"Zhou Yan!" The police officer in front of the interrogation table patted the table, "Please cooperate with our work, confess leniently, and resist strictly!" ”

Zhou Yan was speechless, glanced at the police, and crossed her legs on the table, "Why didn't I cooperate?" I've already said what I need to say, but you don't believe it, what can I do! What the hell do you want me to say? Do you want me to say that I killed someone? ”

She didn't kill anyone, she's not afraid!

When encountering such a person, the police in charge of interrogation were also helpless, and continued: "Tell me, where were you from 19 o'clock to 22 o'clock last night?" ”

"I'm ......" Speaking of this, Zhou Yan showed a smile and looked at the policeman's little brother Sun Chao, "I'm sleeping with the guests, as for how I accompany you, do you want to hear something more specific?" ”

In the end, he is engaged in this business, Zhou Yan said this teasing words, but her face was not red and her heart was not beating.

After speaking, Zhou Yan also threw a wink at the little brother of the police.

"If you want to hear it, I can whisper it to you in private."

Sun Chao patted the table, "Zhou Yan! Please be serious! ”

Zhou Yan snorted coldly, "Am I not serious?" You have to ask, I answered truthfully, and you dislike me for not being serious, what do you want me to do? Either you give me a standard answer, and I'll answer according to your standard answer. ”

At this moment, Sister Ling stood on the side and knocked on the door.

Sun Chao stood up, "Sister Ling." ”

Sister Ling nodded, "What do you say?" ”

Sun Chao's face was very ugly, "She has been uncooperative!" ”

As soon as she heard this, Zhou Yan immediately shouted that she was wronged, "Comrade police officer, I have said everything that should be said, although my profession is a bit special, but you can't discriminate!" ”

Sister Ling walked up to Zhou Yan, "As far as I know, Liu Manshan is your husband who just got the certificate. ”

"Yes," Zhou Yan glanced at Sister Ling, "What's wrong?" ”

Sister Ling frowned slightly, "Your newlywed husband was murdered and died tragically, as a wife, why aren't you sad at all?" ”

"I don't have any feelings for him in the first place, why should I be sad?" Speaking of this, Zhou Yan continued: "If he dies, can't I look for him again?" ”

And at the beginning, Zhou Yan was originally interested in Liu Manshan's money.

If it weren't for Liu Manshan saying that he had real estate in the capital, Zhou Yan would not have obtained the certificate from Liu Manshan.

"How did you and Liu Manshan meet?"

"I met in bed." Zhou Yan replied.

Met in bed.

Hearing this, even Sister Ling frowned slightly.

"You'd better be honest with me," Song Wu bent down slightly, propped her hands on the interrogation table, and looked at Zhou Yan with a pair of peach blossom eyes, her whole body was full of a sense of oppression that made people unable to breathe, "This is the police station, not your home, if you don't cooperate well, once you get out of this interrogation room, the police will investigate you, dig deep into your life, and find out all the truth, at that time." Maybe your relatives and friends will also know about your current living situation. So, you'd better think a little more before answering. ”

Hearing this, Zhou Yan was stunned.

Looking at Song Wu, she swallowed her throat a little nervously.

"Y-you're scaring me?"

The pear vortex at the corner of Song Yan's mouth was shallow, she was clearly smiling, but she didn't feel any warmth, but it made Zhou Yan very nervous.

"The door is open, and if you want to go, you can do it right now."

Speaking of this, Sister Ling immediately cooperated with Song Wu and walked over to open the door.

Smack.

The door opened.

A beam of light shone in through the door.

Zhou Yan turned her head to look out the door, and when she thought of Song Yan's sentence 'dig deep into your life', where did she dare to leave?

Zhou Yan looked at Song Wu, "Little comrade, it was my wrong attitude before, I apologize to you!" ”

Although she doesn't feel ashamed of her profession,

But she still doesn't want to be known by relatives and friends.

Especially those from my hometown.

People have relatives and friends in their hometowns, and they all want to be embarrassed after all.

I have to say that Song Wu pinched her seven inches very well.

After saying a word, Zhou Yan silently withdrew her feet on the table, sat up straight, and straightened her attitude, for fear that she would offend Song Wu in the next second.

It's like a schoolboy who has done something wrong and sees the head teacher.

Some are scared, some are well-behaved.

Seeing this, Sister Ling looked at Song Wu with a look of surprise in her eyes.

This girl impressed her again.

The momentum on Song Wu's body is not even in these people.

The others in the interrogation room were also shocked.

If you hadn't seen it with your own eyes, who would have believed that a little girl who was only seventeen or eighteen years old would have such courage!

Song Wu looked at Zhou Yan, and then asked, "How long have you known Liu Manshan?" How did you two meet? ”

Her voice was faint.

But it made people tremble, especially Zhou Yan, she mixed in the night scene and met all kinds of people, but it was the first time she had seen her like Song Yan.

Obviously, she doesn't look very old, she is still very beautiful, and she doesn't have any offensive power, but inexplicably it makes people a little flustered, and they don't even dare to look at her directly.

It's as if nothing can escape her eyes.

The atmosphere became tense for a while.

Faced with Song Wan's question, Zhou Yan answered honestly, "I met Liu Manshan half a month ago, and he was my guest at that time. After that time, he came to me every day, and said that he wanted to take me to live a good life, and he told me that his biological daughter was very capable, and had a car and a house in the capital, in fact, I didn't believe what he said at first, until a week ago, he took me to his daughter's house. Then the next day, we went to get the permit......"

Song Wu nodded slightly, "Then where were you on the day of Liu Manshan's accident?" Who can testify for you? ”

"I received a guest that night......"

Song Wu frowned slightly, interrupting Zhou Yan's unfinished words, "Didn't you already get the certificate with Liu Manshan?" ”

"I got the certificate, but his function is not very good...... Speaking of this, Zhou Yan was a little ashamed, "I'm only thirty years old this year, and I can't follow him to stay alive and widowed...... It was already twelve o'clock after we were done, and when I came back to find that our house had been cordoned off by the police, I knew that Lao Liu had been killed! ”

"This little comrade, you believe me, this matter really has nothing to do with me! I got the certificate with Lao Liu, and I plan to divide his family's property! Who knew he would be killed! ”

After speaking, Zhou Yan continued: "Little comrade, do you have anything else you want to ask?" ”

She was afraid that if she didn't answer well, the police would launch an in-depth investigation into her.

If her relatives in her hometown found out what she was doing in the city, she wouldn't be able to see anyone!

"How is Liu Xiaofang's attitude towards you these days?" Song Wu then asked.

"Liu Xiaofang? Are you talking about Liu Manshan's daughter? Zhou Yan asked.

Song Wu bowed slightly.

Zhou Yan said: "If you say that the attitude is not good, she is okay, you say it is okay, I think she is yin and yang!" But I can see that Liu Xiaofang looks down on me very much, and on the first day we moved with Lao Liu, Liu Xiaofang had a big fight with us! She also wanted to kick me and her dad out, and later, Liu Xiaofang's big star brother also came, and her big star brother also took a kitchen knife at that time, saying that he was going to kill Lao Liu! ”

Speaking of this, Zhou Yan seemed to suddenly remember something, and continued: "I originally thought that Liu Xiaofang would definitely kick us out with her big star brother, but I didn't expect Liu Xiaofang to find out with her conscience, and begged her big star brother not to embarrass Lao Liu, and she also snatched the kitchen knife from the big star's hand." It was also from that day that Liu Xiaofang's attitude towards Lao Liu changed, at least, he didn't kick us out again! I thought I would be able to live a good life for a few days from now on, but who would have thought that Lao Liu would be killed! ”

Zhou Yan's words seem unimportant, but in fact, they provide a very important piece of information.

That's why Song Yiyan's attitude towards Liu Manshan suddenly made a 180° turn?

According to Song Yiyan's character, how could she tolerate Liu Manshan living with her?

Unless......

She also has a back-up move.

Song Yumei's eyes narrowed slightly, "In other words, since that day, you and Liu Xiaofang have been living together, and they are living together peacefully?" ”

"Hmm." Zhou Yan nodded, "So I said, Liu Xiaofang is quite strange, and his mind is a little incomprehensible." ”

She originally thought that the next cohabitation life would definitely be chickens and dogs.

After all, Song Yiyan didn't think about letting them live in it from the beginning.

Unexpectedly, Song Yiyan didn't embarrass them anymore.

Even Liu Manshan was surprised.

"When did you move here?"

Zhou Yan thought for a moment, "It's Wednesday." ”

Song Wu said quietly: "In other words, you have only lived together for three days, and Liu Manshan has an accident?" ”

"Hmm." Zhou Yan continued: "Fortunately, I wasn't at home that day, otherwise, that murderer would definitely kill me too!" ”

"When did you go out yesterday?" Song asked asked.

"It was about ten o'clock in the morning, and I didn't pay attention to the specific time."

Song Wu's red lips opened lightly, "When you left, was Liu Xiaofang at home?" Did she have any conflict with Liu Manshan? ”

"She seems to be at home," Zhou Yan recalled, "and when I left, I heard who she was talking to on the phone, as if she was still discussing what to eat at noon." Anyway, when I left, nothing abnormal happened to them, but after I left, I don't know if it happened! ”

Hearing this, Song Wu frowned slightly.

Why did Song Yiyan call Zhou Yan before leaving?

Can it be understood that she deliberately let Zhou Yan hear these words?

Thirty minutes later, Zhou Yan came out of the interrogation room, she was very nervous, "That little comrade, I answered all the questions you asked seriously, you, your police station shouldn't dig deep into my life, right?" ”

Song Wu looked as usual, "Keep the phone open after you go back, don't leave the capital casually, we will contact you at any time." ”

"Okay." Zhou Yan nodded, "Little comrade, don't worry, I will fully cooperate with your work!" So, then I can go now, right? ”

"Let's go."

Hearing Song Yan's words, Zhou Yan was relieved and immediately turned around and walked out the door.

Looking at Zhou Yan's back, Sister Ling walked up to Song Yan's side, "Miss Song, this is Zhou Yan's personal information, take a look." ”

Song Wu took over Zhou Yan's personal information.

After looking at it carefully, Song Wu continued: "Officer Zhao, I want to see Liu Manshan's body. ”

"Yes." Sister Ling nodded, "You come with me." ”

Liu Manshan's body is now in the forensic autopsy room.

It's summer though.

But the forensic department is still very infiltrating.

Sister Ling walked over with Song Wu, "Team Zheng, this is Miss Song." ”

Yu Luo explained: "It's the Miss Song who helped decipher the video last time." ”

Team Zheng is an old forensic doctor for many years, with a kind face, who was in charge of Liu Sisi's case before, and originally thought that Liu Manshan was the murderer, but he didn't expect that there would be such a big reversal later.

Therefore.

Song Wu has also become a myth in the bureau.

After all, the video deciphered by Song Wu was a problem that the technical department could not solve, and at that time, they almost sent the watch to the original factory to deal with it.

Fortunately, Song Wu appeared.

It's just that what Sister Ling brought Song Wu to the Forensic Department today?

Little girl's family.

Not too unlucky?

The Forensic Department was full of corpses, and they were all dead and unknown corpses, so they were all people related to the case.

"Hello Miss Song, I have admired my name for a long time!" Team Zheng took off his gloves and shook hands with Song Wu.

He touched corpses all year round, and it would be too rude to shake hands with gloves.

Song Wu stretched out her hand to shake hands with Team Zheng, her eyebrows were faint, "Team Zheng is too elevated to me." ”

Sister Ling spoke at this time, "Team Zheng, Miss Song wants to see Liu Manshan's body, is it convenient now?" ”

Hearing this, Team Zheng's eyes widened, as if he didn't expect Song Wu to want to see the corpse.

Are all the little girls so bold now?

"Look at the corpse?" Team Zheng asked with some uncertainty.

"Yes." Sister Ling nodded.

Team Zheng looked at Song Wu, "As long as Miss Song is not afraid, she can do it at any time." ”

"Trouble Team Zheng to lead the way."

Team Zheng continued: "Miss Song, Liu Manshan has a total of more than 20 wounds all over his body, his face is hideous, and his appearance may not be as peaceful as you imagined, or even scary, are you sure you are mentally prepared?" ”

Even if Song Wu has a talent for computers, she is just a teenage girl.

Don't talk about little girls!

I'm afraid that even many big men don't dare to look directly at the dead!

Especially the murder victims with hideous faces.

Team Zheng has worked in the forensic department for many years, and has seen many relatives of the deceased who were frightened and fainted when they saw the deceased's remains.

"Hmm." Song Wu nodded slightly, "Don't worry." ”

Team Zheng led the way in front.

Because the air conditioning inside was sufficient, as soon as I opened the door of the dissection room, a gust of cold wind rushed towards my face, and there was a faint strange smell.

After all, the autopsy room is a place where corpses are stored all year round, and it is not ventilated, and after a long time, a corpse smell is formed.

Team Zheng, who has been in contact with corpses all year round, has long been immune to this smell, but for Song Wu and Sister Ling, this smell is also very pungent, even if they wear thick masks, they can still do it

When I walked inside, I heard the voices of several forensic doctors.

It's all jargon, and it's hard for a layman to understand it.

"Chaoyang, Zifeng, Xiao He, the three of you put aside the things at hand."

Hearing this, the three of them looked up, "Team Zheng." ”

Team Zheng continued: "This is Miss Song, she and Officer Zhao want to see Liu Manshan's body. ”

The three of them looked at Song Wu, their eyes full of curiosity.

Chu Chaoyang looked at Sister Ling with a smile, "Sister Ling, are you a newcomer to your team?" ”

Sister Ling said: "Miss Song is an expert I specially invited. ”

"Miss Song is also studying forensic medicine?" Hearing this, not only Chu Chaoyang was surprised, but also Su Zifeng and He Dongdong were also very surprised.

It's all because Song Wu looks too young.

Although Song Wu was wearing a blue sterilization suit and a mask, she could still be seen from those good-looking peach blossom eyes, she was not very old, at most seventeen or eighteen years old.

Team Zheng explained: "Miss Song is the computer god who deciphered Liu Sisi's case last time. ”

Hearing this, the eyes of the three of them immediately appeared with a light of worship.

I just heard that the great god is very young and very beautiful, but I didn't expect the great god to be younger and more beautiful than I imagined.

Even if you wear an isolation suit, you can't hide that noble temperament.

He Dongdong immediately asked, "Does Miss Song have a boyfriend?" ”

Sister Ling was speechless and said, "Why are you talking so much, take us to see Liu Manshan's corpse." ”

He Dongdong immediately straightened his expression, "Sister Ling, this way." ”

Song Wu and Sister Ling and Team Zheng followed in He Dongdong's footsteps.

Several corpses covered with white cloths were parked in the autopsy room.

He Dongdong led several people to one of the corpses and stopped.

"This is Liu Manshan's corpse," He Dongdong did not forget to remind before lifting the white cloth: "Miss Song, you should be mentally prepared." ”

Sister Ling had already seen Liu Manshan's corpse, so she was naturally not afraid.

Therefore, the person most likely to faint here is only Song Wu.

After all, Song Wu is so young.

She may not have even seen a dead person, let alone a horrific murder victim!

Song Wu nodded slightly.

He Dongdong directly lifted the white cloth.

Just when everyone thought that Song Wu would scream in fright, Song Wu was not only not afraid, but walked to the corpse and checked the corpse's mouth and nose.

Calm to the extreme.

There was no look of fear between Qingjun's eyebrows, as if what was in front of her was not a terrible corpse, but a beautiful landscape painting.

Her reaction surprised everyone.

No one expected that Song Wu would be so calm.

Even Team Zheng was surprised by Song Wu!

He has worked in the forensic department for so many years, and it is the first time he has seen such a bold girl.

Song Wu carefully examined the injuries on Liu Manshan's body.

Liu Manshan has more than 20 scars on his body.

But there was only one real fatal wound.

That's the big artery in the neck.

After examining all the injuries, Song Wu looked at Sister Ling, "The murder weapon is not only the kitchen knife. ”

"How?"

As soon as these words came out, not only Sister Ling was a little surprised, but even Team Zheng and others from the Forensic Medicine Department were surprised.

After all, even they didn't find out that Liu Manshan had other scars on his body.

Song Wu pointed to Liu Manshan's arm and said: "The injuries here are from shallow to deep, the shallow places are only a few millimeters, and the deep places are five centimeters, it is obvious that they are quickly cut with a fruit knife or utility knife, if it is cut directly with a kitchen knife, the wound should not present this situation." ”

The most important thing is that the other cuts on Liu Manshan's body are all deeply visible, but there is no one here.

"Or maybe he dodged?" Sister Ling said.

If you dodge, the kitchen knife won't cut so deeply.

Song Wu nodded, "Liu Manshan did dodge, but he dodged not with a fatal kitchen knife cut, but from a scratch on his arm." In addition, the force of a kitchen knife is different from that of a fruit knife, and the blade of a kitchen knife is much longer, and if it is a kitchen knife, even if it is dodged, the incision will be deeper and rougher. The fruit knife is sharper, and the wound will be much shallower. ”

After speaking, Song Wu continued: "Liu Manshan has a total of twenty-two wounds on his body, among which the cut on his neck is the most serious, almost fatal!" The cervical vertebrae were almost cut off, indicating that the suspect was quick and ruthless, and Liu Manshan cut the suspect without any defense! If the suspect had done something to Liu Manshan before this, then the scratches on his body would definitely be more than just his arm! He will definitely dodge again, but Liu Manshan does not. Therefore, I speculate that after the suspect slashed at Liu Manshan's neck, Liu Manshan had no ability to fight back and fell directly to the ground, so the suspect could successfully cut down more than 20 knives in the back! The suspect knew that Liu Manshan would not survive, but he still slashed so many knives one after another, which shows that he hates Liu Manshan very much. ”

Hearing this, Team Zheng, Su Zifeng, He Dongdong and others all nodded.

None of them expected that the young girl in front of them would be so professional.

Moreover, he is even more calm in the face of dead bodies.

She has a real composure and sophistication that her peers don't have, like a battle-hardened killing god.

It's daunting.

Hearing this, Sister Ling frowned slightly.

"If this is the case, it means that before the suspect made a move, Liu Manshan had a conflict with someone!"

If these two people were the same person, Liu Manshan would definitely be vigilant, and the suspect would not be fatal with a single knife.

So.

These two are not alone.

Song Wu bowed slightly, "So to speak." Moreover, I think that this person who used a fruit knife to cut Liu Manshan must know something. ”

"Could it be Zhou Yan?" Sister Ling then asked.

"There is this possibility," Song Wu said while inspecting Liu Manshan's body: "Actually, Zhou Yan's words must not be believed, nor can they be fully believed. Under normal circumstances, a woman, even if she is engaged in a special profession, should not have sex with another man without her husband knowing that she has only been in a relationship with her newlywed husband for three days. In particular, she still wants Liu Manshan's money. ”

Since Zhou Yantu Liu Manshan's money, he should please Liu Manshan, instead of doing things that are sorry for Liu Manshan.

Even if Zhou Yan couldn't bear the loneliness, he wouldn't do such a stupid thing.

Sister Ling nodded, feeling that what Song Wu said was very likely, "I'll have someone call Zhou Yan to the police station immediately." ”

"Don't let her come just yet." Song Wu spoke softly.

"Why?" Sister Ling asked.

Song Wu's subordinates continued to inspect the corpse, "Now all this is just my guess, if I call her over rashly, it will startle the snake." The most important thing right now is to find more ......"

Before she finished her sentence, Song Wu felt that something was wrong.

She touched something hard in Liu Manshan's pocket.

Feel it out and take a look.

It's a black button.

Song Yu carefully observed the black button, and her red lips opened lightly, "Is there a magnifying glass?" ”

"Yes." Su Zifeng immediately picked up the magnifying glass and handed it to Song Wu.

Under the magnification of the magnifying glass, you can clearly see that there are two more drops of blood on the button.

Seeing this, Su Zifeng was very excited and said: "Will this button be the physical evidence left by the murderer!" Maybe the bloodstains on it are the murderer's! ”

Song Wu put the buttons into a transparent ziplock bag, and then carefully checked Liu Manshan's clothes.

Liu Manshan wore a T-shirt with no buttons on his upper body, and slacks on his lower body with no buttons.

So.

This button must have been left by the suspect.

Song Wu didn't expect that there would be such a harvest, so she handed the ziplock bag to Sister Ling.

Sister Ling took the ziplock bag, "I'll have someone identify the bloodstains and fingerprints on the buttons right away." ”

"Hmm." Song Wu nodded slightly.

Song Wu stayed in the autopsy room and continued to examine Liu Manshan's body.

She gently pinched Liu Manshan's mouth open and examined her mouth.

When people are persecuted, they will do everything they can to leave evidence to the outside world.

So, there is a saying that corpses can also speak.

Liu Manshan drinks and smokes all year round, resulting in yellow cigarette stains on his teeth, which does not look elegant.

I didn't find anything unusual in my mouth.

At this moment, Song Wu's gaze fell on Liu Manshan's left hand.

Under the illumination of the light, Liu Manshan had a shiny silk thread on the nail cover of his left ring finger.

Song Wu picked up the tweezers, removed the thread on the nails, and observed it carefully with a magnifying glass.

"Is this a strand of hair?" Su Zifeng leaned over and asked curiously.

"It's not." Song Wu shook her head slightly, "Although it is very similar to a hair strand, human hair will not reflect under the light, this should be a man-made fiber wig." ”

Man-made fibers contain polypropylene, which reflects light when illuminated by light.

Song Wu put this wig-like thing in a ziplock bag, took it to the identification department, and went to the identification department together.

Team Zheng accompanied Song Wu over.

Looking at the back of Song Wu leaving, Su Zifeng folded her hands together and said with admiration on her face: "Miss Song is really sassy!" I decided that from now on, Miss Song will be my idol! ”

Seeing Song Wu and Team Zheng coming, Sister Ling immediately asked, "Miss Song, is there anything new to discover?" ”

"Hmm." Song Wu nodded slightly, and handed the things she found to Sister Ling, "Identify whether this is hair or a wig." ”

"Okay."

The results won't come out so quickly.

You need to wait about 24 hours.

Sister Ling looked at Song and continued, "Miss Song, I will inform you as soon as the results come out." ”

"Okay." Song Wu bowed slightly, "By the way, Officer Zhao, can you send me the address of Shen Tong's house?" ”

"Yes, I'll send you WeChat right away." Realizing that Song Wu might be looking for something, "Miss Song, if you need our help, you can contact me at any time!" ”

"Hmm."

Later, Song Wu came to the police station again and continued to wait for Mrs. Song.

Not much.

Mrs. Song and the lawyer came out of it.

"Grandma." Song walked over and took Mrs. Song's arm, hiding her merit and fame.

"Sister-in-law," Mrs. Song's expression was very ugly, "Liu Xiaofang is really vicious, over the years, I have underestimated her, and she has not left any way back for Boyang!" ”

Mrs. Song doesn't like Song Boyang.

But this does not mean that she can ignore the reputation of the Song family.

It doesn't mean that she can let Song Yiyan, the white-eyed wolf, trample on the Song family, and let Song Boyang be a scapegoat for Song Yiyan in vain.

Mrs. Song always felt that she saw Song Yiyan very thoroughly, felt that she was scheming, and she was not a good person, but she never expected that Song Yiyan would be able to design such a perfect game.

It's horrible!

If it weren't for the fact that she knew Song Boyang very well, she would almost think that Song Boyang would be the murderer.

Even the lawyer thinks that Song Boyang's chances of turning over this time are very slim.

Song Wu comforted Mrs. Song softly, "Grandma, justice may be late, but it will never be absent." I believe it's just a matter of time. ”

"Hmm." Old Lady Song nodded, "I believe it too!"

One old and one young got into the car.

Lawyer Ho also followed.

After getting into the car, Mrs. Song continued to discuss the case with Lawyer He.

Mrs. Song was very puzzled and said, "Lawyer He, you say, why is there Boyang's fingerprint on that kitchen knife?" Boyang didn't hold a kitchen knife at all! If it was Liu Xiaofang who killed the killer, how did she do it? Could it be that some kind of glove was used that could copy other people's fingerprints? But at present, there should not be such high-tech gloves in Huaguo, right? ”

Even if there was such a high tech, it would not have been designed.

If it is really designed, then everyone can wear gloves to sin, and the world will be in chaos!

Obviously, there could be no such gloves at all.

Lawyer He frowned slightly, he suspected that Song Boyang was lying.

After all, Song Boyang had picked up a kitchen knife to kill Liu Manshan before, and he had a motive to kill, and the motive was very sufficient.

Moreover.

Song Boyang has not yet had any witnesses.

But Song Yiyan certified that there was physical evidence.

At this moment, Song Wu seemed to suddenly think of something, and then said, "Grandma, I forgot to take something, you and Lawyer He go back first." Uncle Ma, stop the car. ”

Old Lady Song looked at Song Aunt, "Sister-in-law, what are you going to get here?" Why don't you go with your grandmother? ”

"No need, grandma, I still have some things to deal with after I finish taking things, you go back first."

"That's okay," Mrs. Song then instructed, "you pay attention to safety." ”

"Hmm."

The car slowly stopped on the side of the road.

After getting out of the car, Song Wu trotted back to the police station.

Seeing her go and return, Sister Ling immediately walked over, "Miss Song, why are you back again?"

"Officer Zhao, I heard that my little brother's fingerprints were extracted from that kitchen knife, right?" Song asked asked.

"Yes." Sister Ling nodded.

Song Wu continued: "Can I take a look at that kitchen knife?" ”

"Come with me." Although it is very important physical evidence, evidence has been collected and fingerprints have been identified, so there is no problem for Song Yu to take a look at it at this time.

Sister Ling took Song Wu to the evidence room.

Song Wu saw the blood-stained kitchen knife.

Although the blood stains have dried now, it is still terrifying.

Through the glass case, Song Wu looked at the kitchen knife very carefully, and then she said softly, "No, this is not the real murder weapon." ”

"How?" Sister Ling asked.

Song Wu continued: "A kitchen knife that can directly cut off human bones, the knife edge must be very sharp, not to mention, Liu Manshan has a total of more than 20 wounds all over his body, and each of them hurts the bones, as we all know, if the hardness of steel is 7-8, then the bones of human beings can reach 4-5, and the bones of adults will be even harder." People who use kitchen knives often should know that no matter how sharp a household kitchen knife is, if you stomp on the bone, the edge of the knife will become dull. In the same way, if the suspect used this kitchen knife to cut Liu Manshan so many times, then the knife edge would definitely be damaged, but the edge of this kitchen knife is still very sharp! It doesn't look like a kitchen knife that has cut bones. ”

Hearing this, Sister Ling frowned slightly, and immediately asked someone to bring a new kitchen knife and some pork bones.

In order to avoid errors, Sister Ling specially asked people to buy the same kitchen knife.

Sure enough, after trying to chop the pig bone a few times, and before even ten strokes, the knife edge was damaged to an unknown extent, and the knife edge was becoming dull.

Song Wu's red lips opened lightly, and her tone was a little light, but she was loud.

"Liu Manshan's time of death was between 19 and 22 o'clock. Assuming that Liu Xiaofang is the murderer, then after the killing, she must not only deal with the real murder weapon in time, but also arrive at the downstairs of Building 10 on time at 9 o'clock, the power went out that night, and it takes about 10 minutes for her to take the stairs to the first floor, and it will take five minutes to trot at the earliest, and it will take two minutes to go down from the upstairs to Building 10. In this way, she is only 110 minutes left to kill and deal with the scene and throw away the murder weapon! 110 minutes may seem like a lot, but it's not easy to get it done. Therefore, the real murder weapon must have been disposed of on her way to Building 10, I checked, from Building 3 to Building 10, there will be a total of 3 garbage rooms, and these garbage rooms are unified to recycle garbage at exactly 9 o'clock. ”

------Off topic------

Good morning, little fairies, duck~

The truth is peeling back layer by layer.

There will be two shifts today.

Momua! (*╯3╰)
