The Case of Love

Chapter 8 Survivors

"The preliminary diagnosis is acute drug poisoning." Zhou Yifeng replied.

"Uncle police, I'll ask my dad to take me back to school right now!" Before Zhou Yifeng could answer, the phone was hung up with a "beep" sound coming from the phone.

After confirming that Zhou Anqi would come back to cooperate with the investigation, Zhou Yifeng and Su Xiaohan returned to the scene. The trace detection personnel had already extracted fingerprints at the scene and took away the water cups of several girls and several oranges on the table for testing.

It was past 2 a.m. when Su Xiaohan's phone rang. She picked it up and saw that it was a message from her sister. She was worried about her and hadn't slept.

Judging from the current situation, Su Xiaohan thought it was impossible to go home, so she sent a message to her sister, asking her to have a good rest.

Dozens of minutes later, Zhou Anqi, the only survivor of Dormitory 613, hurried back, and her father came with her.

In Song Yan's office, Zhou Yifeng and Su Xiaohan asked her questions together. They were eager to determine whether the deaths of these three girls were suicides or homicides.

"Zhou Anqi, don't be nervous. Just answer our questions and tell us everything you know." Seeing that Zhou Anqi's hands were shaking and her face was pale, Su Xiaohan comforted her.

Zhou Anqi nodded and waited for them to ask questions with tears in her eyes.

"Zhou Anqi, I want to know, in recent times, have Lu Ying and the other three come into contact with any special people, or done anything special, or said anything special?" Zhou Yifeng looked at Zhou Anqi and guided her to answer the questions according to his ideas.

Zhou Anqi wiped her tears with her sleeve, thought for a while and said, "We are about to enter the third year of high school. We are in the classroom almost every day for classes or review. I haven't been home for two weeks and just went back this week. Lu Ying and the other three haven't been home for almost a month. I... really can't think of anything special."

"Who do you have the best relationship with among the people in your dormitory?" Su Xiaohan asked, recalling the dormitory relationships in high school.

"We all have a good relationship, but the best one is with Lu Ying. She tells me everything, and I tell her too." Zhou Anqi answered without hesitation.

Su Xiaohan smiled. Girls of their age being able to exchange secrets with each other was a symbol of friendship.

At Su Xiaohan's prompt, Zhou Anqi talked about many things about Lu Ying. She and Lu Ying were classmates and good friends in junior high school. In high school, they were assigned to the same class and shared the same dormitory, and they were inseparable. According to Zhou Anqi, Lu Ying was in a bad mood recently, and she and her boyfriend seemed to be breaking up. Lu Ying has been very depressed during this period.

After hearing Zhou Anqi mention Lu Ying's boyfriend, Zhou Yifeng and Su Xiaohan both felt it necessary to find him to talk. Zhou Anqi told them that Lu Ying's boyfriend was Huang Anran, also a student in Class 2-3 of Senior High School.

Knowing that they were looking for Huang Anran, Song Yan cooperated very well and contacted Huang Anran through the teacher of Class 2-3 of Senior High School.

The head teacher of Class 2-3 of Senior High School is called Sun Can, and he is already on his way to school.

Ten minutes later, a sturdy and handsome boy appeared at the door of Song Yan's office. The news of Lu Ying and the other two had spread all over the school. Huang Anran looked like she had just cried, her eyes were swollen and there were traces of tears on her face.

Huang Anran told them that his parents knew about him and Lu Ying, and were worried that it would affect his studies, so he had no choice but to break up with Lu Ying a few days ago. Lu Ying disagreed, crying and making a scene, and even said that if he insisted on breaking up, she would commit suicide. Zhou Yifeng was suspicious when he heard Huang Anran mention suicide. If Lu Ying committed suicide because of a broken heart, then what were the reasons for the other two girls?

While they were questioning Huang Anran, Ma Nan and Zhu Xiaofeng had already retrieved the dormitory's surveillance video.

There is a surveillance camera at the entrance of each floor of the girls' dormitory building. However, in order to protect the privacy of the students, the camera is only facing the direction of the corridor. From the surveillance, after school in the evening, Lu Ying and the other two entered the dormitory one after another and never came out again. Except for Wu Nan, who found Lu Ying and the other two dead, no one opened the door of dormitory 613.

At about six in the morning, Zhou Yifeng, Su Xiaohan, and Zhu Xiaofeng returned to the police station. Forensic doctor Sun Yidan already had preliminary autopsy results.

Seeing Zhou Yifeng, Sun Yidan said, "Captain Zhou, I found a large dose of cyanide in the bodies of the deceased and in the thermos cups they used. If the dose of this substance is small enough, there will be no obvious changes in the body, similar to a sudden heart attack. If the dose is large, since the mechanism of cyanide poisoning is cellular asphyxiation due to lack of oxygen, the venous blood is rich in oxygen, and bright red livor mortis can be seen on the surface of the body. Especially after the autopsy, it can be seen that the blood does not coagulate and is bright red, the kidneys, liver and other organs are congested and swollen, and the gastric mucosa is widely bleeding."

"Hydride? Did these three girls take hydride?" Zhou Yifeng asked.

"That's right. All three girls have hydride in their bodies. I suspect they may have agreed to drink it together beforehand," Sun Yidan deduced.

"Drink it together! It seems like they are committing mass suicide. But what kind of reason could make three girls commit suicide together?" Su Xiaohan exclaimed.

Although based on the current situation, it is possible that the three girls committed suicide, she finds it hard to believe.

"We can't rule out homicide. Someone poisoned the water they drank!" Zhou Yifeng suspected.

"Captain Zhou, there is no evidence yet to prove that someone poisoned the girls. No other people's fingerprints were found on the cups and kettles that the girls often used. In one of the large kettles, there was 500 ml of water soaked with roses, and the other two cups also had this kind of water, which all contained potassium cyanide." Sun Yidan explained to Zhou Yifeng.

After asking Sun Yidan a few more questions, Zhou Yifeng and Su Xiaohan returned to the police office. Ma Nan and Zhu Xiaofeng were investigating the source of the hydride.

It was the first time that Su Xiaohan stayed up all night, and her face was full of fatigue. At Zhou Yifeng's order, she prepared to go home and take a nap. As soon as she entered the house, she saw her mother and sister sitting on the sofa in the living room, as if waiting for her.

"Mom, sister, you didn't stay up all night, did you?" Su Xiaohan confirmed with them.

"Mom is worried about you, and I am worried about you too, Xiaohan. Mom and I have discussed it and are ready to talk to you." Su Xiaoxin stood up and said.

Before this, Su Xiaoxin had always supported her sister to realize her dream, but she did not sleep last night and thought about it all night. She doubted whether her support for her sister was correct. She thought that her sister, a girl, was at the crime scene all night, which was scary for her. Moreover, this was only the first time. As long as she was a criminal police, there would be a second, third, and more times in the future.

"Mom, sister, I'm so sleepy. I'm going to bed. You guys should sleep for a while too. We can talk after I wake up!" After saying that, Su Xiaohan hurried upstairs.

"Xiao Han, change your career! Don't be a criminal policeman anymore!" Su Xiaoxin didn't want to beat around the bush and went straight to the point.

Hearing this, Su Xiaohan stopped running upstairs and asked in confusion: "Sister, haven't you always supported me? Why do you suddenly say this?"
