News of someone's death quickly spread in the bar, causing a commotion immediately.

The few uniformed police officers were clearly unable to cope with so many turbulent customers.

When the sergeant leading the team saw this situation, he immediately called for support.

He Jiahui also stepped forward and said, "Brother, let's help maintain order!"

"Okay, thank you for your hard work, brothers." The sergeant nodded.

Everyone brought their police ID cards and began to help maintain order at the scene, and the police sergeant also walked to the stage where the resident singer was standing and picked up the microphone.

"Hello everyone, I am PTU Sergeant Vincent Li. Please don't panic, don't move around, stay in your original position, and don't leave for the time being to avoid accidents.

My colleagues will register your identity in a while, and then you can leave. Please wait patiently, and thank you for your cooperation!

Our police will always be here. If you have any problems or urgent needs, you can contact the nearest police officer and we will help you solve the problem."

And just when the police chief was calming everyone, He Jiahui was already looking at the deceased.

The deceased was a young man, about 24 or 25 years old. His expression was a little distorted and his eyes were slightly protruding. It seemed that he was in pain before death.

If you look closely, you will see that the man's lips are bright red, and there is something like white foam around his mouth, as if liquid has solidified.

"This man was poisoned to death! Judging from the appearance, it is most likely cyanide." He Jiahui was shocked and immediately said to the deceased's companions: "Don't touch the food and drinks on the table, they may be poisonous!"

Then He Jiahui found the police chief again.

"Sir Li, I found that there was residue of an unknown substance on the corner of the deceased's mouth, so the deceased was probably poisoned to death," He Jiahui said.

"Just call me Brother Sen, that's what everyone calls me." The police chief then asked: "You said the deceased was poisoned, was it someone who poisoned him, or was he accidentally poisoned?"

"This is still unknown. Because the source of the poison cannot be determined, it cannot be ruled out that other people's food or drinks are poisonous. I suggest that the kitchen be sealed off immediately, control the chefs, and inform all customers not to eat food or drinks on the table.

drinks."

"Okay, I'll send someone to cordon off the kitchen right away," Sheriff Senge said.

Ho Jiahui continued: "Judging from the situation at the scene, the deceased's friends did not discover the deceased's death at the first time, indicating that the deceased died suddenly in a short period of time with almost no struggle.

I judge that this is most likely caused by cyanide. In addition, the deceased's lips were red and his eyes were protruding. These are symptoms of cyanide poisoning. Of course, the details must be confirmed by the forensic department.

So we have to notify the forensics department to bring more poison detection reagents, and we may need to test a lot of samples to confirm the source of the poison," He Jiahui continued.

…

In Lan Kwai Fong at night, the police force was very strong. It didn't take long for the PTU mobile unit from another patrol team to come to support.

Subsequently, people from the Crime Squad and the Forensic Division also arrived.

"I am Chief Inspector Huang Qifai of the Crime Unit! Where is the deceased?" a familiar voice sounded.

"An old acquaintance is here!" He Jiahui looked at Huang Qifai with a smile.

Brother Sen took Huang Qifai to the deceased. At this time, Huang Qifai also saw He Jiahui beside him.

"Why is it you!" Huang Qifai recognized He Jiahui at a glance.

Huang Qifai was really impressed by this trainee police officer who could solve crimes.

The key is that the case in the police academy cafeteria was obviously solved by He Jiahui, but Huang Qifai was lying flat throughout the whole process. But when Huang Qifai was writing the report, he took all the credit on himself, which is a typical shameless behavior of grabbing credit.

Therefore, when Huang Qifai saw Ho Jiahui again, he naturally felt a little guilty.

"Inspector Huang, we meet again!" He Jiahui said with a smile.

Huang Qifai looked at the police ID on He Jiahui's chest and asked, "Have you graduated?"

"I just graduated not long ago and was assigned to the Sham Shui Po Police Station in West Kowloon." Ho Ka Fai answered.

"From West Kowloon? What are you doing in Central?" Huang Qifai continued to ask.

"I came over for a dinner party and happened to encounter this incident, so I came over to help maintain order!" He Jiahui continued to answer.

Sheriff Sen Ge asked: "Inspector Huang, it turns out you guys know each other!"

"Of course we know each other." He Jiahui chuckled and continued: "Inspector Huang and I are old acquaintances."

He Jiahui did not mention the murder case in the school cafeteria, and the more this happened, the more guilty Huang Qifai felt.

So Huang Qifai quickly changed the topic: "Let's chat later when we have a chance. I'll first understand the case. Can the cause of death of the deceased be determined now?"

"There was some unknown substance around the mouth of the deceased. It is initially determined that he was poisoned to death. The poison was probably cyanide." Brother Sen directly repeated He Jiahui's conclusion.

"Is it cyanide poisoning? It is very likely that he was poisoned." Huang Qifai turned around and called the people from the forensic department over, asking them to determine as soon as possible whether the deceased was poisoned.

Huang Qifa then began to ask the deceased's companions to obtain the deceased's personal information.

The name of the deceased was Yu Zhenghuang, a graduate student at the Chinese University. In addition to him, there were six other people eating at the same table.

The first person to be questioned was a short girl, wearing a pair of glasses, and weak. At this time, she was crying very miserably and looked very sad.

The woman's name was Liu Wei, who was also a graduate student at the Chinese University. She was in the same department as the deceased, but one level lower than the deceased, who was her senior.

The second one is a short, smart-looking man.

The man's name was Lin Zhijian, who was also a graduate student at the Chinese University. He and the deceased were classmates at university. They later studied in the same department as graduate students and had the same tutor. The two had been classmates and friends for many years.

Today was also his birthday. Because he was familiar with the deceased, he invited the deceased to his birthday party.

The third person questioned was a tall man.

He, Lin Youqiang, is Lin Zhijian's cousin. Today he came to celebrate his cousin's birthday. It was the first time for him to meet everyone present except Lin Zhijian.

The fourth person is also short in stature and looks very ordinary. He also looks very introverted and stutters when speaking.

His name is Ma Minghao, who also graduated from Chinese University. When he was in college, he was classmates with Yu Zhenghuang and Lin Zhijian. However, he did not go to graduate school and worked after graduating from university. As an old classmate, Ma Minghao was also invited

Attended a birthday party.

The fifth one is a man wearing glasses, who looks to be in his late twenties.

This person's name is Xue Youlin, who works as a teaching assistant at the Chinese University and is in the same department as the deceased. As a teaching assistant, he usually has more contact with graduate students and is familiar with each other, so he was invited to attend Lin Zhijian's birthday party.

The sixth one is a girl, the girlfriend of assistant teacher Xue Youlin. She was not familiar with the deceased and came here solely to accompany her boyfriend.

Huang Qifa just learned the identity of the deceased and his friends, and the forensics department also got results.

The forensic doctor said: "Inspector Huang, I extracted the residue from the mouth of the deceased and conducted a test. It is indeed cyanide. Therefore, it can be initially determined that the deceased died of cyanide poisoning. More detailed information will be required after an autopsy.

Only then can I give you a report."
