Chapter 640: Evidence of Deviation

.

An expert is indeed an expert. Not long after Gao Facai arrived, new news came from the forensics department again and again.

First, 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 based on the growth cycle of the microorganism.

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

Immediately afterwards, heavyweight discoveries followed. Gao Facai actually detected the relevant time through the remains of the skull and a certain trace element in the preservative.

It turned out that the embalming agent and the head were dumped together in the metal box 5 to 7 years ago.

5 to 7 years ago, it happened to be the time when Tao Xiang stole the Tamil Star. He just happened to pour the head of the dead into the treasure chest at this time. What was his intention?

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

In this way, it can be proved that other gold and silver lacquerware should have been stored in that metal box. I don't know if those gold and silver lacquerware are Tao Xiang's treasures

Through these three discoveries, Zhao Yu and others have been able to roughly sort out a timeline:

About 10 years ago, Tao Xiang buried a metal box in Du Manting's grave. At that time, the metal box may have contained a lot of gold and silver treasures. Maybe, Tao Xiang is to pay homage to Du Manting, maybe 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 deceased!

So, that day 6 years ago seems to have become a critical moment. I don’t know what happened to make Tao Xiang do that.

Is it really related to Tamil Star?

Is it true that if we can solve this problem, we can find the whereabouts of the treasure and the Tamil star?

Gao Facai's efficiency was astonishing, and it was only ten minutes after lunch when he made a new discovery. Through the inspection of the six heads, he found that the embalming treatment methods of these heads and the composition of the embalming liquid soaked in the first place were different.

The older the skull, the embalming method and embalming liquid composition are very simple. But in the later period, the anti-corrosion techniques became more and more advanced and clever.

Although this discovery was shocking, for Zhao Yu, he was psychologically prepared.

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

After the case came out that year, the forensic doctors also discovered a rule, the more headless female corpses appeared in the future, the more sophisticated the embalming methods were.

Therefore, the police believe that the murderer was constantly trying and making progress throughout the whole process of committing the crime. In the process of disposing of the corpse, he was also looking for a better embalming method.

Especially when it came to Bai Lili later, the corpse was handled quite well.

The murderer opened a hole in the aorta of the groin of the corpse, drained the blood of the deceased with a professional instrument, and then injected a self-made liquid from the carotid artery. This liquid not only acts as if, but also brings the dead to life!

It is said that this technique is only known to professional morticians, especially the special antiseptic liquid, which is usually a family secret recipe and will not be easily passed on to the outside world.

Gao Facai's autopsy report pointed out that a hole was found in Bai Lili's head. He suspected that the murderer might have tried to extract Bai Lili's brain, and wanted to try some kind of head embalming experiment. Moreover, on some skin tissues, traces of some kind of antiseptic agent were also found.

From this, there are various indications that the murderer has put a lot of effort into the embalming of the corpse, and the murder is more like an experiment, which is obviously beyond the psychological scope of ordinary murderers.

"Oh!" Looking at the reports from the forensics department,

The members of the special investigation team who were enjoying their lunch no longer had the appetite to eat any more. Wu Xiumin frowned while reading the report, and said to everyone, "Why do I feel that this case is not that simple anymore? There are many places that seem reasonable, but it seems that they cannot be explained!"

"Is that so?" Ran Tao put down the 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 turned into a headless female corpse!" Wu Xiumin frowned, "But why didn't he just make Cui Fangyu Killed? Don’t you think it was Cui Fangyu’s betrayal that caused Du Manting’s death? Besides, not only did he not kill Cui Fangyu, but he also helped Cui Fangyu find his child. Isn’t that unreasonable?”

"It's easy to explain. Tao Xiang doesn't have that kind of function, so what if you kill Cui Fangyu?" Ran Tao patted his chest and said, "I see, everything was done by Tao Xiang secretly, and it was all his wishful thinking." , whether it's Du Manting or Cui Fangyu, I don't know!"

"Um...tsk tsk..." Wu Xiumin said again, "If the six women Tao Xiang killed were all for Du Manting, why did he wait so many years to bury Du Manting's head there instead of waiting for Du Manting to be buried there?" And, even after waiting for so many years, why didn't you just put the head in it, but put a lot of treasures first, and then tossed it back and forth? It really doesn't make sense! for what"

"You have never been married, you don't know!" Ran Tao began to tease Wu Xiumin again, "Do you think raising a child is easy? Tao Xiang raised Cui Lizhu, and it took time and money, so in order to raise the child , he dug up all the treasures and sold them.”

"I just said, don't interrupt when discussing the case in the future!" Wu Xiumin pouted, "Your greatest ability is to mislead the direction! Eat your lunch box and don't talk anymore! Please..."

tsk tsk...

Listening to the discussion of the team members, Zhao Yu also felt something strange. He also felt that there were indeed many strange things about Tao Xiang's affairs.

Moreover, Tao Xiang's personal situation is also quite different from many of his previous speculations.

For example, judging from the details of the murderer's handling of the headless female corpse, this person must be a delicate, gloomy, almost paranoid perfectionist!

However, apart from his delicate mind, Tao Xiang, the king of thieves, doesn't seem to fit these characteristics.

If Tao Xiang was really a perfectionist, then the head in the box shouldn't look like that. The box is so big, and there is plenty of space inside, he can put the head and the bottle containing the embalming solution in it!

Just like Li Dan in the hacking case, Li Dan is not a paranoid in the strict sense, and he still keeps the severed arms in good storage! So, as the murderer of the headless female corpse case, shouldn't he store it more carefully?

Tsk tsk... The more Zhao Yu thought about it, the more he felt that the evidence obtained today was a bit off.

Could it be... there are other secrets in this case

Is it Tao Xiang and his accomplices, or... Tao Xiang is not the real murderer at all!
