Chapter 642

Experts are experts. Not long after Gao Facai came, new news came from the assurance department.

Firstly, Gao Facai extracted a common soil microorganism from the surface of the metal box, and calculated the year when the metal box was buried in the soil through the growth cycle of the microorganism.

According to his calculation, Tao Xiang's metal box was buried there 10 to 13 years ago. Du Manting died 21 years ago. This discovery shows that Tao Xiang did not bury the box just after Du Manting was buried.

Then, heavyweight discoveries followed. Gao Facai detected the relevant time through some trace elements in the skull remains and preservatives.

It turned out that preservatives and heads were dumped in metal boxes five to seven years ago.

Five to seven years ago, it was the time when Tao Xiang stole the Tamil star. He happened to pour the head of the dead into the treasure chest at this time. What's his purpose?

Soon, Gao Facai led his team to use some chemical method to detect trace lacquerware and gold and silver powder from the scratches inside the metal box.

In this way, it can be proved that other gold, silver and lacquer ware should have been stored in that metal box. I wonder if those gold and silver lacquerware are the treasure of Tao Xiang?

Through these three discoveries, Zhao Yu and others can roughly sort out a time context:

About 10 years ago, Tao Xiang buried a metal box in Du Manting's grave. At that time, the metal box may contain many gold and silver treasures. Maybe Tao Xiang is to pay tribute to Du Manting, maybe it is because Tao Xiang needs a place to store treasures.

However, one day six years ago, Tao Xiang took the treasure out of the box and replaced it with the head of the dead!

So, the day six years ago seemed to be a key node. I don't know what happened that made Tao Xiang do that?

Is it really related to Tamil star?

If we can solve this problem, we can find the whereabouts of the treasure and the Tamil star?

Gao FA's efficiency was amazing. It was only ten minutes before noon that he made a new discovery. Through the examination of six heads, he found that the anti-corrosion treatment methods of these heads and the composition of the anti-corrosion solution soaked in the first time were different.

The older the skull, the simpler the anti-corrosion method and the composition of the anti-corrosion liquid. However, in the later stage, the anti-corrosion methods became more and more advanced and clever.

Although the discovery was shocking, Zhao Yu was prepared for it.

Because Gao Facai's discovery is very consistent with the autopsy report on the Headless Woman's corpse case.

After the case happened that year, the forensic doctors also found a law. The more headless female corpses appear in the future, the better their anti-corrosion means will be.

Therefore, the police believe that the murderer is constantly trying and making progress in the whole process of committing the crime. In the process of handling the corpse, he is also looking for better anti-corrosion methods.

Especially for Bai Lili, the body was handled quite well.

The killer opened a gap in the groin artery of the corpse, drained the blood of the deceased with a professional instrument, and then poured a self-made f antiseptic liquid into the carotid artery. This liquid can not only prevent corrosion, but also bring the dead to life!

It is said that this technique can only be understood by quite professional morticians, especially the special antiseptic liquid, which is generally a family secret recipe and will not be easily spread.

Gao Facai's autopsy report pointed out that a hole was also found in Bai Lili's head. He suspected that the killer might have tried to extract Bai Lili's brain to try some kind of head antiseptic test. Moreover, traces of some anti-corrosion agents were found on some skin tissues.

As a result, there are various signs that the murderer has made great efforts in the anti-corrosion treatment of the body. Killing is more like doing experiments, which obviously goes beyond the psychological scope of ordinary murderers.

"Oh!" Looking at a report from the assurance department, the members of the special investigation team who were having lunch no longer have the appetite to eat. Wu Xiumin frowned and said to the people, "how do I feel that this case is not so simple? Many places seem reasonable, but they don't seem to explain! "

"Really? For example? " Ran Tao put down his lunch box and asked curiously.

"Look... Tao Xiang likes that woman and won't let anyone bully Du Manting. Whoever dares to offend Du Manting will be made into a headless female corpse!" Wu Xiumin frowned, "but why didn't he just kill Cui Fangyu? Don't you think it was Cui Fangyu's betrayal that led to Du Manting's death? Besides, he not only didn't kill Cui Fangyu, but also helped Cui Fangyu find his children later. Isn't that unreasonable? "

"It's easy to explain. Tao Xiang doesn't have that function. What can you do if you kill Cui Fangyu?" Ran Tao patted his chest and said, "I see, all things are secretly done by Tao Xiang. They are all his wishful thinking. Neither Du Manting nor Cui Fangyu knows!"

"Well... Tut tut..." Wu Xiumin said, "if the six women killed by Tao Xiang were all for Du Manting, why would it take so many years to bury her head there before Du Manting was buried? Moreover, even after waiting for so many years, why not put the head directly in it, but put many treasures first, and then toss back and forth? It doesn't make sense! Treasures, heads, and so on. What is this for? "“ You haven't been married, you don't know! " Ran Tao began to tease Wu Xiumin again. "Do you think it's easy to raise a child? Tao Xiang needs time and money to raise Cui Lizhu, so in order to raise his children, he dug up and sold all the treasures? "“ I said, "don't interrupt when we discuss the case in the future!" Wu Xiumin pouted, "your greatest skill is to mislead the direction! Eat your lunch box and don't talk! Please... "Tut tut... Zhao Yu felt a little different after listening to the comments of the team members. He also felt that there were many strange things about Tao Xiang. Moreover, Tao Xiang's personal situation is also very different from many of his previous speculations. For example, from the details of the murderer's handling of the headless female corpse, this person must be a perfectionist with delicate mind, gloomy psychology and almost paranoid! However, in addition to his delicate mind, Tao Xiang, the thief king, does not seem to meet these characteristics. If Tao Xiang is really a perfectionist, the head in the box should not be like that. The box is so big that there is plenty of space inside. He can put his head together with the bottle containing antiseptic liquid! Like Li Dan in the original hand chopping case, Li Dan is not a paranoid in the strict sense. He keeps his cut arms well! So as the murderer of the headless female corpse case, shouldn't he store it more carefully? Tut tut... The more Zhao Yu pondered, the more he felt that the evidence obtained today was somewhat biased. Is there any other secret in this case? Is Tao Xiang and his accomplices, or... Tao Xiang is not the real murderer at all!? This novel has been translated by www.novelhall.com and if you are reading this somewhere, they have stolen our translation.
