"Good! There you go! ”

Han Qiaoxi inhaled a long breath.

The immediate task is to get to the bottom of it.

Confirm if your mother did it.

Zhou Yuan walked out.

Half an hour later, he returned to the villa, carrying a plastic bag of test strips and a syringe on top of the coffee table.

At this time, except for Tongtong, the whole family is there.

The old man couldn't help but ask: "Xiao Zhou, are you sure that our own family has placed some kind of substance to harm Xiao Tongtong?" Nothing to do with outsiders? ”

"Not bad!"

Zhou Yuan nodded and said: "That kind of fragrance agent is soluble in water, as long as the test paper is dipped in water, about five minutes, as long as the test paper turns red, it means that there is a fragrance agent in the nearby air." ”

"And what are you going to do?"

"Put test strips in every corner of the villa!"

Zhou Yuan said and began to act.

The test strip is not large, and only a drop of water is needed.

He dripped the test strips with water and placed them in various places, including the living room, bedroom, kitchen, and utility room, with a test strip almost every half a meter, like a complex array.

In the living room, it is very quiet!

All doors and windows were closed.

Zhou Yuan walked lightly and sat down.

"Now start the timer, and after five minutes, most of the test strips will turn red."

"What if the test strip turns red?"

Han Baojiang said a rare opening: "It can only show that there is a fragrance agent in this villa, and yesterday Tongtong was poisoned, which is enough to show that there is a fragrance agent in the villa, isn't this an extra move?" ”

"Of course it works!"

Zhou Yuan glanced at Shen Qing: "Of course, I buy test strips not only to test whether there is a fragrance agent in the air, but to find out the utensils that contain the fragrance agent!" ”

The living room was suddenly quiet.

Almost everyone is thinking.

What's the use of finding a utensil for a fragrance?

"I see!"

Suddenly, the old man spoke: "Last night, only Tongtong was poisoned, which means that the appliance where the fragrance is placed is in Tongtong's room, and you didn't find the utensils in Tongtong's room today, which means that someone may have moved the fragrance." ”

"There have been no outsiders in the villa, so the person who moved the toy is the suspect who killed Tongtong, and it is among the three of us!"

"That's right!" Zhou Yuan responded.

"It does make sense."

The old man nodded slowly.

The perpetrator is a thief and transfers evidence, so as long as the utensils are found, it can be determined that the three people living in the villa are suspected.

It's just that the next moment, the old man frowned again: "But, even if you can find the utensils, how can you prove that one of the three of us did it?" Just because no outsiders have ever entered the villa, although it makes sense, it's too far-fetched! ”

"Yes! It's too far-fetched, right? ”

Shen Qing couldn't help but speak: "Even if you can find the utensils that hold the fragrance potion, it doesn't prove that we made it!" ”

Zhou Yuan smiled faintly: "I naturally have a way to find the real suspect!" ”

What the old man said also makes sense.

In terms of the degree of suspicion, Shen Qing has the highest probability.

But even if it is a patrol room, Shen Qing cannot be convicted just because the equipment is still in the villa.

At the end of the day, the real killer has to be found to be the person who placed the incense utensils.

Whoever places the utensils is the real murderer!

Five minutes later, Zhou Yuan began to inspect the test strips.

Most of the test strips have not changed, but the test strips in Xiao Tongtong's room have turned red.

Pale red!

The test strip is related to the content of the fragrance agent in the air, the higher the content, the heavier the color.

And Xiao Tongtong's room is pale red, indicating that the content is not high.

It also proves from the side that this room has opened windows for ventilation.

Continuing to look at the test strips, most of them showed no noticeable change.

But when Zhou Yuan came to the utility room, his eyes lit up.

A few test strips near the utility room have changed colors.

The closer you are to the utility room, the darker the color.

When I arrived at the door of the utility room, the test strip had turned pale red.

Syllable!

Zhou Yuan opened the utility room, and as far as he could see, five or six test strips had turned bright red, reaching the standard of human poisoning.

"Is it hiding here?"

Zhou Yuan began to rummage.

Sure enough, in the drum of an old washing machine, there was a children's toy, exactly the same as the one he found under the pillow of Xiao Tongtong.

"This is it!"

Zhou Yuan returned to the living room, put down the toys, and immediately opened the doors and windows.

He took out the only test strip he had left, dripped it with water, and placed it next to the toy.

Soon, the color of the test strip began to change, but in just three minutes, it turned a bright red!

"Okay, now I've found the utensils."

The old man spoke: "And then? What to do? ”

Zhou Yuan turned to look at Shen Qing: "Now, don't you admit it?" ”

"What does it have to do with me?"

Shen Qing's face was gloomy: "Zhou Yuan, you want to wronged me, right?" Yes! If you can't prove that I put this toy in the room today, I'm not done with you! ”

Zhou Yuan snorted disdainfully: "Do you think I'm a patrol room, and I have to tell evidence in everything?" I'll give you one last chance, tell the reason, why do you want to harm Xiao Tongtong, I may be able to give you a chance to change. ”

"It's not me, it has nothing to do with me, you talk nonsense!"

Shen Qing denied the triple.

"Yes!"

Zhou Yuan nodded lightly.

Refuse to admit it!

Death does not admit it!

It's understandable.

As Fang Cai said, the evidence he took out could not prove that Shen Qing put the toys in Tongtong's room.

So he asked, "Where did this toy come from?" ”

Shen Qing tilted his head sideways: "How do I know." ”

"Have you ever touched a toy?"

"I don't remember."

Shen Qing said coldly: "I cleaned up the entire villa today, it has nothing to do with groceries, naturally it has to be put into the utility room, is there any problem?" ”

Zhou Yuan immediately asked: "In other words, you took the toys from Tongtong's room to the utility room, and at the same time, you don't know where the toys came from, right?" ”

"Even if it is, and then?"

Shen Qing snorted contemptuously, and then his tone softened a little: "Zhou Yuan, we are all a family, whether it is me, Lao Han, or the old man, there is no need to harm my relatives, am I stupid?" Is it any good for me to kill Tongtong? ”

Justified.

Killing Tongtong really didn't do her any good.

Han Baojiang couldn't help but be moved: "Yes, Xiao Zhou, could it be that someone secretly placed toys and wanted to harm our family, and Tongtong happened to sleep in that room and fell for it." ”

"Not really!"

Zhou Yuan shook his head and raised his hand to point at Shen Qing: "It's her!" Shen Qing, since you don't take the initiative to explain, don't blame me for being unkind. ”

"Okay!"

Shen Qing looked angry: "As long as you can come up with evidence, I will be killed by a headfirst today!" ”

"Okay, come and see!"

Zhou Yuan took out his mobile phone, opened the chat software, and then clicked on a video file from Jin San's conversation page.

The video file is surveillance footage.

The scene in the video is a toy stall.

In front of the stall, a middle-aged woman lowered her head slightly and bought two toys.

It looks exactly like the toys on the table.

And that middle-aged woman, whether it is her figure, dress, or general appearance, is very similar to Shen Qing!
