Li Xiuyuan did not deny that he had kicked Liu Rui, and even told him all the places he could think of and the places he had encountered when he was entangled with Liu Rui.

This kind of attitude that is convenient for Shen Siyan to verify makes Shen Siyan doubt him a lot.

"I believe your word for the time being, and I hope you don't let me down again."

After questioning, Shen Siyan left the interrogation room and sat on the chair a little dazedly.

Gu Yanyan walked over, holding a Coke that I don't know who went out to bring back.

"Oh, fat house happy water, make you happy, otherwise I'm really afraid that our Shen University forensic doctor will make the first mistake in his career."

Gu Yanyan's words were a little ridiculous, deliberately adjusting the atmosphere.

Shen Siyan tugged at the corners of his mouth a little weakly.

"I feel bad."

Shen Siyan pinched the coke, "If I stop a little, won't anyone die?" ”

Gu Yanyan almost spit out the Coke she drank in her mouth.

"I want to wake you up."

She put the Coke aside.

"First of all, the premise of what you say is that you think Li Xiuyuan is a murderer, and you think he is a murderer before you think you are guilty."

"Isn't he?" Shen Siyan's face was a little more mocking.

"I really can't believe him after seeing him almost kill someone, let alone ......"

Shen Siyan stood up.

"I didn't say something just now, in fact, Liu Rui's fatal wound is in the chest, and it can't be separated from Li Xiuyuan's kick."

Shen Siyan's face was a little dazed, "Although I determined that the cause of death was because the dagger was inserted into the lungs, but if it weren't for Li Xiuyuan who injured Liu Rui, Liu Rui would still have a chance to be rescued." ”

"But in fact, Li Xiuyuan didn't cause fatal injuries, did he?"

It was rare for Gu Yanyan to see Shen Siyan so sharp and lose her previous wisdom.

Shen Siyan pursed her lips, knowing that what Gu Yanyan said was right.

"But on Liu Rui's body, I didn't find any other traces, only the traces left by Li Xiuyuan."

But as long as Shen Siyan can easily find one, the hair from other people, Shen Siyan's heart will feel better.

Gu Yanyan scratched her head, a little unsure how to comfort Shen Siyan, she was not good at these things.

"But Li Xiuyuan has quarreled with Liu Rui and has had a lot of contact, whether intentionally or unintentionally, he will definitely leave a lot of things."

It was Zhang Nanmu who came from behind.

"Siyan, you don't meditate."

He took advantage of the situation to sit next to Gu Yanxi, and continued to speak despite Gu Yanyan's gratitude to him.

"You know very well that your profession requires you to calm down and look for clues, but so many traces belonging to Li Xiuyuan make you panic, that's why you are so troubled."

Zhang Nanmu looked at Li Xiuyuan, who was pulling his head in the interrogation room, and sighed.

"Actually, in the final analysis, it's because of your guilt."

Zhang Nanmu calmly helped Shen Siyan analyze.

"But Siyan, you forgot, even if you stop Li Xiuyuan, if Li Xiuyuan wants to kill Liu Rui, there will still be many opportunities."

If the murderous intent really rises, then it is far from enough to stop it once.

Shen Siyan's eyes finally became clearer.

She lowered her eyes and looked at the Coke in her hand in a daze, thinking about Zhang Nanmu's words in her head.

Zhang Nanmu and Gu Yanxi didn't bother her.

After a while, Shen Siyan raised his head, his eyes shining.

"I see, thank you Team Zhang."

She can't keep drilling like this, whether the deceased is a bad person or not, whether she deserves death or not, as a forensic doctor, she should dutifully find the truth about the deceased's death.

Although Shen Siyan handled this very well, he didn't stop investigating the case because he hated Liu Rui.

But Shen Siyan was stopped by a sense of guilt, she preconceived suspicion of Li Xiuyuan, and felt that she was ashamed of Liu Rui.

The heart is not pure, and there is prejudice, there is no way to get to the bottom of the case.

Gu Yan hugged Shen Siyan's arm with a sigh.

"You've finally figured it out, woo, looking at you tonight, I'm almost in a hurry, you don't have to thank this guy, he just wants you to work hard."

was said to be like this by his eccentric girlfriend, Zhang Nanmu touched his nose, and he was not angry at all.

"You're right, you don't have to thank me, you are the key to investigating the case, don't be sloppy."

Zhang Nanmu stood up.

"Whether the murderer is Li Xiuyuan or not, I will catch him."

But in fact, Zhang Nanmu suspected Li Xiuyuan.

"It's hard tonight, check as much as you can, adjust your mentality, don't go wrong."

Shen Siyan nodded.

"Don't worry, Team Zhang, I'll be serious."

Zhang Nanmu nodded and touched Gu Yan's head.

"The comrades who investigated at the scene came back with the clues they found, don't bother Siyan, go back with me."

Gu Yanyan's face was full of reluctance, and she stuck out her tongue at Shen Siyan and was dragged away.

Shen Siyan returned to her workspace, this time she calmed down and checked Liu Rui's body inch by inch.

Halfway through, Lu Qian made a phone call, Shen Siyan probably said about the situation, turned off the phone and continued the work at hand.

Compared with Li Xiuyuan's confession, Shen Siyan found out the traces on the places that Li Xiuyuan's confession did not mention, and Zhou Manshan, who handed in the trace examination, deduced the situation at that time one by one.

The two of them found out about the night without distraction.

Zhou Manshan sighed, "If that person didn't lie, the place where these fingerprints might indeed be accidental, and there are basically no traces of the murderer's knife." ”

"Well, normal people don't think about where they have met the victim in advance, and make up for the confession in advance."

Shen Siyan drew on the book and continued: "And according to my investigation, every knife of the murderer was not fully inserted. ”

"That's weird."

Zhou Manshan held her chin.

"According to the description of eyewitnesses, every blow of the murderer at that time was very fast, and with that kind of impact, it would definitely be stabbed to the end."

Shen Siyan nodded, "I deduced the attribute of the murder weapon according to the condition of the wound, here." ”

Shen Siyan pondered the inspection report while handing the paper on his left hand to Zhou Manshan.

"This kind of dagger shouldn't be stuck in the end, repeat offender?"

The kind of habitual offender who has experience and knows that sticking a dagger too tightly will leave a trace, but it may leave a little gap.

Shen Siyan rubbed his neck, "It may also be that the arm has no strength, and the witnesses said at that time that they didn't say which hand the murderer used?" ”

Zhou Manshan shook her head, "I don't know much about this. ”

Shen Siyan raised his eyes, just about to speak.

"Buckle up."

The sound of the door remembered, and Shen Siyan closed his voice, "Please come in." ”

"Sister Shen, Sister Zhou."

The little policeman who came in greeted them, and then said with a smile: "We just checked the bloodstains at the scene, and there is a place where I feel that there is something missing, which may have touched the suspect, Sister Zhou should take a look." ”

Zhou Manshan got up and said with a faint smile: "Okay, I'll take a look." ”

She looked back at Shen Siyan, "Then I'll go first." ”

Shen Siyan nodded, lowered his head and continued to look at his information.

"Sister Shen."

The little policeman called him, "Sister Gu told you to come over." ”

"Call me?"

Shen Siyan frowned, and then stretched out, "I'll go now, you go back with Manshan first." ”

After Zhou Manshan left with the little policeman, Shen Siyan packed up the things on his desk and went to find Gu Yanyan.

"Siyan, hurry up and take a look at this."

As soon as she saw Shen Siyan, Gu Yanyan beckoned to her.

Shen Siyan took two quick steps and picked up the photo in Gu Yanyan's hand, "The murder weapon?" ”

"Well, pay attention to the scene, this is the coffee shop where Li Xiuyuan was before, and according to the boss's words, Li Xiuyuan sat down here."

Shen Siyan was stunned, "I just did an investigation and found that the murderer may not be Li Xiuyuan." ”

Shen Siyan did suspect Li Xiuyuan before, but it turned out that Li Xiuyuan had no other contact with Liu Rui except for meeting Liu Rui a few times when he was arguing with Liu Rui.

And she has known Li Xiuyuan for a long time, and knows that although Li Xiuyuan looks thin, he actually has strength in his hands.

From these two points, Li Xiuyuan's suspicion is much weaker.

Shen Siyan told Gu Yanyan about the situation.

Gu Yanyan pinched her chin when she heard this, and said thoughtfully: "According to what you say, it really doesn't look like Li Xiuyuan, but the murder weapon has Li Xiuyuan's fingerprints on it......"

"Fingerprints?" Shen Siyan felt that his head was a little insufficient, "What about the murder weapon?" ”

Gu Yanyan walked to the table next to her and pointed to the dagger wrapped in the bag.

It is the same as the specifications inferred by Shen Siyan.

However, what caught Shen Siyan's attention even more was the fingerprint on the dagger that had been processed and revealed.

"This fingerprint will be sent to Manshan for examination in a while, I'll show you first, if it's really Li Xiuyuan......"

"It's Li Xiuyuan's." Shen Siyan said categorically.

"I just compared Li Xiuyuan's fingerprints with Manshan, and I can recognize them, but just in case, let's check them."

That being said, in fact, Shen Siyan had already affirmed that the fingerprint belonged to Li Xiuyuan.

If that's the case, then everything she's just found out should be overturned.

Did Li Xiuyuan really kill someone?

Shen Siyan couldn't be sure that he was not suspicious.

Zhou Manshan's results came out quickly, and the fingerprints on the dagger were Li Xiuyuan's.

Gu Yanyan immediately dragged Shen Siyan to the interrogation room.

"Have you ever seen this?"

Li Xiuyuan shook his head, "I don't know." ”

"Hmph." Gu Yanyan snorted coldly, "You lie, if you haven't seen it, how can you have your fingerprints?" ”

"Officer Gu, it's really not me, I haven't seen the dagger you said, and I don't know why my fingerprints are here, someone is framing me!"

Li Xiuyuan said that he didn't admit that he knew this dagger, but Gu Yanyan felt that he was hard-mouthed.

"Okay, then explain what you did after arguing with Liu Rui?"

"I told you, I went straight into the café and didn't come out."

"You're lying!"

Gu Yan's face was straight, "The monitoring of the café is pregnant, but the traffic monitoring shows that you did not stay in the café all the time, but left halfway, rushed over and stabbed Liu Rui seven times who was taking a taxi at the intersection." ”

"Surveillance?"

The first person to be blindfolded was Shen Siyan.
