It was night, and a small orange table lamp in the discussion room of the Hangzhou Municipal Bureau’s serious crime team was like a candle illuminating faint light. Under the light, a middle-aged man in his forties was holding an old-fashioned hero pen and scratching a blank A4 paper for a while, and then placing and changing it. A4 paper was full of his chaotic thoughts. Not far from him was placed on the table, a wooden photo frame was placed in the photo frame. In the photo frame was a young man in a police uniform with a serious face and a young girl with a bright smile in gold-rimmed glasses.

A middle-aged female forensic doctor wearing a white coat and thin face with a slight corner of her eyes was placed on the desk where the middle-aged man was wearing, and then patted his shoulder and said in a low voice: "Old Luo, take a break. You have been busy for three days and three nights, even if you take a short look."

Team Leader Luo woke up from his meditation state, looked at the forehead beside him and breathed a sigh of relief, "It turned out to be you, Forensic Xu. I thought those kids would be willing to come over."

"Old Luo, don't say anything. They are all cute little guys. If they hadn't collected evidence day and night these days to let them have no time to rest, I would have to do it, and I would have been swaying in front of you." Forensic Doctor Xu joked with Lao Luo. The decades of friendship made their communications feel tacit understanding and comfort in each other.

When he thought of the two live treasures in the group, Lao Luo's face showed a smile, and his depressed mood was relieved a little. He picked up the tea and took a sip. Lao Luo's face became serious again under the light and dark light. He said to the forensic doctor Xu who was sitting down: "Since you are here, let's check the autopsy report again. The deceased Zhang Hua, a male, 55 years old, a director of Wanhua Chemical Group, died in his villa three days ago. According to the description in the autopsy report, he should have inhaled too high concentration of chlorine in a short period of time, resulting in acute poisoning death, but why did not fill in the specific cause of death in the cause of death column in the report?"

Forensic Xu stroked the head in his ear, frowned, and thought for a while before she expressed her concerns: "Old Luo, I don't hide it from you. The reason why I didn't fill in the cause of death column is because I found that the cause of death of the deceased is contrary to common sense. You know that filling in the forensic report on the cause of death is a prudent and cautious thing for every forensic practitioner who is engaged in the forensic report. Once it is filled in incorrectly, this is not only irresponsible for our investigation, but also irresponsible for every dead life."

"Old Luo, based on my years of forensic experience, the body you sent three days ago is really incredible. After my dissection, I found that there were a lot of white and pink foam phlegm in the throat of the deceased. The upper respiratory tract of the deceased showed mucosal inflammatory congestion and necrosis of the deceased's upper respiratory tract, and the respiratory trachea of ​​the deceased also suffered varying degrees of damage. These characteristics are manifestations of chlorine poisoning in the deceased. In addition to these physical symptoms, I also found that the deceased's respiratory tract had different degrees of chemical burns. His face was purple and blue, his conjunctiva bleeding in the eyes, and there were signs of hydrogen sulfide poisoning on the body. To sum up, the deceased was forced to consume different kinds of toxic gases during his lifetime."

"After the autopsy, I did an x-ray on the deceased's chest in the laboratory. According to the x-ray diagram, I found that the chest of the deceased has a large flake-like shadow with uniform density, or a flake-like shadow with different sizes and density, and a blurred edge, which is widely distributed in the fields of both lungs, and a small number is butterfly wings. This shows that the lungs of the deceased are mainly extensive, diffuse pneumonia or alveolar pulmonary edema. The autopsy materials I mentioned above all talk about acute poisoning symptoms caused by toxic gases."

"Then what I want to talk about is really contrary to common sense. When I checked the corpse, the bones of the deceased were found, and the content of heavy metals in the fat and liver was far higher than that of ordinary people. I have only seen this high content in a person who has lived in a severe heavy metal pollution for a long time. They have experienced lesions of varying degrees of their bodies, such as abnormal bone growth, bone pain and cancer, etc. This is really incredible to a director of a chemical company.

What’s going on, don’t he know the harm of excessive heavy metals in his body? What’s even more bizarre is that I later transferred the physical examination file of the deceased in the city hospital. The deceased went to the city hospital for a full-body examination in April this year. The examination results showed on his medical record that he was very healthy in addition to a little hypertension and fatty liver. In just one month, a healthy person became a patient who suffered from heavy metal contamination for a long time and caused physical failure? This is obviously not in common sense."

In the dark, Lao Luo had no expression on his face, holding a pen in one hand and poked the tabletop, making a regular "demon" sound. After hearing the words of Forensic Xu, he nodded with agreement and said: "And according to the visits of our colleagues and the surveillance videos in the city during this period, Zhang Hua obviously had not been in a heavy metal pollution environment during this period. Even the chemical factory he invested in had not taken a step forward. So what exactly caused his series of poisoning situations?"

"I don't know. From the perspective of our forensic doctor, I can't give you advice this time. After all, I have never encountered this situation." Forensic doctor Xu shook his head and said that even after the corpse's dissection, she was at a loss for this mixed toxic gas. Generally speaking, some toxic gases will react chemically when mixed together, but from the perspective of the corpse, this is not the case. Could it be that the murderer repeatedly brutes the corpse, and this is a retaliatory crime?

"Tick tick tick..." The sound of the alarm clock moving in the discussion room echoed empty in the quiet city bureau building. Team leader Luo and Forensic Xu sat on the chair and thought deeply. The case was full of doubts, and there were too many places that needed to be investigated. The police did not find a fingerprint except the deceased at the scene, there was no suspicious head, and there was no trace of someone breaking into the villa from outside. Could it be that the investigators could not judge whether the murderer existed or not? But the death was seen from the scene.

There were indeed signs of struggle before the death of the man. If there was no murderer, why did he take such a painful way to kill himself? Why did a box of sleeping pills solve the problem so tragic (the skin of the deceased's body was ulcerated at that time, and the death was extremely disgusting)? And why did the police officer Chu, who was sent to assist in the investigation during the day, insist that this was a murder case? What was the small balcony railing he pointed out in the villa area that was burned by chemical drugs?

Team Leader Luo rubbed his head hard, and the more he thought about it, the more he became more confused, and he seemed to have no idea. After explaining to the Forensic Xu, Team Leader Luo leaned against the window and took out a pack of Liqun and smoked it, and lit it with a lighter. The faint Mars ignited a thin column of smoke, and the small light made Team Leader Luo's face light and dark. The ashes drifted, and the neon lights at night and the Mars at his mouth were all reflected in Team Leader Luo's eyes. The faint thoughts were like floating.

The long and endless algae cluster in the deep sea is unknown, and the neon lights in the distance are like the eyes of clowns. The clown's eyes blink, and meaningless songs penetrate into the mind of Team Leader Luo: "Neon lights, neon lights, old man's big boom, clown's headlights. Hohoho, little old man, big and small clown. Who wants this old and stupid big boom, who wants this stupid and stupid clown. The bright and beautiful headlights, the old man full of honor.
