The conclusion of the autopsy was similar to the preliminary conclusion at the time of the discovery of the body.

"How well does the fatal wound match the sharp knife found at the scene?"

"The corpse was too badly decomposed, but from the part of the heart that had not yet dissolved, it was certain that the murder weapon was a sharp knife."

The situation Wang Changjiang said was explained from the perspective of forensic medicine, and the meaning was also very clear, that is, it was not 100% certain that the sharp knife found at the scene was the murder weapon.

However, from the perspective of the current survey, there are already relatively definite statements.

Liu Guodong took over: "We found blood stains in the scabbard of the sharp knife, and after examination, we can confirm that the blood type is consistent with the blood type of the corpse."

"However, the activity of the blood stains disappeared, and we used a trace physical evidence testing instrument to identify it, but the genetic material was not successfully extracted, and there was no way to conduct DNA comparison."

"However, combined with the judgment of the forensic doctor and the analysis of the bloodstains......" Liu Guodong and Wang Changjiang glanced at each other, and the other party nodded.

"Basically, it can be said that the sharp knife found at the scene should be the murder weapon."

The case analysis meeting is not only a conference for speaking freely, but also a conference with rigorous thinking and logic.

In particular, when forensic doctors and current investigators report, they must not pay attention to logic, but must also talk about evidence.

In the criminal investigation industry, forensic medicine and field investigation are the basic buildings of economics.

It is the logical basis for the reasoning and handling of cases by the front-line criminal police.

Many clues have been found in the Bailanhe rotting corpse case, such as the murder weapon, such as the cause of death, such as the first scene of the abandoned corpse.

But critical information is still missing.

The identity of the deceased has not yet been determined, and investigations in the vicinity have found nothing.

In addition, the body may have been dumped by the murderer in the Bailan River, and the murder weapon was abandoned at the place where the body was found, everything is full of strange things that do not conform to the logic of ordinary people.

On the banks of the Blanc River.

Lu Chuan is conducting on-site investigation at the moment.

"Xiao Lu, how is it? Did you find anything?"

Liu Guodong was in a meeting, and Yang Sen and Lao Bai followed Lu Chuan to investigate the scene where the murderer abandoned the body.

Due to heavy rain, the traces under the bushes are very unclear, and there is basically nothing to be found with the naked eye.

But after the rain stopped, the faint smell of corpses still loomed, reminding people of what once existed here.

Lu Chuan is using instruments to conduct a detailed inspection of the site, and he has already made some discoveries.

And the corpses are rotting here, and the corpse oil soaked in the soil cannot be diluted by a heavy rain.

"Some hairs have been found, others have not been found yet."

From the professional perspective of on-site investigation, Lu Chuan is far more professional than Zhang Hui.

Zhang Hui could find that the body had traces of dragging according to the position of the shoes, and Lu Chuan could naturally find it.

However, the body is now highly decomposed, and the scene has been washed away by heavy rain, and the footprints left by the murderer have long since disappeared.

Although the first scene of the body has been found, it does not seem to be of great use in solving the case.

Criminal Investigation Detachment.

"What about the results of the investigation of the clothes on the corpse?"

The clothes on the corpses, especially the underwear, are expensive, and there is a gap between the size and the real body of the corpse, which is now the most important clue to be able to trace the identity of the corpse.

In charge of this investigation is Sun Jun's operational team.

"The white cotton long-sleeved shirt, with a pure brand, is a spring shirt that was launched in March last year."

Sun Jun began to report on the results of the investigation.

"We checked 18 Yichun specialty stores in Haizhou City, and all of them sold this kind of compassion the year before last."

"When was the clothes discontinued, when were they discontinued, and can you find out who they are selling to?"

Sun Jun smiled bitterly and shook his head: "This is the hot shirt in the spring of the year before last, the price is cheap, when it is not discounted, it is 99 yuan a piece, and then it is only 39 yuan when it is the cheapest."

"We looked at the sales volume and the average sales per store

There are more than 300 pieces, and there are almost 5,000 pieces in total."

"The clothes on the corpse were size S, and it was also the size that sold the most, almost a third, or almost 2,000 pieces."

"The sales time is mainly concentrated from March to November of the previous year, and a small number of them were cleared before the end of June last year."

Sun Jun's group of investigations was very meticulous, one day and one night, more than 20 people, running all over the Yichun stores in Haizhou City.

But the result is a bit devastating, there are too many of these clothes.

But Sun Jun's words were not finished: "This still does not count the sales of online shopping, and it is difficult to count this part in a short period of time."

"In other words, it is difficult to find out the identity of the corpse from the shirt it wears?"

Qin Yong's brows furrowed tighter and tighter.

"For now...... Yes."

"Where's the corset?"

Speaking of the corset, Sun Jun has a spirit.

"This type of corset is easier to find."

Sun Jun stood up: "The brand of the corset worn on the corpse is called Secret Garden, it is a foreign luxury clothing brand, the price is relatively expensive, and there is only one specialty store in Haizhou City."

"But there are also more sales channels for this underwear on the Internet, and there are some sales in Haizhou, so it is not easy to investigate."

"In addition, this underwear is a new model that was only released last year, and the price is 1,388, and the local sales in Haizhou City are not much, and the sales of the D cup are even smaller."

"This is a list of all the people who bought this corset D cup offline in Haizhou."

Qin Yong straightened up from his chair and carefully looked at the list of people who only had thirteen people.

"Have you checked it all?"

"Three people have been checked, and the others are continuing."

"Good!"

"Keep an eye on these thirteen people and investigate them in the shortest possible time!"

"Yes!"

This is the best news Qin Yong has heard since the case.

The underwear on the corpse can basically be determined, and it is not the corpse itself.

There are two reasons for this.

One is that the size is inconsistent, a B-cup woman will not wear D-cup underwear.

Another reason is the cotton t-shirt worn by the corpse.

T-shirts are cheap, and judging by the degree of wear on the cuffs, the other party should wear this t-shirt often.

What does this mean, it shows that the deceased's economic conditions are average, and a shirt can be worn for two or three years.

So, would such a person buy a bra for more than a thousand pieces?

However, having clues does not necessarily solve the case.

Five days later.

Conference room of the criminal investigation detachment.

"Thirteen people have checked?"

Sun Jun, who was sitting opposite Qin Yong, didn't look good either.

"I've checked everything, everyone has checked it, and among the thirteen people who bought bras, there are two men and eleven women."

"One of the men was bought for his wife, and the bra is still there."

"The other one was bought for a lover, and although the woman is out of town, she has confirmed that the bra is still there."

"The other eleven women, some bought for themselves, some for friends, we have checked, and the bras are all there."

The most likely clues, but no valuable information was obtained.
