13. In-depth analysis
First of all, the murder weapon in the "Seven Knives Case" was a 24-centimeter-long watermelon knife, which was casually thrown next to the corpse, and no fingerprints were extracted, but there was still a black L-size women's windbreaker left at the scene, which could not be the deceased from the size and style. The belongings of the deceased were not present at the scene, so their identity is unknown.
That trench coat was supposed to be the murderer's belongings.
In addition, no useful fingerprints were recovered at the scene of the "burning case", but the bag containing the victim's identity document was thrown not far from the body, saving the police a lot of time.
The police found the deceased Luo Bofan's house according to the address on the document, and took his usual toothbrush for DNA comparison, and the results matched.
Therefore, from the analysis of environmental evidence and traces, it seems that the two cases are really independent and unrelated to each other.
The more I thought about it, the more strange I felt that the murderer of the "burning case" was so strange, if he took the victim's bag away, and only with a charred bone in the oil drum like charcoal, the police could only temporarily put it on hold as an unsolved case, and it would not be until it was connected with the missing person to find out the identity of the deceased.
If you think about it, you really can't rule it out. As for why the murderer did this, it will have to wait for the deceased's background check report to come out before it can be analyzed.
The murderer of the "fire case" may have been a tall and strong man, because there was a recent physical examination report of the deceased in that leather bag, which was clearly written, with a height of 178 cm and a weight of 120 kg, which was considered a sturdy big fat man.
It is not easy for a woman to get such a heavy fat man to be burned to death on the river beach, which is full of large and small piles of rocks, and the car cannot drive through, so it can only be carried or carried. More than 1,000 meters of paved rocky road, if I were to carry him along, I might not be able to do it.
But there is a women's windbreaker at the scene of the "Seven Knives Case", since the size is not the victim's, it should be the murderer who fell there, then the murderer should be a woman and have a good figure.
These two points do not fit.
Although the more you analyze, the greater the difference, it seems that the two cases are not the same murderer at all.
But I gradually seemed to sort out a clue and found something.
It is true that there is no clear commonality at the scene of the two cases, but they have a more "vague" or "less obvious" commonality.
It is that the murderers in both places seem to be very careless, leaving many traces, and at first glance it seems that two inexperienced novices committed crimes in a panic.
For example, there are murder weapons in the "Seven Knives Case", as well as coats left by suspected murderers; The "fire case" contained the identity documents of the deceased, and the address and telephone number of a chemical plant were printed on the oil drums containing the bones.
But is that really the case? Is it really a crime committed by a novice in a panic? Is it necessary for a panicked person to carry a fat man of more than 200 catties to the river beach and burn it? Wouldn't it be clean to stab to death with a knife or beaten to death with a stick? There are many ways to kill people in this world that are simpler, less laborious, or more relieving than carrying people to the beach and burning them to a charred mass.
Also, can a panicked person stab a woman seven times in a row without being fatal, and let her lose too much blood and die slowly?
The reverse reasoning is the same, a person who has the patience and perseverance to get a fat man of more than 200 pounds to the river beach and burn it to death......
Wait a minute.
I seem to be a little confused and preconceived, who said that the fat man of more than 200 pounds must have been carried to the river beach by the murderer? It's entirely possible that he went on his own, didn't he?
What if the murderer asked him to go there to talk about things, knocked him unconscious while he was unprepared, and then threw him in an oil drum and burned it?
Why did you paranoidly believe that the murderer had turned his back before? Because the victims of the "Seven Knives Case" were tied to death with hemp rope, and my subconscious mind had already seen them as serial cases, thinking that the victims of the "Fire Case" were also tied before they died, so I analyzed it smoothly all the way but forgot the most fundamental things.
After realizing this, I quickly went back to look for the post-mortem report in the "fire case" file.
One of the most frustrating things in the world is looking at the autopsy report, all kinds of professional symbols, all kinds of technical terms, several numbers and letters.
Fortunately, the last two pages contain a concise description: the body had a dislocated right arm and a mild fracture in the skull caused three days before death.
That's right, it shows that my previous analysis of the road is not too biased, and it is very likely that the deceased Luo Bofan was forcibly carried to the river beach.
Moreover, he was tortured before his death, which is the same as the victim of the "Seven Knives Case".
The body of the woman whose hands and feet were tied had not only the wounds from the hemp rope, but also the injuries caused by the beatings she had suffered before her death, indicating that the killer had abused her before killing her.
One of the two victims was stabbed seven times when he was conscious, and he watched his life pass by little by little. The other was burned alive. It's all miserable. And this word "miserable" is also a common denominator I am looking for.
The facts of the case seem to be getting a little clearer. The next step is to profile the suspect, which has always been a favorite step for me because it involves all aspects of psychology.
I think people who understand psychology are mysterious and have an incredible power, such as Zhuang Jing.
Zhuang Jing is a friend of mine and an expert in psychology.
She knows hypnotism.
I once saw her hypnotize more than a dozen policemen, including Bai Yafeng and Liu Yimin, at the same time, and I was stunned and convinced.
She asked me if I wanted to try it. I didn't dare. Although she said that I was not the kind of person who was easily hypnotized, and that it was only a small hypnotic side test, I still didn't dare.
My proposal to Zhuang Jing is not an ordinary rejection of being hypnotized, but a deep fear that the situation may be out of his control after being hypnotized.
It seems that I haven't been in contact with Zhuang Jing for a long time, and I don't know if she is okay.
I left the conference room to go to the bathroom, went to the police hall on the first floor to ask a few more detailed questions related to the two cases at hand, then made a cup of tea, and stared at the clock against the wall to drink slowly, still analyzing the case in my head.
was in a trance, suddenly heard the chaotic footsteps coming from the gate, quickly turned around and looked, it was Liu Yimin, followed by seven or eight people, it seemed that several people were closing at the same time, Bai Yafeng and they should also come back together.
But after waiting for a while, Bai Yafeng didn't come in, so he asked Liu Yimin what was going on.
Liu Yimin said: "The construction worker attacked the police and resisted arrest, but fortunately, the people sent to support him arrived in time. ”
I was startled and asked him, "Is anyone hurt?" ”
He said: "Wang Dongsheng was beaten, but fortunately it was not very serious, and now the suspect has been subdued on the way back." ”
I instantly felt sorry for Wang Dongsheng, if I hadn't sent him WeChat, he might not have gone in person, and he wouldn't have to take a beat.
But on the other hand, if you go to another person, the situation may be worse or not, I have seen Wang Dongsheng deal with emergencies, especially powerful.
I followed Liu Yimin upstairs in a hurry and asked him how the investigation was going.
"It's not a big gain, but it's not nothing," he said. ”
While answering my question, Liu Yimin instructed the people behind him to hand over the materials to the police on duty, and then all of them were dismissed, went home to eat and sleep, and asked everyone to return to the bureau tomorrow afternoon.
After the order, he turned back to me and explained to me that everyone hadn't closed their eyes for two days and two nights, and that the police were also human beings, and they had to eat and sleep.
I grinned and said, "You seem to be human too, why don't you leave?" ”
He said: "I'll leave after I sort out all the materials for today's investigation and hand them over to you." ”
As he spoke, he snatched the unfinished half cup of tea from my hand and swallowed it in one gulp.
I followed Liu Yimin to his office on the second floor, and found Hu Hailian hiding in it to sleep, holding her mobile phone in her arms, frowning her eyebrows, sleeping very well, looking like she was recovering from the corpse at any time, and couldn't help laughing, thinking that she would really be able to find a place.
I didn't want to wake her up, so I gestured to Liu Yimin, meaning that I would go to the first floor and wait for the information.
He nodded, ignoring me.
When I went downstairs, I happened to meet Bai Yafeng and a group of people coming back, and they were all making a fuss.
The construction worker was handcuffed and escorted to the interrogation room, Bai Yafeng didn't have time to talk to me because he still had a lot of formalities to do, so he just desperately squeezed his eyebrows at me, opened his teeth and claws, and had 10,000 meanings to express, but I didn't understand any of them.
I didn't want to pay attention to Bai Yafeng, so I only dragged another policeman who went out with them and asked Wang Dongsheng how he was, if he was seriously injured.
The answer was that it was not heavy, only a little bit of skin, and it was nothing.
I don't have to worry about it, this case is very clear before and after, just wait for the suspect to admit guilt, or the identification reports of the physical evidence from the forensic department come out, and it can be closed.
I walked to the first floor and waited for Liu Yimin to return the background materials of the deceased in the "fire case" that they had investigated today, and overheard two policemen on duty gossiping with their heads on their heads, saying that Deputy Captain Yan's order had come down, and he would report directly to the provincial department after returning from the study.
I was taken aback by the news.
I know that Deputy Captain Yan went to Beijing to study criminal psychology, and he called me before he left, and we talked for a while, but I really didn't hear the slightest news about his transfer, until now.
The two policemen didn't notice that I was listening, and they still bumped into each other and muttered about Deputy Captain Yan's transfer, which was probably true.
It turned out that Bai Yafeng was jumping and shouting at first glance, saying that as long as he solved a big case, he could be promoted to vice captain, and the matter was not completely groundless.
But I think, why can't it be Yafeng's turn, there are several people in front of him who are hundreds of times better than him in all aspects.
