At noon, investigators from all walks of life returned one after another, and Li Fangfang's group brought back an 'important clue'.

When Li released them, when Dong Haonan's son Jingjing's kindergarten learned about the situation, Jingjing's class teacher reported that just last week, because of Jingjing, Dong Haonan and his wife had a fierce conflict with the parents of another child in the class, and finally the dispute was stopped under the mediation of the police in the area.

"We found the parent who had a conflict with Dong Haonan, but he had alibi evidence, so we just took his fingerprints and DNA samples and sent them to the technology center. Li Fangfang said.

Xiao Ran knew that this clue was of little significance, so he just asked, "How is the size of the human body, and how tall is it?"

"Quite tall and strong, at least 1.8 meters. Li Fangfang recalled.

Xiao Ran shook his head, "You guys are walking too fast, and you haven't learned any follow-up clues." The murderer at the scene left footprints, and it is inferred that the suspect is about 175 tall, so the parents of this child can basically be ruled out. ”

"What the hell. ”

Qin Zihe next to him scolded in frustration, "The family surnamed Dong is too capable of causing trouble, our group has found dozens of suspects who have clashed with his family in the morning, this is still on the surface, and I don't know how many there are in secret." ”

"Screening one by one is too time-consuming. ”

Xiao Ran got up and took a pen and paper, "But don't worry, you haven't understood many clues at the scene yet." - Let's have a meeting first, and then maybe we'll be able to eliminate a lot of people at once. ”

"Do you know anything again?" Li Fangfang hurriedly followed Xiao Ran, looking curious.

Xiao Ran shook his head slightly, and said uncertainly: "I have some ideas, but I am not sure, and I will continue to verify it next." ”

At 1:40 p.m., the '614 Door Destroying Case' task force began its first case discussion meeting to analyze and study the direction of the next investigation.

Walking into the conference room, most of the people in it were already seated, Zhang Lei sat in the corner and beckoned to Xiao Ran, Xiao Ran sneered, he was worthy of being a roommate who had slept in the bunk for four years, and he had helped him occupy his old position in advance.

But then again, no one wants to rush to sit in that corner seat.

Sitting down next to Zhang Lei, Xiao Ran looked up at the whiteboard on the side of Deputy Bureau Lei's hand, with a photo of the deceased's family in the middle, and several close-ups of the traces of the scene next to it.

But the most striking thing is the dense arrows that spread out around the photos of Dong Haonan's family, each arrow corresponds to a suspect, but because there are too many arrows, those photos are almost impossible to paste on the whiteboard.

Zhang Lei was next to Xiao Ran and whispered: "So I keep saying, you can't be too many, it's just a good person to provoke, it's really ruthless, that's the end, the family is neat." ”

Xiao Ran shook his head slightly, spread out his notebook, and briefly sorted out his thoughts, as for discussing the deceased's good or bad life,—— he is not a teacher, his obligation is only to bring the murderer to justice.

After the personnel arrived, the internal staff first reported the relevant situation, and Forensic Doctor Xue then introduced the autopsy results.

As Xiao Ran expected, the deceased Dong Haonan was cut off by a thinner blade and a sharp weapon in his neck, Niu Bixiang was hacked to death by an axe, and the boy Jingjing was struck on the head by an axe, resulting in a skull fracture, not from mechanical asphyxiation.

"The time of death of Dong Haonan's family was determined to be last night, that is, around 10 o'clock on June 13. ”

Xue Qingxia said: "The deceased Niu Bixiang has lacerations on her lower body, but her life reaction is not obvious, and it is suspected that she was violated before she was killed, but in Niu Bixiang's body, no genetic material of the man was extracted. ”

The technician followed: "After investigation and analysis at the scene, it was basically determined that the footprints behind the body of the deceased Dong Haonan were left by the suspect. The traces on the pool of blood, as well as the footprints in the courtyard, were caused by Wang Bai and Wu Menghao after they broke into the scene of the crime during the theft. ”

"Judging by the length of the footprints, the suspect is about 1.75 meters tall, with a medium to thin stature, and on the axe left next to the body of the deceased Niu Bixiang, we have extracted several mutilated fingerprints, one of which has a comparison value. ”

Lu Qin said: "After urgent comparison, we determined that this fingerprint did not belong to Dong Haonan and his wife, and it is basically certain that this fingerprint was left by the murderer." However, on the parcel bag on the second floor of the deceased's family, which has not yet been issued, we also extracted a large number of fingerprints.

Although these fingerprints have not been completely classified and sorted out, it has been basically determined that most of these fingerprints belong to the same person.

And we also found that the fingerprint on the murder weapon is exactly the same as one of the fingerprints on the package, I don't know whether the murderer helped Dong Haonan's family pack the package before committing the murder, or rummaged through the package after committing the crime. ”

"Wait a minute. You said that the murderer may have rummaged through the package?—— the murderer is likely to have cleaned the computer before and after committing the crime, so have the traces of the computer's use been sorted out?"

Shao Yong frowned, interrupted, and said: "Could it be that the murderer's important things were inadvertently sold in a package by Dong Haonan's son?" After the murderer rummaged for no avail, he clashed with Dong Haonan's family, killed people in anger, and because it was a child, he also hung the child's body to vent his anger?"

"The situation of the computer, the brothers of the network detective are still working on it, and there are no clues for the time being. ”

Cai Wang took over and said: "However, in the process of cleaning up the relics of Dong Haonan's family, we found that the deceased's family's cash, bank cards, valuable jewelry and other items were all lost, and we suspect that the murderer committed the crime with financial factors." ”

"In addition, in the process of combining road surveillance and tracking the Haval car of the deceased Dong Haonan, we intercepted the scene of the murderer driving by at an intersection of Zhongshan South Road. ”

Cai Wang released a few photos on the projection screen, and the time of surveillance capture was around 11:26 p.m. on the 13th, in the picture, the Haval off-road vehicle with the license plate of 'Zhejiang A·J0827' owned by the deceased Dong Haonan was crossing the intersection from south to north.

In the driver's seat of the car, a short-haired man wearing a black mask and gray short sleeves can be seen, his face is slightly tilted to the right, as if he is observing the situation at the intersection.

As soon as Xiao Ran's gaze touched the man in gray, the eyes of justice jumped violently.

In fact, at this time, there is no need for the Eye of Justice warning, after the crime, the deceased's car was driving near the scene, and normal people know that this person is a major suspect!

Xiao Ran looked at the image on the curtain carefully, as if he wanted to imprint every detail in his heart, and suddenly, he keenly noticed that although this man's face was turned to the side, his eyes were always looking straight ahead!

"This man...... He's got a problem with his eyes, his eyes are slanted!"
