"The remaining things... are too little."
Lu Chuan took the ashes sifted through the sieve and looked at them carefully.
I strongly agree with what Yang Sen said.
But just because there are few things, it doesn’t mean that there can’t be gains.
“The two remaining small bones should be the sole bones and finger bones.”
"These two... unburned teeth?"
Although there were very few remaining bones and they were very small, after careful identification, Lu Chuan was still able to determine which part of the body they belonged to.
Zhang Hui has already finished understanding the general situation of the report.
There are no valuable clues. Among the forest rangers in the surrounding several square kilometers, there is only one person who reported the crime.
Normally no one comes to the mountain, and the rangers only visit once a year.
Moreover, there are many side roads in Beishan. It is impossible to find out where the suspect came up from and when he came up.
There is no human habitation within a few kilometers, so there are no witnesses.
From the action team's point of view, this case is very difficult to detect.
When Zhang Hui saw that Lu Chuan only had two burnt black teeth and two small bones in his hand, his brows furrowed even deeper.
"Lu Chuan, have you found any clues here?"
"There are some clues, but they don't mean much."
"Oh? Tell me first? I'm blind here."
"First, around the crime scene , found some tire marks left by the tricycle. "
"Judging from the depth of the tire marks, the tires of the tricycle are relatively new, and it can be judged that the tires were just purchased not long ago and are not badly worn. "
Of course, for some specific situations, Lu Chuan still has to go back and conduct data analysis on tire marks.
And by comparing some tricycles on the market based on tire pattern patterns, it is possible to confirm the brand of the tricycle.
But this information is tantamount to finding a needle in a haystack. As long as the brand of the tricycle is not a niche brand, it is difficult to narrow down the scope of the criminal suspect.
Besides, the area around Beishan is already sparsely populated. No one knows where the other party came from to dump the corpse and burn it. No one knows how far away it is.
But it’s better to find tire marks than nothing.
At least now we know what tools the other party used to transport the body.
"In addition, the range of the burning of the corpse is probably less than one meter."
Lu Chuan and Zhang Hui gestured at the entire burning range.
“If the other party burned the body directly, the ashes should be in the shape of a human body.”
“But the trace of the burned body on site is a circle with a diameter of less than one meter, indicating that The other party probably dismembered the body and then burned it here."
"So it is basically certain that this place is most likely not the scene of the first crime."
"In addition, the murderer used a combustion accelerant during the process of burning the body."
This is easier to judge.
Because it is impossible for ordinary corpses to burn so fully during the burning process.
Not even a single large bone was left at the scene.
But the exact composition of the combustion accelerant used by the other party is still unknown.
It might be diesel, it might be gasoline or alcohol, etc.
Yang Sen has just collected the soil under the ashes. He will know if he goes back and does some identification and analysis.
“Are there any others?”
“That’s it for now. We will identify the remaining bones later, but the information obtained may not be particularly accurate.”
Although there were only two small bones, the sole of the foot and the finger bone, through some mathematical calculations, Lu Chuan was still able to obtain some body shape information of the victim.
After the two had a rough exchange, Lu Chuan would continue to conduct on-site investigation.
"Brother Yang, bring over the small sieve in the car. I'm going through the ashes."
"Okay, wait for me for a while."
A few minutes later, Lu Chuan held a small sieve with a diameter of ten centimeters in his hand to screen the ashes more carefully.
Yang Sen and others squatted aside and watched.
The main reason why the ashes need to be screened a second time is to see if there are any other finer traces remaining.
This time the screening was not like the one just now, where the three people left the place covered in ashes. Lu Chuan squatted on the ground and gently shook the small sieve in his hand, while the other three people stared inside the sieve.
Focus on meticulousness and not miss any detail.
“Stop!”
Yang Sen's eyes were sharp and he suddenly shouted stop.
Then pick out a very small round bead among the fine ashes.
“What is it?”
“I don’t know, it feels very hard.”
The thing is not big, only two or three millimeters in diameter.
"It looks like iron beads. Take it back for testing."
Lu Chuan continued the screening and soon made another discovery.
“What is this?”
The thing in Lu Chuan’s hand was a nail-shaped object only about half a centimeter long.
Something like a rivet.
"It seems like a bone nail?"
Bone nail?
Speaking Tian Feng.
“My father slipped when he went out this spring and broke his hand.”
“It was time for the hospital to set the bones and put in bone nails. The doctor said they were made of titanium alloy and will heal well. OK, no rejection, just a bit expensive.”
"I saw the sample that the doctor gave me...it seems to be this thing."
"Take it back and compare it with the hospital and you will know."
Several people have been busy working , and then some details were discovered.
For example, button residue that is not completely melted.
There are also some residues of the metal zipper.
In addition, and more importantly, a hook-like item was found.
Lu Chuan didn’t recognize this thing, but Lao Bai did.
"IUD, made of stainless steel, the deceased is a female!"
After most of the day's screening, the on-site investigation has come to an end.
The harvest from current survey is not small.
Two bones and two teeth were found among the ashes of the burned body.
There is also the remains of a stainless steel contraceptive ring.
A tiny iron bead-like residue.
A nail-like object that is probably a bone nail.
A little bit of button residue.
A little zipper residue.
There are many things, but it is still unclear what role they can play.
After the on-site work, Lu Chuan returned to the criminal investigation detachment and carried out related work in full swing.
The first one is about the analysis of two small bones.
Theoretically speaking, the length and size of the human body's bones are in a certain proportion to the height.
Based on the size of each bone, the height of the body can be roughly calculated in turn.
Of course, relatively speaking, longer limb bones such as the tibia and humerus are more accurate in judging height.
But skulls and ribs have disadvantages in this regard.
The remaining bones found at the crime scene were parts of the metacarpal bones and palmar bones.
Relatively speaking, although they are relatively short, they are limb bones after all.
Lu Chuan could probably get some rough information about the height of the deceased.
In addition, regarding the bones, Lu Chuan also discovered a more important clue. (End of this chapter)
