In the testing room, Forensic Doctor Liu still agreed with the views of the two apprentices.

Especially Gu Chen, as a non-legal doctor, Forensic Liu is quite satisfied with the questions raised by Gu Chen and his own unique views.

"Yes, if the skin color changes along the back and the body is lying on its back, it is impossible to determine whether the body has been moved. ”

"And if the posture matches the pattern of the corpse, it is possible that the body was discarded immediately after the victim's death, or more than 8 hours after the victim's death. ”

When Lu Weiwei heard Forensic Doctor Liu's words, she also asked thoughtfully: "Then if the deceased is face-down for three or four hours, and then is moved to a supine position, will there be local corpse spots on the front and back of the corpse?"

"Yes. Gu Chen explained this problem for Forensic Doctor Liu, saying: "Because dead people don't move on their own, if the corpse pattern suggests that the victim was placed in two different positions in the first 8 hours after death. ”

"As a medical examiner, it is possible to conclude that someone has moved a body within two to six hours. ”

Therefore, through the pattern of corpse spots, it is possible to determine whether the deceased has been moved, and to calculate the approximate time point. ”

Looking back at the corpse on the testing table, Officer Wang asked Forensic Doctor Liu, "So you are waiting?"

Forensic Doctor Liu nodded slightly: "It will take some time, because the probability of a person falling from the stairs to death is very small, of course, you can already be sure that it is the scene of the first crime, so there is nothing to say, just say that the probability of an accident is also in the past." ”

"No, it's better to test it. Gu Chen interrupted Forensic Doctor Liu's remarks and said, "Although I have seen the scene of the crime, judging from the traces of the steps at the scene, there are actually many suspicious points. ”

"Suspicious?" Gao Chuanfeng frowned slightly and asked Gu Chen, "What do you mean?"

"Bloodstains. Gu Chen said.

Gao Chuanfeng didn't quite understand, and shook his head: "Can you be more specific?"

Gu Chen hesitated for a few seconds before he raised his head and said, "Although the marks on the steps are indeed caused by blood, and falling down the stairs from the stairs is indeed prone to collisions in these places. ”

"But I found that the blood stains on the steps were not natural, because it was the first time I had encountered such a situation, so I was not sure whether the blood stains were caused by the fall or if someone had brought them up later. ”

"Uh......"

Hearing Gu Chen's words, Gao Chuanfeng was stunned for a moment, and then said weakly: "But when I look at the scene, it is indeed the appearance of the fall from the building, and you didn't say that the blood stains on the steps are suspicious before." ”

"Yes, I didn't, that's because I'm not sure. Gu Chen then took out a bloody napp wrapped in a transparent forensic bag from his carry-on bag.

"This is the blood I simply extracted from the steps of the site, because the blood stains on the steps at that time were already in a coagulated state, so I soaked the steps with water and adsorbed some of the diluted blood with a paper towel. ”

Forensic Doctor Liu took the sample provided by Gu Chen, then nodded slightly, handed it to Gao Chuanfeng, and said, "Xiao Gao, you test this sample to see if it matches the blood on the deceased's body." ”

"Good. "What else can Takakawa Kaede say?

If the master wants to test, he will naturally do it obediently.

With the sample in hand, I returned to the workbench and began to use the instrument for testing.

Forensic Doctor Liu reminded: "It will take some time for the test to be compared, have you had dinner?"

"Nope. Lu Weiwei was the first to shake her head.

"Then I'll call my colleague and ask them to bring five cents of food, and we'll have some random food in the testing room?"

Lu Weiwei nodded fiercely: "That's great." ”

Although I was examining the corpse and eating the food, I felt that the food suddenly did not smell good.

But fortunately, there have been several experiences of eating in the testing room of the technical department, which has made Lu Weiwei have long been used to it, and it is not a problem to even look at the corpse with food.

This is going to be the same as before, it is estimated that Lu Weiwei herself would not dare to think about it.

But now following Gu Chen, I feel that I have become bolder.

Even Yuan Shasha, who once vomited when she saw a corpse, seemed to be slowly transforming.

"This may be growth, right?" Lu Weiwei said secretly in her heart.

......

......

Not long after, a police officer brought five meals, and everyone took them to the next lounge to eat.

At this time, Gu Chen received a call from He Junchao.

Since he was eating, Gu Chen directly put it on the table and clicked on the hands-free.

"Senior Brother He, has the phone been unlocked successfully?" asked Gu Chen.

He Junchao smiled: "It's a little meaning, this kind of unlocking is sprinkled with water for me." ”

"Then did you find anything?" Gu Chen asked as he ate.

"Of course there is, otherwise what are you doing on the phone?" He Junchao also looked confident, and said: "I helped you check Xiong Li's mobile phone and found a very interesting phenomenon." ”

"Is it Jiang Hua's message to her and missed the phone?" asked Lu Weiwei on the side.

He Junchao on the other end of the phone said with a smile: "That's right, Jiang Hua is really an old licking dog, in the first few days, I found that Xiong Li's missed calls to him averaged more than 20, and in the past two days, it has become five or six, and there are a lot of text messages, all asking where she is." ”

"Has Xiong Li been in contact with anyone else in the past few days?" asked Officer Wang.

He Junchao smiled: "Of course, there have been several phone numbers with the phone number showing Zhou Fan, and just this morning, Xiong Li also contacted Zhou Fan." ”

"Then Zhou Fan, do you want to investigate?" Lu Weiwei asked Gu Chen.

"Definitely. Gu Chen put down the chopsticks in his hand, and couldn't help but say: "Zhou Fan, this person, how can he be regarded as a key person, maybe he can explain the relationship between himself and Xiong Li, as well as Xiong Li and Jiang Hua." ”

Moreover, Xiong Li is not a native of Jiangnan, if you want to contact her relatives and friends, Zhou Fan, as her former alumni and lover, of course she must let him know. ”

Gu Chen knew very well that now being able to find Zhou Fan from Xiong Li's mobile phone was a breakthrough in itself.

At least Gu Chen also wanted to know if the situations that Jiang Hua dictated in the police car were real?

And what kind of character is this Zhou Fan? Gu Chen is still hard to say.

At least Zhou Fan is a heinous liar in Jiang Hua's mouth, and of course he may have personal emotions in it.

In the mouth of Zhang Li, Zhou Fan's former university class teacher, he is also a cultural and sports activist and a figure of the school.

In general, the reviews of different characters are mixed.

If Gu Chen wanted to understand Zhou Fan, he would definitely have to meet him.

Seeing that Gu Chen didn't reply for a long time, He Junchao on the other end of the phone asked, "Gu Chen, is there anything else to do here?" ”

"Yes, you send me Zhou Fan's phone number, and then you can get off work. Gu Chen replied very briskly.

The two exchanged a few words of greeting, and then both hung up the phone.

It didn't take long for Gu Chen's mobile phone to ring, and He Junchao sent Zhou Fan's phone number.

Gu Chen then dialed according to the phone number.

Soon, the phone rang.

A hoarse male voice said, "Hey, who are you?"

"I'm Gu Chen from the Third Criminal Investigation Group of the Furong Branch, are you Mr. Zhou Fan?" Gu Chen asked him directly.

The man on the other side seemed to be taken aback, and his tone became a little polite: "It turned out to be the police?

"Do you know Xiong Li?" Gu Chen asked him.

The man said, "Yes, what's wrong with her?"

"I accidentally fell down the stairs this afternoon, and the person is gone. ”

"What?

As soon as Gu Chen's voice fell, the man on the other end of the phone seemed to become anxious.

Gu Chen could feel his rapid breathing from the phone and through the screen.

The man asked Gu Chen a little frantically: "Comrade policeman, don't joke with me, she was fine yesterday, why is she doing it today?"

"I didn't lie to you, I hope you can come to the technical department of the city bureau yourself, and now, we will wait for you here. ”

Gu Chen also told Zhou Fan the address and was going to talk to him here.

Zhou Fan also agreed quite happily, and replied: "Okay, you wait for me there for a while, I'll come over right now." ”

Hanging up the phone, Gu Chen glanced at his phone, threw it aside, and continued to pick up chopsticks to enjoy dinner.

......

......

Minutes and seconds passed.

Gao Chuanfeng and Forensic Doctor Liu also came out of the testing room.

Lu Weiwei immediately reminded: "Forensic Doctor Liu, Gao Chuanfeng, hurry up and come over for dinner, if you don't eat, the food will be cold." ”

originally thought that Gao Chuanfeng and Forensic Liu would be very positive, but the two of them were listless.

Gu Chen, who saw the problem, hurriedly asked, "What's wrong?"

"There's something wrong with the blood. Forensic Doctor Liu sat down beside Gu Chen, took the chopsticks handed by Gu Chen, and gently opened the lunch box.

"What do you mean...... Blood mismatch?" Gu Chen seemed to have guessed something, and asked him softly.

Forensic Doctor Liu nodded silently: "We have repeatedly compared and confirmed that the blood sample you collected on the stairs of the corridor does not match the blood sample on the deceased Xiong Li. ”

"What? How can it not match?"

Before Gu Chen could speak, Officer Wang was a little unsettled in an instant.

"No, didn't this man fall down the stairs? And I've seen Xiong Li's wounds, and they were all from falling down the stairs, I can see that. Lu Weiwei also expressed puzzlement.

Wondering why blood samples don't match?

If they don't match, how are these wounds caused?

Gu Chen was also suspicious: "Could it be that the corridor is not the scene of the first crime? Xiong Li's body is very likely to have been carried by someone?"

"You're right. Gao Chuanfeng, a forensic assistant who was eating chicken legs, couldn't help but complain: "According to the time calculation, we have also compared the pattern of corpse spots. ”

"Didn't we discuss it before: If the deceased is moved face down for three or four hours and then moved to a supine position, will there be local spots on the front and back of the body?"

"Yes, yes. Lu Weiwei nodded silently.

"Because...... Because dead people don't move on their own, there are such corpse spots on the front and back, indicating that the corpse must have been moved. ”

"And in terms of time, the deceased died an hour before you received the report, so no one found out within an hour?"

Gao Chuan Feng was eating his meal, and his speech seemed a little slurred.

However, this reminded Gu Chen.

Gu Chen nodded silently, and said lightly: "If this is the case, then it means that the corridor we saw is actually not the scene of the first crime at all." ”

"What do you say about Xiong Li's wound?" Lu Weiwei also raised her own questions and asked: "Xiong Li's wound is obviously a bruise, and from various angles of the body, it may be a fall down the stairs, and the impact marks on the staircase steps are all consistent with the characteristics of these wounds." ”

There was a sudden silence for a few seconds, everyone looked at each other, and everyone was thinking seriously.

Xiong Li...... It's a fall from a staircase, yes. Gu Chen's words suddenly broke the silence.

Gao Chuan Feng was puzzled, and just wanted to ask.

As a result, Gu Chen directly said: "But the scene where she fell from the building is not the unit we saw, it may be in another location, and the person who carried her body is completely laid out according to the scene of another location." ”

"Including Xiong Li's distorted state when she fell, and the marks left by the impact on the steps, they were copied from another location entirely. ”

"Shine...... Copy it over?" Hearing Gu Chen's words, Forensic Doctor Liu was stunned, and the whole person was also stunned.

Officer Wang hurriedly asked, "In that case, Xiong Li still fell from the building?"

"That's right. Forensic Doctor Liu put down his chopsticks, and his whole face looked a little dull: "I examined Xiong Li's body, her femur was fractured and pierced through the skin, we call this situation a complex fracture." ”

"If the broken bone does not pierce the skin, although the condition is relatively simple, it is still potentially life-threatening. ”

And because the thigh area is likely to have several liters of blood, although it does not bleed on the outside, it is enough to put Xiong Li into shock and even die. ”

Seeing that everyone was looking at him, Forensic Doctor Liu paused and continued to explain in detail: "This external sign is that the thigh is severely swollen, and the diameter is much thicker than the other leg. ”

"The thigh may also have a blue-black skin due to internal blood, and our autopsy found that there was a large amount of blood in the thigh, which can basically determine that the cause of death is fracture and internal bleeding. ”

"And we have examined the wound in detail, and we have not seen that it was a blunt force injury, so I conclude that it is very likely that the deceased Xiong Li fell from the corridor and died. ”

"That's right. Gu Chen suddenly stood up and walked back and forth around everyone.

"It is very likely that Xiong Li died in another location, and the cause of death was a fall from the building, but someone didn't want us police to find out, so they moved Xiong Li's body to the scene we saw. ”

"Moreover, according to the scene of the incident at that time, this person simulated and restored the traces of several impact sites, and even used other blood to forge several impact marks to mislead us. ”

The scene was quiet again for a few seconds......

Everyone looked at each other, as if they felt terrified by thought.

Xiong Li accidentally falls down the stairs.

The body was skillfully carried.

The scene was carefully camouflaged.

The combination of these conditions inevitably makes people feel that there seems to be a big secret hidden behind the corpse carrier.

And just when everyone was figuring out the intentions behind the corpse movers, a phone call was made to Gu Chen's mobile phone.

Gu Chen directly swiped the answer button: "Hey." ”

"Is it Officer Gu? I'm Zhou Fan you just called. ”

"Zhou Fan?" Gu Chen looked out of the door and strode towards the passage: "Where are you now?"

"It's in the technical department of the city bureau, but there are a lot of rooms here, I don't know where you are now?"

"You look straight ahead. Gu Chen stood in the passage and raised his hand at Zhou Fan who was not far away.

"Oh, I see you. Seeing that Gu Chen was in front, Zhou Fan hung up the phone and ran over in small steps.

When he came to Gu Chen, Zhou Fan was already out of breath, and it seemed that he was in a hurry along the way.

"Officer Gu, where is Xiong Li?"

"Testing room. ”

"Then can I see her now?" Zhou Fan asked.

Gu Chen hesitated for a moment and shook his head: "Not yet." ”

"But ......"

Before Zhou Fan could speak, Gu Chen directly grabbed his arm and walked to the periphery of the testing room.

Through the transparent glass, Xiong Li's body was lying on the testing table.

Gu Chen also reminded: "It may take some time for you to go in and disinfect it, but I have a lot of things to ask you now, so you have to cooperate with me first." ”

Zhou Fan seemed to be very depressed, lying on the glass, looking at Xiong Li's body on the testing table, and couldn't help but shed a few tears in his eyes.

"How can this be?

Gu Chen took a deep breath, and also comforted and said, "Please mourn, the person is dead, this is already a fact." ”

"How did she die?" Zhou Fan asked as he glared at Gu Chen.

Gu Chen shrugged: "Fell from the stairs and died of internal bleeding." ”

"Fell to death?" Hearing Gu Chen's words, Zhou Fan's eyes were full of incredulity.

Gu Chen nodded slightly: "Although I don't like to admit that this is the case, but ...... That's just the way it is. ”

"Impossible, how is it possible? How could a good person fall to his death from the stairs?" Zhou Fan seemed to be still indulging in the impossible rhythm and couldn't extricate himself.

But Gu Chen didn't have time to spend time with him here, so he reminded him directly: "Mr. Zhou Fan, let's go in and talk, okay?"

Zhou Fan raised his head slightly, and said, "Okay." ”

Gu Chen took Zhou Fan to rest.

At this moment, everyone has also wiped out dinner and is cleaning up the table.

Gu Chen arranged for Zhou Fan to sit in an office chair, while he sat opposite him.

After turning on the law enforcement recorder, Gu Chen aimed it at Zhou Fan and placed it on a steady pile.

Officer Wang and Lu Weiwei also surrounded one after another.

"Your name is Zhou Fan?" Gu Chen took out the transcript and looked up to ask him.

"Hmm. Zhou Fan nodded slightly.

"Report the ID number. Gu Chen said.

Zhou Fan did as he was told, and informed Gu Chen of his personal information in accordance with the process.

After completing the basic registration, Gu Chen directly raised his head and asked Zhou Fan: "Xiong Li and you are the same junior sister, right?

Hearing Gu Chen's words, Zhou Fan was suddenly stunned, and his eyes stared at Gu Chen incredulously.

......
