Dirty river flowing through the lower streets of Tokyo.The banks of the river were reinforced with cement.The houses crowded on both sides of the river were low and dilapidated.The windows of the houses were mostly closed to prevent the stench from the river from entering.The surface of the water, which seemed to be completely still, had turned turbid green, the bottom of the river was piled with mud, and all kinds of garbage were floating on the surface of the water. Empty bottles, various empty packaging boxes, food residues, broken umbrellas, dolls, toys, small animal corpses, sandals on the list, plastic products, etc. These rich types of floating objects have long lost their life and functions, floating freely. On the water, it's like the city's excrement.

Gas-like bubbles emerged from under the excrement, causing some small ripples.After all, the water was still flowing, which somewhat relieved the stench.The water quality inspection of this river is carried out by Yoshio Chinen, Tokyo Metropolitan Pollution Control Commissioner. In order to deal with the pollution problem in Tokyo Bay (mainly caused by the overnutrition caused by nitrogen, phosphorus and other nutrient salts), a liaison committee was formed by the prefectures, counties, and cities on the Gulf Coast, and the Department of the Environment took the lead to establish the "Tokyo Bay Over-Nutrition Liaison Meeting on Nutritization Countermeasures".As part of investigation and governance, regular and fixed-point water quality inspections should be carried out on some rivers.

This river belongs to the water area that Chinen is in charge of. Four times a day, Chinen will conduct water quality inspections at a specific measurement location (under the bridge) in accordance with the Water Pollution Prevention Law. The measurement items include living environment items such as PH or BOD (biochemical oxygen demand) and health items such as cyanide content. Although the removal of synthetic detergents, the culprit of pollution, has never stopped, the improvement of COD (chemical oxygen demand) or BOD water quality is still not going smoothly, so we are strengthening the main pollution source - general family life. In addition to water treatment, it is necessary to actively promote the use of phosphorus-free detergents and strengthen the water quality monitoring system.

These measures and efforts seem to have achieved initial results. Recently, the river water has finally become clearer, but it is still far from reaching the state where the aquatic organisms can reappear. In terms of domestic drainage, through the appeal of the county and the city, although it has been improved to a considerable extent, there are still many people who use the river as a garbage dump and throw all kinds of things into it, making Chinen's hard work come to naught. . Recently, while checking the water quality, Chinen also started a strange recording work.This is what records floating objects in the water.Although this is a small river squeezed between the two banks of the lower street, the abundance of things thrown into the river is enough to show the social level of the residents in this area and their normal life.

First of all, there are a lot of food packaging boxes and residues, which shows that the river is closely related to the daily life of residents.In addition, the main content of the floating object varies according to the change of the season.Generally, from early spring to early summer, there will be more carcasses of small animals.There is more food in summer, and toys are more eye-catching in winter.Generally speaking, there are more summers than winters, and more weekends and month-ends than normal days. As long as he sees the eyes, Chinen will use the net to pick them up, although it cannot be finished no matter what.My own job is to check the water quality, and I don't take on the job of cleaning the river. I just do this because I feel that "my river" seems to be treated as a garbage dump, and I feel uncomfortable.

Chinen fantasizes about the colorful carps swimming and playing in this river, while checking the water quality and taking notes on the floating objects.He thought that when the river became a clear and beautiful river again, the record of floating objects would definitely become a precious piece of historical data. On this day, as soon as the regular and fixed-point measurements were completed, Chinen began to record the floating objects.Because it is both the end of the month and the weekend, there are a lot more floaters than usual today. Vegetable leaves, apples, empty cosmetic bottles, wood chips, plastic bags, plastic products, Styrofoam boxes, dead animals—maybe cats, or dogs.In order to confirm the type of animal, Chinen, who was observing intently, suddenly let out a scream.The corpse of this little animal looks exactly like a human fetus!

No, impossible.Or a pig or a monkey?Is there such an animal down the street?The more you observe Zhinian attentively, the more you feel that this is a human fetus.It has a head and small hands and feet. "It must be my illusion." Chinen shook his head.But no matter how you look at it.Because the distance is too far, the net can't reach there.He stopped the young man who looked like a salesman with a briefcase in his right hand who occasionally passed by. "I'm sorry. What do you think of that dead animal thing floating there?" Asked suddenly, the young man looked in the direction of Chinen's finger in bewilderment.

"Boisterous and disgusting. Like Piggy." "Pig? Does it look like a pig to you?" "Wait. It can't be a dead baby. How could a dead baby be thrown into the river?" The man dressed as a salesman was dubious. "There are exactly five fingers. It must be a human fetus. Please, take a look here. I will inform the police." "I have something urgent to do." "There are human corpses floating there. How can you forget about it!" The young man seemed to be overwhelmed by Chinen's tough attitude, and stood helplessly on the shore.

Although the water seems to be stagnant, it is actually flowing slightly, so if you don't look at it, you may disappear.Chinen pulls the police from the nearby police station. "Didn't you mistake cats and dogs for babies?" The police were brought in dubiously.When I went to the scene, the salesman-like man and the fetus in the river disappeared. "Where is there such a thing as you said?" The policeman had a reproachful look in his eyes, as if to say that if it was a prank, he would never let it go. "It must have flowed downstream." However, both sides of the bank are full of people, and no dead babies can be seen within the sight of the bank.

"Come to the police station." The policeman said unhappily.Chinen inadvertently glanced at the upstream, and couldn't help exclaiming "There!".The fetus had somehow flowed upstream. "How is it? It's a dead baby." Chinen looked triumphant. "It's really similar." The policeman nodded reluctantly.Contact the police station to send a police car to fish out the dead baby from the river. It is confirmed that it is a newborn baby girl. It is probably difficult to handle after birth, so she was thrown into the river. Two years later, late at night, in a back street in Shibuya District, Tokyo, a young man was hit and killed by a car, and the perpetrator escaped.The name of the deceased was Isamu Kasuya, nineteen years old, and he was a hooligan who specialized in soliciting customers for a gangster bar on Kabuki Street in Shinjuku District.

It was the girl who happened to be present who called 119.When the ambulance came, he was dead.The skull was shattered, internal organs and feet were injured, and he was estimated to have died at the scene.On the part of the deceased's calf near the knee, there were traces of a car bumper crash.This indicated that the car was hit without pressing the brakes. I don't know if the perpetrator didn't have time to react, or he hit the car without pressing the brakes on purpose.If it is the latter, it means that the perpetrator has murderous intentions. The deceased, who lived in an apartment near the scene, was probably killed by a car on his way home late at night.The car involved in the accident fled on the spot.An autopsy revealed that the victim's blood alcohol concentration indicated that he was in a state of intoxication at the time.After presuming the time of the crime, it rained heavily at the scene, washing away the evidence of the crime.It can be said that for the prisoner, all the conditions suitable for escape are met. The police took this as a run-and-run incident and began to file a case for investigation, but the prisoner was never found.
