"If Miss Qin still remembers, I hope you can say it and cooperate with the police to solve this old case." Wang Jian's Chinese tone was heavy, and his eyes stared at Qin Meimei.

Qin Meili didn't answer Wang Jianguo's words in time, but glanced at Fang Xiaoyun. Liu Yi said: "Guo Dongliang's death is not an accident, the whole thing still needs to be considered in the long run, if the real cause of Guo Dongliang's death can be proven, I think you should not be as hesitant as now." ”

After listening to Liu Yi's words, Qin Meili had some reactions, and said suspiciously: "Are you saying that Dongliang didn't drown after being drunk?" Qin Meili looked nervous, and her hands tightly grasped Fang Xiaoyun's arm.

"Yes, I'm just suspicious now, but the evidence still needs to be collected a little bit." Liu Yi thought to himself, there were too few clues on the scene to make a normal judgment.

"You're guessing without evidence?" Qin Meili sat up suddenly, and her tone changed a lot, like a housewife bargaining in the vegetable market.

Liu Yi thought to himself that if the cause of Cong Zhijun's death and Guo Dongliang's cause of death were the same, then finding the murderer would prove all this. But there is a suspicion, if the murderer is a student at school, it is still a little difficult to come out and kill people, is it ...... A figure suddenly appeared in Liu Yi's mind.

"Another person was found at the scene, and it was a woman." Wang Jianguo's words shocked everyone present, Wang Jianguo coughed and continued: "A broken fingerprint was found on a wine bottle at the scene, and there was a shoe print of a woman's high heels at the door, which means that Guo Dongliang had seen a woman before he died." The more Wang Jianguo spoke, the more heavy his tone became.

"Master, why didn't you file a case at that time?" Xu Wei hurriedly asked.

"The evidence is insufficient, the clues are incomplete, and the technology of the day cannot use fingerprinting. It could not be confirmed at the scene that he was killed, so in order to prevent regional panic, the case was hastily closed. Wang Jianguo shook his head and said.

"Master, this is too disrespectful!" Xu Wei complained.

Wang Jianguo sighed and said, "I was just a little criminal policeman at the time, and my ability was limited!" ”

"It's not too late to find out, does Guo Dongliang have close contacts with other members of the opposite sex?" After Liu Yi comforted Wang Jianguo, he then asked Qin Meili.

"I don't know about this, I don't usually worry much about this problem, what problems can arise in his usual two-point and one-line life?" Liu Yi felt that Qin Meimei's appearance was not a person who cared about Guo Dongliang.

"You're with him because of the money, right?" Liu poked Qin Meimei's heart all the way.

Qin Meili hugged her arms and snorted: "What? Is he handsome? Isn't it just that there is more money, isn't it that we girls looking for men like this? Are you looking for such a poor and sour person? ”

Liu Yi didn't quarrel with Qin Meimei, but felt that the girl in front of him was too frivolous and didn't seem to have any concept of love.

Qin Meili continued: "I remember, the night before Christmas, Dongliang seemed to tell me that the school's store would be his. ”

"Is that his? What about Cong Zhijun? Xu Wei hurriedly asked.

"At that time, I also had this question, but then I thought about it carefully, Dongliang and him are not very compatible, Xiaoyun may not know this, Dongliang died before I told her the truth. Fortunately, Xiaoyun is broad-minded and doesn't care about anything! Qin Meili hugged Fang Xiaoyun's arm as she spoke.

Liu Yi saw Fang Xiaoyun smile perfunctorily a few times, and then his face returned to calm. Qin Meili said again: "Actually, it's nothing, it's just that the two of them often have conflicts when they calculate the money." Either he takes more, or you take less. Qin Meili said as if she was a resentful woman. Fang Xiaoyun didn't interject, just listened silently on the side.

"Does Guo Dongliang often tell you about school?" Liu Yi asked.

"There aren't many things in school, and sometimes it's just some teachers and teachers intriguing, students fighting, or teacher-student love." Liu Yi was more curious when he heard this, and suddenly remembered a person's name.

"Li Hanmei, have you heard of this person?" Liu Yi hurriedly asked.

"Li Hanmei, Li Hanmei? Yes, yes, this woman seems to be, it seems to be ......" Qin Meili glanced at Fang Xiaoyun a few times, as if she was deliberately avoiding this name.

"Li Hanmei is Cong Zhijun's ex-girlfriend, beautiful, don't hide it so much, just say it." Fang Xiaoyun is very open to this matter.

"Yes, I heard Guo Dongliang say that some people secretly like Cong Zhijun, but they didn't confess to Cong Zhijun head-on, as if they were still students." Qin Meili picked up the water on the table, and then walked to the bedroom, "You guys wait a minute, I'll take a pill!" ”

Liu Yi looked at the bedroom, he was indeed taking medicine, and when Liu Yi turned around, he just looked at Fang Xiaoyun for a second, and Fang Xiaoyun just smiled at herself. Liu Yi felt that the woman in front of her was not ordinary, and then saw Qin Meili return to the living room after taking the medicine, but as soon as she sat on the sofa, she felt a little uncomfortable in her stomach. I kept my hands on my stomach.

"Beautiful, what's wrong with you?" Fang Xiaoyun hurriedly stepped forward and asked with concern.

Qin Meili couldn't speak at this time, and her mouth let out a painful moan. At this time, blood also flowed from the corners of Qin Meimei's mouth, and it didn't take long for Qin Meimei's eyes to roll, and the whites of her eyes were already revealed. Wang Jianguo immediately dialed 120. Liu Yi pointed to Fang Xiaoyun, who was sitting next to Qin Meili, and said, "Don't move!" Fang Xiaoyun was not surprised, but was very calm.

It didn't take long for Wang Jianguo to cordon off the scene, and when Wang Lan arrived at the scene, "the victim should have died from drug poisoning, and to determine the cause, we need to go back and test the drugs the victim had taken and the water she was taking." ”

"Sister Lan, and this pot of water on the table." Xu Wei reminded Wang Lan.

Wang Lan took the body back to the police station for further examination, and Wang Jianguo and others collected evidence at the scene. Xu Wei said: "Miss Fang, it's a pity that your friend died in front of us, and please go back and cooperate with our investigation!" Needless to say, among the people present, Wang Jianguo and others, only Fang Xiaoyun had seen Qin Meili beforehand, and she was the most suspicious.

"Me? Do you suspect that I killed my best friend? So what is my motive for committing the crime? Liu Yi's perception of Fang Xiaoyun is right, and the woman in front of him is not easy to deal with.

"The motive for the crime? You may have to fight for Cong Zhijun? This is still very understandable! Xu Wei immediately answered Fang Xiaoyun's question. At this time, Fang Xiaoyun didn't know how to answer, so she could only go back with Wang Jianguo and others.

The interrogation room of the Southern District Bureau has always been very effective, and no matter which suspect comes here, he has to confess the truth. After several cases, the policemen in City C called this place the "confessional".

When Fang Xiaoyun sat here again, her identity had changed, and Wang Jianguo stared at the silent Fang Xiaoyun in front of her for a long time. Liu Yi said: "Brother Wang, Sister Lan is doing an autopsy, and some things have to wait for the autopsy report and laboratory report to prove all this." Wang Jianguo nodded, "Ask her first!" ”

"Do you have a bad relationship with Qin Meimei?" Wang Jianguo asked.

"Good! Don't you all see it? I didn't poison it, I don't know why she was like this, really! If I poison you, you're all there, how can I do it? Fang Xiaoyun argued.

"You've been staying at Qin Meimei's house for twenty minutes before we arrived, and that's enough time for you to poison." After Wang Jianguo finished speaking, Wang Lan rushed over panting.

"How's Xiaolan's autopsy report?" Wang Jianguo asked.

"The water the victim drank did not detect any toxic substances, the medicine was also a normal drug, and the poisoning did not occur in your presence, but before that, the drug that the victim was taking was aspirin, which introduced analgesics and anti-inflammatory drugs." Wang Lan's reply surprised the people present.

"I'm not poisoned, really, beauty is just talking to me. I, too, I don't know what's going on! Fang Xiaoyun's voice began to choke.

"Sister Lan, is it stomach bleeding?" Liu Yi asked.

"Yes, this is also the main side effect of aspirin, but as long as you don't take it in large amounts for a long time, there will be no problem, and you must consult a doctor before taking it. But the victim should have had a serious cold, and judging from the amount of medicine at the scene, the victim had been taking it for at least a month. ”

"Aspirin is easily absorbed into the cells of the stomach parietal gas, some of which produce stomach acid, which promotes digestion, and prostaglandins reduce the amount of stomach acid and help produce mucus, which can protect the stomach against stomach acid. But aspirin reduces the production of prostaglandins and inhibits the enzymes that synthesize COX-1, which is how aspirin relieves stomach pain. Aspirin itself is also an acid that can cause bleeding and ulcers if taken repeatedly, or worse. Liu Yi's explanation made Xu Wei look confused. Xu Wei is completely "blind" in this regard.

"You! It's just learning the wrong major! Wang Lan had to praise Liu Yifan.

"I understand a little bit, Qin Meili is a drug that accumulates in the body and cannot be absorbed, and then produces toxicity, Qin Meili should be in the category of serious situations. And just now we just stepped on the spot, and just happened to bump into the scene of her poisoning and death! Liu Yi said.

Zhang Jie rushed over from outside. Zhang Jie said: "Brother Wang, although there are Fang Xiaoyun's fingerprints at the scene, from the location analysis, it seems that it has nothing to do with the victim's death. Zhang Jie made a report as soon as he got the on-site report.

"What about the master?" Xu Wei hurriedly asked.

"Insufficient evidence, release!" Wang Jianguo also had no choice, and the scene really couldn't show that Fang Xiaoyun did it.

"I didn't kill anyone, you can investigate as you like!" Fang Xiaoyun said angrily.

"We also hope so, thank you Miss Fang for your cooperation!" After Wang Jianguo finished speaking, Fang Xiaoyun left the interrogation room.

"The master just let people go?" After Xu Wei saw Fang Xiaoyun leave, he immediately asked a low-level question.

"Didn't I say it! The evidence is insufficient! If you can find proof that he killed her, let's arrest her immediately! Wang Jianguo scolded Xu Wei.

"Master, do you have to keep tracking?" Xu Wei asked.

"Of course, you continue to track, and the police station will gather at eight o'clock tomorrow morning, and we will continue to dig through the cocoons and find clues in these files."

"Brother Wang, now the suspect can basically draw a few!" Liu Yi took out a piece of paper, on which were several insiders who had been tried in the past few days. Liu began to draw with the black pen on the table.

"Fang Xiaoyun, Wang Shuang, Wang Rui and Zhang Yang! All four of them are suspicious! Liu Yi put down his pen and took a cigarette handed over by Wang Jianguo.

"Zhang Jie and I will leave now, I don't believe it, I won't stare at them all night, I won't find their loopholes!" Xu Wei was about to leave after speaking.

"Xiaowei, the murderer has not shown his feet for so many years, and the murderer must be very cautious. If you can't find a clue, don't be discouraged! Wang Jianguo hoped that Xu Wei and the others would not be discouraged because they could not find evidence.

"Don't worry! Master! After saying that, Xu Wei and Zhang Jie left the Southern District Bureau, and Wang Jianguo asked Liu Yi to go back to rest, after all, Liu Yi is still in the recovery period. Liu Yi said before leaving: "Brother Wang, Chen Xiaoyan must not let go of this line."

"Don't worry, I've sent someone to watch you!"
