The latest website: Waxed corpses are disgusting, but they are very useful for solving crimes, that is, wax will retain traces on the surface of the corpse, such as bruises, strangle marks, etc.

As for the corpse spots or rotten venous network, they will not appear on the waxed corpse, because the corpse is not corrupted, and the cadaveric plaques and rotten venous network are the characteristics of the rotten corpse.

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

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

The deceased should have been strangled by the murderer before his death, and follow-up examinations should be carried out as to whether it was the cause of death.

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

There were no obvious scars on the torso, and there were relatively obvious stretch marks on the abdomen. Looking down, Chen Yan lifted up the wrist of the deceased, and there were obvious strangle marks. The deceased should have been bound by ropes before his death. There were no scars on the legs, and there were strangle marks on the ankles.

Wu Zhiguo followed Chen Yan: "The preliminary inspection results of the on-site investigation and detectives concluded that the cause of death was suffocation. The deceased had been restrained during his lifetime, and there were obvious strangle 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, I looked at the **** and ring finger of the deceased's right hand. When I was checking just now, I found that there may be some tissue components in the nails of the **** and ring finger of the deceased's right hand. Maybe there are some clues."

"Yes!"

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

And because the murderer had thrown the body for a long time, at least three or four months so far, the traces of the scene have long since disappeared, and no clues have been found in the trace investigation.

"Where is the informant?"

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

Chen Yan walked up to the two of them, and the detective who was in charge of recording the statement stepped aside. Even though nearly an hour had passed, Lin Sheng and Zhao Ye seemed to have not recovered, and their whole bodies were trembling unconsciously.

"Lin Sheng, my name is Chen Yan and I'm the deputy captain of the Liancheng detective team. Don't be nervous."

Lin Sheng looked at Chen Yan: "Hi Captain Chen Chen."

Looking at Lin Sheng who was still trembling, Chen Yan also understood that no one who saw a waxed corpse in the water storage tank would be better than Lin Sheng.

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

"It is open, the roof is an emergency shelter, and the door cannot be locked.

open

"That is, anyone in this building can come on the roof?"

Lin Sheng nodded: "Yes."

"Who has the key to the lock of the water tank?"

"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 storage tank up here maintained?"

"We come up to check twice a year. The last time this water storage tank was checked was in May. It was checked by me and Zhao Ye. At that time, we confirmed that the lock was intact."

"Captain Chen, brother Lin is right, the lock must have been intact at that time, otherwise we would have replaced it."

The two don't know much about it.

Chen Yan didn't get more information, but judging from the inspection time, it can be initially narrowed down the time frame for the murderer to dump the body.

After May, and according to the waxing time of the corpse, it will take at least three months, so the time for the murderer to commit the crime is from May to June.

The investigation work on the scene ended soon, and the body has been carried to the fourth team for autopsy.

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

The basic situation of the case has been reported to the detective team of the Liao Provincial Criminal Police Brigade, and the case is now being 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, but the corpse of the deceased has a clear face due to paraffinization, and DNA information can also be extracted, Team Liu."

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

Liu Qingshan nodded: "Yes."

"Second, carry out a comprehensive survey in the community, especially the residents of Building No. 3. According to the information provided by the informants Lin Sheng and Zhao Ye, they conducted a survey on the water storage of Building No. 3 on May 18 this year. Inspections conducted by tanks."

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

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

"So, we can probably pinpoint the time period when the murderer committed the crime between May 18 and June 20."

Chen Yan looked at Wu Zhiguo: "Captain Wu, the Shanhejiayuan community is under your jurisdiction. You are more familiar with the situation in the community. You will send people to advance the work in this area."

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

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

"Third, the cause of death of the deceased must be determined as soon as possible, as well as the tissue material that may remain in the nail of the deceased's right hand. It is necessary to analyze it as soon as possible. This is very likely to point us directly to the murderer."

"Captain Wu, your team is in charge of the autopsy, so please tell me."

"Team Chen, don't worry, I will keep an eye on it myself."

"Okay, the meeting is over, everyone split up."

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

The monitoring system of Shanhejiayuan community is relatively complete. Chen Yan had already noticed it when he entered the community. There are surveillance cameras in the public area of ​​the community, as well as at the entrances of each building and in the elevators. UU reading

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

And the time of death of the deceased was at least three months ago, there must be no way to find clues in the monitoring data.

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

Otherwise, the body throwing scene has been going on for a long time, and there are no clues left, and there is no clue at the scene of the first crime.

The surveillance video in the community has also been fully covered. If the identity of the deceased cannot be determined, the investigation of the entire case will be deadlocked.

Fortunately, there is no unparalleled road, and to Chen Yan's surprise, Liu Qingshan had the result in less than two hours.

"Captain Chen, the identity information of the deceased has been compared with the missing persons database."
