"Money," Lao Meng said without thinking: "The chess and card room can only charge normal venue fees and service fees, and is not allowed to make profits from the chess and cards themselves. ”

"Uh......" Qi Yuan consciously asked a very stupid question and stopped interjecting.

Su Ping glanced at him, and then asked Lao Meng: "You just said that you didn't find objective evidence?" ”

"Well, there are still subjective indications." Lao Meng nodded and said, "I found a few bosses who were approached by Yan Zehua and then closed down to find another way out."

However, these accusations are all obviously personal tendencies, and there is no substantive basis for believing that there is someone behind Yao Ruibin, and this may not be enough as a basis for summoning and investigating. ”

"Then you can continue to check as soon as possible." Su Ping said: "When there is a result, notify me as soon as possible." ”

"Okay." Lao Meng said: "Then I'll go back and arrange the task, if it goes well, I will probably be able to give you the result tonight." If they really collude, if nothing else, at least they have to have economic dealings, even if they use the so-called safe accounts, it doesn't matter, they can be found and easy to do. ”

"It's easy to do, let's go."

After he left, Xun Mu handed Qi Yuan another report.

Qi Yuan was stunned for a moment, and as a result, he asked at the same time, "What is this?" ”

"Preliminary autopsy results." Xun Mu said: "Let's see, what have you found." ”

Qi Yuan knew that Xun Mu was testing himself again, so he responded and looked at the report.

Of course, the first autopsy results came out this morning and were conveyed to the criminal police, and Qi Yuan probably knew the content, it was nothing more than four to six hours after the last meal, the deceased drank a lot of alcohol before his death, and the cause of death was mechanical suffocation.

Qi Yuan glanced at these basic information, and saw that there was no difference, so he continued to flip back.

"Huh?" Qi Yuan frowned.

Xun Mu looked at him, the corners of his mouth raised slightly, and asked, "Found a problem?" ”

"No, Team Xun, this report ...... Did you get it wrong? It's no different from this morning. ”

"Huh? Got the wrong one? Can't you? Xun Mu was stunned for a moment, quickly took back the report and glanced at it, and then couldn't help but pat his forehead: "Hey, I really took the wrong ......"

Su Ping rolled his eyes: "This can be wrong, you are also strong." ”

As he spoke, he looked at Qi Yuan again and said, "To put it simply, Lao Qiao found two bones in the jejunum of the deceased, and they have been digested to a considerable extent.

At first, Lao Qiao was a little unimpressed, but when he sent it for examination, Lao Yan glanced at it, felt that the bone shape was a little strange, and carefully observed the articular surface of the lower bone, but unfortunately due to the relatively high degree of digestion, he could not draw conclusions, so he sent it to the anthropological laboratory for examination, and finally determined that it was human bone. ”

"Huh?" Qi Yuan was taken aback.

Immediately after, Su Ping continued: "Due to the degradation of DNA in non-living organisms, coupled with the destruction of esophageal digestion, it is quite difficult to extract DNA, so it took a long time to try for a long time before finally extracting qualified samples from the bone marrow and drawing a DNA map.

Of course, this is also due to the fact that the bone structure is stable enough to resist the erosion of digestive juices and various digestive enzymes for a certain period of time, and the degradation rate of DNA itself is also very slow.

In addition, he had a relatively serious blunt force trauma to his head, a scalp contusion, no obvious damage to the occipital bone, and no obvious pathological changes in the brain parenchyma, so Lao Qiao initially thought that he was hit by the granite stones inside when the concrete was poured.

But then Lao Yan came over to take a few looks, and after carefully studying the shape of the scalp injury, he thought that the deceased's scalp contusion, in addition to the stone smashing, should have been smashed by a cylindrical stick before that, but it was covered by the stone smashing injury, and the body was sealed in concrete for many years, so Lao Qiao didn't see it. ”

Speaking of this, he paused, obviously leaving Qi Yuan time to think.

After pondering for a while, Qi Yuan said: "There are actually human finger bones in his stomach, this obviously will not be as simple as 'taking by mistake', and even, even if he has some perverted habits, it is reasonable to swallow the bones directly into his stomach."

So it's safe to speculate that he may have bitten someone's finger off in some extreme situation and swallowed it directly.

Could this have happened at the time of the killing? No, it's not quite right, the time from the time he was pushed into the load-bearing wall formwork, to the pouring of cement, to the killing, should have been quite short, if it had been swallowed by the finger at the time of the killing, it would not have been possible to have this high degree of digestion and transfer to the jejunum.

That's when it was hijacked? It should be like this, the time is about eight hours before the killing, and it is estimated that he resisted when he was kidnapped and bit off the murderer's finger.

After that, he may have been knocked unconscious by the murderer, and the stick wound on the back of his head came from this. Then, after some time, he was thrown into the formwork, and his body was gradually wrapped in concrete. I think that's probably how it should be. ”

Xun Mu nodded lightly and said, "It's exactly what we guessed, so what does this bone do to us?" ”

"Of course, it is one of the important pieces of evidence to lock down the murderer." Qi Yuan didn't think twice.

"But whether it is Yao Ruibin or Yan Zehua, their fingers are intact."

"This suggests that either they are not actually directly related to the case, at least to Pei's death." Qi Yuan continued: "Either that, the direct murderer is someone other than them, and this person at least knew about and participated in the criminal operation to kidnap Pei Deyue.

Coupled with the feature of missing a finger, combined with the investigation of the Meng team, I think it is not difficult to screen out the suspect, and then let's do a DNA test, which is enough to confirm his criminal suspicion, and I am not afraid that he will not be recruited.

And as long as he opens his mouth, I think Yao Ruibin and Yan Zehua will not be able to run away - as long as they are also involved in this case.

Even if this guy is really angry, or has other concerns, and refuses to testify against them, they can't believe that this person really didn't say anything, and we can use the inferred information to easily create a prisoner's dilemma. ”

"Not bad, not bad." Xun Mu was very satisfied, raised his hand and patted him on the shoulder: "Although the analysis is not very comprehensive, it is quite mature. Xiao Qi, yes, there has been a lot of progress. ”

"That's pretty much the whole story." Su Ping also answered: "Since you have also thought of it, then next, after the suspect is screened out, I plan to let you be in charge of the interrogation." ”

"Huh?" Qi Yuan was stunned for a moment and said, "This ...... It's not in order, right? ”
