Facing the confusion on everyone's faces, Su Yan further began to explain.
"As for the fact that the deceased clearly saw the murderer holding a kitchen knife, but he did not take any precautions, a comrade just said, maybe it is because the deceased did not discover the murderer's intention."
"My guess is that the deceased misunderstood the murderer's intention. The murderer used some behavior or words to make the deceased not think that the murderer would kill him."
When everyone heard this, they were quiet for a while.
After thinking for a moment, Lu Haiping frowned and said: "If this is the case, the murderer may not be someone particularly familiar to the deceased. Most people can also coax the deceased if they talk cleverly!"
Su Yan smiled: "What kind of person is so good at talking, holding a kitchen knife in his hand, and the deceased did not take any precautions, and even the deceased knew that this person had done bad things."
Upon hearing Su Yan's words, the re-elected forensic doctor also retorted: "For the time being, we assume that the deceased and the murderer were very familiar with each other, but Xiao Su, how do you know that the deceased knew that the murderer had done bad things?"
"Yes, the murderer may be afraid that the deceased will know what he did in the future and kill him in advance!"
Faced with everyone's different opinions, Su Yan smiled slightly and said: "We can completely analyze whether the deceased knew the murderer's crime."
"Ah?" Everyone at the scene was an old police officer, so they naturally had the ability to make inferences and analyses, but they couldn't come to Su Yan's conclusion.
"By what analysis?" Forensic Doctor Ren asked in astonishment.
Su Yan pointed to the mobile phone in the hand of forensic doctor Ren and said: "The clues are on this mobile phone."
"How do you say this?" Forensic Doctor Ren and others were stunned.
The phone has been burned long ago and is completely unrecoverable.
"Xiao Su, is your clue someone who the deceased talked to on the phone that night and what he said?" Lu Haiping asked.
When everyone heard this, they couldn't help but shake their heads. If so, Su Yan's inference was extremely mediocre, because the deceased did not talk to anyone that night, except for calling Tiezhuo.
Regarding this point, Lu Haiping had already told Su Yan on the way here. He was afraid that Su Yan would be negligent, so he told the original words again at this time.
"The deceased didn't get through to Tiezhuo last night, and he didn't talk to anyone else. We checked the communication company, and this is absolutely correct."
Lu Haiping promised.
Su Yan didn't say anything, but took the mobile phone from forensic doctor Ren, and then found a clean rag to wipe off the black smoke sludge on the surface of the mobile phone case, revealing the metallic luster.
"Sure enough!" Su Yan nodded as he looked at the exposed metal shell.
"Xiao Su, is there something wrong with this metal shell?" Forensic Doctor Ren asked curiously.
Su Yan pointed to the depressed part of the metal surface and said, "Look at this depression, the paint has fallen off, but the surrounding paint is intact."
Everyone observed and nodded: "That's true, but what does this mean?"
"This shows that the phone was hit with a heavy object and the paint was knocked off." Su Yan raised his eyebrows and said in a deep voice.
"..."
Everyone looked at the peeling paint, and then Li Kejun frowned: "You think this is a clue? The peeling paint may have been accidentally caused by the deceased at some time during his lifetime."
Su Yan's expression became solemn, "I'll do another experiment for you to see!"
As he spoke, he placed the phone next to the ear of the deceased's body and carefully adjusted it up and down several times.
Everyone was confused for a moment and didn't understand what Su Yan was going to do.
After adjusting the position of the phone next to the ear of the corpse, Su Yan pointed to the wound on the back of the deceased's head and said, "Look, what is the connection between the dent in the phone and the wound?"
Everyone looked over immediately.
"Yeah!" This time, it was the criminal technicians who were the first to shout in surprise.
They have been doing survey work for a long time, and their eyes are naturally more vicious and sharp than ordinary people. After Su Yan's reminder, they immediately understood.
At this time, other comrades were still unclear, so they all asked: "What is the connection between the wound and the mobile phone?"
A criminal technician paused and then explained word for word: "The depression of the mobile phone is in line with the wound of the deceased."
“And that line is the curve of the woodcutter’s blade.”
"Ah?" When everyone heard this, they were all shocked and looked carefully again.
After careful observation and comparison, no one had any doubts. After the damaged part of the mobile phone was connected to the wound on the back of the deceased's head, a curve similar to the blade of a machete was indeed formed.
"Hiss", after everyone saw it clearly, they all took a breath.
"The deceased was hacked to death by the murderer while he was on the phone. But, Officer Su, how did you think of this?" Everyone swallowed and said with difficulty.
Su Yan's magical reasoning ability undoubtedly shocked them.
What kind of insight does it take to discover this?
At this time, even Li Kejun couldn't help but admire Su Yan.
"But Xiao Su, although your discovery is very important, you just said that the deceased knew the murderer. Now even if you know that the deceased was killed on the phone, you can't prove this!"
Lu Haiping woke up from the shock and asked Su Yandao.
Su Yan nodded and said: "We know that the deceased only called Tie Zhuo last night, which means that the deceased called Tie Zhuo when he was killed."
When everyone heard this, they all nodded thoughtfully.
Li Kejun frowned: "In this case, Tie Zhuo cannot be the murderer."
Li Kejun had always suspected that Tie Zhuo was the murderer, but now he found out through Su Yan that he knew that Tie Zhuo could not be the murderer, otherwise the deceased would not have called him before he died.
"Well," Su Yan said, "Tie Zhuo is indeed not the murderer. There are several inconsistencies in his characteristics."
Li Kejun nodded. This time he agreed with Su Yan and for the first time no longer doubted that Tiezhuo was the murderer.
Lu Haiping was very happy when he saw that Tie Zhuo was cleared of suspicion. After all, Tie Zhuo was a colleague and no one wanted him to be the murderer.
Su Yan continued: "We know that the deceased hated Tiezhuo because of his daughter's suicide. He even cursed him during the day. I was also present at the time. The hatred of the deceased is real."
"But at night, he actually called Tiezhuo, which shows that his thinking has changed."
"Why is there such a huge change? I still hate people so much during the day, but I take the initiative to contact them at night." Su Yan asked, looking at everyone.
"Why?" the policeman from the police station who just mocked Su Yan blurted out.
Su Yan glanced at the policeman and smiled.
The policeman's face suddenly turned red. Just now he looked down on Su Yan and turned around to ask for advice. It was really funny.
However, the reason why he satirized Su Yan was not because he disliked Su Yan, but because he saw that director Li Kejun had some thoughts about Su Yan.
He just wanted to flatter Li Kejun.
Now that I saw that Su Yan was not trying to show off, but that he was really capable, I couldn't help but look at Su Yan with admiration, and my attitude became respectful.
When asked by the policeman, Su Yan did not deliberately create difficulties and said directly: "The deceased must have discovered something and wanted to tell Tiezhuo, but he was secretly hacked to death by the murderer."
"Ah!" Although everyone was a policeman, they couldn't help but exclaimed when they heard Su Yan say this.
They could imagine the tragedy and weirdness of the scene.
Li Kejun said at this time: "The deceased knew something. He wanted to tell Tie Zhuo, but the murderer couldn't wait to kill him. This shows that the deceased knew something about the murderer."
Li Kejun used to be the deputy captain of the criminal police team before becoming the director of the police station. He had good inference and comprehension skills. He followed Su Yan's meaning and came to the corresponding conclusion.
Su Yan nodded and continued: "That's true. The deceased knew what the murderer had done at the time and even called to expose him."
"But he still didn't guard against the murderer holding the woodcutter. The reason may be that the murderer's intention of holding the woodcutter misunderstood the deceased!"
"What kind of misunderstanding caused the deceased to take no precautions?" Lu Haiping asked puzzledly.
"Suicide!" Su Yan raised his eyebrows. "The deceased was holding a woodcutter at the time. Perhaps he wanted to threaten the deceased, saying that he would commit suicide, and then force the deceased not to reveal his crime."
"But obviously, the deceased was not threatened and still called Tiezhuo, which led to the murderer's surprise attack and killed the deceased!"
"Since the murderer was able to threaten the deceased with suicide, it shows that they had an unusual relationship in the past, so both parties must be very familiar with each other!"
"Hiss", when everyone heard this, they took a breath again. Although what Su Yan said was just speculation, they believed it to be the truth.
After the analysis, Su Yan returned the phone to forensic doctor Ren, patted the dirt on his hands and said: "This is what happened and the situation should be like this!"
Silence, after Su Yan finished speaking, the scene was completely silent.
It can be said that Su Yan's inferences and analyzes all shocked everyone.
They never thought that a person, especially a young man who had only been working for a few days, would be so capable, and his inferences were so insightful and unique that it was simply amazing!
Li Kejun and his comrades from the police station murmured not knowing what to say. They wanted to apologize to Su Yan for their previous attitude, but they had no words for the moment.
