Lu Chuan had inspected corpses in the water several times and was no stranger to this kind of work.
But in the past few times, the corpse was in a relatively intact state. It had been soaked in water for a few days at most. Although the edema was severe, at least the general appearance of the corpse could be seen.
This time the body was different. The dismembered body had been in the suitcase for who knows how long.
The chain outside has completely rusted, and there is still mud and sand brought up from the river bottom on it. Among the mottled spots, pieces of rust have fallen off.
Lu Chuan’s first investigation target was the chain locking the box.
The iron chain made of pure iron is tied to the box in a cross pattern. It is not locked, but is locked by rivets.
Lu Chuan wanted to have the intermediate spot survey skills in hand, which involved judging the rusting of iron tools in water.
The morphological changes of ironware in water are mainly judged by the degree of corrosion, and then the length of time the ironware exists in the water can be obtained.
I just communicated with Wang Changjiang. The forensic doctor wants to more accurately determine the time of death through the corpse. There is a high probability that it can only be determined through the analysis of the skeleton, but relatively speaking, it is not accurate enough.
Lu Chuan is probably better than the forensic doctors at the scene when it comes to skeletal identification. Although he can determine the age of the deceased through the bones, he cannot accurately determine the specific death of the deceased if he cannot combine the identity of the deceased. of time.
Now, the degree of corrosion of iron chains in water can be used as an auxiliary basis for judgment.
"Corrosion iron filings fall off...yellowish brown...the average corrosion depth is 0.3 mm..."
The degree of corrosion of iron must be judged based on the water quality. Different water quality has different acidity and alkalinity. , which will lead to subtle differences in the corrosion of iron in different waters even within the same period of time.
The five boxes are all about the same size, but the styles are different. Investigate the brands of the boxes...
It is unlikely.
Lu Chuan just took notes.
Opening the box, there was a partially liquefied corpse inside.
The limbs were dismembered into eight pieces, the torso was broken from the middle, and divided into four pieces horizontally, without a head.
Because most of the corpse has been liquefied, the gender cannot be determined from the external characteristics, but the bones are slender, so it is more likely to be female.
Lu Chuan put on five layers of rubber gloves this time and reached out to fish out the body parts from the box piece by piece. After looking at each piece, he handed it over to the forensic team behind.
Lu Chuan looked at every piece of corpse very carefully. There were twelve pieces of corpse in total. It took Lu Chuan ten minutes to take them out one by one from the box.
"Female, 1.62 meters tall, 26 years old, wears high heels for a long time, has a comminuted fracture in her right hand...most likely engaged in massage or other jobs."
Huh?
Sun Jian, who received one of the thigh bones, was slightly startled. Did the victim have any massage or other work?
What's going on?
How can you tell?
Across the province, Sun Jian, as Zhang Yuanchao’s apprentice, should be ranked in the first echelon in terms of strength in the forensic team. To put it bluntly, he should even be in the top five. the existence of names.
For so many years of work, I have dissected hundreds of corpses and accumulated a lot of experience.
Every time Lu Chuan observed a piece of corpse, Sun Jian was also observing it.
Except for the lack of a head, the body in the box was completely intact. Although it was severely decayed, it was relatively easy to determine the gender and height of the body through these body parts.
As for comminuted fractures, when Sun Jian first came into contact with the bones, he also discovered that as a forensic doctor, it is a basic skill to judge the condition of the deceased based on the corpse.
However, the age judgment...
Twenty-six years old... This is very accurate. The corpse was badly decomposed and there was no head. It was impossible to judge the age by the condition of the teeth. Lu Chuan directly came up with such accuracy. The conclusion...
To be honest, Sun Jian found it very difficult.
But Sun Jian knew about Lu Chuan. Not only did he know about it, but he knew it very well.
Last year’s skeleton case in Tianzhou City still has its aftermath. Lu Chuan’s ability in identifying skeletons, not to mention him, even Zhang Yuanchao would give a thumbs up.
But even so, how did Lu Chuan determine that the deceased was most likely engaged in... the massage industry?
"Xiao Lu...the deceased was engaged in the massage industry during his lifetime?"
Sun Jian doesn't need to ask, others don't understand either.
Age, weight, and height don't matter, it's all about experience.
But for massage...
How can you tell?
Wang Changjiang frowned and didn’t understand.
"Hands, the hands of the dead."
Lu Chuan picked up the two forearms on the dissecting table.
The murderer started dismembering the upper limbs from the shoulders, using some kind of saw to cut, and then cut again at the elbows, cutting the upper limbs into two parts.
"The bones of the deceased's hands were relatively thick. Compared with the hands of ordinary women, there were obvious traces of acquired bone edge hyperplasia. This is caused by long-term exertion of the hands, and look here..."
Lu Chuan pointed to the phalanges on his fingers that were partially exposed due to rotting flesh and blood: "The bone at the front of the phalanges is obviously thick. The strength of the fingers of the deceased was much stronger than that of ordinary people during his lifetime."
"If he hadn't deliberately passed through This is unlikely to happen when training with a fingertip gripper.”
Wang Changjiang, Sun Jian and a dozen other forensic doctors looked closely at the corpse with their hands. It was indeed somewhat different from the corpses they usually dissected.
"Of course, what I am talking about is just a matter of probability. The deceased may also be engaged in other jobs where fingers are used more frequently, such as twisting screws in an electronics factory, but it is generally difficult for all ten fingers to be like this. "
Sun Jian had a feeling that his group of forensic doctors could be so effective.
This information should have been identified by the forensic doctor after the flesh and blood were removed from the bones, but Lu Chuan just looked at it and came up with this basic information.
Of course, the specific cause of death is definitely not clear.
Lu Chuan continued to collect the materials in the box and prepared to do some trace evidence analysis to see if he could gain anything.
The first body bag was quickly inspected. Lu Chuan finished organizing the photo information, recorded it, looked at the records, and started testing the second body bag.
According to the order of discovery, Lu Chuan numbered the five body bags sequentially, from one to five.
The time when body bag No. 1 was launched was about half a year ago. The specific time is still uncertain and requires more detailed analysis. However, the corrosion degree of the chain can probably lock in this time period.
The minimum period is half a year and the maximum period is no more than one year.
Body No. 2 was dismembered in a manner similar to that of Body No. 1.
The murderers all violently dismembered them, using some kind of electric saw or chain saw for cutting. There was no trace of ax or knife chopping, just like a slaughterhouse dismembering frozen cattle and sheep. (End of this chapter)
