Chapter 448 Confirming the Identity of the Deceased (Two-in-One Vote Request!)

Chen Yan, standing next to the trunk of the car, had a livid face.

The left arm in the No. 3 black plastic bag was actually frozen.

And the skin color and size were obviously different from the right arm.

This means that there were at least two victims!

Moreover, there were also crisscrossing scars on this left arm.

Because the arm had been frozen, the injuries were kept very intact, and it was still possible to tell which were pre-mortem injuries and which were fatal injuries.

Putting down the arm in the No. 3 plastic bag, Chen Yan opened the last plastic bag.

This contained the torso.

Judging from the skin color and the scars on the broken right arm, this torso should belong to the same victim as the right arm.

There were scratches on the surface of the torso, burns, and traces of animal gnawing.

Hmm?

After taking out the torso, Chen Yan found an obvious plum blossom-shaped burn at the navel.

It was different from the other burns on the torso and arm.

The burns Chen Yan just found were similar to those caused by cigarette butts.

However, this plum blossom-shaped burn mark is very obvious, and it should be caused by something like a branding iron.

Liu Qingshan also discovered this burn.

The wound is very obvious. Since the deceased died recently, the burn is like a branding.

The skin has melted and charred, revealing the underlying muscle layer.

It exudes a strange fragrance.

Generally speaking, murderers rarely leave unique marks on the body.

If there is, it must represent some meaning.

"Is it some kind of ritual, or the killer's own mark?"

Chen Yan shook his head: "It's not certain yet."

However, whether it is a sense of ritual or the killer's self-marking, it can show that the killer has a certain obsessive-compulsive disorder.

Chen Yan observed this wound very carefully.

The location of the burn is in the middle of the abdomen, just above the navel, and the distance to the left and right sides is symmetrical.

This kind of spatial symmetry is probably not a coincidence, because the murderer should have carefully considered it before doing it.

Gently turn the torso over, there are corpse spots on the back, and the color fades when gently pressed.

This means that the deceased should have been lying on his back for a long time after being killed, which would cause this kind of corpse spots.

"Take the body back to the autopsy room for autopsy, extract DNA information, and compare it with the missing persons database."

"Also, check the missing persons reported recently in Liao Province to see if there are any findings."

"Also, Captain Liu, send someone to retrieve all the surveillance videos near Linjiang Road."

"See if you can find the trace of the driver of the car and the driver of the off-road vehicle. Where did they go? Find them as soon as possible."

"Also, arrange personnel to check the trajectory of this car through the Sky Eye system."

"Although there is no important information left in this car, it is impossible for it to appear out of thin air after all."

"Okay, I'll arrange it now!"

"I just found a dry branch and two dead leaves in the trunk. Check to see where there are such trees near Liancheng."

[Ding! The strongest police training system task is released. ]

[Solve the serial dismemberment case, the deadline is five days. Complete the task and reward the skill of hearing enhancement. Failure or overdue cancellation of the task reward. ]

Hearing enhancement?

Chen Yan was slightly stunned.

This skill is good. Hearing enhancement should play a big role in the direct reconnaissance mission.

For example, when investigating the serial disappearance case in Kun City and investigating the imprisonment of Li Wenlong in the factory area, if there is hearing enhancement, Chen Yan's actions will definitely be much smoother.

However, I don't know to what extent this enhancement can be achieved.

Recently, with the increase in the number of cases I have handled, the rewards of the system seem to be slowly becoming a little weaker.

At the beginning, although the case was relatively small, the rewards of the system were very generous.

The olfactory gene lock and the visual gene lock helped Chen Yan to play a big role in handling the case.

But now, the system feels to Chen Yan as if it is running out of stamina.

It's like running out of energy.

Otherwise, this hearing enhancement should be replaced by turning on the hearing gene lock.

Shaking his head, Chen Yan no longer thought about the system.

The time travel has fallen on him, and it's not a big problem that the system is a little repetitive.

Leaving the scene, Chen Yan returned to the Liancheng Detective Team.

Zhang Yunhu's office.

"At present, there are at least two victims involved in this case."

The reason why Chen Yan said at least two people is because the left arm found in the trunk showed signs of being frozen.

Although it is not possible to determine the freezing time for the time being, it is obviously longer than the time when the victim with the head found in the trash can was killed.

So before the victim with the frozen left arm was killed, were there other victims?

No one can be sure.

"Has the provincial team reported it?"

Chen Yan nodded: "I have already told Li Hong, and he will report it to Team Qin."

"The case is still led by me."

"Okay, if there is any support, please arrange it at any time."

Chen Yan nodded and left Zhang Yunhu's office.

Now, the most important thing is to confirm the identity of the deceased.

This time, Chen Yan didn't have to wait for long.

Five hours after the scene inspection, Liu Qingshan and Zhang Chaoyang brought back good news.

The meeting room of the Liancheng Detective Team.

The first case analysis meeting of the dismemberment case is being held.

Zhang Chaoyang reported the situation first.

"The head we found in the self-built housing area has been identified."

The projection shows a photo of a woman.

"We checked the missing persons reported by various cities in Liaoning Province. There are four missing persons recently, two men and two women."

"Since the head found in the trash can was not damaged and the appearance was clear, after comparing the photos, it was found that it belonged to one of the missing persons."

"Jiang Zhu, female, 26 years old, a nurse at Qingsong Medical Beauty Hospital in Liancheng City, was reported missing three days ago."

"We used the Sky Eye system to investigate Jiang Zhu's movements on the night of September 6 when she disappeared."

The projection screen changes, showing photos taken by the Sky Eye system.

"At 8:03 p.m. on September 6, Jiang Zhu came out of the main gate of Qingsong Medical Beauty Hospital."

"Took a taxi on Zhengyang Road at the entrance of the hospital."

"At 8:34, the taxi stopped at the entrance of the alley in the self-built housing area where we found the head."

"Afterwards, Jiang Zhu got off the car and returned to her rental house in the alley."

The projection shows the last photo of Jiang Zhu appearing in the Sky Eye system.

Wearing a white dress, she got off the taxi at the entrance of the alley and entered the alley.

"The next day, September 7, Jiang Zhu was supposed to go to work at 10 a.m., but she never went."

"Her colleague called, but the phone was turned off. After a day, she still couldn't get in touch, so she reported her missing to the police."

"Any other information?"

"That's all for now."

Chen Yan nodded and looked at the last photo of Jiang Zhu before she disappeared on the projection screen.

"Does Jiang Zhu live at the entrance of the alley where we found the head?"

Zhang Chaoyang nodded affirmatively: "We have found the landlord and verified the specific situation."

"And we searched the house where Jiang Zhu rented."

"No abnormalities were found."

"This is a photo of the scene."

On the projection, photos of Jiang Zhu's rented room were played.

The area is not large, with only one bedroom and one living room.

But it is tidy and clean, and the quilts in the bedroom are neatly stacked.

"Did you check the video on the morning of September 7?"

"We did," Zhang Chaoyang nodded: "We not only checked the video on the morning of the 7th, but also the previous videos."

"Jiang Zhu's life is relatively regular. She goes out at 9 o'clock every morning. In the past, she could be seen on the surveillance camera walking out of the alley, but she was not found on the morning of the 7th."

"In other words, the time period when Jiang Zhu disappeared can be confirmed to be 8:34 pm on September 6th, after getting off the taxi?"

Zhang Chaoyang nodded: "The alley where Jiang Zhu lives has cameras on only one side, but not on the other side."

"But judging from Jiang Zhu's previous habits, she always took a taxi to and from work on the side with cameras."

"So, it is unlikely that Jiang Zhu left the alley from the side without cameras on September 7th."

"Did the person who dumped the head in the trash can find anything?"

If the other party dumped the body in the trash can, he would definitely appear in the alley in person.

If it can be captured on video, it will be very helpful to solve the case.

However, Zhang Chaoyang's answer disappointed Chen Yan.

"No."

"Because the trash can is located in the middle of the alley, it is not directly within the camera's range."

"Besides, there are many tenants in this alley, and the flow of people is very large."

"Every household may throw away garbage in the morning, so no one pays attention to who throws the black plastic bag."

"Besides, there is no surveillance at the other end of the alley, so there is no way to lock the suspect range."

"Have the neighbors of Jiang Zhu's rented house been checked?"

"This work is in progress, and there is no feedback yet."

Chen Yan nodded and looked at Liu Qingshan: "Captain Liu, what are the results of your investigation?"

"The autopsy report is out."

Liu Qingshan looked at the detective next to him, who was the detective in charge of the autopsy in the first team.

"Captain Chen, this autopsy was jointly conducted by our first and second teams."

"First, through DNA information comparison, it can be confirmed that the head found in the trash can and the torso, lower limbs and right arm found in the car belong to the same person."

"But the left arm is not Jiang Zhu's left arm."

On the projector, there is a body that has been pieced together.

"The specific time of death of the deceased should be around 10 o'clock last night."

"The cause of death is excessive blood loss."

The projector shows the specific autopsy report.

"According to the analysis of the scars on the body, the deceased should have been abused on the day of his disappearance, that is, September 6."

"The deceased has lacerations on his lower body, but we did not detect semen stains."

"It is preliminarily judged that the deceased may have been sexually assaulted, but the other party took protective measures and did not leave direct evidence."

"Are there any fingerprints on the body?"

"No, the murderer should have worn gloves during the violence and did not leave fingerprints."

"But we have some other discoveries."

The photo on the projector switches to an enlarged wound on the torso.

"There is a Y-shaped scar on the front of the deceased's torso, which extends diagonally from the clavicle on both sides to the sternum and extends to the abdomen."

"According to the analysis of the characteristics of the wound, the murderer used a scalpel and took an anatomical position to divide the body after the death of the deceased."

The projection switched again to the right arm: "There is also a break in the right arm. The opponent should have used a medical hacksaw, not an ordinary saw."

"But the technique is very rough. During the process of sawing off the bones, the saw blade sometimes breaks. Look here."

There is an obvious trace of dislocation at the broken bone residue.

"So, we initially determined that the other party had some medical knowledge, but not much experience."

"In addition, we found a small piece of skin debris in the deceased's right arm."

"But because it is so tiny, no DAN information has been extracted yet."

This is common sense.

Not all human tissues can extract DNA information.

Generally speaking, it is more convenient to extract it from dander.

However, this requires sufficient quantity.

The extraction of DNA information is not what ordinary people imagine. Putting tissue into some machine can automatically extract it.

The extraction of DNA information is very complicated and requires not only specialized analytical instruments but also many pharmaceutical aids.

Many test materials need to be soaked in medicinal water before genetic material can be extracted.

In this process, there is a loss of inspection materials.

Especially for hair and skin debris found at crime scenes, not every tissue found can detect DAN information.

Even if it can be detected, it will most likely be detected once.

Therefore, the success rate of detection is very high.

Because you only have one chance, if you waste it, it's over.

When investigating a murder case, any wasted opportunity may lead to insufficient evidence.

Sometimes, suspects have even been caught, but there is no evidence to convict.

"Any other discoveries?"

"Yes," Liu Qingshan stood up: "The DNA information of the left arm that we found in the trunk of the car that does not belong to Jiang Zhu has been extracted."

"And in the missing persons database, we matched the information related to missing persons."

The projection switches, and it's also a girl in a white dress.

"This girl's name is Su Yu. She is 24 years old and is from Tie City. She disappeared in Shen City two months ago on May 3."

Shen Shi is missing?

The arm actually appeared in Liancheng!

The scope of this murderer's crimes was not limited to Xia Liancheng.

"Is the dress in this photo what Su Yu was wearing when she disappeared?"

Liu Qingshan nodded: "Yes, when Su Yu disappeared, she was wearing the same white dress."

"This photo is the last photo found in the Sky Eye system after Su Yu disappeared."

this……

Su Yu was wearing a white dress when she disappeared, and Jiang Zhu was also wearing a white dress when she disappeared!

Is it a coincidence?

Chen Yan's face suddenly looked a little ugly.

If it's a coincidence, that's fine.

But if it’s not a coincidence, then the murderer most likely specifically picked the woman in the white dress to target!

Liu Qingshan naturally knew why Chen Yan's face suddenly became very ugly.

When he discovered this, Liu Qingshan had the same concerns as Chen Yan.

Therefore, he investigated the disappearance cases that occurred in Liao Province in recent years.

On the projection, two other photos appeared: "I have investigated the missing women cases in Liao Province in the past five years."

"Last year and the year before that, there were two missing cases of women in white dresses."

There are two more cases?

Of course, Chen Yan and Liu Qingshan are just guessing now, and they cannot be sure that the disappearance of the woman in the white dress last year and the year before last was related to this murderer.

"How was the video investigation on Linjiang Road?"

Regardless of whether it was a murderer or not, as long as the person is caught, it will eventually be figured out!

Putting aside his worries, Chen Yan asked about the work he had arranged at the scene.

"I have a clue."

What appeared on the projection was a slightly blurry photo.

"Linjiang Road is a dead end road that was only built last year. The video equipment was installed only last month and has not been commissioned yet."

"However, we checked the driving path of the black car."

"By checking the engine frame number, we confirmed that this car was a stolen car two months ago."

"The vehicle was originally white but was later repainted and changed to black."

"The license plate is also a fake one. It was on the road for the first time two months ago in Xishan Nursery Park."

Xishan Nursery Park is the largest nursery breeding base in Liancheng.

It's about fifty kilometers away from the city.

"This car seldom moves during the day and is usually driven out at night."

"Last night, this car appeared at the intersection of Huanghe Road and Jianshe Road."

"This photo was taken by the speed camera at that time."

Huanghe Road and Jianshe Road?

"Near the self-built housing area where Jiang Zhu's head was found?"

Liu Qingshan nodded: "This car was driving on Huanghe Road from north to south at 5:28 this morning. At the intersection of Huanghe Road and Jianshe Road, 300 meters ahead is the self-built housing area."

"So, it is very likely that the other party entered the self-built housing area from the side of Huanghe Road during this time period and abandoned the head."

"And the entrance to the alley near Huanghe Road is the end without camera surveillance."

The photo on the projection was changed to another one: "This is a photo of a car appearing at the intersection of Tianshun Road and Linjiang Road at 5:56."

"After that, the car should have entered Linjiang Road, and then a car accident occurred."

The driver of the car on the projection wore a mask and a cap, and even his hands holding the steering wheel were gloved.

"Is there a clearer photo that can show the driver's appearance?"

Liu Qingshan shook his head: "The other party is very cautious. In all the videos we investigated, the driver of the car has always worn a mask and a cap, and has always worn gloves on his hands."

Mask, cap, and even gloves on both hands while driving.

The murderer is not ordinary cautious.

But there is a problem here.

That is, why did he drive back to Jiang Zhu's residence and dump the head?
