Han Da'er found that there were many dry bones in the well, many of which did not have skulls, and there were no skulls with parietal bones, and there were very few broken bones in the broken bones, as if they had been cut open by a sharp blade of a knife and axe. Although the strange man in the well had gnawed corpse bones, he had no sharp blades with his bare hands. Moreover, the skull is the hardest of all human bones, and although the skull has been crushed and broken by a blunt instrument, it is impossible to cut the skull so neatly without a sharp blade.

Han Daring divided the bones into ages according to the appearance of the old and new eras, put them in batches in a large basket, tied ropes, and pulled up the wellhead by Zhang Biao and Liu Fang. The bones were then transferred to a canvas laid out inside the car.

Since the case has not yet been filed, and it is nearly a year old, Han Da'er does not want to cause panic, and he wants to investigate secretly, but Nanshi is densely populated, and if he picks up bones and transports corpses on a large scale, he may alarm the murderer. Therefore, the whole process of picking up bones and transporting corpses was covered with a white cloth sheet and quickly loaded.

Originally, this small courtyard has long been deserted, and no one lives in the courtyard, but this is the New Year, every household is busy with the New Year, people come and go in the alley, and there are many children, the firecrackers are dismantled, the firecrackers are set off in the alley, and the news that the police are tinkering in the small courtyard is still spreading.

When Zhang Biao saw everyone watching, he casually deduced that there was a recent epidemic of typhoid fever and malaria, and that the well in the hospital was not clean and could spread infectious diseases, so they came here to clean and disinfect. But this nonsense is said without brains, and the common people are not stupid, so no one believes it.

At this time, a gust of north wind blew, the white cloth list on the basket was blown away, a basket of white bones appeared in front of everyone's eyes, the surrounding people were immediately frightened to hide away, everyone talked about it, saying that there were ghosts in this yard, some said that there were goblins in the yard, these white bones were left by goblins eating people, and some said that there were zombies in the well, and zombies had become corpse demons.

The neighbors shouted blindly, which annoyed Zhang Biao, and scolded and reprimanded, saying that whoever watched Hu Qin again was involved in these bones, and they should be arrested and punished together.

The people are afraid of officials, and it is not uncommon to catch cases and take innocent people to the head of the people after they have been caught on errands that year. In the early years, because of the Tianjin teaching case, those heads were cut off, and most of them were innocent people who were arrested to resist their crimes. Zhang Biao looked vicious again, as soon as he said this, the people immediately avoided from afar, and some good things hid in their own yards, and they couldn't help but look here.

It took a whole afternoon to collect bones and move corpses, until it was almost dark, and all the bones at the bottom of the well were collected. Han Daring led people to move the boulder that crushed the strange man away, and collected the corpse of the strange man that was crushed to pieces.

Don't look at You Fei, the others are all old policemen, and when they see such a tragic corpse, they can't help but vomit. This strange man sacrificed his life to save Han Da'er's life. He couldn't bear to throw the strange man into the hole, and he wanted to find out the identity of the strange man, so he threw a canvas in the basket and shoveled the corpse and flesh into the basket little by little.

Han Dada'er finally investigated the bottom of the well, and saw that all the clues had been collected, so he climbed to the mouth of the well. When I left the small courtyard, I saw that the surrounding residents were all looking out and whispering, knowing that the news of picking up bones had spread.

He originally thought that since there were both old and new bones in the well, the murderer must be a habitual offender, and he must often throw the corpse in the well, if he can't find the murderer for a while, as long as he secretly collects the bones and does not leak the news, or he can set up an ambush in this place, maybe he can directly capture the murderer when he throws the corpse next time.

Now it seems that there is no unventilated wall in the world, not to mention that this matter is not easy to keep secret, since it has spread, the murderer will definitely not come here to throw the corpse again, so he directly sealed the gate of the small courtyard and transported the bones to the epidemic prevention hospital.

Han Da'er and You Fei followed the car to send the bones to the epidemic prevention hospital, while the others went to take a bath to remove the rancid mud from their bodies, and then disbanded directly from Nanshi and went home. When I went to the bathhouse, I saw Fan Tong walking out of the bathhouse with a big red face.

It turned out that this kid, after waking up, found that everyone was gone, leaving only him to account, the more he thought about it, the more worthless it became, and went back to wash it several times before he felt that it was enough, but he soaked in hot water for too long, and he was directly dizzy, thanks to Uncle Wang, who was rubbing the bath, was quick and quick, or Fan Tong would have drowned in the pool at this time.

The hospital is usually deserted, but now it is overcrowded. Recently, there has been an epidemic of typhoid fever and malaria in Tianjin, and many seriously ill people have been isolated in epidemic prevention hospitals for treatment.

Fortunately, there is a back door on the first floor of the hospital, and the corridor on the first floor is separated by wooden boards, which encloses half of the corridor and directly connects with the wards and treatment rooms on the second floor. The other half is close to the entrance to the old Su Ju and the underground morgue, and the two are not disturbed.

However, for the sake of epidemic prevention and safety, it will also be cremated immediately after the report is made, so as to avoid the accumulation and decay of the corpses due to the epidemic, and the regeneration of other infectious diseases.

Han Daring and You Fei carried the piles of bones to the ground and stopped for a while, and found a stone platform neatly stacked in the corner. Lao Su saw so many bones, knew that there was another big case, and he didn't dare to slack off, and just after examining a hanged corpse, he immediately began to examine the bones.

Although You Fei and Han Daring have been to the epidemic prevention hospital twice, they have been waiting in the hospital each time, and this is the first time they have come down to the morgue. The smell in the morgue was unpleasant, especially the body that had hanged itself, giving off a foul smell.

It was the middle of winter, and the morgue was underground, which was even more cold and bitter, because when the hanged body was found, it had been dead for nearly a month, and it was stuffed indoors, so even if the weather was cold, it had already begun to decay and decompose, and a lot of viscous corpse water and corpse oil flowed out.

Although You Fei was almost disgusted, he still suppressed the disgust, and helped Han Da'er and Lao Su try their best to put together the bones one by one, but the bones were scattered, and less than one percent of the bones could be completely pieced out, and the others were no longer recognizable, so they could only roughly estimate the time and age of the bones according to the thickness and tenacity of the bones, and then stack them neatly according to the time.

Among them, any bones that can find some clues will be marked and examined one by one.

Although Lao Su is old, his hands and feet are very sharp, his bone examination techniques are skillful, and although there are many corpses, he is meticulous in every examination. While examining the bones, he told Han Daring and the others about the knowledge of the bones.

For example, the metacarpal bones of bears are similar to human metacarpal bones, some turtle shell fragments are very similar to human skull fragments, and the ribs of sheep and deer are similar to human ribs, so even if it is a whole human bone, as long as it is not a bone fascia that is still connected, but a scattered human bone, it needs to be carefully examined to avoid other animal bones being mixed with it.

The bones sent by Han Da'er can basically be concluded to be human bones, and there are no animal bones. After that, the skeleton is examined to determine the sex, age, height, and so on of the deceased.

For intact human bones, the success rate of the presumptive sex is close to 100%, and the error of the presumptive age is 5 to 10 years. The height error is within one inch and two minutes. Since Tianjin Wei is a nine-nation concession, it is also necessary to judge the race when the bones are examined.

These underground skeletons are of different heights and genders, but they are basically of Mongolian race. There are four major human races in the world, namely the race (yellow race), the Europa race (white race), the Negro race (black race), and the Oceanian race (brown race).

The underground are all, that is, yellow people. The Japanese are also considered to be yellow, and Nanshi is next to the Japanese concession, and it is not excluded that there are anti-Japanese soldiers who secretly assassinate the Japanese and throw them into the well. However, at that time, the Japanese were quite short and most of their teeth were uneven. These bones do not have this characteristic, so they can basically be inferred to be Chinese.

As for the age of the bones, the bones of juvenile children are more accurate than those of adults, because the teeth and bones follow a certain growth trajectory and maturation pattern, and the age range can be greatly narrowed according to the stage of development of the bones.

Some people think that as long as there is a skull in the skeleton, the size of the skull can be used to determine whether a child or an adult, but this method is actually not accurate, because for example, the famous dog rotten "little head" skull in Tianjin Wei is much smaller than that of an adult, so this method is not accurate.

Examination of the teeth is a way to determine the age of the bones.

Children also have 20 baby teeth, while adults have 32 permanent teeth in addition to wisdom teeth, and the loss of baby teeth and permanent teeth appear at the age of 12, while the wisdom teeth mostly emerge at the age of 18. If the bones have a pair of permanent teeth but no wisdom teeth, the age is roughly between 12 and 18 years old, but this method is extremely inaccurate because the timing of wisdom teeth eruption varies from person to person.

However, the degree of wear and tear of the teeth due to chewing food varies according to age, so the age of the deceased can be roughly inferred from the degree of tooth wear.

However, if there is no skull, there are no teeth to see, and the age can be judged by the long bones of humans. The so-called long bones are the bones of the human limbs, which are long tubes, with the backbone in the middle and the epiphysis at both ends.

In addition, the laryngeal bone ossifies and hardens with age, and the pubic symphysis is located at the anterior junction of the two pelvic bones, which will straighten and narrow with age. The sternal junction of the rib cage is smooth and rounded when young, and although it becomes pitted over time, the edges of the holes will be sharper.

By looking at the ends of the third, fourth, and fifth ribs and monitoring their junctions, the age range can be narrowed down from 28 to 30 to 65 to 70. As we age, the calcareous bones also become brittle and thin at the end.

According to the characteristics of tooth wear, the closure of the growth plate of the long bone, the ossification of the laryngeal bone, and the closure of the rib end and pubic bone, it is generally presumed that the bones are basically adults, aged between 20 and 35 years old.

Lao Su inspected them one by one, at first You Fei also assisted with Huan Dadao'er, but then You Fei couldn't keep an eye on it, so Han Dada'er let him go home first, and he continued to follow Lao Su to inspect the records.

The bones died in different order, and the bones found near the stone lions in the cave were three adult males. The time of death is the earliest, the bones are badly decayed, and they are already very fragile, more than fifteen years old. The bones of the rest of the dry wells are stacked at the bottom of the dry well, men and women are of different heights, the earliest batch of bones has died for at least ten years, and the rest of the bones are in chronological order, and the latest batch of bones is only two or three months.

There are more than 100 bones, and the older they are, the fewer the number of bones, but the number of bones that have died in the past two or three years is staggering, and there are nearly half of them. These bones have many gnawing marks on them, whether they are skull ribs, long bones, finger bones, and foot bones.

The body of the strange man was crushed by the boulder, and although the skull collapsed, the upper jaw and mandible were basically intact.

When Lao Su was comparing the teeth, he cut open the skin and muscles of the strange man, took out the skull, and put the broken bones together one by one, but at this time there were two amazing discoveries!

Although the strange man's facial features are deformed, the facial features and cranial features of the skull are not traditional Mongols, but are between the Mongols and the Europa, in other words, this strange man is a mixed race, commonly known as a hybrid.

Not only that, but although this strange man is tall, he only has twenty baby teeth, but these baby teeth are very strong and grown, and none of them fall out, so they look like permanent teeth, which means that this tall strange man is actually not yet twelve years old!
