After ten minutes, Lao Zhao and others returned to the criminal police team.
In the office, the people doing the trace examination and even the forensic room were not there.
¡°Old Zhao¡¯s sharp eyes had long seen the whiteboard over there, so he went straight over without any further delay.
Of course, Guo Yishuo and others also 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?"
He asked.
"Sister Su and Xiao Bai returned to the autopsy room, saying they wanted to see if they could find any more evidence.
Brother Cui went out and said he would be back soon. "
Since there is suspicion, it must be investigated clearly.
Cui Xingran went to find an old classmate who was engaged in this field, trying to find out where the drugs extracted from the victims returned to the country from.
However, the final result was not good.
Because, that medicine doesn¡¯t even exist on the black market abroad.
Only a very small number of people have heard any news about this medicine.
But everyone still doesn¡¯t know much about the specific information and ingredients of the drug.
To put it simply, it is actually an enhanced version of chloral hydrate!
Ordinary chloral hydrate is generally used clinically as a sedative, hypnotic, and anticonvulsant drug.
Chloral hydrate has a mild hypnotic effect, its mechanism of action is similar to that of phenobarbital drugs, and it can induce quasi-physiological sleep;
When the dose is too large, chloral hydrate can cause acute poisoning, inhibit myocardial contractility, inhibit the medullary respiratory center and vasomotor center, which can be life-threatening.
And one of the three victims had similar drug residues detected in the gastric lysate in his body.
It is more effective and evaporates faster!
Anyway, that day started from everyone noticing something was wrong and calling the police, to the police arriving at the scene, and finally the autopsy.
The first autopsies of the two victims found nothing in their bodies.
¡°As for the last victim who was dissected after nearly twenty hours, the residual drug extracted was minimal.
Fortunately, the Municipal Bureau¡¯s Trace Inspection Office has strong professional skills!
Even the smallest trace of residual components has been detected.
Of course, a forensic doctor who can find something like this from a corpse is even more powerful!
How careful do you have to be to find out?
Lao Zhao went directly to the trace inspection office to wait.
Cui Xingran came back not long after, mainly because he had been in the laboratory for several days and his mind was confused. He had to go out for a walk. So he went to his old classmate to ask about the situation.
"Brother Zhao? Are you waiting for me?"
"Well, please tell me what's going on."
Although it is clearly written on the whiteboard, is it as good as a real person telling it?
There are many details that cannot be written down.
Cui Xingran sat down and slowly talked about the clues that were now clear.
Lao Zhao nodded from time to time as he listened:
¡°Is the victim the murderer?¡±
"right."
"You can find these clues in the surveillance video of the swimming pool that day, that is, you have to slow down and look at it."
Otherwise, it is easy to ignore the picture of less than two seconds.
Didn¡¯t all the policemen in the criminal police team, from Lao Zhao to the police in the office, find out?
"what happened?"
"We have always believed that Chen Kai and Zhou Liheng met misfortune because they went to rescue Xu Song after discovering something was wrong."
The scene of the crime at the time, as well as the actual situation learned from the oral accounts of witnesses, are all developing in this direction. (Remember the website address: www.hlnovel.com
