Everyone in the city bureau knew that Yang Xiao was still investigating Liu Qing's murder case.
Some people say Yang Xiao is stupid.
The murderer has been caught, so why bother?
So what if we find out the secret?
It can't change the fact that Liu Qing killed someone.
On the contrary, it may offend city leaders.
Therefore, when Liang Zhiqiang came in, Yang Xiao did not put away the case files in front of him.
Liang Zhiqiang saw the case file on Liu Qing's case, took out a document and an evidence bag from his back, handed it to Yang Xiao, and said: ?.?????.ℂ??
"I know you didn't give up!
Let me show you something fun. "
"What?" Yang Xiao took the evidence bag from Liang Zhiqiang's hand and held it up to his eyes for inspection.
There were two things in the evidence bag.
A black box.
Only the size of a cigarette box.
No labels, no connectors, perfectly sealed.
Yang Xiao couldn't recognize what it was.
The other one is easy to recognize, it looks like a key switch similar to a wireless car key.
Liang Zhiqiang turned around with a mysterious look on his face, closed the door of Yang Xiao's office, then stretched out his finger and pressed a button on the wireless switch.
Bah!
The black box suddenly let out a sharp chirp.
It's not loud, but it's very harsh.
The chirping sound seemed to come from a black box, but the sound was so erratic and distracting that it was impossible to tell the exact location of the sound.
When it's close, it's in your ear.
When it is far away, it seems like it is on the horizon.
Very uncomfortable.
Liang Zhiqiang pressed another button, and the sharp low sound finally disappeared.
In just half a minute, Yang Xiao felt that his ears were finally clear.
Yang Xiao picked up the evidence bag and tried to press other buttons through the transparent bag. The harsh sound reappeared. The buttons could even adjust the volume and frequency of the sound. When the frequency reached a certain value, Yang Xiao's ears could not hear it. Such a harsh noise.
"Director Liang, where did you get such a thing?" Yang Xiao put the evidence bag on the table, stretched out his little finger and picked out his ears twice.
It’s so uncomfortable!
No one can stand the pollution of this kind of high-frequency noise.
Liang Zhiqiang did not answer Yang Xiao immediately and said:
“I looked it up and it’s called a UHF transmitter.
Some people abroad use it to drive away wolves in the wild.
This player can emit ultra-high frequency sounds of up to 50,000 Hz.
Our human ears can hear sounds at frequencies up to 20,000 Hz, and wolves can hear sounds at frequencies up to 80,000 Hz.
It can emit sound at frequencies far beyond what we humans can hear! "
"Director Liang, this is not the school's science and technology classroom, so don't show off!" Yang Xiao interrupted Liang Zhiqiang's talk.
"Do you know where you found this thing?" Liang Zhiqiang smiled mysteriously and said immediately before Yang Xiao could speak:
"In Long Yaping's suitcase!"
"This is Long Yaping's thing!" Yang Xiao stood up from the chair.
"That's right!"
Liang Zhiqiang nodded and said:
"We found it in the suitcase that Liang Zhiqiang was going to take abroad!"
Why does Long Yaping carry such a thing with him?
Its purpose is obviously not to drive away wolves!
Yang Xiao's eyes fell on Liu Qing's medical record, which had the words "severe tinnitus" and "auditory hallucinations" written on it.
Could it be...
A possibility emerged in Yang Xiao's mind.
No way!
However, it is not surprising for the criminal police to encounter seemingly impossible things during the investigation of the case. An idea flashed in Yang Xiao's mind.
If that were the case, that would be unbelievable!
Everyone was played around by him.
At this moment, Liang Zhiqiang placed the second thing he brought in front of Yang Xiao and said:
"Xiao Yang, yesterday you asked me to take hair for DNA comparison.
This is the identification result.
I think it's quite interesting, maybe it will help you solve the case. "
Yang Xiao brought his thoughts back to reality and his eyes fell on the identification report. It clearly stated that the DNA of the hair was consistent with that of corpse No. 1. These hairs came from Hu Xiaomin!
Hu Xiaomin once appeared in Long Yaping's trunk!
Long Yaping is lying!
Hu Xiaomin had indeed been to Bo Cui Villa, but she didn't walk in by herself, but was put in the trunk and taken in!
Yang Xiao left his desk, opened the office door and rushed out, shouting:
"Qu Da, inform Wen Zhi that there are new discoveries in Liu Qing's case, please do not recommend him to the procuratorate for the time being!
I'm going to the provincial capital, and I'll talk about anything else when I get back. "
Everyone in the Sixth Brigade raised their heads and watched with surprise as Yang Xiao rushed out of the office.
…
Chengdu, Xichuan University Hospital.
This is a national tertiary hospital.
Among them, the Department of Psychiatry ranks among the top three in the country.
It is an authoritative hospital for mental illnesses in western China.
It is also a forensic center for mental illness.
Li Li's senior sister named Gao Yuezhu is a chief psychiatrist and graduate tutor.
A well-known mental illness expert in Xichuan Province.
Yang Xiao drove back to Chengdu from Mingzhou just to visit this great expert.
Gao Yue is in her thirties, wears a pair of golden glasses, and carries an elegant and dignified temperament.
She was sizing up Yang as she spoke.
