National Forensic Doctor

Chapter 673 Awesome knife

Eat fish in the evening.

During the day, the corpses were collected from the sewage pool, which made many people feel slightly uncomfortable. At night, they could only eat some aquatic animals, such as Eastern star groupers, swimming crabs, hairy crabs, nine-segmented shrimps, and oral mantis shrimps of the family Decapoda. Wait, this time it's Jiang Yuan's treat, and it won't use Zhengguang Bureau's funds, so that Tao Lu and others can feel better.

Tao Lu walked down the slope, linked arms with Huang Qiangmin, and talked for more than ten minutes with a blushing face.

The case must continue. At this time, no matter how harsh Huang Qiangmin's request is, Tao Lu may agree. Therefore, after the final conditions were met, Tao Lu even felt that Huang Qiangmin's request was not so special and excessive.

Jiang Yuan ignored them and ate half of an Eastern Star Spot like a whirlwind, peeled off a swimming crab, and mixed half a bowl of rice with Pippi shrimp, two spoons of Lao Gan Ma and a little mustard. He wiped it with his mouth and said: "I'm going to see the body."

Tonight is destined to be a sleepless night. Before work time tomorrow morning, the task force will prepare the autopsy report. Otherwise, other members of the task force will have to wait for the report before they can work.

Jiang Yuan doesn't care too much about staying up late. Just like doctors always tell their patients to have a good rest and eat lightly, they actually overeat and stay up all night. Many doctors actually see too many people who get sick for no apparent reason.

Forensic doctors are actually the same. For example, the six corpses this time. Although they had sex, drank, stayed up late, and some might even smoke, they were all very young corpses. Normally, they were still far from dead.

And each of these six people has no reason to die.

They just chose a way of life.

Strictly speaking, the murderer can also explain that he has chosen a lifestyle, but his lifestyle has obliterated the lives of other people. At this time, someone should stand up and retaliate, an eye for an eye.

"Did you find anything?" Jiang Yuan picked up a large food box and placed it on the free table.

Old comrade Zeng Lianrong smiled with a good attitude and said: "I just did some examinations and measurements. The data are all in the book. The two deceased, No. 5 and No. 6, were both women. Among them, No. 5's knees also had a certain amount of pain. Wear marks, suspected to be caused by exercise..."

Zeng Lianrong didn't look at the record book. He just described the conclusion he came to and then gave up his position to Jiang Yuan.

Jiang Yuan nodded and stood in front of the autopsy table without hesitation.

The corpse with only bones left does not need sharp objects such as scalpels. The dissecting table itself is clean and maintains the shine of the metal.

However, few medical examiners would like such a corpse.

Everyone would rather have fresh, trembling flesh that will look trembling when photographed. It is easy to do and it is easy to draw conclusions. It is not like bones and bones. If it is clean, it will be clean. No useful results can be obtained, and it is all in vain.

Jiang Yuan looked at the bones on the dissecting table one by one. When he saw the knee, he said: "The knee of corpse No. 2 is also very worn."

"Yes, and it also looks like a sports injury." Zeng Lianrong specifically raised this point just now, taking this situation into consideration.

Among the six corpses, there were four female corpses, and the knees of two of the corpses had sports injuries. This proportion is a bit small to make a definite inference, but it certainly cannot be ignored.

Jiang Yuan carefully looked at No. 5's knees, and asked No. 2's knees to be taken out for comparison, and then said: "The type of exercise performed is different, and No. 2's injury is more in line with weight-bearing training." .For size 5, it is more suitable for sports such as running and walking.”

Zeng Lianrong could actually see that, and immediately nodded and said: "I agree. However, if you are exercising in a gym, both are consistent."

"Indeed." Jiang Yuan was noncommittal. In this case, it is assumed that the victims were all invited through social software. From this, it is unlikely that the victims are from the same area or even the gym, unless they are all local residents. But this is inconsistent with the missing persons report information.

The little forensic doctor Zhan Kong and others next to them were listening to the conversation between Jiang Yuan and Zeng Lianrong, while they stretched their heads and looked at their knees, pondering their thoughts.

The forensic industry is somewhat similar to the antique industry. Many things need to be seen, touched, and constantly stimulated in a positive way to form a concept.

For example, if you compare a knee with a sports injury using the instructions in the book without touching the real thing, it's almost like guessing. Only when you see more and see more can you make confident judgments. Of course, this must be based on anthropological theory.

Just as Zhan Gong was looking at his knees, Jiang Yuan picked up some of No. 5's vertebrae and looked at them.

Zeng Lianrong came over immediately, moving faster than the little forensic doctors.

"You also discovered it." Zeng Lianrong didn't wait for Jiang Yuan to speak, and first told the answer to the mystery.

Several junior doctors looked over without knowing why.

"You mean scratches?" Jiang Yuan placed the first thoracic vertebra alone to the side.

Zeng Lianrong laughed, nodded and said, "Yes, the scratches are very thin. You can't see them without looking carefully. What tool do you think caused it?"

"It's a great knife. A single-edged one, with a slight curvature, pointed, thin blade, sharp..." Jiang Yuan said in one breath the various characteristics of the blade that caused scratches.

Zeng Lianrong's smile faded little by little.

"How do you see the single blade?" Zeng Lianrong asked.

"Look, the indentation is uneven." Jiang Yuan handed over the horseshoe mirror.

Zeng Lianrong asked: "Where is the tip?"

"There is a pause." Jiang Yuan pointed to the location. There was a small pit slightly downward in the bone here. Under the corrosion of sewage, it was almost indistinguishable from the normal depression.

Zeng Lianrong looked at her for a long time before sighing: "Your eyes are really good."

"Young." Jiang Yuan said humbly and harmoniously.

Zeng Lianrong smiled and his expression gradually calmed down. He could see that the scratches were very thin, and he guessed that it should be a single-edged knife. From the thickness of the scratches, he guessed that the blade should be very thin, but that was all. Whether the knife was sharp or curved, he Didn't see it.

These two points actually determine the type of knife to a large extent.

Just like Jiang Yuan blurted out "a great knife", two words can save a lot of investigation time, as well as the police force of the task force. In the process of racing against time to solve the problem, it is very meaningful and definitely reflects the forensic skills.

"The knife was scratched at the thoracic vertebra, it doesn't look like it was stabbed in..." Zhan Kan had at least a 0 level of forensic pathology, and after making two gestures, he could see something abnormal.

Zeng Lianrong glanced at Jiang Yuan and said again: "These are the traces of dismemberment."

"Hey, No. 5 was dismembered?" Zhan Gong was surprised.

"It's possible that the body was already a little stiff when it was put into the bamboo basket, so it was divided into several pieces to put it in." Zeng Lianrong saw more and immediately said a possibility.

Jiang Yuan said: "It's still a bit difficult to divide a body with a bull's knife."

"Do you have a medical background or experience in butchering?" Anyone who has killed someone knows that without skills, it is best to use an ax to dismember a body, or at least a thick-handled bone-chopping knife. Dare to use a machete to dismember a body and leave only very shallow knife marks. This is a relatively superb skill.

Jiang Yuan nodded slowly.

Zhan Gong was slightly excited: "At least it has narrowed the scope to a certain extent."

"See if there are any traces of dismemberment on other corpses." Jiang Yuan changed a pair of gloves and said: "If the corpses were dismembered with a knife, the marks may be very shallow. All places similar to knife marks must be carefully inspected and Mark it out.”
