"According to the description of the mysterious expert, I think that the murderer is not only impulsive-aggressive personality disorder, but most likely, he also has repressive personality characteristics!"

Tang Xiaonian whispered, "Repressive psychology is a common social pathological psychological phenomenon, which exists in all ages, and is related to the environment in which it grows up, its family, and its own physiological character, mainly manifested in low self-esteem, depression, closure, and social avoidance, which can be light or severe. The murderer completed the third corpse shredding case, and built the wall himself, which shows that to a certain extent, he should be calmer, fearless, and more comfortable in dealing with it than ordinary people!

And in the face of the fourth victim, that is, the old woman, after discovering his abnormal behavior, he did not show his calm trait at all, on the contrary, the behavior of dealing with it was very flustered and irritable! ”

Tang Xiaonian paused, "Even when I knocked on the door for the third time, I couldn't bear it, I chose to open the door, and directly dealt with it by the most violent means, from beginning to end, I didn't open the door to disguise or explain, which shows that the murderer habitually has a evasive mentality, is not good at socializing, and even dodges, looking at it this way, there are certain repressive personality characteristics!" ”

The three of them nodded when they heard this, and Lao Bai answered, "If you suppress sexual personality characteristics, the reason is that there is motivation, instinct, and tolerance!" ”

"When the pressure, anxiety, and intolerability he is undergoing will explode, he will stimulate impulsive aggression disordered behavior, unable to control himself, and do things that are beyond his or even ordinary people's moral limits!" Tang Xiaonian continued, "For example, killing, blood, and dismembering corpses can be alleviated, so that he can be calm, and psychologically satisfied!" ”

"So......" Jiang Jingchen thought of something, "people who have these two personality traits and are serious to a certain level!" The deeper the level of pressure tolerance he is under, the longer the accumulated time, the more radical and excessive the outburst of behavior! ”

"That's right, like shredding corpses." Tang Xiaonian shook his head, "Turning a person, from whole, to cutting, and finally into pieces, even for a person like the murderer, who has too much psychology, it is also a high-level explosive behavior!" So ......"

She paused slightly, "From the combination of these two conditions, we can guess and judge that at least recently, the murderer did not get a certain degree of release in the process of accumulating pressure, and there was no act of release, so it led to the outbreak when he committed the crime eight years ago, and he did such a cruel act in one step!" ”

"In other words, in the near future, for a year or two, maybe the murderer has not committed a crime, let alone a file, so we don't need to investigate!" Jiang Tianhe summed up and asked.

Tang Xiaonian thought about it, shook his head and said, "I think we can set the time to five years." ”

The three of them raised their eyes.

"Looking at the murderer's treatment of the fourth deceased and the old woman, the shredding of the corpse is not the murderer's habit and addiction, for him, it may also be an explosive, rare and cherished highly released behavior, otherwise, for the sake of psychological satisfaction, he will definitely repeat the act of breaking the corpse again, and his behavior towards the fourth deceased old woman is based on 'being discovered' and' Hidden's motive, illustrating the murderer's psychology, in a case of dismembering the corpse, you can get a large-scale release satisfaction, and do not want to continue, if this frequency, and then according to the murderer's age and maturity to judge, I think, five years is more appropriate! ”

Tang Xiaonian analyzed, using the knowledge he had learned, very seriously, and raised his head, "Of course, we must also combine the case of Lingxin Hospital to conduct a random review of the five-year file before the case!" ”
