Mink Fang first began to examine the female corpse, and the most obvious fatal wound on the female corpse was the steel nail in the ear.

In order to observe the scars, Mink Fang directly performed a cranial opening on the corpse.

“…… The steel nail was pierced from the ear canal, the tube was 12 cm deep, penetrated the dura, arachnoid and temporal lobes, and eventually caused clinical death......"

"12 centimeters? So long? Yan Sixian said.

After the instrument scanned and drew a 3D image of the trauma, Mink Fang finally pulled out the steel nail in Zhang Wanqing's ear.

When—

The steel nail was thrown into the iron plate beside it, and it was seen that half of the nail had a screw buckle, and half was smooth.

"I have seen a lot of injuries caused by nails in the daily injury evaluation, but this is indeed the first time I have seen such a long nail." Mink Fang said.

"You're saying it's rare, and maybe even custom-made?" Yan Sixian took out his mobile phone, "I'll find someone who knows how to ask." ”

I don't know who he sent a message to, and soon the other party replied, and after reading the reply, Yan Sixian shook his head and said: "This thing is an ordinary Phillips carbon steel self-tapping screw, which is used less daily, because it is too long, generally an 8 cm one is enough, and a 12 cm one is usually used for hanging and fixing particularly heavy things."

Although it is less useful, it is far from the point where it needs to be specially made, and it can still be bought...... The question is, where did the murderer get the steel nails? It's outrageous to buy such a thing as a murder weapon...... It was taken from the scene, that is, from the nightclub, right? ”

Yan Sixian directly took a photo of the nail and sent it to Wu Duan, and indicated the size, asking him to ask the nightclub staff if he knew where there were such nails in the store.

After sending the message, seeing that Mink Fang was conducting other examinations on Zhang Wanqing's body, Yan Sixian helped her take pictures, and while she was busy, she looked at the male deceased on the corpse bed next to her.

"You just said that he could die of allergies?" Yan Sixian asked.

"Hmm."

"Now that I know the identity of the deceased, I will inform Xiaoxiao to call up the case to see if this Ma Duanqing has a history of allergies."

"Okay."

Mink Fang had to admit that cooperating with Yan Sixian would get twice the result with half the effort, and he could always think of the work two or three steps later in advance.

However, Yan Sixian sent a message to Feng Xiaoxiang, but she didn't get a response for a long time, and she never answered the phone.

It wasn't until half past four in the morning, when the autopsy was almost over, that Feng Xiaoxiang found the autopsy room.

She had two big dark circles under her eyes, Yan Sixian looked at her stunned for a moment, and asked, "How is the situation over there in the network supervisor?" ”

Feng Xiaoxiang shook her head, "It's not good, many onlookers in the nightclub have taken pictures, and there are videos, which have begun to spread virally, and if you want to delete them, it will take a few days, and Zhao Ju is still in the Internet Supervision Department just now." ”

There is only one reason why Feng Xiaoxiang can be late - the workload of the Network Supervision Department has exploded.

Yan Sixian thought that Zhao Ju, who was already in poor health, was called to preside over the work in the middle of the night, and suddenly felt that it was not easy to lead.

Feng Xiaoxiang said: "Ma Duanqing's allergy history has been found out, he is allergic to peanuts, and he has rescued ...... before."

"Peanuts! It's peanuts! Mink Fang was a little excited, "His throat and respiratory tract are constricted, as well as rashes and blisters, all of which are symptoms of peanut allergy!"

Although some special examinations are still needed for the final determination, from the perspective of symptoms, ninety percent can be sure that it is a peanut allergy! ”

No wonder Mink Fang was excited, she thought that the toxicology and pathological examination and analysis would take a few days to torture and kill a lot of brain cells, but she didn't expect the cause of death to be seen so soon.

Feng Xiaoxiang continued, "In addition, I also checked the resume information, bank accounts, call records, and social software chat records of the two deceased. It's all here......" She put a tablet on the table, and ran to the autopsy room as she said: "The Internet Supervision Department has blown up, I have to go back to help in the past two days, if there is any information that needs to be checked, send it to me directly, and I will help you check it when I have time." ”

As soon as she said this, Yan Sixian remembered that Feng Xiaoxiang's establishment was not in the criminal investigation team, but in the Internet Supervision Department, but she had been responsible for assisting the criminal investigation team in normal times, and everyone had already regarded her as a member of the team.

After Feng Xiaoxiang left, Yan Sixian picked up the tablet she left behind, looked down at the information on it, and the more he looked at him, the more frowning his brows became.

Mink Fang on the side said: "Hey, don't frown, it's not handsome." ”

Yan Sixian smiled and said distressedly: "I can't see any intersection between the two deceased, at least not at all from the existing information...... They died in the same place at almost the same time, it can't be just a coincidence, right? ”

Mink Fang sutured the anatomical wound on Ma Duanqing's chest and abdomen, and said, "I don't know if it's a coincidence, I only know that Zhang Wanqing most likely died of his murder."

Usually the blind tube puncture wounds left by the nails are caused by falls, falls, and the injured person is accidentally pierced by the nail when falling and falling, so that in addition to the blind tube puncture wounds, there will also be rubs and bumps, but Zhang Wanqing's body is very clean and there are no such injuries.

That nail...... It was as if someone had covered her head and stabbed her through the ear. ”

"By the way, that package of white powder," Yan Sixian said, "Could it be a drug?" ”

"No, the poison laboratory has just come out with the test results, and that is sleeping pill powder."

"Sleeping pills?"

"Well, just to be on the safe side, Zhang Wanqing's urine was just extracted for a drug reaction test, and she was negative for most of the common drugs on the market, and she doesn't take drugs."

A packet of sleeping pill powder, was this thing for her own use, or—to whom was it going to be used?

Yan Sixian's mobile phone rang, and it was Wu Duan calling.

"The nail has been found!" Wu Duan said: "According to a cleaning uncle, when he was cleaning today, he picked up a similar long steel nail in the corner of the bar, and he wanted to take the steel nail home in his pocket, but the pocket was broken, and the steel nail may have fallen in the men's toilet, because he entered the men's toilet many times to clean." ”

Yan Sixian asked, "Then when he went in and out of the men's toilet, did he find anything abnormal?" ”

"I'm asking all the nightclub staff who have been in and out of the men's restroom, and how many more guests there are...... It's difficult, there is a monitoring counter at the entrance of this store, and there is more than this entrance, and the situation inside is difficult to grasp. ”

"Is it surveillance?" Yan Sixian asked.

"After the test, even if the hope is slim, you always have to go through the sieve, now focus on checking"
