After the examination on the first floor, the forensic doctor Jiang Xiran and the forensic assistant got up and went to the second floor.

The bloody footprints on the second floor are noticeably more messy, and it can be intuitively seen that they are two strings of one-way footprints back and forth.

Ling Zizhen followed behind Lu Ke, and said the results of the investigation of the bloody footprints as he walked: "After we compared, the bloody footprints on the second floor are exactly the same as those downstairs, the texture of the soles of the shoes is also the same, and the footprints have no traces of covering, indicating that there is only one murderer." ”

"One man killed four people?" Su Simeng gasped, walked and walked, suddenly thought of something, turned around and asked, "Could it be that the gang committed the crime, but they are of similar stature and wearing the same shoes?" ”

Ling Zizhen shook his head and directly denied: "This situation should be impossible, footprints are very critical traces, difficult to fake, everyone's step spacing, step frequency, walking posture, and the degree of wear and tear of the soles are all different." And the bloody footprints of the entire villa are one-way, and if it is a gang crime, there will definitely be covered footprints. ”

Lu Ke nodded and walked towards the bedroom where the crime occurred.

A middle-aged woman was lying on the ground next to the bed, there were blood splatters everywhere on the wall, bed, and bedside table, and there were still no traces of a fight in the room, and there was not even resistance, and the process of killing only happened in an instant.

Jiang Xiran walked to the side of the corpse, glanced at the deceased's head, and said lightly: "It's exactly the same modus operandi." ”

Zhou Xiaoyi squatted down and reached out to touch the deceased's skull: "Section Chief Jiang, the third deceased also suffered a skull fracture and died of severe head injury. ”

This was already expected by Jiang Xiran, she just nodded lightly, counted as an answer, and then looked at the bloody footprints on the ground, feeling inexplicably tight in her heart.

Because this series of bloody footprints came up the stairs, went directly to the bedroom, and after a short stay with the third deceased, he walked directly towards the little boy on the bed.

Seeing the bloody footprints stretching all the way towards the little boy, Jiang Xiran even had the picture of the time of the crime in his mind.

A hideous-looking, bloodied devil, holding a blunt object in his hand, walked towards the little boy with a blank face, and then brutally killed him......

Jiang Xiran took a deep breath and shook his head slightly, letting this image disappear from his mind.

Walking towards the little boy, Jiang Xiran saw an identical wound, because the little boy's was not fully developed, and his skull was small. The same wound was visible on his head, and even brain tissue could be seen in a fist-sized hole.

She froze and said lightly: "The wound of the fourth deceased is also in the head, and the violent blunt blow caused a serious skull collapse,"

Lu Ke stood at the door of the bedroom, carefully looking at the layout and structure of the second floor, and thought of the route from the stairs to the second floor directly after the murderer killed on the first floor, indicating that the murderer knew the layout of this villa very well, and after coming to the second floor, he went directly into this bedroom without a moment of hesitation.

This is an acquaintance who committed a crime, and the murderer and Wu Changhai's villa structure must be very familiar.

In such a familiar situation, what is the deep hatred that can cause such a murderous murder case? Not even a single child was spared......

Su Simeng, who was beside him, seemed to have penetrated Lu Ke's thinking, and suddenly said: "People nowadays have a great hatred for the rich, plus Wu Changhai is the richest man in Jing'an, and he looks down on the poor, so it is very likely that he will suffer revenge." Or maybe there is a rival company in business and some kind of grudge? ”

Lu Ke twisted his fingers: "Let's first investigate the social relationship of Wu Changhai's family." ”

Ling Zizhen then spoke: "After the murderer killed four people in a row, he began to rummage for things, focusing on this bedroom and the living room downstairs, because it is not clear the number of items of the deceased's family, and it is not known what the murderer took away for the time being, but after preliminary investigation, the gold and silver jewelry on the deceased was not lost, and the gold watch on the wrist of the first deceased was not stolen. ”

Lu Ke frowned suddenly, as if he was very puzzled by the murderer's behavior.

There are too few clues at the moment, so don't think about things that you can't figure out, and you should still focus on the scene of the crime.

"Let's call up the surveillance nearby." Lu Ke said lightly.

Ling Zizhen shook his head: "This is a lot under development, and the follow-up of various facilities is not perfect, and the monitoring probes are mainly concentrated at the intersection, and someone has been sent to retrieve it, but there should be no clues." ”

Several people walked down the stairs and returned to the living room on the first floor.

After a while, Mo Yufei ran back quickly and brought back the identity information of the four deceased.

This is a burglary and homicide case, and it has been determined that this is the home of Wu Changhai, the richest man in Jing'an, with the cooperation of the police in the jurisdiction, it is easy to obtain the identity information of Wu Changhai's family, and after comparison, it is easy to determine the identity one by one.

No. 1 deceased: Wu Changhai, male, 59 years old, owner of the villa, the richest man in Jing'an, a well-known entrepreneur.

No. 2 deceased: Wu Xiaoxi, female, 28 years old, Wu Changhai's eldest daughter.

Deceased No. 3: Dai Lihong, female, 54 years old, wife of Wu Changhai.

Deceased No. 4: Bian Yitong, male, three years old, son of Wu Xiaoxi, grandson of Wu Changhai and Dai Lihong.

The identities of the four deceased were determined, which laid a key foundation for the next investigation of the case, and at the same time, it also gave everyone a more direct understanding of the murder case.

Whether it is the murder of Wu Changhai, the richest man in Jing'an, or the death of a three-year-old boy, it has attracted widespread attention from all walks of life.

The Provincial Public Security Department ordered the Jing'an City Public Security Bureau to immediately set up a special case group to immediately start the investigation and handling of this case, and all departments should give full assistance to give the green light to the investigation of the case.

A few hours later, the criminal police team of the Jing'an City Public Security Bureau convened an urgent case analysis meeting.

Lu Ke looked serious and said seriously: "The nature of this case is extremely bad, and the social impact is extremely serious, the provincial department has ordered the establishment of a special case team, although there is no time limit to solve the case, but we must hurry up." This time we are under a lot of pressure, everyone cheers up, is ready to work overtime and stay up late, is not allowed to ask for leave unless necessary, and requires all the criminal police who are on vacation to be on duty. ”

Whether it was from Lu Ke's words or the tense atmosphere in the conference room, everyone felt pressured.

Lu Ke took a deep breath and said in a deep voice: "Everyone has understood the situation at the scene of the crime, and the identity information of the four deceased has also been announced, let's talk about their respective investigations." ”

At this moment, the forensic department, trace examination department, laboratory department, technical investigation department, household registration department and other departments of the Jing'an Municipal Public Security Bureau are working synchronously, the time is pressing, and everyone does not have many clues, but through the internal system network of the Public Security Bureau, some relevant information about the case has been found.

At present, it is imperative to determine the direction of the investigation of the case, especially around the social relations of the deceased.

Burglary murder, murder case, the murderer and the deceased's family must have some kind of blood feud......
