Forensic analysis conducted by Gao An concluded that Principal Xu committed suicide.

Hearing this conclusion, He Jiahui wanted to step forward and slap Gao An twice to make him sober up.

He Jiahui glared at Gao An fiercely and thought to himself: "If you don't know how to analyze, just shut up. Your blind beeping will only cause trouble for me!"

At this time, Zhang Dongsheng also added: "Actually, since the death of my mother-in-law, my father-in-law's mental state has not been very good. He is always in a trance from time to time, and he always talks about my mother-in-law. Could it be that my father-in-law misses my mother-in-law too much, so he

Suicide by jumping off a cliff?”

"Mr. Zhang, didn't you just say that your father-in-law had no abnormal behavior?" Miao Zhishun asked immediately.

"Sir, you are asking about any abnormal behavior recently. It has been more than two years since my mother-in-law passed away. My father-in-law has been missing her very much. We are all used to it. This cannot be considered an abnormal behavior recently!" Zhang Dongsheng defended.

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

He is a very talkative person and took the initiative to chat with me for a long time and asked me a lot about the police academy. Regarding this, we trainee police officers and the accompanying instructors can all attest to this!"

"Indeed, we met the deceased at the third assembly point. He was indeed very talkative and had been chatting with our school police officers." Li Wensheng nodded.

Qiu Junxuan, who was next to him, also said: "I can also prove that the deceased was a very talkative person. He was chatting with me all the time. I actually didn't want to chat with him, but he was able to find something to talk about."

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

Just imagine, a person who wants to commit suicide must be so desperate that he would care about the police academy."

"What if my father-in-law is recalling my mother-in-law, suddenly can't think about it anymore, and decides to commit suicide by jumping off a cliff? I saw on TV that there are many people who seem to be fine on the surface, but are actually suffering from depression!" Zhang Dongsheng said next to him.

"Indeed, we can't rule out the possibility you mentioned. But we can't rule out the possibility of homicide either," He Jiahui said.

"Homicide? This is impossible. There are only one person's footprints on the cliff, and there is only one person at the scene. Either he accidentally slipped or committed suicide. It is impossible to commit suicide!" Forensic Gao An immediately rejected it.

"Who says a person's footprints mean he can't be the murderer? I can cause a homicide and leave only one person's footprints." He Jiahui said, silently looking at Zhang Dongsheng, and then said:

"The murderer can lead the deceased to the edge of the cliff, then push the deceased off the cliff while he is not prepared, then clean up the footprints and other traces on the cliff, and then walk back from the cliff, so that only one person will be left.

's footprints.

During the investigation, if the police only collect one person's footprints, they will think that the deceased fell off a cliff or committed suicide, and the murderer can easily distance themselves from the relationship."

"No, there is a loophole in the method you mentioned." Gao An immediately retorted:

"Our forensics will compare the footprints. If we compare and find that the footprints on the cliff are not those of the deceased, then wouldn't it be a mistake?"

"So the murderer needs to prepare a pair of shoes that are exactly the same as those worn by the deceased. The brand, style, shoe size must be the same, and even the degree of wear and tear must be the same, so that the footprints left behind can match.

However, the degree of wear and tear is difficult to imitate. The best way is to let the deceased wear a new pair of shoes. Then 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 and asked, "Sir Gao, when you were collecting evidence, you should have paid attention to the deceased's shoes, right? Are they 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 wear new shoes? And he also had to know the brand, style and size of the shoes clearly?"

"It's very simple. The murderer can just give a new pair of shoes to the deceased!" He Jiahui smiled slightly and continued:

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

Moreover, when someone close to you commits a crime, the deceased will not be prepared for the murderer, and the murderer can take advantage of his unpreparedness and push the deceased off the cliff!"

Speaking of this, everyone turned their attention to Zhang Dongsheng, the son-in-law of the deceased, who was the only one on the scene who met this condition.

Zhang Dongsheng suddenly became nervous, and he said angrily: "What do you think I am doing? Do you think I killed my father-in-law? This is so ridiculous! He is my father-in-law!"

"Mr. Zhang, don't be nervous. I just said that this is just a possibility." He Jiahui continued: "Besides, evidence is needed to prove this possibility, and I don't have any evidence in my hand."

Zhang Dongsheng snorted coldly: "In other words, you were just making wild guesses? Do you police rely on wild guesses to handle cases? You are wronging good citizens!"

"Mr. Zhang, I am just a trainee police officer, not a formal police officer. In theory, I am an ordinary citizen like you. It is not illegal for ordinary citizens to express their opinions, right?"

He Jiahui continued with a smile: "And I just said that I don't have evidence in my hand, but I didn't say that others don't have evidence in their hands!"

"He Jiahui, what on earth are you going to say? Don't hold back!" Li Wensheng said from the side.

"Sir Li, if my inference just now is correct and 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 those shoes, we will have the most direct evidence!

"

"That's the truth, but even if we have these shoes, where should we find them?" Li Wensheng asked.

He Jiahui looked at Zhang Dongsheng again: "Mr. Zhang, would you mind opening the hiking bag behind you and showing us? Maybe there will be a pair of shoes inside."

"What do you mean? Why do you look at my hiking bag? You have no right to look at my hiking bag. This involves my personal privacy!" A trace of panic flashed in Zhang Dongsheng's eyes.

"I don't have this power, but the police do. I must remind you that someone died here. This is a murder case. The police have reasonable grounds to apply for a search warrant to search everyone who appears here, including you.

." He Jiahui continued.

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

"I don't care! I'm not a murderer." He Jiahui spread his hands and continued: "The backpacks of us trainee police officers are over there, you can look at them as you like! It's up to you, Mr. Zhang, if you want to open them for us to see.

Where is your backpack?"

"These are all mountaineering-related items! There's nothing good to see." Zhang Dongsheng said, holding the shoulder strap of the mountaineering bag tightly.

Zhang Dongsheng's behavior clearly told everyone that there was something fishy in his hiking bag.

Miao Zhishun immediately stepped forward and said, "Mr. Zhang Dongsheng, please cooperate with our police investigation! Let us check your hiking bag."

After saying that, Miao Zhishun winked at his police officers, who immediately went up and surrounded Zhang Dongsheng.

Zhang Dongsheng's face had turned pale. When the matter reached this point, he was unable to resist and had no choice but to hand over his mountaineering bag.
