Ning Hao frowned involuntarily, if it wasn't Lai Qing's child, it would be enough to prove that Guo Xue was not a good girl.

So who is this child of hers? Could it have something to do with this bizarre homicide?

Wang Feiyu continued: "According to the forensic examination, the deceased had obvious signs of suffocation, and his heart blood was dark red. The lungs are congested and edema, the myocardium is ruptured, and death from heart failure. All of this is consistent with the death characteristics of the drowning victim, the only difference is that the forensic doctor has detected a lethal dose of aconitine in the contents of the liver and stomach, as well as in the blood of the heart. So, the thing that poisoned the murderer was aconitine. ”

"Is there this toxin in Jack Daniel's whiskey?"

"That's right, so you're right." Wang Feiyu's tone was full of affirmation of Ning Hao, "Your thinking is very delicate, and you are one of the witnesses at the scene of the crime, so you will need your help for further investigation of the case in the future, but it's just ......"

"Just what?"

"Now we can only temporarily lie to the family of the deceased that the deceased died by drowning. Due to the special nature of the case, until the murderer is found, in order not to cause panic in the school, it can only be done temporarily. However, I really hope that you will be able to observe the movements of the other four people, and then we will interrogate the suspects separately, and you are one of them. ”

Hearing this, Ning Hao's face sank.

That's right, of course he knew that he was not the murderer, but he was also at the scene of the crime last night, how could the police rule out his suspicion.

And it is also himself who provides the evidence.

In this case, the police will focus on him, after all, many perpetrators will deliberately provide some clues to avoid the suspicion of the police.

Ning Hao pinched the note in his trouser pocket, wondering whether to give it to Wang Feiyu.

"Officer Wang, I will cooperate vigorously, and besides, I can agree to undergo a polygraph test."

"The main thing for us now is to collect as much evidence as possible. Even if there is a polygraph conclusion, there is no other evidence, and a single polygraph conclusion cannot be used as the basis for determining the facts, that is, it cannot be directly admissible as evidence, but only a means of identifying evidence.

In addition, even if the suspect agrees to take a polygraph, the conclusions drawn cannot be directly used as evidence against the criminal. Therefore, it is still necessary to focus on getting direct evidence and bringing the murderer to justice. ”

……

After hanging up the phone, Yan Xiaoyu asked, "Is it a call from Sheriff Wang?" ”

Ning Hao nodded and said, "He told me that the fetus in Guo Xue's womb is not Lai Qing's. ”

Hearing such news, Yan Xiaoyu was stunned. She shook her head and said, "What a green hat Senior Lai has been wearing on his head for so long!" ”

"I hope that Senior Lai will not only mourn now, but also mourn." Ning Hao sighed, "By the way, in this case, you and Guo Xue are good girlfriends, do you know what boy she is secretly dating with?" ”

"I don't know about boys, but recently Guo Xue offended a girl! She is Dai Ying from the Department of Journalism and Media and a member of our Student Union. ”

"Dai Ying?"

Yan Xiaoyu nodded, and immediately said, "By the way, I'll show you something." ”

She began to open her bag, rummaging through it, muttering, "Strange, where did it go, I obviously put it in my bag yesterday." ”

"What are you looking for?"

A red note with words threatening Guo Xue. I picked it up on the floor yesterday while cleaning the student union office. ”

Hearing the red note, Ning Hao was instantly extremely embarrassed, if he took out the note, wouldn't it expose the matter of rummaging through the girl's bag last night?

Pretending to be calm: "What is written on it?" ”

"I wrote that Guo Xue would not die well...... Etcetera. Yan Xiaoyu closed her bag and continued, "It is Dai Ying's handwriting, she writes for the student union, and sometimes shows me the manuscript, I am very familiar with her handwriting." Yesterday I struggled all night about whether to tell Guo Xue about this, but something like that happened......"

Ning Hao looked at Yan Xiaoyu, it turned out that he had wrongly blamed her before. Now it is possible to rule out Yan Xiaoyu's suspicion, so if it is Dai Ying...... It's unlikely!

The girl named Dai Ying was not present at all last night.

Moreover, Guo Xue also said that the bottle of wine was a treasure in her father's bar. If it was poisoned by his own father, this would not be justified.

Now the breakthrough is wine, and the fetus in the womb!

Thinking of the fetus, Ning Hao calculated the time and asked: "Xiaoyu, did Guo Xue have any abnormal behavior in July, or did she have any boyfriend before entering college?" ”

Yan Xiaoyu and Guo Xue were already good friends in high school, and she was naturally familiar with Guo Xue's movements.

She thought for a moment and said, "By the way, during the summer vacation in July, after we applied for college, we went to the island together for a vacation. ”

"Did you go with her?"

"No, it's four people, as well as Ma Yang and Wang Qiwen."

Ma Yang and Wang Qiwen both went.

And it was at that time that Guo Xue was pregnant, and it was extremely scary to think about it, that is to say, Guo Xue had found out that she was pregnant, but she did not take measures to get rid of the fetus.

So what exactly is she planning? Or, she simply wants to keep the fetus, after all, life is precious.

The child's father is either Ma Yang or Wang Qiwen.

Ning Hao asked: "You are a girl, you know the minds of girls best, did you find that Guo Xue was too close to one of Ma Yang and Wang Qiwen at that time?" ”

"How do you ask this?" Yan Xiaoyu looked at Ning Hao curiously.

"I just suspect that Guo Xue's child is one of them."

Yan Xiaoyu seemed to understand something, with an incredulous expression. She said: "I only know that Wang Qiwen has always liked her, but she has been rejected repeatedly. ”

Ning Hao knew where to break through.

Thinking of this, he said to Yan Xiaoyu: "Do you want to help Guo Xue get the snow?" ”

"Well, she's my best friend. I haven't slept all night since I went back last night......"

"Okay, we have to determine now whether the fetus in her womb is Ma Yang's or Wang Qiwen's."

When Yan Xiaoyu heard this, he was a little nervous, and a trace of sadness appeared on his face: "If it were one of them and killed Guo Xue, I would ...... I really don't want to accept that there are murderers around me. Besides, Ma Yang grew up with me since I was a child, and I don't believe he would do such a thing. ”

"In this case, it is all the more important to find out the murderer, because the murderer is all around us, and if we sit idly by, the murderer will become a hidden danger to us in the future."

Hearing Ning Hao say this, Yan Xiaoyu nodded: "Then how do we verify it?" ”

"Paternity test!" Ning Hao said resolutely, "Just find a way to get Ma Yang and Wang Qiwen's hair." ”

"Then it's up to you, I'll leave the rest to me, and let's find out the real culprit together and let Guo Xue be blind."

Yan Xiaoyu's face showed a hint of flushing, feeling that the boy in front of him had an indescribable charm.

Ning Hao looked at her flushed face and asked, "What's wrong?" What is wrong with you? ”

"No...... Then I'm going to the student union now, and I'm free to make an appointment! ”

Yan Xiaoyu turned around and trotted away.

Looking at the back of Yan Xiaoyu leaving, the corners of his mouth hooked, then he took out the note in his pocket and dialed Wang Feiyu's phone: "Officer Wang, I have two important clues to provide to you......"
