Chapter 55 Inspection

After Feng Xiaoxue and Yang's mother left, Yang Qiuchi closed the door, found an iron rod, and pried the lock on the aluminum alloy cabinet, and there were three cardboard boxes inside, intact, and when he opened one of them, it was his laptop! Attached to the computer is a miniature printer and a miniature wireless pinhole camera, but this wireless camera is only effective at a distance of 200 meters.

Yang Qiuchi took the other two cardboard boxes and opened one of the large cardboard boxes, which contained solar panels and batteries, which were specially provided in view of the fact that the Ali region of Tibetan province often has to go to the countryside to survey the site. Seeing this thing, Yang Qiuchi's heart was much more steady, at least, the laptop didn't have to worry about running out of electricity.

This computer not only has a lot of A pictures that I have worked so hard to create, but also several very important forensic software, such as fingerprint and other trace comparison software, avatar restoration software, etc.

The other cardboard box contained a forensic physical evidence investigation box, and as soon as he saw this thing, Yang Qiuchi's hanging heart relaxed.

This forensic physical evidence investigation box is a treasure, don't look at his small size, but the commonly used forensic investigation equipment and reagents are available, including miniature microscopes, fingerprint brushes, tapes, scalpels, blood collection needles, double concave glass plates, magnifying glasses and other small forensic physical evidence extraction equipment, fluorescent fingerprint powder, ABO blood group detection reagents, standard serum, old blood stain detection reagents and other forensic examination reagents and powders. With these things, general forensic examinations are fine, and these do not require electricity.

It seems that what is flattened under the boulder is mainly a full set of DNA equipment, including more than ten kinds of instruments such as DNA extraction instrument, PCR expansion instrument, and 310 type gene analyzer. However, even if these devices are not lost, they will not be used when they are brought back, and the power provided by the solar battery is far from enough to drive these things.

Losing the DNA testing equipment, Yang Qiuchi was somewhat disappointed, a good forensic doctor would have been cut off if he didn't have this set of DNA equipment, as if he had an arm cut off, but what could he do, he was not wiped out in the end. The truck was also scrapped, otherwise, this truck alone could allow the Ming Dynasty to directly enter the steam age, and now the dream is over.

It's over, it's time to get to work. Yang Qiuchi decided to check the short hair in the straw hat first, and to judge the surname of the short hair, so that he could save half of the work for Jinyiwei, to put it nicely, to minimize the degree of disturbance to the people, and also reduce the impact on the temple's Buddhist activities.

Yang Qiuchi took out the straw hat from the big cabinet, carefully took out the short hair, and performed Y chromatin and X chromatin tests on the nucleated cells at the root of the short hair, and found that it was a male hair. This test told Yang Qiuchi that he could tell Ma Du that he didn't need to arrest nuns, just monks.

The following tests are a bit tricky, but very important, and may determine whether Yin De is the murderer or not. Regarding this issue, there are three main physical evidence that needs to be identified, one is the contents of the deceased Bai Xiaomei*, one is the skin tissue fragment in her fingernails, and the other is the bite mark on Bai Xiaomei's left *.

The tooth mark on Bai Xiaomei* is currently the most valuable of the three evidences, because of the loss of DNA testing equipment, it is not possible to perform DNA tests on the contents of * and skin tissue fragments, but only for ABO blood group testing, and the latter only has the significance of exclusion, but cannot be used as evidence for the same identification.

However, tooth marks, like human fingerprints, can be used as evidence for the same identification, because the size, shape, gap, arrangement position and arch shape of human teeth cannot be exactly the same for each person, and no two people have been found to have exactly the same tooth bite marks, so the bite marks can become strong physical evidence for the same identification.

But the trouble is that this tooth mark is on the ** of the corpse, according to the requirements of forensic evidence in modern society, it can be cut off and placed in formalin for preservation, but this obviously does not work in the Ming Dynasty. Another way is to put it in the freezer and freeze it, and then use silicone rubber to make a model, which is also not easy to do, because there is no freezer and no silicone rubber. Therefore, the only way is to use a digital camera to shoot it and make it into a slide image, and then compare and test it after extracting the suspect's tooth marks in the future.

Now the first problem is to extract the comparison samples, the blood samples of Hu San and Yin De, and take pictures of the tooth marks.

Yin De's blood sample, there is no problem at all, yesterday afternoon, when Yin De was scared and fell to the ground in the mortuary, he was stabbed by an iron nail and injured his hand, and his blood was left on the iron nail and on the floor and chair of the mortuary.

Yang Qiuchi came to the main room, took the digital camera from the big cabinet, and then came to the mortuary, first scraped the congealed blood droplets that Yin De had dropped on the ground and on the chair, scraped it off with a knife, wrapped it in white paper, and then photographed the bite mark on Bai Xiaomei's left.

Yang Qiuchi went to the prison to take Hu San's blood samples and tooth marks, and when he returned home, he first compared the tooth marks, which were obviously different from the tooth marks on Bai Xiaomei**, and this bite mark was not done by Hu San. Since there are no traces of Yinde's teeth as a reference, it is impossible to make a comparison to determine whether it was bitten by Yinde.

Then, Yang Qiuchi tested the blood clotting powder of Yin De scraped back, and determined that Yin De's blood type was type A, and Hu San's blood type was type AB.

However, when he detected that the blood type of the remaining skin tissue fragments in Bai Xiaomei's nails was type O, his eyebrows were twisted together, how could this be, people's blood types are unchanged for life, which shows that the blood type of Bai Xiaomei* and the remaining skin tissue fragments in the nails are different from Yin De's and Hu San!

He stood up and paced slowly around the room, wondering if he had detected something wrong.

Yang Qiuchi was very surprised, he couldn't figure out why this was happening, that Yin De was obviously the murderer, otherwise, he wouldn't be so neurotic, all the signs were pointing to Yin De, but why were the test results inconsistent with expectations? Did you make a mistake in your judgment? Yang Qiuchi definitely doesn't believe this, he is very confident in himself, how many times there have been accidents in the past tests, but they have not surprised him, what happened this time? He didn't understand.

Perhaps, there was a problem with the inspection process. Yang Qiuchi redid Fang Cai's testing test, and the result was exactly the same as the previous one.

Yang Qiuchi's brows were tightly locked, he couldn't believe this result, it was completely inconsistent with his intuition, but he couldn't find the reason, however, he believed that his test was correct, why this result appeared, he couldn't figure it out.

Yang Qiuchi put away all the equipment and reagents such as the microscope and put them into the box, then put the 77-style pistol, small Tibetan knife and digital camera into the box, locked the box into the large aluminum alloy cabinet, and covered the cabinet with a black cloth.

You can't let others know about these things, otherwise you can't tell them clearly. The test results cannot be provided as evidence, because it is impossible for the people of the Ming Dynasty to believe in any blood type or the like, and they have to use the evidence they are used to to prove the crime, and the photos cannot be taken out, otherwise they will be burned to death as a monster.

After cleaning up, Yang Qiuchi locked the door, said a word to Mother Yang and Feng Xiaoxue, and went out. On the way, he kept thinking about Fang Cai's test results, and it turned out that this case was far from being as simple as he thought.
