Chapter 58 Chapter 58 Please don’t call me a policewoman. …
Although Gong Lingling had an alibi and was temporarily excluded from the suspect range, their trip was not without gain.
It turns out that the third victim in the serial dismemberment case found in Tongrong River was named Lin Qingliang!
This was a major breakthrough. After Tan Li got in the car, she glanced at Ji Yinhe calmly and praised him verbally: "Well done, keep it up."
Comrade Xiao Ji was stunned for a moment, then smiled brightly and answered loudly, "Okay! Thank you, Captain Tan!"
After returning to the provincial department, Tan Li immediately asked Sun Gaoge to issue a joint investigation notice to all municipal bureaus in the province, asking local branches and police stations to cooperate in finding Lin Qingliang's household registration information.
——It’s a pity that a day passed and nothing was gained.
The current system and awareness are not perfect, and with the increasingly strict family planning policy, many unregistered residents have appeared in towns and villages due to various reasons.
Tan Li speculated that Lin Qingliang might belong to this group.
This brought the progress in the case that had been made with great difficulty back to square one.
In the evening, Ji Yinhe finished organizing the materials, squatted in front of the window with his cheek in his hand and ate corn.
The provincial department can certainly handle major cases, but the process is much more complicated than in Jiangtan, and there is a lot of paperwork to fill out.
According to Jiang Nian, who is in charge of technology, everyone will have to be equipped with a computer in the future, and a lot of work will have to flow through it.
This made it difficult for the newly arrived police officer Xiao Ji to adapt.
She threw the finished corn cob into the trash can and secretly squeezed her palms.
——After finishing this big case, I must seize the time to practice driving and computer skills well!
The office was quiet at the moment. Tan Li, Guan Ye, Sun Gaoge and Zhao Zhuoqun were still outside, investigating and visiting the younger brothers and sisters that Lin Qingliang had contact with in the hair salon. It seemed that they would not be back for a while.
Ji Yinhe was wondering whether he should go to the technical institute downstairs to say hello to the forensic doctor Lu Xiaoyan's team assigned to the crackdown team, when he heard a whirring sound of rollers.
When I stood up, I saw Lu Zheng walking in from the corridor, pushing a large blackboard.
Ji Yinhe blinked and looked at him.
"Don't you like to use blackboards to draw... mind maps in Jiangtan?" Lu Zheng tilted his head and smiled. "The office just replaced a batch of them, and I asked for one."
Ji Yinhe opened his mouth slightly: "Ah..."
Tan Li also has the habit of organizing her thoughts, but she writes them down on paper and then mimeographs them to distribute to everyone.
Comrade Xiao Ji thought, she is just a new police officer, so making such a big fuss is not appropriate...
But Lu Zheng seemed to see through her thoughts and smiled and said, "I've measured the size. This blackboard will fit perfectly on the empty space behind your desk against the wall. It won't attract attention normally... and it's a discarded old item. Even if Team Leader Tan found it, he wouldn't say anything."
Ji Yinhe breathed a sigh of relief, trotted over, grabbed the edge of the blackboard and pushed it inwards, "That's great, thank you Teacher Lu!"
If it were someone else, they would probably say, "Why are you being so polite to me?", but Lu Zheng just looked at her quietly, with a slight glint in his black and white eyes.
Ji Yinhe was a little embarrassed, "...w-what happened?"
"There's a little corn kernel on the corner of your lip." He considerately took out a pack of expensive and hard-to-buy handkerchiefs.
Ji Yinhe hurriedly pulled out a piece of paper and wiped the corner of his lips carelessly.
Lu Zheng didn't look at her again, but lowered his head, took out a document from his bag and handed it to her.
"This is the fingerprint found on the cosmetics in the salon locker, and this is the fingerprint on the victim's body." He tapped on the paper. "The results match."
"Great!" Ji Yinhe's eyes sparkled, "The deceased is indeed Lin Qingliang! I'll tell Captain Tan when she comes back!"
Lu Zheng leaned against the desk, his long legs swinging leisurely.
"What are your thoughts on this case?" He asked her seriously, "Any opinion is fine."
Ji Yinhe tilted his head and thought for a moment.
Then he took out a piece of chalk and started writing on the clean blackboard.
"Serial Dismemberment Case." She looked at the five large characters and whispered, "It's actually a type of serial murder, only more bloody and brutal."
Lu Zheng hummed lightly.
Ji Yinhe wrote a small title below, "According to the theoretical book you gave me, serial killings—that is, killing three or more people at three or more locations and times."
“This case fits the bill.”
Ji Yinhe continued to mutter, "Secondly, most ordinary murders are motivated by hatred, power, wealth, love, and sex. However, this is not necessarily the case with serial killers. The killer's purpose is often to kill, and the victims are usually not acquaintances of the killer."
Lu Zheng chuckled. "So you also feel that Tan Li's standard visit to Lin Qingliang's circle is actually a futile effort, right?"
Ji Yinhe made a shushing gesture and said, "I dare not say anything nonsense."
She turned her head and crossed her arms, tapping her elbows with her long fingers.
"Also... I read in the FBI Behavioral Analysis Unit's files that serial killers usually have a psychological cooling-off period."
Chalk quickly wrote the third point on the blackboard. Lu Zheng said thoughtfully, "Well, if the murderer's cooling-off period is over, he will soon continue to kill in order to satisfy his own pleasure!"
"Yes..." Ji Yinhe sighed softly, "So time is of the essence. We must find the murderer as soon as possible."
Lu Zheng continued, "I think the key lies in what this serial killer is thinking...what motivated him to choose these men as his targets."
“Hmm…”
The office fell silent, and Ji Yinhe's lips were tightly drawn.
Theoretical textbooks do not provide the most practical answers, but the other party is too cunning, and the clues they have now are too few to make even the most basic profile.
…If only I could talk to a similar murderer.
However, unexpectedly, Lu Zheng spoke at this moment.
"I heard that when you were handling the national treasure theft case last time, you interviewed the thief Guo Jianglong whom we caught at Jiangtan Railway Station?"
Ji Yinhe was a little embarrassed. "Yes, it was just an accident. He provided a lot of valuable clues."
This is an unconventional approach, and few police officers would learn from prisoners, but Lu Zheng took a step towards her and nodded sincerely.
"In fact, when I was interning at the FBI, the experts there would also improve their criminal psychology system by talking to the murderers."
"Really?" Ji Yinhe was a little surprised. This was completely a coincidence!
"Of course it's true." Lu Zheng took another step forward, a faint soapy scent wafting over him. "After all, they did the same ruthless thing, so they should have the same ruthless mentality... People like them understand their own kind best."
Ji Yinhe repeated this sentence silently, and it took a while for him to realize that when Teacher Lu said this rather cruel sentence, he actually used a gentle tone.
She sniffed, took a deep breath, and asked loudly, "Has Jingzhou ever caught a serial killer before?"
Lu Zheng laughed, "Of course, and I also participated in the arrest operation. He is now imprisoned in Handong Provincial Prison."
Ji Yinhe's eyes lit up and he jumped on the spot.
"Let's go! Let's go talk to him!"
*
The Grand Cherokee drove through the open iron gates. The provincial prison was very old and also served as a diesel engine factory. Its yellow-gray walls were covered with tall, impenetrable iron mesh, making it look much more eerie and terrifying than the Jiangtan City Detention Center.
On the way here, Ji Yinhe listened to Lu Zheng briefly talk about the evil deeds committed by the serial killer named Situ Feng.
He was not as brutal as the murderer in this case who killed and dismembered people. Instead, to satisfy his stamp collecting psychology, he killed three homeless women and buried their bodies in his own vegetable garden.
But this was perverted enough. Ji Yinhe turned to the last news clipping.
It said that Situ Feng's case has reached the stage of death penalty review, and if nothing unexpected happens, he will be executed by firing squad next month.
"I'll go in with you later." Lu Zheng stopped the car and pulled the handbrake.
"I can do it alone!" Comrade Xiao Ji straightened his back, glanced at him, and thought for a moment, "That's fine, you're more familiar with him."
Lu Zheng couldn't help but smile.
Unexpectedly, after entering prison, Situ Feng refused to meet with Lu Zheng because he was "more familiar" with him.
"I don't want to see the expert who brought me here!" An angry roar came from the meeting room.
The prison guard was no pushover and scolded, "The police are questioning you, and you still have the right to be picky!"
Situ Feng rolled his eyes, looking like a dead pig that was not afraid of boiling water. "Whatever you want, then I won't say anything! I'm going to die anyway!"
The door was suddenly pushed open and Ji Yinhe walked in alone.
"Can I talk to you?" she asked with a smile.
When Situ Feng saw that she was a strange pretty little girl, he immediately became very happy. "Okay, okay, you should have said it earlier. I have always been very friendly to little police girls."
"Please don't call me policewoman." Ji Yinhe curled the corners of her lips politely. "My name is Ji Yinhe. Please call me Officer Ji, or Comrade Ji."
"Okay, okay..."
Lu Zheng, who was standing outside the meeting room, heard the roaring from inside stop and breathed a sigh of relief.
However, he was still worried that the serial killer would break free from his shackles and do something to hurt Ji Yinhe, so he handed the prison guard two packs of good cigarettes that he had in his pocket as a backup and said, "I'll wait here, okay?"
The prison guard smiled knowingly and walked to the other end of the corridor.
Across the wall, Situ Feng said slickly, "So you are that Ji Yinhe..."
Ji Yinhe tilted his head, "Why, do you know me?"
"...Tong An, do you still remember him?" Situ Feng twisted the handcuffs on his wrists. "The criminal you captured with your own hands, a human trafficker! He's just been transferred from Jiangtan to the provincial prison, waiting to be shot with me next month!"
Ji Yinhe didn't expect to hear this name again, and nodded, "I remember, it was the prisoner I arrested half a year ago."
"Hey, you're pretty amazing!" Situ Feng became interested. "I admire you a lot, especially those who sell children. They're so morally corrupt! It's outrageous! I can't stand it!"
“…”
Ji Yinhe rolled his eyes in his heart, thinking that what you did was not much more righteous than others...
"Let's not get off topic. I came to you today because I have something to ask you." She raised her head and met his gaze with a cold stare. "Why do you serial killers keep killing people one after another? Do each victim hurt you? ... Or do you commit these crimes out of passion?"
Situ Feng looked at her and laughed, "Oh, the police officer also came to ask me questions! I heard from the prison guard, is it the dismemberment case?"
"yes."
Situ Feng lifted his hair and said, "What's the benefit? Can I avoid being shot?"
Ji Yinhe folded his fingers, "Please cooperate and answer. If it is useful... I will sincerely thank you for the information you provided."
"Well, you're really ruthless..." Situ Feng stared at her for a long while and shook his head. "Forget it, a prisoner as charming and charming as me should leave some benefits for Jingzhou..."
He hooked his finger at her and said, "Come here, I'll tell you in a low voice."
Ji Yinhe sat in his seat motionless.
Situ Feng met her eyes, "..."
*
Twenty minutes later, Ji Yinhe walked out of the meeting room quickly.
She showed the notes in her hand to Lu Zheng, but Lu Zheng frowned and asked, "You didn't get close to him, did you?"
"No, he stared at me for five minutes before finally giving in and answering the questions honestly." Ji Yinhe shook his notebook. "Look, based on what he said, I divided serial killers into two categories - organized, planned before committing the crime, which may be a personality disorder, and unplanned, sporadic, which is schizophrenia."
Lu Zheng stared at his notes, listened to her attentively, and said "hmm".
"If people with personality disorders don't receive timely treatment, their attacks will become more and more frequent..." Ji Yinhe anxiously grabbed his arm, "Teacher Lu, from the first bag of body parts to the third bag, the intervals between their appearances are getting shorter and shorter, which means the murderer's cool-down period is also getting shorter... If we time it, his next move might be in the next two days!"
