Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 427 Verbal Stress Response
Around the conference table, members of the serious crime team sat in a row, with relatively relaxed expressions on their faces, and everyone was talking and laughing.

For the police to solve crimes, sometimes their thoughts are heaven and hell.

Just a second ago, everyone was wandering around like headless chickens, unable to find clues, unable to sort out the clues, and feeling that solving the case was far away.

But maybe a call will come in the next second telling you that the suspect has been caught.

The Wangjiahe corpse dumping case gave everyone such a feeling.

Although before conducting a large-scale investigation of the suspect, the crime team had already roughly identified the suspect based on the suspect's behavioral characteristics, the victim's background work characteristics, the time span of the murderer's crime, etc., and he is likely to live on Beifang Street, and One clue is that I once lived on Nanshan Road.

Even so, there are more than 3 permanent residents living in Beifang Street.

There are probably more than 4 floating people, which adds up to a population of [-] to [-] people that need to be investigated. This work cannot be completed in a day or two, it can take up to ten days and a half.

And everyone here actually knows that there is a high probability that this kind of large-scale investigation... will not have any particularly obvious results.

On the one hand, this is because such a large-scale investigation will definitely alert the suspect, so the suspect may be prepared and may not reveal any clues when responding to the investigation.

Another aspect is that the police officers themselves will unconsciously relax their vigilance after a large number of visits and investigations and no results.

In other words, judging from past case handling experience, if no substantial progress is made in the large-scale investigation and planning work at the beginning, then as time goes by, the possibility of progress will become smaller.

What no one expected was that less than half an hour after the investigation started, good news came.

"I heard that it was an old policeman from the Renmin Road Police Station who was about to retire, and he and an auxiliary policeman arrested him?"

When the members of the crime team arrived at the scene, only the suspects were left. Because Zhang Erhe was injured, Sun Jianguo took him to the hospital.

Therefore, the people from the serious crime team did not see Zhang Erhe and Sun Jianguo. Only Chen Jiang, the director of Renmin Road Police Station, was at the scene at that time.

"I have an acquaintance here in Tianzhou and I just asked about them. These two people are quite interesting. The old policeman's name is Sun Jianguo, and he will retire in more than a month. The auxiliary policeman is his neighbor's child, named Zhang Erhe."

Song Mingguang told everyone what he learned about the situation at that time.

"Both two of them knew the criminal suspect Song Tiejun. Zhang Erhe and Song Tiejun grew up together, and Sun Jianguo grew up watching Song Tiejun and Zhang Erhe."

"During the investigation, the two of them didn't find anything unusual at first, but while chatting, they suddenly remembered that Song Tiejun had lived in Nanshan Road for a while when he got married. After his father passed away eight years ago, he got divorced and returned to his hometown. street."

"After Sun Jianguo discovered that he had doubts, he did not rush to take action. Instead, he wanted to report it and then see if he would arrest the person. Unexpectedly, as soon as the two of them were about to go out, Song Tiejun became murderous, took a kitchen knife, and came from behind. Just chop two people."

"Zhang Erhe has practiced Sanda before, and his skills are relatively good. Although he was hit on the left shoulder, he did not lose his fighting ability immediately."

"Then this auxiliary police officer must have at least a second-class meritorious service this time. He will definitely be promoted to a full-time officer."

"I heard that this auxiliary police officer had already applied for a regular quota this year, but it has not yet been decided. Now with this case, it is certain that there will be no problem at all. In his case, he does not even need to occupy the quota."

Everyone is from the local municipal bureaus, and they are very clear about things like auxiliary police officers becoming regular officers.

In every aspect, Zhang Erhe's blow was worth it, but having said that, the blow was on Zhang Erhe's shoulder. If it had hit his neck and broken a major artery, there might have been another result.Just like the auxiliary police officer who jumped into the river to save someone in Tianzhou City last year, he jumped into the river without hesitation even though he was not good at water, he was not wearing a police uniform at the time, and he knew that he might drown if he jumped.

Sometimes, the choice between standing up like a hero or hiding like a coward is just a matter of seconds.

"Okay, let's talk about the case first."

Although the interrogation just now did not go well, as Song Mingguang said, the person was arrested, and the rest was just a grind.

Li Donglin sat in the first place, feeling relaxed.

"I think the suspect Song Tiejun's situation is likely to be a verbal stress reaction. Hearing the words 'Mama Pi' stimulated his desire to kill."

"I agree with Lao Wang's judgment that this kind of verbal stress reaction is not uncommon, but how did the other party form this kind of verbal stress reaction? I wonder if I can check it from his divorced ex-wife?"

Li Donglin nodded and just asked Wang Song to suspend the interrogation. In fact, that was what he meant. He wanted to investigate why the criminal suspect Song Tiejun had such a verbal stress reaction.

Generally speaking, language stress response is related to habit formation and is not formed overnight. Only when a person is strongly mentally oppressed or stimulated, a specific language may become a stress response condition.

Just like training a pet dog, it is impossible for a dog to understand people's words, but when its owner calls the dog's name, such as "Big Yellow", the pet dog will react and know that the owner is calling it. The reason is that the pet The dog had a stress reaction to the pronunciation of the two words "rhubarb".

Of course, the mechanism of human verbal stress response is more complicated than that of pets.

It cannot be achieved simply by repeating it or tempting it with dog food.

"I think it should be like this. Song Tiejun's ex-wife is originally from Sichuan Province, so she should speak Sichuan dialect. Since he is a married woman, he probably suffered a lot from his father-in-law's family."

"Mamapi is also a curse word in the Sichuan dialect. It may be that Song Tiejun did not live well in his ex-wife's family. For example, the family scolded him and bullied him. Over time, this kind of reaction formed."

"Old Song, it's up to you to investigate this matter and get the results as soon as possible."

"Yes!"

When the crime team was meeting in the conference room, Tianzhou No. 1 Civil Hospital.

"How is Erhe?"

Outside the operating room, Sun Jianguo chased the doctor who had just completed the operation yesterday.

"It's nothing serious. Although the incision was deep and hit the bone, it didn't hurt the vital parts. It just caused excessive blood loss. Pay attention to anti-inflammation later and it will be fine after a while."

"Will there be any sequelae?"

"Don't worry, it won't affect the function of your arm."

After hearing the doctor's affirmative answer, Sun Jianguo was relieved.
