Liu Yuzhou drowned mysteriously, and cephalosporin antibiotics and alcohol were found in his body, and even if he did not drown, the disulfiram-like reaction was enough to cause death.

Liu Yuzhou's family strongly urged the police to conduct an autopsy to find out the true cause of his death.

If it weren't for the strong demand of the family, perhaps Liu Yuzhou would have been judged to have drowned accidentally after being drunk.

What exactly are the families worried about? Why do they suspect the cause of Liu Yuzhou's death?

Perhaps by solving this mystery, we will be able to know the cause of Liu Yuzhou's death, because after Shen Baijun's description, he is very likely to have died of a planned drugging murder.

While Li Meng and I went to investigate the returnee Dr. Shen Baijun, Lin Zifan led a team to investigate Liu Yuzhou's family and Liu Yuzhou's social relations.

Back in the office of the Serious Crime Team, Lin Zifan and the others also came back.

As long as they can investigate Liu Yuzhou's social connections, they can lock down the murderer.

"How? Did you investigate anything? I asked impatiently.

Lin Zifan nodded, and told us about the investigation in a deep voice:

Liu Yuzhou, 46 years old, a local, married, has no children, and his parents live in his brother's house and are supported by his brother. Liu Yuzhou has personally opened a software development studio with a good income and has been running it for nearly 20 years. This time, Liu Yuzhou died suddenly, and it was his wife Tian Zhen who strongly advocated an autopsy.

Tian Zhen, 42 years old, from other provinces, unemployed, housewife.

When we went to Liu Yuzhou's house, Tian Zhen was the only one in the family, and Tian Zhen had not yet come out of the grief of her husband's death, and her mental state was extremely poor and her emotions were very unstable......

"How the hell did my husband die? Did you find out? Tian Zhen hurriedly asked.

Lin Zifan thought for a while and replied: "Liu Yuzhou died of drowning, but we found cephalosporin antibiotics in his body, and he drank a lot of wine that day. In other words, even if he hadn't drowned, he would have died of respiratory depression and heart failure caused by a disulfiram-like reaction. ”

After hearing this, Tian Zhen's face became even paler, and she sat down on the chair and didn't come back to her senses for a long time.

"Ms. Tian, did Liu Yuzhou take cephalosporin antibiotics, and did he have any diseases?" Lin Zifan asked.

Tian Zhenmu shook his head and said weakly: "My husband is not sick, he has always been very healthy, he rarely takes medicine, let alone injections. He doesn't take medicine when he has a cold, how can he take cephalosporin? ”

Tian Zhen is right, cephalosporin is a general term for antibacterial drugs, many years ago, everyone used cephalosporin as a conventional anti-inflammatory drug, but as the drug becomes more and more standardized, cephalosporin antibiotics can not be abused, conventional anti-inflammatory drugs are replaced by drugs such as roxithromycin, and cephalosporin antibiotics are more used in clinical medicine.

"After Liu Yuzhou's drowning was discovered, you strongly requested the public security organs to perform an autopsy, right?" Lin Zifan asked her.

Tian Zhen nodded vigorously, her eyes were full of panic, as if she had thought of something terrible.

"Since you asked for an autopsy, it means that you don't believe that Liu Yuzhou died in an accident, so what are you worried about?" Lin Zifan stared at her tightly and asked seriously.

Tian Zhen's body trembled uncontrollably, grabbed a pillow from the sofa beside her, and hugged it tightly in her arms, but it still did not alleviate the fear in her heart.

Lin Zifan comforted her softly and said, "Don't worry, the police will protect your safety, and you can say whatever you know." ”

Tian Zhen subconsciously swallowed a few mouthfuls of saliva, nodded and said: "During this period of time, Liu Yuzhou always had nightmares, and he often dreamed that someone was going to kill him. ”

"Nightmares? Someone is going to kill him? Lin Zifan was very surprised.

"Yes, it's been almost a month, he is always very scared, his mental state is also very bad, and sometimes he is directly scared awake from his dreams." Tian Zhen said weakly.

"What is Liu Yuzhou's personality, do you have many friends outside? Are there any enemies? Lin Zifan continued to ask.

Tian Zhen thought for a while and shook his head slightly: "He opened a studio, and since we have been married for so long, he rarely tells me about work, after all, I don't understand software matters, so I rarely ask." Only on rare occasions would he bring me up. He rarely goes out to socialize, after all, it is a private studio, there is no social interaction, and there are no enemies. ”

Lin Zifan thought for a while and asked again, "How many years have you been married?" How's the relationship? ”

"We have been married for 20 years, and our relationship has always been very good......," Tian Zhen said, suddenly lowered his head, and said with some difficulty: "After getting married, we have never had children, and I was worried that he would leave me because I had no children, but no, our relationship has always been very good, and it has not changed for 20 years." ”

Lin Zifan smiled, his tone became calm, and he chatted with Tian Zhen about homely things: "Did he open a studio when you first met?" ”

After chatting for a while, Tian Zhen was not as nervous as she was at the beginning, her mood gradually calmed down, and she replied with a smile: "When we first met, he worked in software, and he studied software engineering in college. At that time, he worked with his friends to develop software, but when the team broke up, everyone went it alone, and he opened his own studio. ”

"How did you meet?" Lin Zifan asked casually.

At the mention of this, Tian Zhen showed an innocent smile on her face, like a girl who had just fallen in love, and recalled the past with Liu Yuzhou: "We met through introduction, and I heard that the other party was a software worker, three years older than me, and I didn't agree. In my impression, people who do software development are typical science and engineering men, the kind with high IQ and low EQ, obsessed with work every day, and their lives are relatively wooden, I don't like that, and there is no passion in life. But when I met him, I liked him, because he was not what I imagined, he was a very sunny person, very polite in his speech, and careful and considerate in life. I don't know much software, but we never lack a common language......"

Tian Zhen smiled and smiled, the smile suddenly disappeared slowly, no matter how beautiful the memories are, she will return to reality after all. And in reality, her husband has left her forever.

"Just because Liu Yuzhou has nightmares every day, are you worried that he will be killed?" Lin Zifan saw that Tian Zhen's mood had improved a little, and asked softly.

Tian Zhen thought for a moment and replied, "It's not just because he has a nightmare, but once I heard him talking to someone on the phone, saying that retribution is coming." ”

"Retribution is coming? What retribution? Lin Zifan frowned suddenly, very shocked.

Tian Zhen shook his head: "I don't know, since I knew him, he is a law-abiding person, he is still very timid, he doesn't dare to pick up coins when he encounters them on the road, and he doesn't have any enemies outside." At that time, I asked him what the retribution was, and he didn't say anything, just comforted me and said it was okay. I believed him, and I didn't ask ...... again."
