"What are you doing! Is it over in the evening? "

Residential buildings on the edge of the alley.

A bleary eyed man pushed open the window and shouted, "square dance gangnima stops, what the hell is it?"

After being scolded by the man who was hurt by the noise from the square dancing aunt, he vented his inner experience and reached out to close the window.

Inadvertently looked down, and the hand closing the window was stunned.

He rubbed his eyes, looked at the man hanging on the iron door, and trembled to feel his mobile phone from his pocket.

"Hello, 110... We have a man hanging on the iron door... Yes, his body was pierced by the sharp thorn on the door... Yes, through."

……

11:30 p.m.

Tianxin police station.

Zhong Tianzheng and his party analyzed the clues they currently had on Wang Feifei's case.

At this time.

Suddenly someone came in outside the door.

"Team leader, there was a sudden homicide in the new area. One was killed and one was injured. The dead one was Xue Xiaodong. It was the person we were looking for. The injured one was missing."

Let's briefly report the key points.

"Get out of the scene!"

As soon as the group leader was excited, he got up from his seat and said, "ah Zheng, Ah Xiang, you follow."

"Yes!"

They answered and quickly followed out.

……

The group leader and his party arrived at the scene. After showing relevant certificates, they opened the cordon and entered the scene.

"Tian Xinfang group, right?"

The commander in charge of the scene glanced at the four people, his eyes fell on the oldest group leader and stretched out his hand.

The group leader also reached out and shook it as a greeting.

"At night, someone called the police and said someone was hanging on the iron door..."

The on-site commander came straight to the point and went straight to the theme: "when we came here, the situation on the scene was just like what you saw. The doctor said that the man was gone on the spot. When he crossed the iron door, he was directly pierced through his kidney by a sharp thorn, pierced his blood vessel, causing internal bleeding, and died through the whole."

"We have already asked the police officer, that is, the witness. More than ten minutes ago, he was sleeping at home and vaguely heard a voice in the alley, but he didn't pay much attention."

"But then the noise became louder and louder, and there was a faint sound of fighting. From time to time, someone was knocking on the iron door. Finally, the iron door shook a few times, and the sound suddenly disappeared."

The person in charge of on-site command quickly shared with them the clues they currently had: "at this time, the alarm man got up and opened the window to check, but the scene has been quiet. Now it looks like what he sees."

Reality is very different from film and television drama.

In TV dramas, there may be cases of competition between two groups, but generally speaking, this is not the case.

Whatever the case.

The first purpose of the police is to think of the case as quickly as possible, and to capture the suspect, so few people will hide what they are looking for.

"After our on-site investigation and the description of the police, we can preliminarily conclude that this is a homicide."

The commander quickly said his analysis: "the fighting sound at the scene will not be said. The identity information of the deceased shows that he lives nearby. Moreover, we found obvious signs of pushing and towering in the back of the deceased's head."

The commander took out his mobile phone and called out the picture: "his hair was smeared with a lot of hair gel, and both sides were very flat. Only this place had a disturbed hair style. Therefore, when the two sides were compared, it was obvious that someone attacked him from behind."

"Of course, no obvious trauma has been found on him at present."

"OK."

The group leader nodded: "my subordinate said that one died and one was injured, and the injured one ran away?"

"Yes."

The person in charge nodded, pointed to a pool of blood on one side of the ground and said, "there is no wound on the dead, but there is another pile of blood here. Moreover, pay attention to the ground."

The alley is an ordinary cement floor, which is covered with daily stains.

At this pile of blood stains, the surrounding stains have obvious friction marks.

"What about the surveillance nearby?" The group leader asked.

"No clue."

The person in charge shook his head: "this community is very old. The lights in the alley are very dim. As for monitoring, it doesn't cover here."

"Alas."

Speaking of this, the person in charge sighed: "earlier, the relevant departments had paid attention to this place and proposed to install monitoring, but unexpectedly, the nearby owners strongly opposed it, saying that there was no personal privacy."

"Guess what led the opposition?"

"He?"

The group leader looked at Xue Xiaodong on the iron gate.

"Ang."

The person in charge nodded and said nothing else.

After Zhong Tianzheng and Ah Xiang entered the scene, in addition to listening to their dialogue, they began to pay attention to the whole blockade.

On the iron door.

A simple scaffold has been built, and two firefighters holding liquid oxygen guns are dismantling the iron door to remove the dead from the iron door.

Zhong Tianzheng swept his eyes. Xue Xiaodong, with messy hair and drooping head, began to look around.

Blood on the ground.

Dirt on the ground.

Friction marks on the wall.

He caught every detail.

Zhong Tian is bending down and pinching a bar of soot from a dry ground on the ground.

The soot turns into powder.

Zhong Tianzheng spoke first before the professionals who were investigating the scene made an analysis.

"There are at least three or more people at the crime scene."

"So soon have a judgment?"

The person in charge glanced at the members of the survey team who were still searching at the scene and looked at Zhong Tianzheng in surprise: "what's your basis?"

"Basis? These are the traces at the scene. "

Zhong Tianzheng pretended to wave his hand easily: "the place where the murderer had contact with the dead for the first time should be here."

"Then, the other party raided from the rear and stretched out his hand to press the dead, that is, Xue Xiaodong's back neck. That's why there are messy marks behind his hairstyle."

"The two also met here, and then there was a conflict, but the killer didn't succeed. Xue Xiaodong escaped and ran in the direction of the iron gate. At this time, a third person appeared, and Xue Xiaodong finally died on the iron gate."

"If I'm not mistaken, Xue Xiaodong didn't have a bloody conflict with the person he first came into contact with."

Zhong Tianzheng said his inference.

In my mind.

The grandmaster's spatial imagination is divergent, a crime scene is formed, and the crime scene is perfectly restored.

The person in charge raised his eyebrow: "how did you judge it?"

The field survey personnel with rich experience have not made a judgment yet. How Zhong Tian judged it makes him a little hard to believe.
