Forensic analysis of Gao An came to the conclusion that Principal Xu committed suicide.

Hearing this conclusion, He Jiahui couldn't wait to step forward and slap Gao An twice to make him sober.

He Jiahui glared at Gao An viciously, and said secretly in his heart: "If you don't know how to analyze, shut up, and the blind beep will make trouble for me!" ”

At this time, Zhang Dongsheng also added: "In fact, since the death of my mother-in-law, my father-in-law's mental state has not been very good, and he is always in a trance from time to time, and he always thinks about his mother-in-law. ”

"Mr. Zhang, didn't you just say that your father-in-law didn't behave abnormally?" Miao Zhishun immediately asked.

"Sir, you're asking if you've been behaving in any unusual ways lately. It's been more than two years since my mother-in-law died, and my father-in-law has been missing my mother-in-law very much, and we're all used to it, so this can't be regarded as a recent anomaly! Zhang Dongsheng argued.

He Jiahui said: "I don't think Principal Xu committed suicide, I met Principal Xu on the way here before, and I talked to Principal Xu.

He was a very talkative person, took the initiative to chat with me for a long time, and asked me a lot about the police academy. About this, we, the cadet policemen, and the accompanying instructors can prove it! ”

"That's true, we met the deceased at the third assembly point, and he was really talkative and kept talking to our cadet police." Li Wensheng nodded.

Qiu Junxuan, who was next to him, also spoke: "I can also prove that the deceased was a very talkative person, he had been chatting with me at the time, I didn't actually want to chat with him, but he was able to find something to say." ”

He Jiahui continued to analyze: "If a person wants to commit suicide, he should have a world-weary mood, and he will not take the initiative to talk to a stranger, let alone be curious about new things.

Just imagine, a person who wants to end himself and is dying must be discouraged, how can he care about the affairs of the police academy. ”

"What if my father-in-law remembers his mother-in-law and suddenly can't think about it and decides to commit suicide by jumping off a cliff? I watch TV and say that there are a lot of people who seem to be okay on the surface, but actually have depression! Zhang Dongsheng next to him said.

"Indeed, we cannot rule out the possibility of what you are talking about. But we can't rule out the possibility of him killing. He Jiahui said.

"He killed? This is impossible, there is only one person's footprints on the cliff, and there is only one person at the scene, either an accidental misstep or suicide, it is impossible for him to kill! Forensic Gao An immediately vetoed it.

"Who said that a man's footprints could not have been killed by him? I can make a kill and leave only one footprint. He Jiahui said, looked at Zhang Dongsheng silently, and continued:

"The murderer can lead the deceased to the edge of the cliff, then push the deceased off the cliff while he is unprepared, then clean the footprints and other marks on the cliff, and then walk backwards from the edge of the cliff, so that only one person's footprints will be left.

When the police investigate, only one person's footprints are collected, they will think that the deceased fell off a cliff or committed suicide, so the murderer can easily clear the relationship. ”

"No, there's a loophole in the method you're talking about." Gao An immediately retorted:

"We will compare the footprints with the forensic evidence, and if we compare the footprints on the cliff that are not the dead, then wouldn't it be a mistake?"

Therefore, the murderer should prepare a pair of shoes that are exactly the same as the deceased's feet, with the same brand, style, shoe size, and even the same degree of wear, so that the footprints left behind can match.

However, the degree of wear and tear is more difficult to imitate, and the best way is to let the deceased wear a new pair of shoes, so the murderer only needs to prepare a new pair of shoes of the same style to forge the same footprints. ”

He Jiahui looked at Gao An as he spoke, and asked, "Gao Sir, you should have paid attention to the deceased's shoes when you were collecting evidence, right?" Is it new? ”

"It's relatively new." Gao An nodded thoughtfully, and then said:

"But I still have a question, if your hypothesis is true, how did the murderer know when the deceased would be wearing new shoes? And also to have a clear understanding of the brand, style and size of the shoe? ”

"It's very simple, the murderer can send a new pair of shoes directly to the deceased!" He Jiahui smiled slightly, and then said:

"If the murderer is someone close to the deceased, then he can naturally know what size of shoes the deceased is wearing, and he can also give a new pair of shoes to the deceased.

Moreover, if someone close to him commits a crime, the deceased will not be defensive against the murderer, and the murderer can take advantage of his unpreparedness to push the deceased off the cliff! ”

Speaking of which, everyone's eyes were on the deceased's son-in-law, Zhang Dongsheng, and he was the only one at the scene who met this condition.

Zhang Dongsheng suddenly became nervous, and he said angrily: "What do you think I do? Do you think I killed my father-in-law? It's ridiculous! He's my father-in-law! ”

"Mr. Zhang, don't be nervous, I just said that this is just a possibility." He Jiahui continued: "Besides, to prove this possibility, evidence is needed, and I have no evidence in my hand. ”

Zhang Dongsheng snorted coldly: "So you were guessing just now?" Do you police rely on guesswork to handle cases? You are wronging good citizens! ”

"Mr. Zhang, I'm just a student policeman, not a formal policeman, theoretically I'm just like you, I'm an ordinary citizen, and it's not illegal for ordinary citizens to express their opinions, right?"

He Jiahui continued with a smile: "And I just said that I have no evidence in my hands, but I didn't say that others have no evidence in their hands!" ”

"He Jiahui, what the hell are you going to say, don't sell it!" Li Wensheng said from the side.

"Sir Li, if my inference just now is correct, the murderer forged the footprints on the cliff, it means that the murderer will have a pair of shoes that are exactly the same as the deceased. If we find that pair of shoes, we have the most direct evidence! ”

"That's true, but even if we have these shoes, where are we going to find them?" Li Wensheng asked.

He Jiahui looked at Zhang Dongsheng again: "Mr. Zhang, do you mind opening the hiking bag behind you and showing us it?" Maybe there's a pair of shoes in there. ”

"What do you mean? Why do you look at my hiking bag! You don't have the right to look at my hiking bag, it's my privacy! A hint of panic flashed in Zhang Dongsheng's eyes.

"I don't have that power, but the police do. I must warn you that someone has died here, and this is a homicide, and the police have reasonable grounds to apply for a search warrant to search everyone who comes here, including you. He Jiahui continued.

"Then why do you search only mine and not yours? If you want to search, everyone should search together! Zhang Dongsheng argued.

"I don't care! I'm not a murderer. He Jiahui spread his hands, and then said: "The backpacks of our cadet police officers are all over there, you can look at them casually!" But you, Mr. Zhang, would you like to open your backpack and show us your backpack? ”

"It's all mountaineering! Nothing to see. Zhang Dongsheng said, clenching the shoulder strap of the mountaineering bag.

Zhang Dongsheng's performance is tantamount to telling everyone that there is a cat in his mountaineering bag.

Miao Zhishun immediately stepped forward and spoke; "Mr. Zhang Dongsheng, please cooperate with our police investigation! Let's check your hiking bag. ”

After speaking, Miao Zhishun gave his officers a look, and his officers immediately went up and surrounded Zhang Dongsheng front and back.

Zhang Dongsheng's face had turned pale, and when things got to this point, he was powerless to resist, so he had to hand over his mountaineering bag.

The police officer immediately opened Zhang Dongsheng's hiking bag, and there was indeed a pair of sneakers inside!
