Chapter 467: If in doubt, investigate thoroughly.

So why don't you have been busy for so many days?

"Alright, alright, hurry up and drive."

"Oh."

......

After more than ten minutes, Lao Zhao and the others returned to the criminal police team.

In the office, the people who did the trace examination and the forensic room were not there.

Lao Zhao had already seen the whiteboard over there with his sharp eyes, and he passed by without delay.

Of course, Guo Yishuo stepped forward and carefully looked at the clue points and case analysis on the whiteboard.

The steps are very clear and can be understood at a glance.

"where are they?"

asked.

"Sister Su and Xiaobai returned to the autopsy room and said they wanted to re-see if they could find any more evidence.

Brother Cui went out and said he would be back in a while. "

Since there is doubt, it is necessary to investigate clearly.

Cui Xingran went to an old classmate who was working in this area, trying to find out where the drugs extracted from the victim's body came from exile and returned to China?

However, the final result was not good.

Because that medicine is not even available in the foreign black market.

Only very few people have heard some news about this medicine.

But for the various specific information and ingredients of the drug, everyone is not very clear.

To put it simply, it is actually an enhanced version of chloral hydrate!

Common chloral hydrate is clinically used as a sedative, hypnotic, and anticonvulsant drug.

Chloral hydrate has a mild hypnotic effect, and its mechanism of action is similar to that of phenobarbiturates, which can cause quasi-physiological sleep;

When the dose is too large, chloral hydrate can cause acute poisoning, inhibit myocardial contractility, inhibit medulla oblongata respiratory center and vascular motor center, and can be life-threatening.

In one of the three victims, the drug residue detected in the stomach lysate was similar to this drug.

The effect is stronger and the volatilization speed is faster!

Anyway, that day, everyone found something wrong and called the police, until the police arrived at the scene, and finally there was an autopsy.

The two victims who were first autopsied found nothing inside.

And the last victim who was dissected after nearly 20 hours, the residual drug extracted is also very small.

Fortunately, the professional skills of the trace inspection office of the Municipal Bureau can be strong!

Even a tiny amount of residual components were detected.

Of course, a forensic doctor who can find such a thing from a corpse is even more powerful!

How careful is it to find out?

Lao Zhao went directly to the trace inspection office to wait.

It didn't take long for Cui Xingran to come back, mainly because he had been in the laboratory for several days in a row, and his mind was clouded.

"Brother Zhao? Wait for me?"

"Well, tell me what's going on."

Although it is clearly written on the whiteboard, is it comparable to a real person telling it?

There are many details that cannot be written.

Cui Xingran sat down and slowly talked about the clues that were now clear.

Lao Zhao nodded from time to time as he listened:

"The victim is the murderer?"

"right."

"In the surveillance video of the swimming pool that day, you can find these clues, that is, you have to slow down and look at it."

Otherwise, it would be easy for people to ignore the picture that was worth less than two seconds.

In the criminal police team, from Lao Zhao to the office, didn't they all find it?

"what happened?"

"We always thought that Chen Kai and Zhou Liheng suffered misfortune because they went to rescue Xu Song after they found something wrong."

The crime scene at that time, and what happened at the time from the witnesses' oral accounts, all developed in this direction.
