In the virtual space, Gu Chen simulated the scene of Xiong Li falling down the stairs.

All wound sites coincide with the bloodstains in the corridors.

From this point of view, it is basically possible to conclude the accuracy of the fall.

But Gu Chen still has his own new ideas......

If you stumble, it can happen in a variety of ways.

It is difficult for ordinary people to fall to their deaths in the hallway.

In other words, the probability is extremely low.

But there is another possibility, and that is to be disturbed by the outside world.

Unconsciously do some actions that could have been avoided.

It's like chatting with someone in reverse and unconsciously stepping on empty stairs.

Or...... Pushed down the floor?

These can happen.

Thinking of this, Gu Chen snapped his fingers again.

Soon, the lights overhead came on again, and they expanded in phases.

Gu Chen snapped his fingers again.

At this moment, above the floor, Xiong Li was communicating with a black figure.

Since Gu Chen didn't know who the other party was, this black shadow could only be set to X or an unknown person in the simulated space.

Hei Ying and Xiong Li walked downstairs together, passed through Gu Chen's virtual body together, and came to the last 13 steps of the floor.

At this time, the two were communicating.

In an instant, another argument broke out.

At this time, Xiong Li faced the black shadow on the stairs, and in the constant dispute between the two, Xiong Li's right leg suddenly stepped into the air, and one stumbled down the stairs, falling heavily into a twisted appearance.

Gu Chen checked the path of the fall just now, and all the impact sites lit up again at this moment.

As just now, this kind of fall can indeed meet the impact conditions.

Immediately afterwards, Gu Chen conducted a third simulation.

This time, while Xiong Li was arguing with the black shadow, the black shadow inadvertently suddenly pushed violently.

Unsuspecting, Xiong Li stumbled and fell down the stairs.

After a violent roll, the wound that Xiong Li hit could still match the location of the corridor.

"So, no matter which way you fall, it's actually possible?"

Gu Chen clasped his hands on his chest and hesitated for a moment.

"This is a simulation based on the known impact wound site of the staircase, although there are slight differences, but from the tumbling mode and the location of the impact degree, it actually meets the current conditions. ”

"In other words, there are indeed three possibilities for Xiong Li to fall from the building?"

Thinking of this, Gu Chen snapped his fingers.

Soon, a rainbow crossed in front of me.

When Gu Chen opened his eyes again, Lu Weiwei happened to walk cautiously in front of him.

"Senior Brother Gu, what do you think of the scene?"

"Falling from the building, what else can you see?" Gu Chen squatted down, looked at the bloodstains on the corridor, and couldn't help but shake his head and sighed: "This Xiong Li is too careless, how could a good person fall like this?"

Seeing this, Lu Weiwei also learned Gu Chen's squatting posture, leaned beside him and asked, "Then do you think it is possible for him to kill him?"

"It's hard to say. Gu Chen shook his head.

Lu Weiwei nodded silently: "That is to say, judging from the current situation, there is a high possibility of an accident, after all, Xiong Li should not have many friends here." ”

"Friend?" Gu Chen suddenly thought of something, and suddenly glanced at Lu Weiwei.

Lu Weiwei blinked her beautiful eyes, and her head couldn't help shrinking back: "What's the matter, Senior Brother Gu, what did you think of?"

"Zhou Fan, Jiang Hua, what do you think of these two people?" Gu Chen asked.

Lu Weiwei thought thoughtfully: "These two people, judging from the current situation, it's hard to say. ”

"Aside from the situation that Jiang Hua told us, let's just take Zhou Fan as an example, although he is the school figure in the mouth of the head teacher Zhang Li, after all, he has been separated from Xiong Li, and we don't know the situation after the two. ”

"Did he want Xiong Li to come to Jiangnan City with him? Or did Xiong Li feel incompatible with Jiang Hua and voluntarily came to Jiangnan City, we didn't figure this out. ”

But from the current point of view, Xiong Li lives alone, which means that she and Zhou Fan may not live together for the time being. ”

According to her own ideas, Lu Weiwei probably analyzed the situation of Zhou Fan and Xiong Li.

Gu Chen nodded slightly, feeling that it was in line with his expectations and judgment.

So he asked again: "What about Jiang Hua? What do you think of Jiang Hua?"

"This Jianghua...... I feel that the relationship with Xiong Li is definitely not ordinary. Lu Weiwei hesitated for a few seconds, and then said: "You think, he can take a long leave and rush all the way from Jiangbei to Jiangnan, just to find Xiong Li who has no clues." ”

"If you judge according to normal logic, how can he Jiang Hua be sure that he can find Xiong Li?

Xiong Li didn't answer his phone, didn't take the initiative to tell him where he was, and the key was that he didn't even have ticket purchase information. ”

"As far as these points are concerned, Jiang Hua's coming to Jiangnan City to find Xiong Li is understood as looking for a needle in a haystack, which is completely meaningless. ”

"Yes, you're right. Gu Chen stood up suddenly, and also calmed down and said: "From this point of view, it is very likely that Xiong Li will come to Jiangnan City to defect to Zhou Fan, and it is even more likely to hide from Jianghua." ”

"If you have to assume that this is a homicide incident and a suspect needs to come forward, it must be more likely to be Jiang Hua. ”

"What do you say?" Officer Wang, who had just finished collecting evidence at the scene, walked up to the two and said, "I have already contacted the technical department of the city bureau and asked Gao Chuan Feng to take the body away." ”

"Then I'll have to take another look. Knowing that as soon as the body was removed, many of the environments at the scene would change, Gu Chen still had a cautious attitude and continued to check the corridor to deepen his impression.

After completing all the operations, Gu Chen walked out of the unit building and let passers-by disperse to make way for a driving lane.

At this time, there are more and more people, and many people are talking about it.

At this moment, Gu Chen suddenly felt that another pair of strange eyes seemed to be looking at him beside him.

But when Gu Chen looked around, he found that there were passers-by all around, and those strange eyes disappeared again.

"Could it be that I'm dazzled?" Gu Chen frowned slightly.

"What's the matter, Senior Brother Gu?" Yuan Shasha walked up to Gu Chen and asked with a curious expression.

"Nothing. Gu Chen shook his head, as if nothing had happened.

Perhaps it's because the role of observation is increasing.

In the process of continuous experience accumulation and upgrading, the previous earliest skill level is now developing towards the level of master, or master+.

Although the skills have been improved, it has also invisibly brought some small troubles to himself.

For example, being too sensitive to the things around him, Gu Chen was deeply touched by this.

Hesitating to give way to the car, Gu Chen asked Officer Wang to park the police car in a vacant parking lot and give way to the passage.

And it didn't take long for Gao Chuanfeng to arrive with the police officers of the technical department, and everyone carefully carried Xiong Li's body into the car.

After completing the carrying work, Gao Chuanfeng ran over and asked Gu Chen, "By the way, Gu Chen, do you have any arrangements for this corpse?"

"First put it in the testing room of the technical department of the city bureau to see if there is anything suspicious. Gu Chen said.

"Then how can her family be contacted?" asked Takakawa again.

Gu Chen picked up the mobile phone wrapped in a transparent forensic bag and said, "The mobile phone is locked, I need to bring it back and ask He Junchao to help me unlock it." ”

"Okay then, keep in touch if you have any questions. ”

To be honest, Takakawa Kaede doesn't like to stay in crowded places for too long, he prefers to do research in a quiet testing room.

Maintaining order at the scene and escorting Gao Chuanfeng away, Gu Chen called the old lady Liu Guilian who called the police to his side.

"Grandma Liu, how long will she rent your house for this Xiong Li?"

"Well, two days. Liu Guilian said.

"Is she the only one who lives?" asked Lou again.

Liu Guilian nodded: "Yes, she lives alone." ”

"Then does she tell you what kind of work she does?" said Officer Wang, who also came over after dealing with the matter at hand.

Liu Guilian shook her head: "This is not clear, when she rented my house, she said that she was looking for a job and may develop in Jiangnan City in the future, so I saw that she was not bad, so I agreed to rent it to her." ”

"How did she contact you?" Gu Chen's law enforcement recorder was aimed at Liu Guilian, and the transcript in his hand was also recording rapidly.

Liu Guilian said truthfully: "At the entrance of our community, there is a bulletin board, like any notice, a notice of finding things, a rental and the like, you can post it up." ”

"When she called me, she found my rental information at the door. ”

Gu Chen nodded slightly, and asked again, "Then the house she rents, can you take me to see it?"

"Yes, but I have to go get the keys, and the spare keys are in my son's hands. Liu Guilian turned her head to find the strong man's son.

Gu Chen directly took out a bunch of keys wrapped in a transparent forensic bag, and asked the old lady: "This is found from the deceased Xiong Li, which key can open the door?"

The old lady Liu Guilian squinted her eyes, and after bowing down to look for it, she pointed to one of them and said, "This is it." ”

Gu Chen wore white gloves, gently removed the key from the lock, and said, "Then you can take us over now." ”

......

......

Everyone followed the old lady and walked up the corridor and came directly to the 3rd floor.

Then Gu Chen used the key in his hand to open the door smoothly.

After putting on the new shoe covers, Gu Chen was the first to walk into the room and check the situation in the living room.

This is a two-bedroom and two-living room, north-south transparent house, with average decoration and general furniture.

Judging from the overall layout of the house, it seems to be a bit old.

Liu Guilian's son followed Gu Chen into the house after receiving the foot cover handed by Yuan Shasha.

"This is it. The strong man said: "Originally, my mother lived here alone, but then my child was born, and my lover and I had to work, so I took my mother to the house to take care of the grandson, and this house was vacated and rented to others to earn some rent." ”

Speaking of this, the strong man couldn't help sighing: "But it's only been a few days since it was rented out, and this kind of thing happened, it's really unlucky." ”

"In the future, I will rent it to others, and it is estimated that the price will have to be pushed down. ”

"She didn't die in the room, what's not obscure?" The old lady Liu Guilian seemed to be very dissatisfied, and walked directly to the middle of the crowd:

"At the beginning, I said that it was empty and empty, and that you should not rent it out, but you didn't listen to it, and you had to earn the rent. ”

"But now it's okay, the tenant fell to his death at the entrance of the building, and now the neighbors know that it is my tenant, how do you say this house should be rented out in the future?"

The strong man was scolded by his mother to the point of incompleteness, and he was also embarrassed at the moment.

He glanced at Gu Chen, and said with a wry smile: "My mother is like this, the rent is thousands of yuan a month, and it can subsidize the family somewhat, but the old lady is stubborn and seems to be unwilling to rent." ”

"In the end, I was in the printing shop, printed a few rental contracts on 4A paper, and posted them on the bulletin board at the entrance of the community, and someone called her to ask her to compromise, but who would have thought so much at that time?"

"It's not that you're greedy for money. The old lady was so angry that tears were about to flow out.

Gu Chen hurriedly said safely: "Grandma Liu, you dissipate your anger, Xiong Li fell to her death at the top of the stairs, not in your house, so this house is fine." ”

"Really?" said her son at first, but Liu Guilian didn't believe it.

But now as soon as the police spoke, Liu Guilian's heart felt better.

Seeing this, Lu Weiwei also quickly nodded and agreed: "Yes, your house is fine, how should it be." ”

"Listen, listen to what the police say, don't be foolish when you're fine. Seeing that the two policemen spoke for themselves, the strong man also hurriedly agreed.

I feel that it is important to stabilize the old lady's emotions first.

At this time, Officer Wang, who had finished inspecting all the rooms, also walked up to Gu Chen and said, "I have already checked, and there is nothing suspicious in the room." ”

Gu Chen nodded slightly and asked the strong man, "How long have you rented this house to Xiong Li?"

"Three months. The strong man stretched out three fingers and said, "Originally, it was rented for half a year, but considering that she had just come to Jiangnan City, my mother relaxed the conditions and paid one for three." ”

But she only paid a month's deposit first, saying that the rest of the rent would be paid in a few days. ”

"Thinking that people might want to get used to it first, we agreed. ”

"Rent for three months?" Gu Chen frowned slightly, feeling that this Xiong Li would definitely not return to Jiangbei with Jiang Hua.

After all, the rent is paid for three months, which shows that people are determined to stay here.

In order to figure out the situation as soon as possible, Gu Chen asked Yuan Shasha to return to the Furong Branch with the unlocked mobile phone and ask He Junchao to help unlock it.

And he took Officer Wang and Lu Weiwei to the technical department of the city bureau together, ready to further check Xiong Li's body.

At this time, on the testing table, Xiong Li's body was wrapped in a white cloth.

Gao Chuanfeng was sitting on the testing table, cooperating with Forensic Doctor Liu, and the two seemed to be filling in the information.

Seeing that Gu Chen and his party arrived, Forensic Doctor Liu and Gao Chuanfeng did not leave their seats.

For the testing room, Forensic Doctor Liu has long regarded Gu Chen as his own, and his arrival is not surprising.

"How is Forensic Doctor Liu?" Gu Chen walked over and asked.

"Did she fall down the corridor?" forensic doctor Liu asked Gu Chen rhetorically.

Gu Chen nodded slightly: "That's right, judging from the situation on the scene, it is indeed the case." ”

"It's quite miserable, and when I scanned her body, I found that the fall caused her to shatter her femur, and it is very likely that she died of internal bleeding," said Forensic Doctor Liu. ”

Gu Chen hesitated for a moment and asked Forensic Doctor Liu: "If the bone did not pierce the skin, is there any visible sign that the cause of death is internal bleeding?"

Or...... If the deceased Xiong Li died of intracranial hemorrhage and was not caused by a broken femur, what kind of signs can be used?"

Gu Chen came with a question, and it was obvious that it was very targeted.

Forensic Doctor Liu smiled faintly and said, "The injuries caused by a fall from a staircase look like a fall from a building, or a car accident, or even a blunt force with a forceful and aggressive weapon. ”

"But our medical examiner examines the wound and can at least deduce what kind of weapon or object caused the wound. ”

Speaking of this, Forensic Doctor Liu raised his head and asked Gu Chen: "By the way, have you made a record of the situation of the stairs at the scene?"

"Yes. Officer Wang reacted slowly, but he quickly took out his mobile phone, clicked on the photo album and handed it to Forensic Doctor Liu: "This is the situation we filmed at the scene, and all the details of the corridor are here." ”

"Hmm. Forensic Doctor Liu nodded slightly, took the mobile phone and checked it carefully, and couldn't help but say:

"In general, fine thorns, paint or glossy lacquer peeling from stairs are found in the wounds of the deceased, or wall plaster and stucco debris are found. ”

"If the test results are household materials, we would guess that the wound may not have been caused by a lead pipe or a murder weapon such as a bat. ”

"However, this can only be known using chemical tests and microscopic analysis of the sample. ”

"But at the moment, it's unlikely. ”

Turning his head to look at Xiong Li's body on the testing table, Gu Chen also said: "If Xiong Li hits her head when she falls down the stairs, and the force of the impact is strong enough to cause bleeding and flow into the brain or surrounding parts, then in addition to bruising, there is also a possibility of forming a hematoma on the scalp." ”

"That's right. Forensic Doctor Liu seemed to find resonance, and the tone of his voice instantly increased by a few decibels:

"You're right, even a bloody laceration, but it doesn't have to happen, but based on what you've described, the chances are high. ”

Leaving the workbench, Forensic Doctor Liu led everyone to the testing table, uncovered the manipulation that should be at the mercy of Xiong Li, and said:

"When we forensically examine the body, if we find that the deceased has suffered severe brain injuries or is bleeding profusely, I may determine that the cause of death is blunt force trauma to the head. ”

Analysis of this wound profile may also suggest that the injury was caused by a fall down a staircase rather than a blunt injury from an object. ”

Speaking of this, Forensic Doctor Liu looked up at Gu Chen and asked, "Can you be sure that the corridor there is the first scene?"

The distribution of blood stains at the scene can show that Xiong Li did fall to her death from the corridor, and there were blood stains on the steps. Before Gu Chen could speak, Officer Wang interjected.

"Hmm. Hearing Officer Wang's remarks, Forensic Doctor Liu nodded slightly: "If this is the case, it is best, but if it can't be determined, we can also use the corpse spot pattern, which can also help to judge." ”

"Corpse spot pattern to determine the place of death?" Lu Weiwei was stunned, a little puzzled: "I know that corpse spots can determine the time of death, but you use it to determine the place of death, how do you say this?"

"It's not hard. Gu Chen glanced at Lu Weiwei, and also said for Forensic Doctor Liu: "Because the corpse spot is a blue-gray ecchymosis phenomenon in the low area of the corpse. ”

"If the body is in a supine position, the spots will emerge along the deceased's back. ”

"And the spots appear to dissolve in the first two or three hours or so, and fix after eight hours. ”

"But this process is quite time-consuming, and within two to eight hours, some of the corpse spots will be fixed in the lower area of the corpse's initial position. ”

"As the posture changes, corpse spots will also appear in the new low area. ”

Hearing Gu Chen's words, Gao Chuanfeng, who was standing on the side, was also a little impatient, and couldn't help but echo and said: "So if our forensic doctor finds a corpse spot on the deceased's back, but the body is lying prone downward, it means that the deceased has been moved six to eight hours after he lost his breath, or even longer. ”
