Xu Nanbai showed a very interested expression and continued to listen.
"No matter from the choice of the victim, or the choice of the means and location of the explosion, it all reflects his characteristics. He not only kills the target of the mission, but also kills innocent people. Moreover, there are old and young, male and female, and there is absolutely no necessary connection. He seems to be very arbitrary. He has changed the method of explosion and the location of the explosion many times, which is certainly not required by the organization. He seems to be constantly trying new things, more like he regards all the killings as a game.”
Xu Nanbai nodded intently.
Su Mian continued:
"Second, his age, he should have been around 20-30 years old, he was already an adult. If he is too young, he may not be able to master precise blasting knowledge, and he will not have enough strength to complete the crime; not too big, because if he is old, Now, it has been many years since he committed the crime. Even a pervert should not have such fresh and vigorous energy as him. The modus operandi should also be stable and choose the way he prefers and is most comfortable - but he behaves like a budding Same as explorer. So now, he should be between 25-35 years old.
Third, he was like a child, but a cruel, unsympathetic child. Throwing the victims into the public eye many times and letting them explode to death is not only toying with the victims, but also mocking the public and the police. Furthermore, it is the child's revenge mentality. So, he himself must have suffered some kind of betrayal, suffered psychological trauma.
Fourth, since he has such a mentality, when there are so many cases, I guess he will hide in the crowd, watch the despair and embarrassment of the victims, and secretly complacent. And he hasn't caught him for so long, which shows that he's covering up well. Unattractive appearance, disguised as a college student or ordinary passerby, emotional control and observation must be very strong.
Finally, I think he had the same characteristics as t back then: he was young, his personality was uncertain, and his inner emotions were more intense. In the same way, his loyalty to the organization may also be the highest..."
Having said this, Su Mian smiled slightly, "Maybe when we start the search, he will be the first to jump out and provoke the Black Shield team."
Xu Nanbai smiled even more and nodded, "You analyzed it very well. But there is one more thing, did you miss it?"
Su Mian suddenly became interested, dropped the whiteboard pen and walked up to him, looking at him with his hands behind his back, "What is what?"
Xu Nanbai's lips curled slightly, took a sip of tea, and replied: "Most of the time, criminal psychology is to find evidence from the criminal's 'existing' behavior; but sometimes, it can also be obtained from the 'not' behavior. find it."
Su Mian was stunned, she had never heard of this statement.
Xu Nanbai put down his teacup and continued: "There are so many bombings and so many victims, but they have one thing in common - no child casualties. Once or twice, it can be said to be a coincidence, so many times, it can only mean that it is This serial killer avoided it. He didn't want to kill children."
Su Mian opened her mouth wide, bent down to pick up the mouse, and quickly flipped through the computer—really!
"So..." She raised her head and looked at Xu Nanbai, "This killer still has the last bit of kindness, only for children."
Xu Nanbai nodded.
Su Mian carefully mulled over what he just said, and she really learned a trick from him. She couldn't help but admire him. She simply smiled and bowed her hands to him: "Senior brother, I've been taught! I'm throwing myself to the ground."
Xu Nanbai laughed and joked with her: "You don't have to throw yourself on the ground, just go and add a glass of water for me."
Su Mian happily took the cup from his hand, and went to the water dispenser to pick up the water.

"The second killer used poison. He should have been Xin Jia's partner." Xu Nanbai took a sip and said in a hurry.
Su Mian leaned against the table with him and nodded. She had only roughly flipped through the case data of the second killer, and had not yet had time to draw a picture. Now just listen to Xu Nanbai.
Compared to her tirade, his conclusion was much succinct: "First of all, of all serial killers, he kills the fewest people, and all of them are targets, never indiscriminately killing innocents - from the archives, only he and t have done it. This. Except for a few days after April 20, he retaliated and killed some ordinary citizens. This shows that his self-discipline is very strong, and he may even be the same as T, and his moral values have not been completely eliminated. "
Su Mian nodded.
"Secondly, even though he killed less, he was the most distorted one." Xu Nanbai pointed at the photos on the computer, "Look, every corpse he handled was caused by taking poisons such as potassium cyanide. , when he was found, his face was very ruddy and healthy. Not only that, the police also found at the scene that ironing tools and dressing tables had been used - he ironed the clothes of each deceased before putting them on, and his hair was also combed. No mess. The last few corpses, he even painted men and women with makeup."
Su Mian followed his fingers and looked, that was indeed the case. The men and women who put on make-up will not go to the point of heavy make-up. On the contrary, the faces of the dead are more vivid and vivid, like actors in the spotlight. This caused a chill in her heart.
Then I heard Xu Nanbai continue: "In the whole process of committing the crime, he also showed a certain taste and preference in dressing up the corpse. So I believe that he was between 25 and 35 years old, with a stable occupation and social group. .
Strict self-control and distorted madness are reflected in the same person, so in his usual life, he should be very decent and serious, but also extremely depressed. "
—
The information on the third killer is the least and the most mysterious.
There are not too many fancy means, the murderer just poached the victim's heart. According to the forensic autopsy report, the victim's heart was gouged out alive. This made Su Mian feel very uncomfortable.
"The murderer's methods are very neat and professional, and he has obviously received special training." Xu Nanbai said, "Occupation is a doctor, soldier, policeman...or at least received a period of training and study."
Su Mian nodded and looked at the information on the computer: "Apart from the target people, he killed all young and beautiful women, and his preference was obvious. He took their hearts as souvenirs, which represented a kind of plunder. As for why he plundered women What it means to him is still unknown."
"And the heart..." Xu Nanbai replied, "either make a specimen for preservation, or... eat it."
Su Mian was silent. Throughout the history of crimes, sometimes the simpler the criminals' means of committing crimes, the more cruel and perverted they may indeed be. He did not leave any extraneous traces at the scene, only came for a heart. It is indeed possible to eat it.
Because the materials were limited back then, the two could only discuss a preliminary portrait result. Su Mian then said, "Senior brother, then I will first enter the results of the discussion just now into the computer. I will find something new later, so let's continue."
"Okay, I'll look at the information again." He went back to his seat and sat down.
Su Mian quickly entered all the results into the computer. She was a little tired after all. She leaned back in the chair, closed her eyes and opened them again, but her eyes caught a piece of text on the screen, and she was a little lost.
Back then, one of the criminal leaders said this before being shot dead by the police. Unlike the dead peripheral gangsters, according to the archives, the criminal was responsible for a series of local suffocation cases and was a real serial killer.
He said, in fact, my life is already over. Later, it started to really burn.
