"When I got to school, I found out that they had gone to play games all night together, and I really didn't have anything to do, so I went back again."

When the two officers heard him say this, one of them immediately asked with a serious face.

"You admit that you went back at that time, but the other classmates in the KTV said that they hadn't seen you, so what did you do when you went back?"

"I originally wanted to go back and ask them if they had any plans to eat supper for a while, but as soon as I got to the end of the corridor, I heard a voice from their box, and they were about to disperse after rapping these songs, so I thought about it and didn't go in at that time."

"That means you just went back once, but you didn't deal with them."

Hearing this, He Yan nodded hesitantly.

"And when did you get out of there?"

One of the policemen immediately asked again.

Since he said that he originally just planned to invite these people to have supper together, after finding out that they already had the next plan, the other party should have left this KTV immediately.

When He Yan heard them ask, his eyes moved slightly.

He recalled it carefully in his mind, and determined that when he left the KTV, he left an extremely remote alley at the back door of the KTV, and he saw that there should be no surveillance around the alley.

After a moment of silence, he finally spoke: "I should have left the KTV around eight o'clock." ”

He was sure that no one should be able to find out when he left KTV, so he told a small lie about the details of this time.

But who knew that after he said this answer, the two policemen sitting opposite him sneered.

"You said you left around eight-ten-year?"

Seeing the sarcasm in the eyes of the two policemen when they looked at him, an ominous premonition inexplicably rose in his heart.

"yes, I'm sure I'm around eight-ten-a-......."

Before he could finish his sentence, he saw the officer sitting on the left side wink at the officer sitting on the other side, and the next moment the officer took out a folder from under the table.

"You said that you left the KTV around 8:10, so I want to confirm with you, what's going on with this video screenshot?"

A clearly enlarged photo was pushed in front of He Yan, and the young man slowly lowered his eyes, his gaze fell on the photo, and his eyes widened.

It was a picture of a long figure in a white shirt passing by a corner.

The video of this photo should have been in the office area or kitchen area of the KTV at the time, and he just didn't notice the video inside the KTV, and the side bridge was captured by the video for a flash.

"The time of this video is half past eight, and you are still inside this KTV, so you want to tell us, what were you doing at that time?"

There was obviously a cold sweat on He Yan's face, his eyes widened, staring at the content of the photo for a moment, and he was silent for a moment before he raised his hand violently to cover his face.

"Well, I admit it, I admit that I left the KTV at nine o'clock in the evening that day."

The two officers saw that he was finally relieved, and the two of them couldn't help but breathe a little relieved, and one of them continued to ask.

"So what did you do that day when you stayed in that KTV for so long while many classmates were not paying attention?"

He Yan narrowed his eyes slightly, and was silent for a moment before he said slowly: "In order to give medicine." ”

The other party was an extremely cunning person, but this time he admitted it quite neatly, and everyone present was stunned, and the police officer immediately asked when he saw this.

"Who drugged whom?"

"Xie Nian, and her friend who sleeps with her." He Yan replied dejectedly.

"Why did you drug both of them?" The policeman frowned and asked another question: "What kind of medicine did you order?" ”

"I don't know what it is, I heard that it is a hallucinogen, and after the person took it, he leaned over and whispered to the person a few times what he wanted the other person to see."

"That person will be trapped in hallucinations when the potion has completely subsided."

This was consistent with the hallucinogen's evidence provided by Xie Nian, and the two officers nodded quietly, and then continued to ask.

"What about the reason for the drugging?"

After this question was asked, the expression on He Yan's face finally stopped being lifeless just now.

His lips trembled for a long time, and then he suddenly raised his hand and put his clothes on his face, and his shoulders shook as if he was immersed in great sorrow.

"Two police officers, have you heard of the lake throwing case that happened at the school a year ago?"

Regarding the case of throwing into the lake, although it was not mentioned in the evidence provided by Xiannian, these two policemen had been in the school for a long time, and they had heard a little about it.

"Of course we've heard about it." Another police officer in charge of recording answered, frowning.

"Does this have anything to do with your poisoning?"

"Of course." He Yan smiled ugly, and was silent for a long time before saying in a sad voice.

"The girl who threw herself into the lake back then was my childhood sweetheart's girlfriend."

The two police officers had never heard of the background of the victim who threw himself into the lake, and they frowned when they heard this, and listened to the other party continue.

"My girlfriend was in a bad mood for some reason that day, and accidentally fell into the lake, Xie Nian and her friend were obviously present, but they didn't come to the rescue, I hated the two of them because of this incident, so I gave them this hallucinogenic drug."

"I kept telling the two people who were in a trance after taking hallucinogens to remind them of what my girlfriend was like before she threw herself into the lake."

"As a result, I didn't expect those two people to be overwhelmed by the burden of hallucinations, and even wanted to commit suicide."

When the two policemen heard him say this, they couldn't help frowning.

"You've poisoned them a few times."

According to the information provided by Xie Nian, they all knew something about the hallucinogen, and knew that the effect of the drug would not exceed 24 hours.

However, Xie Nian and the others returned to school from KTV, and it was two weeks since they and his friends attempted suicide.

If the other person is really overwhelmed by the hallucinations in his head, he should wait for the opportunity to act after 24 hours.

"I've been poisoned, maybe five or six times."

After a moment of silence, He Yan's answer did shock the two officers in front of him.

"Except for the one time at KTV, when did you start the other times?" The officer in charge of the questioning continued to ask.

"Most of the time it's when they go back to the dorm and fetch water in the water room."

"Water room fetching? Which water room? ”

He Yan was slightly silent, and hesitated for a moment before speaking: "It's in the water room in the girl's dormitory building." ”

It is impossible for boys to enter the girls' dormitory building, and the other party wants to be drugged, and in such a place, does the other party have any accomplices?

The officer's eyes flickered, and he immediately asked the question in his heart, and the truth was not what he expected.
