Chapter 324 The Terrifying Beauty of the Golden Ratio
Detective Squadron Two.
Chen Yan presided over a case analysis meeting.
Zhang Chaoyang is reporting on the preliminary investigation.
"The deceased, Zhang Guicai, male, 48 years old, from Ergong Village, was the owner of the house that caught fire."
On the screen was a photo of the deceased Zhang Guicai.
"This Zhang Guicai served as the head of Ergong Village three years ago, but was later reported by the villagers for misappropriating collective funds."
"Later, although the hole in the collective funds was filled and he was not jailed, his position as village chief was removed."
"I haven't done anything in the past three years. I have been relying on my laurels."
"When the victim was the village chief of Ergong Village, he acted unfairly and made a lot of money on issues such as land leasing and house demolition in the village."
"The reputation in the village was extremely bad. It is said that on the day he was dismissed, many people in the village even set off firecrackers to celebrate."
"Zhang Guicai's wife returned to her parents' home three days ago and has not come back."
"He has two sons, both working in Shen City, and they are both married now."
"Team Chen, this is the basic situation of the victim."
On Chen Yan's way back from Shen City, Zhang Chaoyang had already started conducting background checks on the deceased.
Basic information, already mastered.
According to Chaoyang's investigation results, Zhang Guicai offended many people in the village during his ten years as village chief.
In addition, at the crime scene, Zhang Guicai's limbs were chopped off and his whole body was nailed to the wall. The possibility of a vendetta is very high.
However, Zhang Guicai's house is far away from the houses of other villagers and is a separate house.
Apart from a surveillance camera he installed in front of his home, there was no surveillance nearby.
Moreover, after inspection, it was found that the computer hard drive that saved the surveillance video at Zhang Guicai's home had been removed.
The crime scene had been completely destroyed due to fire fighting, and Chen Yan and others did not collect any valuable clues.
Chen Yan tapped the table lightly and frowned.
There were no fingerprints or shoe prints at the crime scene, and even the blood stains were almost indistinguishable due to the fire and fire sprinklers.
There were only corpses nailed to the wall.
On the surface, it seems that there must be no clues.
Even if Chen Yan turned on the visual gene lock, there wouldn't be much doubt about it.
However, there is no doubt, which is actually the biggest doubt.
Judging from the situation at the scene, the fire was deliberately set by the murderer.
Firefighters discovered the plastic insulation that had been stripped from the electrical circuits in the kitchen where the fire started.
It is precisely because the insulation of the circuit is damaged that fires occur.
Moreover, the murderer did not deliberately hide it.
Because the other party also tore off a piece of wire and put it on the woodpile.
This is to ensure that if the circuit catches fire, it can ignite the pyre.
The body of the deceased had its limbs chopped off and then nailed back to the wall.
Judging from the traces of the deceased's wound, the other party's knife was very stable.
There were no scratches on the severed limbs at the joints, they were all chopped off with one knife.
The same goes for wrists, ankles, elbow joints, and knee joints.
After the other party cut off the limbs of the deceased, they re-nailed the trunk and limbs to the wall according to the enlarged proportions.
And the distance between each joint is accurately measured.
According to the measurement, each gap is two to five centimeters, which is very precise.
The direct cause of death of the deceased was death from shock after massive hemorrhage.
Standing up, Chen Yan walked to the whiteboard and began to arrange the investigation tasks.
"First, visit and investigate Zhang Guicai's relationship network."
"From what we have learned so far, Zhang Guicai, during his tenure as village chief, disregarded the collective interests of the village for his own benefit, which must have directly or indirectly harmed the interests of the villagers."
"Check, find out what Zhang Guicai has done in the village these years, who he has interests in, and who he has enemies with. No one is left behind."
"Chaoyang, you are responsible for this matter."
"yes!"
"Second, based on the preliminary judgment of the injuries on Zhang Guicai's body, the murderer is likely to be a patient with obsessive-compulsive disorder and a person who pursues perfectionism."
Although the murderer left no traces of himself at the scene, the body itself is the most important clue.
"Look, everyone," Chen Yan turned on the projector, which showed a photo of Zhang Guicai's corpse.
"The victim's limbs were chopped off. Judging from the knife marks at the stubble, every joint was severed by a knife, and no bones were injured at all."
What does this mean?
"This shows that the murderer's profession must be very understanding of the structure of the human body."
The joints of the human body are connected through ligaments and muscles.
There is cartilage tissue between bones, but the cartilage tissue is not in direct contact.
Within each joint, there is a closed space formed by muscles and ligaments.
There is tissue fluid inside, which acts as a buffer and lubrication.
"Only people who are very familiar with the structure of joints can use a sharp knife to cut through the muscles and ligaments around the joints."
"Complete the cut without damaging the bone."
Otherwise, if you cannot find a trick for a joint, especially the knee joint, elbow joint, etc., it may not be possible to cut it open with more than a dozen cuts.
"Also, everyone, look at the distance between each limb."
Chen Yanjian enlarged the photo and compared it with others.
"After the murderer dismembered the victim, there was a gap of two to five centimeters between each joint."
"This was a gap intentionally left by the murderer and measured with a ruler."
Three photos were enlarged.
"This is a photo of the wall after the left calf and right upper arm were removed."
"Everyone, look here," everyone held their breath and looked carefully, there were two nail marks.
"There are two traces of nail gun shooting here."
"We tested it and found that if the arm is placed according to another nail mark, the distance between this upper arm and the lower arm will become 4.8 cm."
"2 mm!"
Chen Yan stuck his thumb and index finger together to compare the 2 mm gap.
"Normally, this distance is difficult to detect with the naked eye."
"But the other party re-fixed the limbs because of these two millimeters."
"There is also two nail gun marks on the left calf on the wall. The measured distance is 3 cm, and the distance error between the two nail marks is 3 mm."
"In addition!"
Chen Yan took a half step back and switched the photo again.
It was a photo of the front wall where the body was nailed.
"Everyone, look at the wall where the murderer fixed the victim's body."
Chen Yan discovered this at the scene.
The position of the body in the front has a thrilling sense of comfort.
That's where the body is nailed.
Up and down, left and right, every place looks very comfortable.
It seems that any position moving half a point is wrong.
"Everyone, look at the position of the head and feet of the body."
"The distance between the ground and the ceiling of the arm joints and leg joints."
"And the position of the whole body in the wall, and the distance from the two ends of the wall."
As Chen Yan spoke, red distance lines appeared on the projected photo.
Mark out all the distances that Chen Yan just mentioned.
The center point of the body is 3.5 meters away from the window, that is, the south end of the wall.
The distance from the other side to the north end of the wall is 5.66 meters!
"Look at the center point of the arm joint, the distance from the ceiling is 0.9 meters, and the distance from the ground is 1.46 meters."
"And the center point of the thigh knee joint gap is 0.9 meters from the ground, and the distance from the ceiling is 1.46 meters!"
Chen Yan looked at everyone: "Do you know what this means?"
Wang Gang scratched his head: "Captain, do you mean the wall is 9.16 meters long and 2.36 meters high?"
Chen Yan: "..."
Okay, you are right.
"Besides this?"
As soon as Chen Yan finished speaking, a very small voice came from the conference room.
"Captain Chen...do you mean...the golden ratio..."
