Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

While Lu Chuan was doing the identification and analysis of the scene, the forensic doctor also performed an autopsy on the corpse.

There is not much difference from Lu Chuan’s conclusion at the scene. The deceased’s fatal injury was the scar on the neck. The rupture of the carotid artery caused a large amount of blood loss and eventually led to death from shock.

The carotid arteries are located on both sides of the throat and are the two most easily felt arteries in the human body.

By placing your palms on both sides of your throat, you can clearly feel the beating of your carotid arteries.

It is very different from bleeding after a vein injury. After an artery is injured, the blood bleeds in a gushing manner rather than a flowing manner.

After the carotid artery is injured, blood can spray up to three meters away.

However, after the carotid artery is injured, it will not cause the victim to die immediately. The blood loss process will last about 3 to 15 minutes.

During this process, the victim is still conscious and will experience different symptoms such as weakness, fatigue, chills, dizziness, etc.

Compared with arteries in other parts of the world, injuries to the carotid artery are more difficult to deal with, and the possibility of fatal injuries is greater.

Especially when both carotid arteries are injured, this change is almost irreversible.

If other arteries are injured, it may be possible to stop arterial bleeding by squeezing the blood vessels with huge pressure.

However, after the carotid artery is injured, using this method will undoubtedly accelerate the victim's death.

Because the carotid artery supplies blood to the brain, once the carotid artery is compressed and unable to pass blood, the brain will soon die due to lack of oxygen.

One of the victim's two carotid arteries was completely severed, and 2/3 of the other was severed.

The middle part of the throat has been completely cut open, with only a thin thread still connected.

From a forensic perspective, it can be judged that the murderer was precise and ruthless when he struck.

The angle was tricky and the force was enormous, and the blow cut off the throat.

The judgment of the time of death was also consistent with Lu Chuan's, it was 1:30 in the morning yesterday.

While the investigators and forensic scientists were busy working, the crime team and the BZ City Criminal Investigation Detachment were also busy.

The identity of the deceased has been clarified. Zhao Kai, male, 38 years old, ran a building materials business in the Northern Market.

The person who called the police was his wife Li Guifen.

"Li Guifen and Zhao Kai got married before the Chinese New Year in February this year. They were both married for the second time."

During the day, Gao Xiang had arranged for someone to investigate the family situation of the deceased.

"We contacted Li Guifen's unit as soon as possible and confirmed that Li Guifen was on duty on the railway section from 22: a.m. the day before the incident, that is, on the nd, to : a.m. on the morning of the incident."

"The time of death of the deceased was 23:1 in the morning on the 30rd, so it is confirmed that Li Guifen had no time to commit the crime."

While Li Donglin was listening to the report, the pen in his hand kept recording something in the notebook.

Gao Xiang continued to report: "And judging from the method of killing the victim at the scene and the steel nails on the top of his head, the murderer is the murderer of three serial murders since March 3."

Although three serial killings occurred, the police did not disclose the relevant details.

How did the murderer kill? What weapon was used to kill the person, as well as the steel nails on the head, etc., these details have not been disclosed to the public.

If someone imitates the case, the possibility is basically non-existent.

This judgment is also recognized by the crime squad.

"Is there any connection between this Zhao Kai and the three people in front of him?"

Gao Xiang shook his head: "We have checked the call records between the first three victims and Zhao Kai during the day, including bank transfer records, but nothing was found." "Where is the chat software?"

"No, I've checked and found that these people probably don't know each other."

The relationship between the three people after the first three cases was also the focus of Gao Xiang's investigation, but a week passed without much progress.

Li Donglin thought for a while and looked at Wang Song: "How are you doing here?"

This morning Lu Chuan and others were conducting surveys at the site. Wang Song, Song Mingguang, Luo Qiang and others immediately launched an investigation.

Wang Song straightened his back: "Let me talk first."

"After asking the caller Li Guifen about the situation this morning, I got to know the general situation of the community and did some visits and investigations."

"As the Gao detachment just said, Li Guifen's suspicion of committing the crime can basically be ruled out."

"Both of them are getting married for the second time. They were introduced to each other last year. Before the Chinese New Year this year, on February 2st, they received their marriage certificate and held a wedding."

"The wedding was not a big deal, and the people attending were just two friends who were familiar with each other."

"Two people have a prenuptial agreement before marriage, and their respective properties and finances belong to each other."

"After getting married, the two of them spent 2000 yuan a month on the family's public expenses."

"After investigating the circumstances of these two people's first marriages, they divorced three years ago and two years ago respectively."

"Li Guifen has a fourteen-year-old son who lives with her ex-husband."

"Zhao Kai has a special situation here. He was divorced two years ago. The child was twelve years old and was awarded to him at the time. However, he left the child with his parents in his hometown and never took it with him."

“After some investigation, I found that their ex-wives and ex-husbands are currently not in BZ City.

One is in Tianzhou and the other is in Haizhou, and there is no recent contact between them in the call records and chat records. "

Wang Song's investigation here is obviously much more detailed.

"Regardless of the murderer's method of killing or whether he is the murderer of a serial murder case, in this kind of complex family situation, I think it is necessary to exclude family members from committing the crime as soon as possible."

Wang Song had just entered the investigation, so he did not fall into the fixed mindset of serial murders like Gao Xiang and others.

"I checked the bank statements of the two people and found nothing unusual. The ex-husband and ex-wife of both parties have normal monthly alimony payment records."

"From these aspects, the possibility that Zhao Kai was killed due to family reasons is not high."

Wang Song looked at Gao Xiang: "So there is basically no problem in the judgment made by Gao Detachment and others that the murderer is a serial murderer."

Some people from the BZ City Criminal Investigation Detachment were not convinced and looked at Wang Song secretly.

Of course there is no problem. With such an obvious killing method, how could it not be the same person?

Wang Song didn't care and continued: "So, why did the murderer kill four unrelated people?"

Wang Song's eyes were bright.

"We have also initially considered that there should be some kind of connection between the victims."

Gao Xiang also had a headache.

Wang Song's thoughts or questions were what they wanted to find out, but the problem was that no useful clues had been found this week. (End of chapter)
