Panyun City Criminal Investigation Detachment, in the captain's office, a slightly chubby man was reading the newspaper and drinking tea.

He is the captain of the criminal investigation detachment, Zhao Yunsheng, 55 years old, has been engaged in criminal investigation for more than 30 years, and has been the leader of the detachment for 12 years.

"Knock Knock"

"Enter"

Zhao Yunsheng put down the teacup and newspaper in his hand and looked at the door.

Pushing the door open, a young man. He was dressed in a gray tracksuit, with a handsome complexion, a scar between his right eyebrow, and a simple bracelet on his wrist.

"Captain Zhao, Lang Zhijiao, please take care of me."

This person is the new detachment leader transferred by the Provincial Public Security Department, Lang Zhijiao.

Lang Zhijiao, 28 years old, a doctor of investigation, engaged in criminal investigation two years ago, helped solve several major cases, and was promoted and transferred here by the Provincial Public Security Department.

As he spoke, Lang Zhijiao stepped forward and stretched out his right hand. After a brief handshake, he handed another letter of appointment to Zhao Yunsheng.

"Xiaolang, I received a notice from above, and I have been waiting for you for half a month. If you don't come again, my old bones will fall apart. Zhao Yunsheng said with a smile.

"Look at what you're talking about, you're getting older. Besides, I'm not here to pick you up. Saying that, Lang Zhijiao frowned slightly and said, "By the way, Captain Zhao, I just went to the team to take a look, why are there only two officers on duty left." What about the others? ”

"I just thought that when you came, I would introduce you to the members of the team, after all, there is a good understanding to carry out the work. But early in the morning, I received a report that there was a murder in Tianlu Garden, and it is estimated that they all went to the scene of the murder. Or, you can take a look at our police officer information sheet first. ”

After speaking, Zhao Yunsheng took out a booklet from the drawer and handed it to Lang Zhijiao.

Lang Zhijiao briefly flipped through it, and then put it on the table again. For him, who has an extraordinary memory, the basic information of the police officer has been memorized.

"Captain Zhao, let's leave it for now, and I'll take a closer look when I come back. Also, excuse me, help me arrange a car. Since I'm here, I'm here to work for our team. Lang Zhijiao said with a smile.

Zhao Yunsheng was already retired, but he was just waiting for the new captain to come over and hand over. Since Lang Zhijiao had come to take up his post, he naturally didn't say much, and after a few polite words, he arranged a police car to send Lang Zhijiao to the scene of the murder.

September 20, 2009, at 8:10 a.m.

Tianlu Garden Community, Panyun City, Room 201, Building 9, the blockade line is pulled at the door, and several police officers are busy.

"Xiaobian, how are you and Brother Biao doing? I'm done here, except for a broken bowl and a broken vase, there are no anomalies in the room. ”

It was Cui Tianhui of the criminal investigation detachment who spoke, a young man who was efficient in his work, but he was usually very sloppy.

"The surname is Cui, you Cui Ming! Okay, we're done with this. ”

With the voice, two people walked out of the bathroom, police officers Bian Guan and Liu Hanbiao.

Liu Hanbiao, 42 years old, has been in the team for 16 years and is an old man in the detachment. The other field police officers have only been here for three years, and they are all young people in their early twenties.

"Xiaoyun, what's the result? How did this man die? ”

Liu Hanbiao saw that the body was still being examined, so he walked over and asked about the situation.

I saw a woman in a white coat, with her stomach straight, her legs half-bent, wearing special gloves, beside the corpse, looking down and scrambling through it, and taking something with tweezers.

She is a forensic doctor, Li Xiaoyun, 28 years old, 7 months pregnant.

"The deceased, no fatal injuries or blows were found on the outside, and both fingernails had a mixture of lacquer and wood chips. Vomit in the mouth mixed with blood. The abdomen is noticeably depressed, which is probably due to diarrhea. Large areas of bruising on the face, neck, and skin should be caused by exposed capillaries caused by prolonged dyspnea. It was preliminarily determined that he was poisoned by food, left untreated for a long time, and died of respiratory failure. ”

After Li Xiaoyun finished speaking, he supported his waist with both hands and slowly stood up.

At this time, a young girl ran from the kitchen, still holding a fingerprint bag in her hand.

"Brother Biao, at this time, the whole house, several sets of fingerprints were collected. In addition, it was found that there was a suicide note on the computer screen in the study. ”

Her name is Qin Wan, a forensic doctor, who has been interning for more than a year and has just become a regular. After she finished speaking, she walked towards Li Xiaoyun.

"Sister Xiaoyun, are you okay?"

Qin Wan supported Li Xiaoyun with both hands, and several field workers also waited for Liu Hanbiao, the only old man in the team, to speak.

"After the on-site investigation, there are no traces of a fight, and there is no loss of finances, Xiaoyun and I have the same opinion, and we can basically determine that it was a poisoning death, and it should be suicide." Liu Hanbiao looked left and right, paused, grabbed his beard, and continued: "The old captain said that the new Captain Lang will hand over today. So be it, block the scene, ...... first"

"Wait a minute!"

Before Liu Hanbiao finished speaking, a loud voice came from the door.

Liu Hanbiao and a few people in the house watched casually, and a young man was showing his ID to the police officer at the door after speaking, and then walked through the blockade and into the house.

This person is none other than Lang Zhijiao.

"You are Liu Hanbiao of the detachment, Brother Biao."

"You are?"

Several people in the room were the same as Liu Hanbiao, with questions on their faces, who could go directly to the murder scene with a certificate.

"Lang Zhijiao, I'm new here, I hope to take care of me."

As he spoke, Lang Zhijiao showed his credentials to several people.

"It turned out to be Captain Lang...... Hello Team Lang. I wanted to take everyone back to the team and ...... with you."

"The handover and the affairs of the team, let go of it first. Since you're here, let me investigate the scene first, and you won't have to go back and tell me. ”

As he spoke, Lang Zhijiao had already put on gloves and foot covers, and began to spin around in various rooms.

His face was flat, and there was a lot of stuff around him.

"The situation of the deceased, Qin Wan will tell me." Lang Zhijiao said suddenly.

Qin Wan's eyes widened, looking at everyone left and right, Lang Zhijiao knew that she could still call out her name, which immediately surprised her.

"That's... Man...... Lang Team, deceased, Wu Jianguo, 37 years old, out-of-town, high school chemistry teacher, living alone. After the autopsy, Sister Xiaoyun preliminarily concluded that it was food poisoning, and the specific poison has not yet been identified. That one...... There is also a suicide note in the study, which is supposed to be a suicide. ”

"Are there any relatives?"

"The ......"

After all, it was not a field service, Qin Wan couldn't answer for a while, she looked around, asking everyone for help with her eyes. And Lang Zhijiao stopped and turned his head.

"Well, after inquiry, he grew up in an orphanage, and his wife is in his hometown in the south. However, it has already been notified. She flew back to Panyun City overnight. Now it's on its way. ”

Seeing this, Bian Guan hurriedly said.

"Who reported the case?"

Lang Zhijiao blinked his eyes slightly, signaled, and continued to walk to the study.

"The case was reported by the deceased's neighbor, who was a colleague of the deceased, worked at the same high school, and was a physical education teacher. They would go to work together every morning, and today he called people to no avail, called and found that no one answered. But thinking about the ringtone of the mobile phone in the house, he reported the crime. When we arrived, the technician opened the door and found the deceased lying on the floor. Cui Tianhui said.

After listening to this, Lang Zhijiao didn't speak, but walked into the study step by step and looked at the computer that was on.

“ZnSO4+Mg=Zn+MgSO4?。 Your beauty has stolen my heart. However, we cannot stay together, and the heavens are separated. Lovesickness is painful, and only death can accompany you forever. - Wu Jianguo"

A few simple lines of words, that is, the suicide note in Qin Wan's mouth. Actually, it's the body of an email.

Lang Zhijiao took a closer look, then looked down at the table and keyboard. As he glanced at it, his gaze suddenly rested on a small bottle.

He picked up the vial and looked at it for a moment. In the bottle, there are a lot of small beans. The beans are oval-shaped, smooth and shiny, with about two-thirds of the upper part bright red and the lower third of the beans black.

"Do you know what this is?"

Lang Zhijiao passed the bottle to a few people behind him and asked.

"It's not red beans. There are a lot of red bean and barley porridge on the street, which can be beautiful, and I even bought it for Wan'er......"

It was Bian Guan who spoke, and he smirked at Qin Wan as he spoke, but he was given a roll of Qin Wan's eyes.

"Take it back to the team."

After Lang Zhijiao finished speaking, he went to the bedroom and bathroom, but he didn't speak. When he came to the kitchen, he looked around, looked at the uncleaned pot on the stove, stretched out his finger and dipped it a little, and sniffed it.

"Take this back to the team, too."

Then, Lang Zhijiao raised his head again and stared at the range hood for a long time before pacing out. He was clubbed in the living room, staring down at the corpse.

"Yes, not suicide. It was the ...... who killed him."

Lang Zhijiao raised his head, raised his right eyebrow, stretched out his arm, and pointed to the bottle of red beans in Bian Guan's hand.

Several people looked at Lang Zhijiao, each showing surprise. However, the scar between his right eyebrow made his eyes magical, and everyone believed in his astonishing words.
