I got the wrong blind date, and I became a detective

Chapter 106

The task force headed by Gong Lao was stationed at the Provincial Medical University on the same day.

Zhang Yang is naturally also in it.

The investigation of the task force naturally began with a comprehensive inspection of the back kitchen of the second canteen, and found that there was arsenic not only in the dough mixer, but also in the flour and rice that had not been used up.

First of all, they checked the supply units of the canteen, but only found some problems in the accounting, but did not find any problems in the other goods.

This means that the flour and rice were poisoned after they were transported to the school, but there was no monitoring in the back kitchen, which did not provide any useful information.

After two days of investigation, the cooks who had access to flour and rice did not have any motive or indication of committing the crime.

And in the whole city, for more than a year, all the records that can buy arsenic have been checked, and all the drug units, time of purchase and use of drugs have been checked, and no problems have been found.

All the ideas are at an impasse.

Gong Lao called the people from the task force and held a meeting together to study ideas.

"Old Gong, I have re-sorted out my thoughts, and I still think that there is the greatest possibility of deliberate revenge among classmates.

"The most important thing is motivation.

"But what I don't understand is why such a wide range of methods are used, can it be said that the murderer may still have a grudge against everyone?"

Zhang Yang said with a frown.

"That's not right, according to you, if you really want to poison such a large area, wouldn't it be easier to put it in the school cistern?"

asked a police officer.

"Arsenic is a lens, it is not completely soluble in water, and the color of dissolved in water will change, and the students here are all medical students, so it is inevitable that people will be noticed.

Zhang Yang said on the side.

"How do you know?" The

policeman was very curious, even he didn't know these things, and this Zhang Yang in front of him knew so well.

Even if you're a detective, you can't be all-encompassing, right?"

"Forehead......"

"Empathy, and ...... I looked it up on the Internet.

Zhang Yang said slowly.

"Okay!"

"Let's continue according to Zhang Yang's idea, the next step is to investigate some in the student group, or let them provide clues.

"After all, they might know something.

Gong Lao said on the side.

"Well......

" "No, perhaps, I know who the murderer is......"

Just as everyone was silent, Zhang Yang suddenly stood up with his mobile phone.

"Who?!"

Gong Lao hurriedly asked.

Everyone raised their heads in unison.

"Clinical Medicine, Second Year Class 3, Wang Lu.

Zhang Yang shook his phone.

......

An hour later.

The female student, Wang Lu, was taken to the interrogation room of the Provincial Public Security Department.

At the same time, in her locker, she found latex gloves, pesticides, concentrated sulfuric acid, sawtooth and many other things.

After inspection, there was still arsenic powder on Wang Lu's latex gloves.

It can almost be concluded that this female college student named Wang Lu is the murderer of this extraordinarily large poisoning case.

But everyone looked at this beautiful female college student in the interrogation room in disbelief.

Although the figure is not high, it is well developed, uneven, and has a good face, coupled with the smooth long hair casually draped over the shoulders, no one would have thought that such a young and beautiful girl would do such a heinous behavior.

"Zhang Yang, how did you find out the murderer

?" "And you can even accurately tell her major and class?" Gong

Lao asked in surprise.

"I went to the post bar of the Provincial Medical University and posted an anonymous post about the collection of clues about the poisoning case, but there were many people in it talking nonsense and all kinds of speculations. "

But I found a reply from a person in it that raised my suspicions. She

didn't say anything directly, but only said that one of her roommates didn't go to the cafeteria to eat at noon that day, and when she asked her to eat, she still pulled and didn't let herself go.

She posted the message anonymously.

"And I talked to her privately, asking for the name and class.

Zhang Yang explained to Gong Lao.

"Can you judge it based on this?" Gong

Lao was very puzzled, this is too child's play, although this person is also possible, but there is no basis.

"Of course not, I used this person's name and found a notice on their school's official website.

Zhang Yang handed the phone to Gong Lao.

Gong Lao took it and took a look.

It's a notice about a major demerit.

A sophomore girl named Wang Lu was given a major demerit for seducing a school teacher and having an improper relationship that caused a bad impact.

"This ......

" "Motive for the crime?"

Gong Lao was shocked.

I have been thinking about it before, saying that I want to keep pace with the times, why didn't I think about using the means of the Internet?

In the past few days, I have seen that Zhang Yang does not participate in the discussion of the case, and holds his mobile phone all day long, and I still think that Zhang Yang is deserting.

As a result, I didn't expect that Zhang Yang could know the world without leaving home, but he couldn't keep up.

"Don't worry, Gong Lao, there's more.

Zhang Yang took the phone back, and after some operation, handed it to Gong Lao.

As a result, when Gong Lao looked at it, his old face turned red.

"Show me these things, what?

!" "Tell me when this is!" Gong

Lao glanced at Zhang Yang very dissatisfied.

At this time, on Zhang Yang's mobile phone, there was a selfie of a man and a woman running errands.

"Old Gong, can you see who this woman is?!"

Zhang Yang had a black line.

Gong Lao seemed to realize something, and hurriedly picked up the phone again, and took out his reading glasses to look at it, although it was a little blurry, it was still vaguely recognizable, and the woman in the photo was Wang Lu sitting inside.

"Where did you find this?" said

Gong Boss.

In this way, it is not clear that this Wang Lu was poisoned because this kind of photo was leaked, which caused ridicule and resentment from his classmates.

"Uh......"

"I stumbled upon a post in the post bar, but the content and photos have been deleted. "

I'll just go to this XXX video software, and use the keywords of the medical university to find it, don't you say it, I really found it, and there is a video, do you want to watch it?"

Zhang Yang asked Gong Lao.

"Go, go!"

"Just know that there is such a thing, what do you see?" "

Be careful to catch you kid in there!"

Old Gong blushed.

"Gong Lao, I'm not a child, it's not illegal to watch this kind of website, don't fool me!"

Zhang Yang grinned.

"See what is not illegal?"

"I'll take a look too!"

At this moment, Qin Aiguo heard the news that he had been arrested, and he also came over.

"Get out

!" "You LSP! It's okay to help with the aftermath!"
