Chapter 595 Identity of the Corpse

Although the waxed corpse is disgusting, one thing that is very useful for solving crimes is that the corpse wax will retain traces of life on the surface of the corpse, such as bruises, strangulation marks, etc.

As for corpse spots or putrid veins, they will not appear on waxed corpses because the corpse is not putrefied. Corpse spots and putrid veins are the characteristics of putrified corpses.

Lifting the white cloth covering the body, Chen Yan carefully examined the appearance of the body.

First of all, there are no obvious traumatic injuries on the surface of the corpse, which means that the deceased did not die from trauma. Due to the low fat content, there is no obvious corpse waxing phenomenon on the neck, but it is still in the process of corpse waxing, and there are obvious strangulation marks. , in the shape of a tiger's mouth.

The deceased should have been strangled by the murderer before his death. As for whether it was the cause of death, follow-up examinations will be conducted.

When the deceased was found, he was not wearing any clothes and no identification documents were found.

There were no obvious scars on the torso, and there were obvious stretch marks on the abdomen. When Chen looked down and raised the deceased's wrist, there were obvious strangulation marks. The deceased should have been restrained by ropes before his death. There were no scars on the legs, but there were strangulation marks on the ankles.

Wu Zhiguo followed Chen Yan: "The preliminary inspection results of the on-site investigation investigators believe that the cause of death was suffocation. The deceased had been restrained before his death, and there were obvious strangulation marks on his wrists and ankles."

"The identity of the deceased has not yet been determined. We have collected facial features and tissue samples to extract DNA information for comparison."

Chen Yan nodded: "During the autopsy, pay attention to the middle finger and ring finger of the deceased's right hand. When I was inspecting just now, I found that there may be some tissue components in the nails of the middle finger and ring finger of the deceased's right hand, and there may be some clues."

"yes!"

The situation at the scene is relatively simple. This is not the scene of the first crime. The murderer just dumped his body here.

And because the murderer dumped the body for a long time, it has been at least three or four months since the traces at the scene have long since disappeared, and no clues have been found in trace investigation.

"Where is the reporter?"

Wu Zhiguo pointed to the two people standing in the distance: "The two maintenance workers squatting over there are the people who reported the crime."

Chen Yan walked up to the two of them and the detective responsible for recording the confession stepped aside. Even though nearly an hour had passed, Lin Sheng and Zhao Ye didn't seem to have recovered, and their whole bodies were trembling unconsciously.

"Lin Sheng, my name is Chen Yan and I am the deputy captain of the Liancheng Detective Team. Don't be nervous."

Lin Sheng looked at Chen Yan: "Chen... Hello, Captain Chen."

Looking at Lin Sheng who was still trembling, Chen Yan also understood that whoever saw a waxed corpse in the water tank would not be any better than Lin Sheng.

"Lin Sheng, is the isolation door on this rooftop usually closed or open?"

"Yes...it's open. The rooftop is an emergency refuge and the door cannot be locked."

turned on...

"In other words, anyone in this building can come up to the rooftop?"

Lin Sheng nodded: "Yes."

"Who has the key to the water tank's lock?"

"There is a water storage tank on the roof of every high-rise building in the community. The lock is customized and can be opened with the same key. The key is at the property. Anyone who needs to use it can go to the property office to get it."

"Is the water tank up here maintained?"

"We come here to inspect it twice a year. The last inspection of this water storage tank was in May. It was inspected by Zhao Ye and I. At that time, we made sure that the lock was in good condition."

"Captain Chen, Brother Lin is right. The lock must have been in good condition at that time, otherwise we would have replaced it."

The two of them didn't know much.

Chen Yan did not obtain any more information, but judging from the inspection time, it can initially narrow down the time frame when the murderer dumped the body.

After May, and based on the time it takes for the body to wax, it will take at least three months, so the murderer committed the crime between May and June.

The on-site investigation work was quickly completed, and the body had been carried to the fourth team for autopsy.

A case analysis meeting was being held in the conference room of the fourth team. In addition to Chen Yan and Wu Zhiguo, members of the serious crime team such as Liu Qingshan, Zhang Chaoyang, Wang Gang and Zhao Bing were also present.

The basic situation of the case has been reported to the Detective Team of the Liao Provincial Detective Brigade, and the case is now taken over by the Serious Crime Team.

At the meeting, Chen Yan directly deployed work tasks.

"The first is to determine the identity of the deceased. We did not find any documents at the scene that could prove the identity of the deceased. However, because the body of the deceased was paraffinized, the face was clear and DNA information could be extracted, Captain Liu."

Chen Yan looked at Liu Qingshan: "You are responsible for verifying the identity of the deceased."

Liu Qingshan nodded: "Yes."

"Second, conduct a comprehensive survey in the community, especially the residents of Building 3. According to the information provided by the informants Lin Sheng and Zhao Ye, they conducted a survey on the water storage in Building 3 on May 18 this year. Tank inspection."

"They determined that the lock of the water tank was not damaged at that time, which means that the murderer had not committed the crime before May 18."

"Based on the waxing condition of the corpse, the paraffinization time should be at least three months, which means the corpse was thrown into the water storage tank before June 20."

"So, we can probably locate the murderer's time period between May 18 and June 20."

Chen Yan looked at Wu Zhiguo: "Captain Wu, Shanhe Jiayuan Community is your jurisdiction. You are more familiar with the situation in the community. It is up to you to send people to promote this work."

"The key point is to check whether there are any missing persons in the community during this time period, and whether the residents in Building 3 found any abnormalities during that time period."

There are three units in Building 3. The elevator in any unit building can go directly to the top floor and then onto the rooftop, so the residents of these three units must be checked.

"Third, we need to determine the cause of death of the deceased as soon as possible, and the tissue material that may remain in the nails of the deceased's right hand must be analyzed as soon as possible. This is very likely to point us directly to the murderer."

"Captain Wu, your team will be responsible for the autopsy. Please give instructions."

"Don't worry, Captain Chen, I will keep an eye on it personally."

"Okay, the meeting is over, let's all split up."

One of the more difficult aspects of the case is that there is no way to obtain surveillance.

The monitoring system of Shanhe Jiayuan Community is relatively complete. Chen Yan had already noticed it when he entered the community. There are surveillance systems at the entrance of each building and in the elevator in the public area of ​​the community.

The problem is that the monitoring of the community is covered cyclically. The video recording in the public area is covered cyclically every month. The monitoring video coverage in the elevator is even shorter, only 7 days.

The deceased's death was at least three months ago, so there must be no clues in the surveillance data.

Therefore, the most important thing now is to determine the identity of the deceased, and then use the deceased's relationship network to identify the suspect.

Otherwise, the body was dumped so long ago that no clues remain, and there is no clue at the first crime scene.

All the surveillance videos in the community have been covered. If the identity of the deceased cannot be determined, the investigation of the entire case will reach a deadlock.

Fortunately, there is always a road ahead. To Chen Yan's surprise, Liu Qingshan got the results in less than two hours.

"Team Chen, the deceased's identity information was compared in the missing persons information database."
