"Markor, look, in abnormal death cases, it is important to find out the cause of death, and then simulate the crime process based on the wounds and scars of the deceased. The body was soaked, and the gun was obviously found on the shore, but the victim may not have been shot by the gun, so the ballistic test will be performed."

Avis ran down the dissection table, went to the vicinity of the chemical mass spectrometer, and took a test strip, cotton swab, and test tube solution. "Uncle Nai, have you done gunpowder test before the ballistic test?"

Nezhel looked up coldly and said, "I've done it, you can try it for him."

Ives learned this trick from Neil.

When Neil brought the new bird Ives, he spent most of his time in the Criminal Investigation Science and Technology Office, and ordered Ives to run to the forensic mark examination and forensic doctors, either carrying this one and that, or passing messages at both ends.

Avis was unconsciously influenced by his eyes.

In the Criminal Investigation Science and Technology Department, I learned a lot of valuable knowledge, which is much more interesting than boring books.

Hands and eyes are in harmony, and it is impressive.

Not to mention, there is always a body waiting to be dissected or being cut at the dissection table...

Heavy taste, thriller, curious element, the one that hits Ivis is right!

On the contrary, the purely written laws and regulations made Avis want to harm himself...

He gently wiped the muzzle and the handle with a cotton swab and soaked it into the test tube solution.

After gently shaking evenly, carefully immerse the test area of ​​the test paper head into the solution and take it out.

After waiting for a while, the test strips turned red.

"This gun has been fired recently, and there are gunpowder residues. Of course, it was fired during the ballistic test. I'm just showing you a demonstration. If you find a gun at the crime scene, you must be careful to wear gloves and hold the tail of the buttstock. Maybe it's all about evidence, right Uncle Nai?"

Avis communicated enthusiastically with the terrifying forensic doctor.

Unfortunately, the other party didn't appreciate it, so he said depressedly:

"The residue of gunpowder cannot indicate who opened it. I need DNA and fingerprints!"

"There are other residues on the barrel, sticky, you must have seen it!"

Ivis answered sensiblely, with a ease and comparable to the senior agent.

Naizel was a little surprised and praised her for her head-up. The ridges of the head-up lines folded and stretched at the same time. He said patiently:

"The remaining fragments of the barrel are bones, probably skulls or frontal bones, close-range, headshots, and the fragments are stained with brains."

"See Marcole! The Criminal Investigation Technology Office is full of talents! It's amazing! Shooting is not standardized, and relatives are crying, and shooting their heads in close proximity will leave so much evidence. I didn't expect it! Isn't surprise! Isn't it perverted!"

Aigou is dancing and enjoys it, and has a sense of accomplishment.

Not only did he show off his reputation as a silly scattered man, but he was also recognized by Nezel, the forensic doctor in the underworld.

Avis was thick-skinned enough to stay until the forensic doctor Naizel rushed to get the person and was willing to leave.

If not, Ivis would definitely drown the forensic doctor in the underworld with saliva.

Walking down the anatomy room, I met the oncoming Dalton.

The social bull-batch ceiling also harmed mimosa and trace chemical forensics.

"Senior brother, come and chase the evidence?" Ai Gou hooked Dalton's weak shoulder with one hand. It's a special thing.

If Dalton's toes were ignored.

"Uh..." Dalton glanced at the dull wolf cub Marcole, shrank his head and buried it in his collar. His movements were smooth and clean, and he completed it in one go, "Smith case."

“Are there any progress?”

When Ai Gou heard that it was Lao Shi's case, his face pulled down and immediately restrained his unrestrained pride and changed into a heavy tone: "Nezel just said that the ring was taken out of the deceased's stomach, but there seemed to be something in the gap above, and it was still with the chemical granule interns. Let's go there together."

"good……"

Not good at all... Mimosa just wants to handle the case quietly, but does not want to cooperate with the social giant. Moreover, the data retrieval and sorting of this case are not only unable to help, but also worsens.

If you want to know the progress, instead of following Dalton to hinder the case handling, it is better to go to the CMS system to check the progress more thoroughly and cleanly.

The chemical certification room is a semi-open space, with racks on both walls, filled with bottles and jars - test tubes, beakers, drop bottles, test tube racks...

Responsible for the forensic business of trace substances, chemical elements, microparticles, etc.

Marcole and Ivis were both tall and strong, and walked with wind. Dalton was afraid that they would smash these equipment.

"Sebenna! I'll get my ring! Have you finished testing it? The auction will be tomorrow night!"

Avis shouted.

One of Neil's personal disciples, Sai Benna looked up exhausted -

OK! The most annoying super special police officer in the entire Criminal Investigation Technology Department is here!

He was ignorant and careless, and asked endlessly what he saw, and he was polite. He also wanted to collect kidney stones in the victim's body and raise the long-lasting worm that ate the victim's brain...

Avis, who has a lot of bad records, actually inherited the jewelry from the Smith case. Sure enough, people have different fortunes.

It would be fine if you don’t do anything in the world. Just talking nonsense can hinder others from doing things, you can be on the top ten blacklist of the Galileo Bureau of Investigation!

"Don't you need physical items at auction? You will buy it back at a high price anyway."

Sai Benna said expressionlessly.

Mimosa Dalton of the special tuned game sent a piece of oil paper with special ingredients yesterday, and a fur - a pure aries wool vintage coat.

There are too many things at the murder scene and there are few people with biochemical forensics.

Neil has promised to come back tomorrow to move bricks, but the other detectives have put their case first, and everything is more important than the sky. The young people who have chemical forensics have accumulated a lot of holidays, and are waiting for Neil to come back to queue up to apply for annual leave...

"Oil paper is made of tree fibers rich in epoxy resin. It has a long process and exquisite craftsmanship. It has been more than 130 years, which is in line with the craft materials used in that era. However, this piece of oil paper is obviously a more detailed process, fully handmade, and special uses, such as preserving very expensive fabrics, books and other soft substances, which can seal and avoid light, keep humidity and temperature constant, and have miraculous effects such as antibacterial."

"Yes... Lao Shi was a disciple of the treasure appraisal master. It was not surprising that they made this oil paper a hundred years ago to preserve valuables. He liked to make these boring things."

Avis was slightly sad, thinking of the old bald man who was honest and honest in business, and was a little sad.

“Epoxy?”

The biological method of looking at the microscope on the other end of the laboratory bench confirmed that the intern looked up, "It's just yellow tree oil, it's very common in tree oil. The lost technology in the past is really amazing! I actually know that using this method to create this effect oil paper."

"When it comes to big trees, there are indeed a few big trees that have been more than a hundred years old next to Old Smith's loft. Did they use that?"

Aigou spoke out and planned to help.

Regarding this information that was not helpful to the progress of the case, the intern of the Bioscience Law proved that he did not despise Baibus Water for his speech and explained seriously:

"Those trees are northern dogwoods, belong to broad-leaved trees, and only the pine family has yellow tree oil."
