"Ziliang? Are you Ziliang? ”

Zhang Yang was a little surprised, but he didn't expect the other party to be Ziliang. It stands to reason that Zhang Yang and Ziliang still have a relationship, when the two graduated with a master's degree, they worshiped the same teacher, and they were classmates, this Ziliang is indeed a genius boy, with an IQ of up to one hundred and eighteen, and Zhang Yang is ashamed of himself!

Later, Ziliang had something at home, so he stopped his studies halfway and did not continue to study with the teacher, saying that he wanted to go home to inherit the family business, and the two had less time to contact.

It's really not good to study, only to go home to inherit the family business, but I didn't expect Ziliang to be a policeman now, and helped the Macheng Police Department crack several big cases, the two chose differently, but I didn't expect that in the end, they would end up in the same place!

"Long time no see!" Ziliang looked at Zhang Yang and smiled, he didn't expect to meet an acquaintance here!

"Didn't you go home and inherit the family business?"

Hearing this, Ziliang shook his head helplessly: "The family is already stable, and the company at home is being taken care of, so just do what you like to do!" ”

Gao Jian on the side heard this and said: "It's good that you know each other, Ziliang joins the Investigation Department, you investigate together, and strive to solve the case as soon as possible!" ”

Then a brief introduction, even if Ziliang is handed over, he will officially join the reconnaissance department of the Jiangzhou Police Department!

"Hello, Huang Feifeng! The leader of the reconnaissance team! ”

"Ziliang, take care of me!"

Then Huang Feifeng arranged the tasks of both sides, divided into several groups, Ziliang and Zhang Yang in a group, and others in a group, going out to collect evidence!

Zhang Yang and Ziliang drove to visit Jiangzhou Experimental Middle School.

"This is the autopsy report, except for the latest victim who died of cyanide, the other victims died at their own hands, and the murderer at the scene left the victim with a glimmer of life, what do you think?"

"Judgment, punishment!" Ziliang thought for a moment and groaned.

Zhang Yang continued: "The time of death of the victim was in the early hours of the morning, but the female victim was not, obviously the female victim committed suicide, but why did the murderer return to the scene and leave footprints!" ”

"The killer and the victim knew each other, and he left the footprints on purpose, and he was hinting at the police." Ziliang Dao.

"Well, murderers have motives for killing, whether they are normal or abnormal, they have their own set of logic, so why did he do it!" Zhang Yangdao.

"This murderer has a story to tell! Is there any other information? Ziliang frowned, there are too few clues to collect!

Hearing this, Zhang Yang thought for a while: "The murderer's DNA is Li Qing, and he was also a teacher in Jiangzhou Experimental Middle School!" What's going on here......"

The two came to Jiangzhou Experimental Middle School, and during the visit, they learned about a person named Qin Yu, who was the best friend who played with Li Qing at the beginning, and is still teaching in the school!

Seeing Zhang Yang and the others coming to him, Qin Yu subconsciously frowned, and this action also made the two of them feel in their hearts: there is a play!

When they first met Qin Yu, Zhang Yang and Ziliang also had a general impression, as the chemistry teacher of Jiangzhou Experimental Middle School, he was meticulous, and his whole face was majestic!

Hearing Li Qing's words, Qin Yu couldn't help but sigh: "I still don't believe that he would do such a thing, I met him once some time ago, and it's still normal!" ”

"When did you meet him?" Zhang Yang asked.

"On January 7th, around ten o'clock in the morning, I didn't have classes at that time, and we met." Qin Yudao.

"Did you talk about anything?" Ziliang asked.

"It's mainly about the development and changes of the school, as well as his original case, and I still don't believe that he killed someone......" Qin Yu was a little gloomy when he said this, and his expression was indescribable.

"The results of the forensic test in the police department came out, showing that the hallucinogen ethanol in the victim's body 🈶️ and cyanide in Wang Qiu's body." Zhang Yang stared at Qin Yu and said, "Do you know where he got these things from?" ”

"Ethanol, cyanide......" Qin Yu lowered his head and muttered.

"Yes, you're a chemistry teacher, you should know how to get these things!" Ziliang Dao.

"The chemical purchases in our school are all recorded and purchased uniformly! It is difficult for ordinary people to buy these on the market, unless they prepare ...... by themselves" Qin Yu seemed to think of something, and said very cautiously, "If Li Qing will kill Wang Qiu, I don't believe it first, he went to prison for Wang Qiu in the first place!" Then he turned his head to look at the two of them: "I hope you can investigate it well!" ”

For his only best friend, he couldn't do anything when he was framed in prison, and now he was framed as a killer, he said he didn't believe anything!

Qin Yu kept holding his forehead, looking indescribably annoyed!

Then the two of them asked Qin Yu for general information, because Qin Yu still had to have classes with students later, so they didn't disturb him, so they temporarily suspended the inquiry......

"What do you think?" Zhang Yangdao.

"He's telling the truth!" Ziliang nodded, as a policeman, he has been dealing with people for a long time, and he can still tell whether the other party is lying from his micro-expressions!

When Qin Yu went to class, Zhang Yang and the others also went to the chemical warehouse of Jiangzhou Experimental Middle School to search, and they found that in January, there were indeed some items in the school's warehouse that were missing and the amount of use was a little large, but there was no disappearance of chemicals!

"Isn't this a lot of chemicals?" Zhang Yang asked!

"What's the ...... Now children don't know how to cherish it, and there are more things wasted in chemistry class, which is less! The porter glanced at the two of them!

Zhang Yang glanced at Ziliang next to him, and Ziliang also shook his head: "It's not a raw material for making ethanol or cyanide!" ”

When the two were chatting, Zhang Yang learned that Ziliang later crossed over to work as a chemistry teacher for a period of time, according to what he meant, this was for the preparation of the cloud police later!

Next, the two of them visited the school and inquired, but they didn't find any other abnormalities, so they could only wait for Qin Yu to understand the relevant information!

"Do you think this Qin Yu is possible?" Zhang Yang asked.

Ziliang thought for a moment, then shook his head and said, "It should be unlikely, there is no motivation, and he was in class at that time, and there is an alibi!" ”

After a while, Qin Yu came back from class, but his face was a little not good, obviously angry with the students......

"Shall we continue?" Zhang Yang asked.

Qin Yu took a deep breath and said, "Yes, what do you want to know?" ”

"We want to know, why was Li Qing framed in prison in the first place, can we talk about it?"

Hearing this, Qin Yu was obviously stunned for a moment, he didn't expect Zhang Yang to ask about it, but then he nodded: "He was wronged, everyone didn't believe him at that time, even his lover Wang Qiu didn't believe him!" ”

"Why?"
