Corpse No. 2 is a male corpse, 43 years old, 1.78 meters tall, left-handed. Judging from the corrosion of the chain, the murderer dumped the body about a year ago, within a year and a half. Lu Chuan still needs to do some work at the specific time. Only experiment can determine.
As for the conclusion of being left-handed, Lu Chuan does not need to explain. Sun Jian and others are not just eating dry food. The left hand of Corpse No. 2 is obviously thicker than the right hand, which is exactly the opposite of the situation of ordinary people.
The size of adult hands is different. This is not caused by congenital formation, but by acquired development due to the different frequency of use of the two hands.
The vast majority of people are right-handed. In daily life, the bone gap of the right hand is wider than that of the left hand.
If the opposite situation occurs, there is a high probability that it is left-handed.
Because the corpse is soaked in water for longer, the degree of liquefaction of the corpse is greater, and the smell is stronger.
As the investigation and forensic work continues, other members of the crime team are not idle either.
The most important thing for this old case is to determine the source of the body.
Only by confirming the identity of the body can we proceed to the next step.
After the five body bags were discovered, every time Lu Chuan gave the basic data of each body, the crime team would first conduct an investigation within the scope of the missing persons.
The identity of Corpse No. 1 soon became highly probable.
“Eight months ago, we received a missing person report. Su Mo, female, 1.62 meters tall, 26 years old, from Haizhou City, works at Haolai Massage Club.”
Wang Song quickly identified the target in the missing persons information database.
Under normal circumstances, there is a high probability that the age and height of a missing person have unique attributes. As long as these two pieces of information are available, as long as the other party reports missing, there is a high probability that the information will be found.
Anatomy room.
"Confirmed, the identity of No. 1 is Su Mo, the masseuse who disappeared eight months ago and is here again."
Sun Jian looked at the body bag of No. 5 with complicated eyes and continued to do the spot survey. Lu Chuan.
What the hell, this is the gap.
People can get so much information after just one look. Forensic doctors like myself...
These days, it is said that the one who defeats you is not your peers, but most likely someone from across the border.
Unexpectedly, the forensic field also fits this rule.
"Brother Sun, help me, this chain is new, don't mess with it."
Five body bags, the other four No. 1 corpses have now determined the time of death, eight Months ago, corpse No. 2 was a year ago, within a year and a half, and corpse No. 3 was a long time ago, five years ago, but not more than ten years ago.
The longer the time, the lower the accuracy of judgment. The body bag No. 4 that has been soaked in water for the longest time has been more than ten years.
The latest one is body bag No. 5. The chains are not rusty yet, probably only a month or two ago.
The information was continuously summarized to Li Donglin, and every piece of information made Li Donglin think more deeply.
The murderer committed the crime over a long period of time.
Ten years!
And the other party's methods and techniques of dismembering corpses seem to have been improving.
On Corpse No. 3, only the torso had marks cut by a saw, but the limbs were chopped off with an axe.
The longest corpse, No. 4, had no traces of saw cutting at all, and was all dismembered by axe.
Obviously, the other party's killing methods are gradually evolving, and their methods are becoming more and more sophisticated.
This kind of criminal suspect is the last thing the police want to encounter, because they have committed many crimes and passively accumulated a lot of experience, and they are growth-type criminal suspects.
It was easy to determine the identity of corpse No. 1, but the progress of the subsequent four corpses was very unsatisfactory.
"The murderer probably did not kill in one place, and if he killed so many people in one place, he would have been discovered long ago, right?" The person who spoke was the forensic doctor of the Liangzhou City Criminal Investigation Detachment. middle-aged man with bright eyes and bald head.
"I also think that this guy killed five people... No, he killed at least five people. He is definitely a pervert."
"Do you think the murderer lives near here? Otherwise, why were the five corpses dumped here? "
This question...
Lu Chuan nodded in his heart. The five body bags were all found in the same river section, and The time span exceeds ten years, which means that the murderer most likely lives nearby and is used to abandoning corpses here.
Moreover, if it were not for the construction of a hydropower station on the Wangjiahe River and the interception of water, which caused the water level to drop, these corpses would not have been discovered at all.
Perhaps, this is an unsolved case that will remain unsolved for a century.
If Wangjiahe is not dried up and the body cannot be found, of course the murderer will remain at large.
Maybe he will continue to kill people and then quietly come back here to dump the bodies.
“The place where the murderer dumped his body was in the deep water area of the Wangjia River. The water flow is very fast. Usually fishermen don’t come here. This is definitely a place carefully chosen by the other party.”
"Well, no one has discovered it for more than ten years. If I were the murderer, I would choose to continue dumping the body here."
While boiling the bones to separate the flesh and bones, the forensic doctors discussed the direction in which the case would develop.
When the fifth body bag was untied, the condition of the body inside gave the forensic doctors a lot of comfort.
The body was in very good condition. Although the swelling was extremely severe, it was not rotten.
The fatal injuries were also very obvious. He was stabbed in the back and stabbed continuously, which eventually led to the death of the deceased.
This made Lu Chuan more excited. The stab wound on the back could not only determine the cause of death of the deceased, but also analyze some information about the murderer.
"Killing someone behind the back shows that the deceased was most likely unprepared for the murderer, and the two probably knew each other."
Sun Jian only took one look at the wound and gave his own judgment.
Other forensic doctors also nodded. This is common sense in probability.
The murderer has a motive in most cases. There are random killings, but they are rare in China.
Judging from everyone’s knowledge and experience over the years, the murder behind the scenes was most likely the result of a sneak attack by an acquaintance.
"The deceased was a male, 1.82 meters tall...The height of the wound was three centimeters below the back of the heart, and the entrance of the knife wound..."
Lu Chuan opened the wound and carefully observed the shape of the wound. The wound was swollen and deformed due to being soaked in river water, but the direction of the wound could still be determined.
"Stab diagonally downwards. The murderer should be lying on the knife with both hands, from top to bottom. At this distance..."
Lu Chuan analyzed and made actions again and again.
Raise your upper hand high above your head, make a fist and thrust downward.
"It's just an angle!"
"Combined with the height of the deceased...the murderer's height is most likely 1.73 meters...all between 1.8 meters, very strong, adult male . "
This data...
Sun Jian and others looked at each other, this is a bit mysterious.
Of course, everyone knows the truth behind this. Based on the inclination angle of the wound and the height of the deceased, if you want to leave such a scar, you can roughly calculate the height range of the murderer.
However, if it is theoretically possible, how to calculate it specifically?
We are forensic doctors, not mathematicians. (End of this chapter)
