Chapter 588 Dig Deep
There are many ways to infer age through forensic science. To sum it up... Someone wrote a book with hundreds of pages.

Basically, everything from teeth to phalanges to pubic bones to six major joints to DNA and mitochondria has a way of age inference.

For living bodies, all imaging solutions can be used to identify age, including X-ray, CT, MRI, ultrasound and so on.

However, different schemes and locations have different errors.

It is not easy to approve within two months.

"The hospital or the Health Bureau has a solid foundation. I remember helping people to reissue the birth certificate." Shen Yaowei listened beside him, and said leisurely.

Meng Chengbiao couldn't help but glanced at Shen Yaowei, and said with a smile, "Yaowei is a man who can help people. However, the files from 20 years ago must be checked carefully."

"Then look for it. Can Yaowei do it?" Jiang Yuan ordered Shen Yaowei.

Shen Yaowei responded, took out his mobile phone and said, "I'll call and ask someone first."

Beside, Wu Junhao said: "I think we can search the residences of Zhang Xiulan and the others again. Birth certificates are still very important, so they may not necessarily be thrown away. When we arrested them, they probably didn't think of this."

"Okay, you lead the team to look for it." Jiang Yuan also agreed.

Meng Chengbiao coughed twice and said, "I have another idea."

"Oh, Team Meng, tell me." Jiang Yuan put his hands on the table and looked at Meng Chengbiao.

"This Zhang Haobin, I checked his file. In the past few years alone, he has frequently been in and out of the police station because of fights. However, the Zhang family has money in their hands, so they usually pay more aggressively for compensation, and the consequences are not serious. ..."

When Meng Chengbiao said this, he paused for a moment, coughed and coughed twice, and said, "What Team Wu said just now made me suddenly think that Zhang's family may have falsified their birth certificates. Are there cases of falsification in these cases?"

Jiang Yuan asked: "For example?"

"Look for someone to take the blame? Or if you hurt someone, turn around and run away, the victim may not know him, so you can't find anyone..." Meng Chengbiao looked at Jiang Yuan, then at Tang Xiaobo, the director of the director who had been silent all this time, seeing the two No one showed the expression of the scheme, and then continued:
"Zhang Enfan's evaluation of his nephew Zhang Haobin is rude and lustful. I thought, he doesn't know about Jiao Lina's case. If his evaluation doesn't include Jiao Lina's case, how will it be reflected? Zhang Enfan's evaluation of his nephew is always unreasonable. He can pick cakes on the ground. There is no need for this, he can just say it, right?"

Jiang Yuan and the others fell into deep thought.

Jiang Yuan nodded secretly.If it weren't for the old detectives who were suspicious by nature, it should be no problem to add suspicious LV1.5 to Meng Chengbiao's words.

Jiang Yuan asked: "Do you think he did other cases?"

"He has already done a lot of cases." Meng Chengbiao got into the mood at the moment, and he was not too polite, and said straightforwardly: "Now, one is to see if he has the opportunity to make a big case. I think it is very possible. Not only Zhang Enfan's evaluation, but also his personality, a young man who likes to solve problems violently and has tried rape and murder, would he commit similar crimes?"

The criminal police present nodded slightly.

As the saying goes, "the prodigal son turns his head back and does not change his gold." In ordinary domestic gold mines, the gold content per ton of ore is only 2g, which is difficult for ordinary criminal police to see.

The most common violent offenders you see are habitual offenders, just like a man with domestic violence, not just one domestic violence, only those violent offenders who have served a long sentence can change.However, the reason for their change is probably not a change in concept, but a change in their behavior and habits after serving a long time in prison. In addition, as they grow older, the secretion of testosterone and other hormones in the body decreases, which will also lead to become less violent.

And rapists are very easy to become habitual offenders.

The act of rape is itself a sign of less control than desire, which keeps coming.

If the first crime is not punished, it is not incomprehensible to commit a second crime and a third crime when the desire is high.

"How do you want to investigate?" Jiang Yuan felt that Meng Chengbiao's theory was fine, but the reality and from which angle to investigate were the real problems before him.

The first thing Meng Chengbiao thought of was interrogation, and he said, "I think you can ask Zhang Enfan, he might know something. Another thing, maybe you can cheat the Zhang family?"

Wang Chuanxing said: "The ordinary Zhang family probably doesn't know anything. If Zhang Xiulan's family is concerned, they probably won't confess their grandson or son."

Meng Chengbiao had to admit that this was indeed a concern.

It is so difficult for Zhang Xiulan and others to confess Zhang Enfan, but it is even more difficult to confess their direct descendants.

"However..." Meng Chengbiao was a little reconciled, and said, "Zhang Xiulan's family handles the corpse very well. They know when the corpse is stiff, they know how to clean the corpse, and they also know how to rot more easily and how long to keep it..."

"It is indeed bolder than ordinary people." Jiang Yuan nodded.

Mu Zhiyang said: "There are old people who know how to wear shrouds in the village. Zhang Xiulan is not young, so she should have helped them all."

"It's also a reason." Jiang Yuan was doing nothing.

From his point of view, there is nothing wrong with the inferences of several people, and there are reasons for overthrowing them.

In general, further investigation is required.

But there is one thing to say, this case has progressed to the current level, and it is more appropriate to complete the investigation.

It is obviously a waste of resources simply to pursue severe punishment... However, digging deeper around a person or a series of events is itself one of the ways to solve a case.

Thinking of this, Jiang Yuan patted the table lightly twice, and said: "Meng Meng, you continue the interrogation according to your ideas. Wang Chuanxing, you have reported the injury cases and sexual assault cases in the past two or three years, not only in Litang Township, but also in the surrounding areas. Look up all the places in the four miles and eight villages, and show them to me later, the number should not be much."

After thinking for a while, Jiang Yuan said again: "Turn through the disappearance case carefully, and sort it out later."

Litang Township is also in Ningtai County, which also means that Jiang Yuan has screened all serious and serious cases in the area.

However, Jiang Yuan originally screened cases within the scope of the entire county, and some minor injuries that may not meet the standard of serious cases, or simple obscenity cases, or cases outside the county, were outside the scope.

In addition, if a woman like Jiao Lina has no relatives and no reason, and no one really looks for her after she disappears, the police will have no way of knowing.

After a few people agreed, they went to work.

Although there were objections from each other, everyone was in the same mind when it came to putting the villains to death.

Jiang Yuan himself planned to wait until the Zhang family's case was over before continuing to work on small cases. At this time, he did not change his original intention and continued to work.

He didn't look for cases with little evidence, but cases where a lot of evidence was collected but not processed further.

Especially minor injuries and obscene cases.

In Jiang Yuan's impression, cases of minor injuries are not difficult to investigate.Generally speaking, such cases are due to various reasons, the two sides fight each other.If no one is injured, it is a typical public security case. The adjustment, apology, and compensation are up to 15 days of detention.

If someone is injured, whoever is seriously injured will be justified. Minor injuries will be jailed for several months, and serious injuries will be jailed for several years.

In a place like a county town, both parties to the fight probably knew each other, or they would know which side they belonged to after a little inquiry, and the difficulty of handling it was not in the investigation.

Those who run away and can't find anyone are more talkative.

Jiang Yuan focused on such cases, and used the same method as before, first remembering the fingerprints, footprints and other information of the Zhang family, and then directly comparing the photos in the case.

It didn't take a day, and Jiang Yuan really got involved in an obscenity case, or, it can be called an attempted rape case!
Zhang Haobin's fingerprints appeared on the backpack carried by the victim, but because the comparison was slightly more difficult, it was never matched.

Of course, one obscenity case was not enough. Just when Jiang Yuan was thinking about whether to make persistent efforts or to find another way, Meng Chengbiao returned again, carrying "Zhang Enfan's Curse" with him.

"This guy is now asking for meritorious service." Meng Chengbiao said with a smile, and then his expression became serious: "He said that Zhang Haobin had several girlfriends, and one of them disappeared."
