Liu Huiqin died, she was the junior high school class teacher of the murderer in this case, and the murderer knew that she was severely allergic to pollen, so he used this unique method of absolute targeted killing.

It is precisely because they are teachers and students that Liu Huiqin is defenseless against the deceased and accepts the other party's gift calmly.

It was Liu Huiqin's husband who called the police, he had just come back from fishing, and when he opened the door and entered the house, he found Liu Huiqin sitting on the ground motionless, so he hurriedly called the police.

A large amount of pollen was found on the ground at the scene and the cause of death has been determined, although further time is needed to corroborate evidence to ensure that there are no other suspected causes of death.

The technical team conducted a careful fingerprint and footprint search at the scene, and after comparison, there was no one else except Liu Huiqin and her husband's.

Even the colleagues of the trace examination department only found Liu Huiqin's fingerprints on the blue perfume gift box, and did not find any traces of the suspected murderer.

The murderer gave Liu Huiqin a gift, but he didn't leave fingerprints?

This shows that the murderer was wearing gloves at the time, but he was wearing gloves to give gifts, and he would not be noticed by Liu Huiqin? And Liu Huiqin also knew about the death of Du Tan and Xu Kuan, and he would definitely take precautions.

This shows that Liu Huiqin has absolute trust in the murderer, and will never believe that he is the murderer.

It must have been like this—

The murderer came to Liu Huiqin's door, knocked on the door, and saw Liu Huiqin. Liu Huiqin did not attend the class reunion this time, so she was very excited, Liu Huiqin invited the murderer into the house to sit down, but the murderer politely refused.

The murderer wore gloves, because it was already autumn and the weather was hot and cold, and bringing a pair of gloves would not arouse suspicion.

Moreover, Liu Huiqin never thought that the student in front of her, who was close to her, would harm herself.

The murderer used the reason that Liu Huiqin did not attend the class reunion to visit the teacher with gifts, but said that he was in a hurry, so he had a brief conversation with Liu Huiqin at the door and left.

After the killer left, he opened the perfume gift box, resulting in pollen allergies, leading to death.

"Then the question is, among these twenty-eight people, who will never be suspected by Liu Huiqin?" I thought about it in my head and muttered.

"Now Yao Xun'an can completely clear his suspicions, because he has no time to commit the crime at all, and the criminal police team has sent people to monitor him 24 hours a day." Li Meng muttered.

At this moment, Officer Wang suddenly walked into the office of the Serious Crime Team and said to me: "Team Qin, just sent a message from the traffic management department that Yao Xunan returned the ticket to leave the day after tomorrow and bought a new train ticket for tonight, and he is ready to leave overnight." ”

I pondered for a moment and nodded, indicating that I knew, but I didn't say anything.

Officer Wang continued to ask me, "Will you let him go?" He's the murderer's next target. ”

I paused and replied, "He has been cleared of suspicion, and we have no right to restrict his personal freedom, since he is leaving, let him go." Now that the murderer has just committed a crime in this city, he must still be in this city, and maybe his departure is the safest. ”

……

A few hours later, night fell, and the city of Ningzhou was once again shrouded in darkness.

Our hearts are as dark as the sky.

After a long period of investigation and visits, the Serious Crime Team and the Criminal Police Team finally conducted an investigation of all 28 people who attended the class reunion.

There were a total of eight people wearing size forty-two shoes, and in addition to Yao Xun'an and Chu Ming, there were six others.

An hour had passed since the end of work, and everyone was still sitting in the office, doing a tense analysis of the case.

Due to the death of teacher Liu Huiqin, we have to rethink the murderer's motive for killing, in addition to the revenge of the "Seven Dragons and One Phoenix" school bullying gang, we also have to investigate what unknown things happened to Liu Huiqin.

"What can now be confirmed is that Liu Huiqin was still defenseless against the murderer even when she learned that Du Qin and Xu Kuan were killed." I spoke first.

When I visited and investigated Liu Huiqin, I went alone, and only I knew about Liu Huiqin's situation.

I gently closed my eyes and pressed my index finger to my temple to carefully recall the conversation between Liu Huiqin and me.

I don't know why, the name Chu Ming has been appearing in front of my eyes.

Because when talking to Liu Huiqin, Liu Huiqin said many times that this child named Chu Ming is honest and cowardly, even if he has conflicts with the "Seven Dragons and One Phoenix" campus bullying gang, he will never do such a thing as murder.

Therefore, Chu Ming will never arouse Liu Huiqin's vigilance, but what is his motive for killing Liu Huiqin?

According to Liu Huiqin's confession, when Chu Ming was bullied and asked Liu Huiqin to complain, Liu Huiqi actively coordinated from it, criticizing and bullying Chu Ming's classmates while comforting Chu Ming.

It is precisely because of Liu Huiqin's active efforts that four members of this eight-member gang no longer participate in school bullying.

So Chu Ming should be grateful to Liu Huiqin, how could he choose to kill someone?

"Team Qin, did you think of something?"

Seeing that I hadn't spoken, Lin Zifan suddenly asked me.

That's when I came to my senses and told them what I thought.

Everyone is a veteran criminal policeman, and they have also dealt with all kinds of random and indiscriminate homicide cases, and they know that sometimes, the murderer wants to kill a person, and he doesn't need a reason at all.

Everyone also knows that a person's appearance alone is not enough to judge a person's heart.

Maybe Chu Ming is exactly what everyone fears, under a harmless skin of humans and animals, there is a sinister and ugly heart.

Four people have died so far, and the police must speed up their pace.

I decided to summon Chu Ming overnight and interrogate him using a polygraph device.

No matter what aspect you think about, Chu Ming is suspected of committing a major crime.

Not only because of this, but also because he was the only one of the eight remaining eight people who wore size 42 shoes who was bullied by the "Seven Dragons and One Phoenix" school bullying gang that year.

And coincidentally, he was also the worst bullied in the school bullying incident that year.

At the same time, Liu Huiqin's autopsy results also came out.

She did die of a lung infection caused by a severe pollen allergy.

The criminal police team summoned Chu Ming, and the serious crime team is simultaneously reporting the case and applying for a search warrant and arrest warrant for Chu Ming.

We want to conduct a thorough investigation of Chu Ming.

Chu Ming was timid, and after receiving a summons from the public security organs, he immediately came to the criminal police team of the Ningzhou Public Security Bureau......
