In the conference room of the Criminal Investigation Detachment of the Jing'an City Public Security Bureau, a case analysis meeting was held to summarize clues.

Mo Yufei stood in front and completely sorted out the identity information of the deceased.

"The deceased's name is He Yetong, Chinese New Year's Eve, a native of Jing'an City, divorced, and currently single. He is the owner of a textile company, with seven companies under his name, three real estates, and personal assets of more than 10 million.

According to the description of Wang Fanghua, the deceased left the company at 3 p.m., and according to the deceased, she was unwell and wanted to go back to rest. At half past four in the afternoon, the secretary Wang Fanghua called the deceased's phone several times, but did not answer. At five o'clock in the afternoon, Wang Fanghua came to the deceased's residence, opened the door with a key, and found that the deceased had been killed, and then called the police. ”

After Mo Yufei finished reporting, she cast her eyes at Lu Ke.

Lu Ke paused, fiddled with a gel pen in his hand, and asked, "Have you found out the emotional relationship of the deceased?" What about her ex-husband's situation? ”

Mo Yufei was stunned for a moment, then rummaged through the notepad in his hand, and then said: "The deceased's ex-husband is called Fan Chengji, who is also thirty-two years old this year. The two have been married for five years, have no children, and divorced two years ago. ”

After Mo Yufei finished speaking, she just sat down, stood up suddenly, and added: "According to the information, the deceased He Yetong's company was basically opened after the divorce, and the registered capital is quite a lot, it seems that the divorce should give her a lot of money." ”

Lu Ke nodded, still fiddling with the gel pen in his hand, his eyes swept over the people around the conference table, and asked, "Is there any information about the deceased?" ”

Su Simeng slowly got up and said at the right time: "I have investigated some things through the deceased's company, and I have not found any clues directly related to this case. The most recent company project was a bidding half a year ago, when the Municipal Planning Bureau began to develop a piece of land in the west of the city, and conducted a public project bidding, which was tendered by bosses from all walks of life in Jing'an City and neighboring provinces and cities, and finally, the deceased He Yetong successfully bid for the land and is currently working on the development. ”

He paused and put forward his opinion: "Half a year is a bit ambiguous for this case, and this case does not rule out retaliatory killings caused by commercial competition. ”

Lu Ke pondered for a while, and said lightly: "Investigate, participate in the bidding meeting, see if there are any companies that are hostile to the deceased or have direct competition, and look for clues." ”

Su Simeng replied and sat down.

The case analysis meeting fell into a short silence, and seeing that no one continued to speak, Ling Zizhen was about to start reporting on the situation of the on-site investigation.

He stood up and walked over to the Lord. Seat position, operating projection equipment.

The first sentence he opened his mouth denied and questioned Su Simeng's view of commercial competition and revenge homicide from the side: "According to the investigation of the crime scene, there are obvious signs of rummaging in the house, and the possibility of retaliatory homicide caused by commercial competition contradictions is unlikely, and it may be accompanied by burglary." ”

Subsequently, he pressed the remote control pen, and the on-site investigation photos were projected on the big screen.

"According to the investigation of the scene, there are no signs of damage to the doors and windows, and the murderer entered the scene through the gate, using the key to open the door and call the door to enter.

At the door of the deceased's bedroom, the technical team found a clear dust footprint, the footprint was thirty-six yards, judging from the texture of the sole, it should be a pair of sneakers. According to shoe size analysis and stride length reasoning, this person is a male with a height of about 1.6 meters.

In the bedroom of the deceased, there are traces of rummaging, although the situation of recovery after rummaging, it is still relatively obvious. There were large scratches on the side of the bed, and the deceased's bed had a large gap under the bed, so someone must have rummaged under the bed for something, and it was a large object.

It's just that the technical team didn't find any valuable fingerprints in the rummaging places, but found traces of nylon cotton threads, and this person should have been wearing labor protection gloves to rummage.

It is not known how the deceased's belongings were lost for the time being, but according to the description of the informant, the deceased would have kept some emergency cash at home, but the amount is unknown, and the technical team did not find the cash, so it is very likely that it has been lost.

Judging from the results of the scene investigation, it is likely that this is a crime of passion triggered by a burglary case. But judging from the chronological order, the possibility of an acquaintance committing the crime cannot be ruled out, because the murderer is likely to have the key. ”

After listening to Ling Zizhen's on-site investigation report, Lu Ke cast his gaze at Jiang Xiran and Zhou Xiaoyi again: "Are there any clues in the autopsy?" ”

Jiang Xiran sat on the chair, stretched out his hand to open the autopsy report, and then raised his head and motioned for Ling Zizhen to replace the photo on the big screen with a close-up photo of the corpse.

She put one arm on the table, glanced at the autopsy report, and said lightly: "There is only one wound on the body surface of the deceased, the wound is located in the back of the head, it is a blunt force blow, and there is no repeated blowing." The wound is V-shaped, most likely caused by blunt force such as metal forceps.

The autopsy found that the deceased's head trauma had resulted in a skull fracture and a mild head injury. If the murderer used the killing tool is pliers, then the murderer's strength should be great. However, this level of injury does not cause the deceased to die on the spot, at best it is a deep coma, but if it is not helped for a long time, it will die due to blood loss or brain injury.

Therefore, the real cause of death of the deceased is death by suffocation. The body was located in the center of the living room, and no traces of blood were found at the scene, indicating that the living room was the scene of the first crime, the corpse was intact, and the body had not been moved. There are no strangulation marks and strangulation marks on the neck, and there is no pressure on the body that affects breathing, and the deceased is likely to die of suffocation caused by someone covering his mouth and nose.

The time of death of the deceased was around five o'clock in the afternoon, measured by liver temperature. It is worth noting that the wound on the back of the deceased's head showed signs of contraction, and the life response was obvious. Therefore, the murderer should first hit the back of the head, causing the deceased to fall unconscious, and then covering the deceased's mouth and nose, causing him to suffocate to death.

Also, the deceased's clothes, though visibly wrinkled, were not sexual. In the case of the assault, no male DNA or biological information was found on the deceased's body. ”

After Jiang Xiran finished speaking, Zhou Xiaoyi got up again and added some clues: "The Technical Investigation Department cooperated with the investigation of the deceased's mobile phone, the deceased's mobile phone was not silent, and it did receive a call from Wang Fanghua. The mobile phone was found at the bedside of the deceased, and there is no possibility that the mobile phone ringing could not be heard, and the only explanation is that the deceased had lost the ability to answer the call when the call came in. ”

After listening to these clues, everyone present was a little puzzled.

Although the conclusions of the on-site trace examination and autopsy are correct, there are contradictions between the two, especially some discrepancies with the description of the applicant Wang Fanghua.

Moreover, the deceased's mobile phone is a new model that has just been put on the market, and it can be sold at a good price even if it is second-hand. If it is a burglary, it is impossible for the murderer not to be tempted by the deceased's mobile phone.

Mo Yufei was straightforward and straightforward, and directly raised a question: "The policeman said that she had made many calls to the deceased at half past four and no one answered. But the time of death was five o'clock, and what happened to the half hour in between? ”

Jiang Xiran glanced up at her and immediately added: "The liver temperature measurement is different from the gastric dissolution detection, there will be some errors in the time of death obtained through the detection of gastric dissolutes, and the death time obtained by the liver temperature measurement is very accurate." ”

Mo Yufei was a little embarrassed, and explained again and again: "Forensic Doctor Jiang, I didn't question the meaning of the time of death......

At this time, Lu Ke opened his mouth to relieve Mo Yufei: "This shows that the murderer hit the deceased with a blunt object before half past four, and then covered her to death at five o'clock." ”

What makes the police wonder now is what happened in the middle half hour......
