There was a brief silence in the room.
"Cough..." Han Bin light cough: "Lin Yuejiao and the dead DNA comparison, when can come out?"
"At the time of identifying the corpse, we had collected Lin Yuejiao's DNA and sent it to the technical team for comparison. I estimate that it will be as soon as this afternoon and as late as tomorrow morning." Tian Li answered.
Although it has been basically determined that the deceased is Xue Mengjiao, it still needs to be identified.
This is the same as that of friends and girlfriends. Even if two people love each other, the country will not recognize them without marriage certificate.
Han Bin opened a bag, took out a stack of documents and threw them on the table: "these are the information about the snowman case. Let's study it."
"Want and snowman case and case investigation?" Tian Li surprised way.
"Yes, the genetic material in the body of the deceased is exactly the same as that in the body of the snowman victim."
"Zhao Ming, put these on the projector. We'll have a discussion while we watch them."
"Where are Du Qi and Xiao Peng?" Li huidao.
"They have a mission." Han Bin light said.
Before, when Du Qi reported to Han Bin, Han Bin arranged a new task for him.
There is a dash cam on the Audi. Han Bin asked Duqi to contact the technical team to get the driving track of the Audi, and then compare it with the surrounding monitoring to find out the location of the victim and maybe the trace of the suspect.
Then, the projector began to play information about the snowman case.
Gu Yuwen, a 30-year-old native of laiping City, is a tall and pretty man.
The exact time of death is not clear, but the time of snow is January 22, 2019.
The location of the case was in the suburb of laiping city. There was not much monitoring around and there were few people. In addition, the weather was cold. The snowman didn't melt until noon on the 24th. The dead body was found on the afternoon of the 24th.
The dead were hidden in the snowman, undressed, kneeling on the ground, his hands tied behind his back.
The scene of the snowman case is not the first. The snowman victim was killed in a white Hyundai car.
However, when we found the white Hyundai Car, it was more than half a month since we found the dead. The scene around the car was destroyed, and the private monitoring around the car was covered because of insufficient memory, making it more difficult to collect evidence.
These situations are almost the same as the homicide cases investigated by Han Bin and others.
The difference is that the face of the first victim in the snowman case was not damaged, so it was easy to identify the victim.
However, due to the late discovery of the dead body, the scene was severely damaged, and not many valuable clues were found.
After reading the information, Han Bin has a certain understanding of the first victim of the snowman case.
Of course, this understanding is only the most basic, far less impressive than the personal investigation.
Han Bin glanced at the crowd: "what do you think?"
Li Hui was the first to say: "the modus operandi of these two cases are very similar, but there are also some differences. After the first victim was killed, his face was not destroyed."
"I think it's normal. It shows that the murderer was inexperienced in the first time and experienced in the second time, which also brought difficulties to the police investigation." Tian Li analysis.
Zhao Ming turned off the projector and came over: "I don't understand why the murderer of the snowman case chose these two targets. What do the two victims have in common, which attracted the murderer."
Han Bin picked up two pieces of gum and threw them into his mouth. He was also thinking about it.
The age difference between the two dead persons is 11 years old, one is a young girl, the other is a mature and young Fu, which are totally two different types,
Li Hui said with his fingers: "the two suspects, one is Gu Yuwen, the other is Xue Mengjiao, whose name is not the same; their age and temperament are also much worse; one lives in Yuhua District, the other lives in laiping City, where they committed the crime Not at all. I don't think there's much in common except for the similar modus operandi. "
"The killers all choose to commit crimes in snowy days and hide the dead in snowmen. What's the special significance of this?" Tian Li asked.
Han Bin frowned and thought for a moment, but he couldn't answer these questions: "it's difficult to have a deep understanding of the snowman case just by the information in the file. We have to go to laiping city to investigate."
"Team leader, it's been a year since this case. Even if we go to laiping, I'm afraid it's hard to get any clues." Tian Li Road.
"Let's go to laiping City, mainly to meet the families of the victims, and learn about the first dead person in the snowman case from them. Now the snowman case is no longer a separate case, and there is a second dead person. Once some information and clues overlap, it is likely to become a breakthrough in the case. " Han Bin said.
Zhao Ming asked: "brother bin, do you think the murderer will continue to kill?"
Han Bin didn't answer, because they didn't have a clear understanding of the murderer, didn't know his motive, naturally didn't know his purpose of killing, and didn't know whether there was a next target.Next, the Three Li Hui began to check the monitoring near the Audi car to find the trace of the murderer.
Han Bin continued to study the snowman case.
Only by thoroughly understanding the two cases can we find the common ground.
At more than 6 p.m., Du Qi and sun Xiaopeng came back.
Sun Xiaopeng took off his scarf and rubbed his hands.
Ducky put his briefcase on the table: "it's freezing to death. It's colder than the snow of the previous two days."
Li Hui smiles: "as the old saying goes, melting snow is colder than snowing. It's not for nothing."
"Hard work, sit down and get warm." Han Bin said.
Ducky took a cup of hot water and held it in his hand: "chief, we checked the track of the white Audi."
"What do you find?"
"On January 17, at 10 a.m. the day before yesterday, the white Audi car left the times community (Lin Yuejiao's home). Xue Mengjiao was the driver at that time. Then the Audi car went to the blue whale Plaza and left the blue whale Plaza at 4 p.m. Xue Mengjiao was still the driver at this time. She arrived at Shimian community at 4:30." Dudgeon pauses and goes on:
"at 5 p.m., the white Audi left Shimian community. At this time, the driver changed into the one wearing a hoodie, sunglasses and a mask. He went to Yanxi road and Qinling street, where the location was relatively remote. He stopped for about six hours until he arrived at the crime scene at more than 12 p.m."
"That is to say, Xue Mengjiao had not been killed before 4:35 p.m. on January 17. He should have been killed near Yanxi road and Qinling street." Li Hui analyzes the situation.
"We went there and saw that the parking place was far away. It was a piece of wasteland nearby. There were basically no people at night and there was no monitoring around." Said duchy.
"Have you found anything?"
Duchy shook his head. "No."
"If you want me to say, the real murder scene is in the car. Even if the car is parked there, there is no need for the killer to get off the car." Li huidao.
"What does Xue Mengjiao do in Shimian community?" Zhao Ming asked.
"I don't know, but according to GPS, she often drives to Shimian community."
"I think it's necessary to go to Shimian community. The dead should be subdued there." Han Bin analysis.
"I agree with bingo. Shimian community, I know, is an old community. Although the living environment is average, the population is relatively dense. If there is a conflict between the two sides, it is likely to be seen by the residents there." Sun Xiaopeng agreed.
Li Hui began to read his notebook: "I remember taking notes with Lin Yuejiao before. She said that Xue Mengjiao had sent a wechat at more than 5 p.m. the day before yesterday. The original words were" I'll go to my father's house for a few days ". According to our conjecture, Xue Mengjiao should have been controlled by the murderer before 5 p.m., and that wechat was probably sent by the murderer."
"I'm going to stay with my dad for a few days." Tian Li murmured and analyzed: "to be able to say these words proves that the murderer has a certain understanding of the family situation of the deceased, and it is likely that the murderer was an acquaintance."
