The head of the deceased was cut from the middle of the neck - to be precise, and although the body had decomposed, and the incision was so swollen and decomposed that no trace of the axe could be seen, there were two other scar marks on the cervical vertebrae of the deceased, and the knife - or axe - was obstructed at the cervical vertebrae when the murderer removed the deceased's head. The first cut is 0.3 cm from the incision, and the second is 0.5 cm from the incision. This means that the killer slashed at least three times before cutting off the deceased's head.

The body of the corpse has two iron wires, the iron wire is a thin iron wire, the first iron wire is at the chest, the iron wire is wrapped around a total of nine times, the second iron wire is five or six centimeters above the knee, the iron wire is wrapped around a total of seven ways, and on the two iron wires also fell two city wall bricks, the two city wall bricks are tied separately with iron wire, and then connected with the iron wire on the body, the connection place is on the back of the deceased, when the worker gets the body up, the face of the body is facing up (the iron wire on the city bricks and the iron wire on the body belong to a model).

After untying the wire, there were two strangulation marks about one centimeter deep on the body of the corpse (the corpse was more swollen).

There were no other wounds on the body, and the source of death should be the head of the deceased, where is the head?

Why did the murderer cut off the head of the deceased and hide it somewhere else? Is it to vent hatred, or to hide the evidence? We all know that the so-called "headless case" is a case without clues. The identity of the deceased is mainly based on the five senses of the person, and there are some features on the human body, but due to the wrapping and covering of clothing, other features other than the five senses are generally not known to the people - or not known to the people, and some physical features can only be known to those who are close to them.

It's like looking for a needle in a haystack.

The first step is to confirm the identity of the deceased, and the second step is to find the murderer,

Who is the deceased? Neither Ouyang Ping's initial investigation nor Chen Jie's subsequent investigation took this step.

Let's take another look at the account of the dredging workers (there were five workers involved in the dredging, and the dredging tools were cement boats and silt pumps. Because the underwater sludge is deposited for too long, the dredging work is divided into two stages: the first stage is to use a silt pump to pump the underwater silt onto the cement boat; The second step is to drain the river water in sections and manually clean up the remaining bottom silt).

When the workers were pumping the underwater silt with the sludge pump, the sludge pump suddenly only worked out of the silt, and the suction port of the sludge pump must have been blocked by something, so the two workers went down to the water and touched the suction port along the rubber pipe of the silt pump. Worker Liu Zhiqiang was the first to touch the suction port, and the suction port of the sludge pump was really blocked by a foreign object, so he squatted into the water (only the head was exposed to the water, and the water depth of the rubber tube suction port was sixty or seventy centimeters), trying to take out the foreign body blocking the suction port, and when his right hand touched the foreign body, he instinctively retracted it. What his hand caught was a soft, slimy Dongsi, which he thought was a very special fish.

Worker Li Wenqing from Liu Zhiqiang's actions. There was an abnormality in his eyes and expression: "Lao Liu, what's wrong with you?" ”

"The suction mouth is indeed blocked by something, like a fish."

"A fish? Then why did you let go? ”

"It's soft, it's sticky. It seems to be stuck in the suction mouth. ”
