Then why did he only pick out one of Zhu Lingling's eyes? What is this operation? Yue Yang asked.

"Demonstrations, provocations, he is challenging the bottom line of the police." Tang Tao took a deep breath and said: "This murderer did it on purpose, he had the time and ability to pick out Zhu Lingling's eyes, but he didn't do it, he wanted to leave an eye for Zhu Lingling, first, to let her go to the police station to report the case, which is also the real reason why the murderer threw her near the police station, and secondly, to let her see her miserable life in the future, to let her live better than dead, the reason why Zhu Lingling's eyes were gouged out with his hands was because the movements of his hands were slower and the crime took longer, In this way, the victim's senses will be clearer, the fear will gradually deepen, this memory will go deep into the bone marrow, can never be erased, the murderer is deliberately posted the video on the Internet, the purpose is to cause panic among the masses, further to the police pressure, he also deliberately played the clown, is to deliberately imitate the murderous clown, deepen everyone's fear, as far as the information in front of him shows that the murderer must have suffered a great blow, with a serious psychological shadow, he not only committed the crime but also to make it public, He wants everyone to see that he has a deep hatred for the police in society, he hates everyone, this person must have experienced something related to the police, and even said that he has been dealt with by the police, he hates all good things, and his heart only destroys and kills. ”

A bloody picture came to everyone's minds, in a dim environment, a clown held a knife and slowly cut Zhu Lingling's face, cut her nose and tongue, and finally slowly pulled out Zhu Lingling's eyes in Zhu Lingling's screams.

That's when Zhang Zhang spoke.

"Can you close all the curtains around and put the video again?"

"Yes."

Jiang Fan nodded to his colleagues, and several policemen immediately got up and closed all the curtains.

"Turn off the lights, turn on the loudest sounds, and don't speak."

The lights went out, the conference room suddenly darkened, and the big screen emitted a cold white light, as if in a movie theater, the video replayed, and the sound was turned on to the maximum.

Zhang Zhang closed his eyes and listened carefully, many people present did not know that in addition to being a doctor of biology and materials, Zhang Li is also a well-known firearms expert in the country, a bullet mark expert, and his hearing has become extremely acute when he has been in contact with firearms for a long time.

"I heard the whistle, it should be a train, and it was a truck, this car passed through a crossing, I heard three sirens, the place of the crime should be on the side of the railway, the distance is no more than 100 meters, and there is a crossing nearby, there is a warning light at the crossing, judging from the video, this house should not be inhabited for a long time." Tension made the judgement.

Jiang Fan squeezed his hands and said with some embarrassment: "There is a special track for the army in our old city, and the old city is being renovated recently, so many old houses are uninhabited, and there are dozens of crossings along the line. ”

Li Xiao, who was sitting next to Professor Lei, turned the computer around and said: "There are indeed dozens of crossings along the line, but there are only twelve warning lights, this is a list of the cost of the South China Railway warning lights I found from the Internet, each light has been registered, marked with the corresponding location, and now the range has been narrowed down to twelve points, as long as we investigate one by one, there will be results." ”

Li Xiao was in a hurry to express himself, completely unaware that he had stolen Jiang Fan's limelight.

Seeing this, Yue Yang hurriedly joked and said, "Li Xiao, this is your mistake, Captain Jiang hasn't finished talking yet." ”

Jiang Fan laughed heartily and waved his hand again and again and said: "Yue Yang, don't excuse me, it's our business that is not good at it, don't blame Li Xiao, he is right, now the scope has been greatly reduced, so that our next investigation has a direction, your serious crime team is really a hidden dragon and a crouching tiger, today is an eye-opener, I don't know what do you think of this murderer?" ”

Everyone once again focused their attention on Tang Tao's body.

Tang Tao pointed to the picture and said: "The murderer has been facing away from the camera, no matter how Zhu Lingling shouts, he is unmoved, from this point of view, this person has an extremely strong psychological quality, and he also has a considerable ability to counter-reconnaissance, the location of the crime and the place where the victim was abandoned have been carefully selected, combined with these characteristics, the murderer should be a man, between 1.65 and 1.7 meters tall, thin, aged about forty years old, he has been married, maybe divorced, has a decent job, and his appearance is handsome and handsome, Svenwen, he may be a senior employee of the company, he is introverted and rarely speaks, he is a very serious person, his financial situation is good, his income belongs to the middle and high-level, he has a higher education, this person has been in and out of the old city for a long time, he is very familiar with the terrain of the old city, he or his family has suffered serious injuries in ten years, and the police have not given him a satisfactory result, this is just the beginning, it will not be long before there will be another victim, and the action will escalate, the damage will be further aggravated, Maybe he's watching the news somewhere right now. ”

"Doctor Tang, you are really good, you have obtained the psychological portrait of the suspect so quickly, but how do you determine his age and income?" Mei Yingxue looked at Tang Tao with a little arrogance in her eyes, she is Jiang Fan's assistant, and she also plays with computers like Li Xiao, the difference is that she is more inclined to data analysis, many cases are based on well-documented data, and Tang Tao's psychological portrait is more like a guess out of thin air.

"Video, three minutes and five seconds when the suspect raised his hand, there was a strangulation mark on the ring finger of his right hand left by wearing a ring for a long time, which means that he was married and had worn a ring for a long time, he took off the ring may have been for the convenience of committing the crime, but it is more likely that he has been divorced, although his fingers are thick but very fair, such a hand looks middle-aged, and he must not be engaged in heavy physical work, at the last second of the video, his foot was raised to expose the soles of his shoes and the corner of his suit pants, It is a pair of black playboy British style business leather shoes, generally only older people like to wear this kind of leather shoes, suit pants, leather shoes, white fingers, and an elderly middle-aged uncle, plus this dress can be inferred that he must have a decent job, even said to be a manager, he should have a car, often in and out of the old city, the grade of this car should be hundreds of thousands of scooters, forty years old is a man's most mature age, old and young, If he hadn't been forced to do so, how could he have made such a crazy move, and if he had checked whether there had been any hugely controversial cases in the past ten years, maybe he would have been able to find some clues outside. ”

Li Xiao quickly pushed the screenshots of the two time points that Tang Tao said on the big screen, and enlarged and analyzed, the picture was almost all flashing and fleeting, but it was caught by Tang Tao in just a moment, and a comprehensive analysis was carried out, and the silhouette of a victim appeared in front of everyone's eyes.

"Okay, great, your serious crime team has been a great help this time, with these clues, I believe that the case will be solved just around the corner, Professor Lei, what do you think we should do next?" Jiang Fan's tense expression finally eased, and he clenched his fists with excitement on his face.

"In that case, I'll go to the scene, Yue Yang Zhang Li you go to the hospital, Tang Tao, you and Sophie go to the No. 2 Middle School to find Qin Na, Li Xiao stays in the criminal police team to investigate Zhu Lingling's social situation, Captain Jiang has to trouble your brother to cooperate with us, I also need you to provide a picture of the location near the crime location, the more detailed the better." Professor Ray said.

"That's what we're supposed to do."

"Alright, that's it, let's go our separate ways."
