze gave him.

So Han Xin only needs to disturb Guo Haisheng's mind. First let Guo Haisheng immerse himself in memory through a resonant sentence, enter a state of light hypnosis, and then let his brain fall into chaos, so he will naturally not be so rational.

"Why is my fiancé so good?" Zhao Linshan smiled while tugging at his arm, "Do you know how to hypnotize?"

"Yes, I can hypnotize you and let you do whatever you want." Han Xin blinked maliciously.

Zhao Linshan looked at him puzzled: "You don't need to hypnotize me."

Han Xin was stunned for a moment, his heart was really moved at this moment. After recovering, he touched the top of Zhao Linshan's head and said with a smile, "Yes, after all, she is my childhood sweetheart and fiancee."

"?" Zhao Linshan looked at him with a smile, as if she didn't understand why his tone suddenly softened.

Soon, Guo Haisheng explained all the ins and outs of the matter.

However, when Huo Gang turned his head to interrogate Xu Ze, he had already regained his composure.

"That fat man did it himself, and framed me?" Xu Ze snorted coldly, "You have to figure it out, he is the pervert who installed surveillance equipment in other people's homes. What does he have to do with me? I have a girlfriend, why would I rape that dirty woman? Please tell me the evidence."

"Good boy, I have figured out a solution so quickly." Han Xin frowned and muttered.

Xu Ze's calmness surprised Han Xin. Obviously, this person was fully prepared. He knew the rules of conviction. At least two of them must be witnesses, physical evidence, and confession to confirm the objective facts of the crime.

Now the police only have witnesses, and there is still a lack of necessary physical evidence.So as long as Xu Ze resists the pressure of the police and refuses to let go, and cannot verify what Guo Haisheng explained, the police will not be able to convict him.

But now that there are witnesses, at least the police can detain Xu Ze and extend the interrogation time.

But to be on the safe side, physical evidence is still required.

However, when Lu Wenbo came back with a report from the technical department, the result was disappointing again.

Neither Xu Ze nor Guo Haisheng's fingerprints or DNA were found in the homes of the second person, and even their own fingerprints were very few, which showed that they had been cleaned on a large scale, or that they had prepared coverings in advance when committing crimes.

"Can you interrogate Guo Haisheng in the same way you just interrogated him?" Huo Gang asked tentatively.

Han Xin shook his head: "That method won't work if the prisoner is on guard against me."

The people at the scene fell into silence after hearing the words.

It was already [-]:[-] in the evening, and he thought that he might spend the night here tonight, so he let out a long sigh: "Oh, I thought I could get home quickly, but something went wrong all the time... It looks like it will be delayed until tomorrow."

"Ashin, what if there is really no evidence?" Zhao Linshan asked in a low voice.

"There is no evidence. There is no perfect crime in this world. It's just whether we can find it." Han Xin shook his head. "Now that technology is very advanced, it is rare to find clues due to technical reasons. It is because we did not find the right place."

Zhao Linshan patted him on the shoulder: "Oh, forget it, rest for a night, and think about it tomorrow when you are clearer."

"You go back to rest first." Huo Gang turned to Han Xin, "We have to interrogate him in turn, let him fall into a state of exhaustion, and see if there is any way for him to explain. I am afraid that in the end, Guo Haisheng will take the blame for him..."

Han Xin, who was about to turn around and leave the Public Security Bureau, was shocked when he heard the words, and stopped immediately.

So Zhao Linshan, who was following behind him, bumped her head against his back and cried out in pain, "Ouch! Why did you stop all of a sudden!?"

"Yes..." Han Xin grinned, "I thought of it... I know why Xu Ze was scared at that time!"

"Have you thought about it?" Huo Gang, who was about to enter the interrogation room, turned his head like lightning and grabbed his shoulder and asked.

"Think about it, before Guo Haisheng said that Xu Ze threatened him and let him take the blame alone." Han Xin tried his logic, "I suspect that this fat man has something to hide, and Xu Ze can let him take the blame alone... What does this mean? Xu Ze can not only exonerate himself, but also get Guo Haisheng convicted."

"You mean..." Wei Bin frowned, "Did he keep evidence of Guo Haisheng's crime? But what could it be?"

"Think about it carefully, my previous profile, why did I say that the murderer must have a girlfriend?" Han Xin asked with a smile.

"Because the victim did not have DNA, it means that he has taken protective measures." Hu Chen added, "The murderer decided to commit the murder based on the unexpected incident that Tao Wei wanted to return the watch, and according to the monitoring at the time, only Tao Wei had been in and out at the time of the crime. This means that the murderer had contraceptives at home, so there should be a target."

"Yes, but the person who actually committed the assault was Guo Haisheng. Is it possible that Xu Ze kept this used contraceptive to control and threaten Guo Haisheng? And when he was about to be found out, he could throw it at Guo Haisheng's house and frame him." Han Xin analyzed one by one, "This is the only and best evidence he can keep."

"Hey, it's so disgusting..." Zhao Linshan said disgustedly from the side.

"Although I'm not sure about this, I can only try it." Lu Wenbo said distressedly.

"I think the chances are very high." Han Xin looked confident. "I told Xu Ze that he became obviously nervous when I found out that there was a second murderer, probably because of this thing. We are progressing too fast, so he has no way to produce that evidence to frame Guo Haisheng. But as long as he does not plead guilty, he can use that thing to clear himself of suspicion after he is released on bail."

"We've searched his house thoroughly, but we didn't find anything like that." Wei Bin shook his head.

Han Xin pondered and said, "He probably wouldn't keep that thing at home... Check his recent whereabouts, whether he has rented a locker or a private warehouse, whether he has gone back to his hometown or to his girlfriend's house."

"Did you hear that?" Huo Gang ordered to his subordinates, "Go and verify now! Check carefully!"
