Crime Profiler 2

Chapter 7
"From several relatively complete corpses, we found that the injuries have the same characteristics." Qin Ling brought up the photos taken during the autopsy, "Except for the parts cut off by the suspect, the injuries of these corpses are all Light on the outside and heavy on the inside, the body surface only has the characteristics of abrasions and subcutaneous bleeding, but there are serious injuries inside, such as comminuted skull fractures, skull base fractures, visceral ruptures, and long bone fractures. A situation of repeated impacts in a confined space."

"Gao Chui died?" Chen Detachment Captain asked.

"Yes." Qin Ling nodded, "The examination conditions of those dead bodies that have become boneless are not as good as these few, but the scars left on the bones are also consistent with the characteristics of death from a high fall, and the blood on the broken ends of the bones can prove that they were falling They were alive before falling into the elevator shaft, and it is very likely that they still have vital signs for a long time after falling into the elevator shaft."

"In addition, we also found some strange things." Qin Ling called up a few photos again, which were the remains of a pile of incinerated objects, "This was found in the elevator shaft, and colleagues from the laboratory department were testing the ingredients. The suspect is obviously not for the purpose of burning the body, this thing may help us find the suspect."

"And this." She called up a few photos again, which were the photos of the latest victim's feet. "The degree of ulceration of these victims' feet is obviously different from the degree of decay of the corpse. I haven't figured out the reason yet. Afterwards, I will conduct a re-examination of these corpses."

"Then, how do we do the next work?" Detachment Captain Chen asked.This project meeting did not give him any important tips, which made him a little confused about the next work.

"Next, continue to investigate according to the existing clues. Qin Ling will find out the suspicious points as soon as possible, and assist the police in City C to find the source of the corpse. This will be of great help in pinpointing the suspect." Tang Hegong thought for a while and said, "Zheng Yan, do you have anything to add?"

"First, the suspect should be over 60 years old." Zheng Yan said, "The suspect likes to wear yellow rubber shoes, which are also called Jiefang shoes. People used to wear them. They are cheap and convenient for doing farm work. But it is not suitable for the case, and no one wears it now. The suspect should wear this kind of shoes because of his habit. Those who have this habit are all old, at least 60 years old. I think the characteristics of the suspect’s footprints at the scene It can also prove this point." He glanced at Mu Xue, saw her nod, and continued, "In this way, the suspect either has limited living conditions, or has been in the countryside in his early years and has retained this habit. In addition , I said that this kind of shoes is hardly worn by anyone in the city now, and it is not easy to buy, and it may be a breakthrough in our investigation."

"Secondly, I'm thinking about maggots." Zheng Yan flicked through the photos in his hand, "There is no doubt that the suspect is cultivating maggots, but what is his purpose of cultivating maggots? The larvae of mung bean flies like viscera and are sensitive to decay. The meat is very sensitive and not suitable for consumption. Finding the purpose of the suspect is crucial to narrowing the scope of the suspect."

"This is the main point of doubt." In the forensic autopsy room of the funeral home in C City, Qin Ling pointed to a relatively complete corpse on the dissection table and said, "The ulcer on the victim's foot is obviously abnormal. Look at the skin on the ulcer." She used The tweezers carefully picked up the skin tissue, and said: "The color of the skin is cyanotic, which is not the color of normal corruption. There is also a clear difference between the degree of corruption and the degree of corruption of the whole body. You may not believe it. Judging from the condition of the wound, this place should be the most Where the corruption happened first, but to a lesser degree."

"Look here again." She enlarged the area of ​​the wound, exposing the honeycomb tissue under the skin, and the densely packed holes under the feet made everyone involved in the autopsy feel scalp numbness, "Normal decay of the corpse will not produce such a phenomenon .”

"Then what's your opinion?" Zheng Yan asked, frowning.

"I don't know either." Qin Ling shook her head, "This is not the only doubt. On the other corpses, some of the tendons have been severely damaged, and some of the bones and joints have been severely damaged. This is all related to their bodies. The degree of corruption does not match. Moreover, the corruption points are all on the feet. I suspect," she frowned and thought for a while, "the reason for this obvious difference and specific signs of corruption may be that these corruptions have already started before the victim's life. , to be more precise, it should be festering. However, what causes this festering is not yet known.”

"Look, how is this ulcer different from the ulcer on the victim's foot?" Tang Hegong said, suddenly bent down to take off his shoes, even the socks, and a strong stench dissipated in an instant, even overshadowing the corpse. Rancid.

"Boss, your feet really hurt." Zheng Yan covered his mouth and nose, looking like he was about to faint.

Qin Ling was not affected at all, she looked down and looked at Tang Hegong with a strange expression: "Teacher, your feet?"

"How is it different from the ulcers on the soles of these people?" Tang Hegong asked after putting on his shoes and socks.

"It should be said..." Qin Ling chose her words carefully, "If you reverse-restore the ulcers on the soles of these people, your current situation should be the same as their early condition. Teacher, what is going on?"

"Diabetic foot." Tang Hegong said, "I have reason to believe that these victims may all be terminally ill with diabetes and have reached the point where they are dying."

"Old Crow Tang, what about you?" Zheng Yan also looked at Tang He Gong in disbelief.

"Me? What can happen to me?" Tang Hegong laughed and said, "I'm just an early diabetic foot, and if I treat it properly, nothing will happen."

"Inappropriate treatment may kill you." Du Li's cold voice came, followed by the click of her characteristic high-heeled shoes hitting the ground, the door of the dissection room was pulled open, and the dusty Du Li walked in and said with a cold face, "Diabetic foot is a serious complication of diabetes, and it is one of the important causes of disability and even death for diabetic patients."

Probably did not expect Du Li to appear at this time, Tang Hegong was speechless for a while, scratching his head embarrassingly, and smirking.

"Boss, I'm not joking with you." Du Li said with a sneer, "I don't want to see you appearing in a wheelchair one day."

"Don't listen to Dr. Du's nonsense, it's not that serious. The doctor has already said, as long as I pay attention to it, it will be fine." Tang Hegong said to Zheng Yan and Qin Ling.

"By the way, Doctor Du, what did you find out on your trip?" He asked Du Li again.

"Affirmed my previous speculation." Du Li said, "I found those explorers and asked about what happened that night. I can confirm that the haunting is purely fictional. The scenes that each of them saw were different. They are different, but they are all closely related to the genre novels they usually like to read, so they should be affected by some kind of medicine. Before I came, I went to the Public Security Bureau of City C and got this." She took it out of her bag A report, "Where you found a large number of dead bodies, there are residues of plant burns, the composition of which was determined to be poppies."

"Poppy, whether swallowed directly or inhaled by incineration, can stimulate the central nervous system and cause hallucinations. The suspect is obviously familiar with the use of poppy and can get it." Du Li said, "and , I noticed a detail, in the rumors of the locals, they all said that they only heard the sound or saw the candlelight, but did not see the 'ghost' with their own eyes. But in the mouths of the explorers, they all mentioned the smell, and saw it with their own eyes. I saw a 'ghost'. This shows one thing, the suspect used poppies to target these explorers. The early deduction of the police in City C was correct, and the suspect was using this method to hide his crime."

"So many people have been killed, why not kill these people as well?" Qin Ling asked this question that hadn't been answered before.

"My silly Reiko." Du Li smiled, "He killed those people in secret, no one knows. But these explorers made great fanfare before the expedition. If they disappeared or died during the expedition, you said the police would You won't find out here? But if they say they've met a ghost, will you pay attention?"

"However, these are useless." Zheng Yan said, "except for the content of poppy. Poppy is a controlled product. Although it is not as difficult to get it as drugs, it is not so easy. This may help us lock down the suspects. People. Others, I don’t think it’s meaningful.” He ignored Tang Hegong’s restraining eyes and said to himself, “Xiaoxue, don’t you think so?”

"It's impossible for Sister Lili to go out to investigate because of such a trivial matter. I think there must be a more important purpose, right, Sister Lili?" Mu Xue unexpectedly did not cooperate with Zheng Yan.

"No, I just ran out because of such a small matter." Du Li said, but seeing Qin Ling and Tang Hegong with pleading eyes in helplessness, she still sighed in her heart and said, "Okay, Actually, I was here to verify another thing.”

"Lingzi, have you told them?" Du Li asked Qin Ling.

Qin Ling's eyes were a little dodged at the moment, and under Du Li's gaze, she seemed to muster up the courage to look at her, and said, "I think it's more appropriate for you to say, I just told them your conclusion."

"Okay." Du Li sighed imperceptibly again, how could she not know what Qin Ling was thinking, "The reason why I want to verify whether what these explorers said is true is a very important one. The reason is that when they woke up in the hospital, there were more or less signs of alcoholism, and the blood alcohol content was around 300mg/100ml, with an error of no more than 5mg/100ml. The attending doctor also confirmed this. But they denied it After drinking, there is no smell of alcohol on the body."

Hearing what Du Li said, Zheng Yan was taken aback for a moment, showing a pensive expression.

"That's right, I think the suspects injected alcohol into their bodies by injection." Du Li said, "But it's not just a matter of technique, it's more about experience. Everyone's physique is different, and the same After a glass of wine enters the body, the alcohol content in the body of different people is not the same. A good doctor also needs to use a variety of instruments to detect. But at the time, the suspect obviously did not have such conditions. But he did it easily."

"I probably know the identity of the suspect." Zheng Yan raised his head and looked at Du Li. "Dr. Du, I have one last question. Are the mung bean fly maggots useful in medical treatment?"

"Mung bean fly?" Du Li frowned, and suddenly smiled, "You mean Lucilia sericata, right? Lucilia sericata is the mother of medical maggots."

"Maggots? For medical use?" Tang Hegong looked at Du Li in a daze.

"That's right." Du Li nodded, "The use of maggots in medicine was invented by the ancients. It is called maggot therapy in medicine. It is to use medical maggots to help clean up festering wounds and eat the necrotic tissue that hinders wound recovery. It is a natural biological therapy with bacteria. In the middle of the 16th century, people discovered that the fly maggots on infected wounds would not aggravate the infection, but were beneficial to healing. In the 19th century, Napoleon’s army used this method to treat wounded soldiers. , and extended this method to the American Civil War and World War I. It was not until the 20s that the emergence of antibiotics made the maggot treatment method abandoned, and using maggots to treat diseases became a simple and unscientific method. In fact, researchers have shown that maggots can clean large, difficult-to-heal wounds faster than surgery, and many doctors are now calling for the reintroduction of this therapy."

"Boss, in addition to conventional treatment, you can also try this treatment." Du Li glanced at Tang Hegong and said.

"I won't try it. I'm afraid that the illness won't be cured, and I'll die of nausea first." Tang Hegong said shaking his head like a rattle.

"Thank you, Dr. Du, I have now found the answer to the question that troubled me the most." For some reason, Zheng Yan's very ordinary words sounded inexplicably more compassionate to the rest of Team Z.

"Go and ask Team Leader Chen to come over, he has the right to know the next analysis." Zheng Yan said.
