After returning to the unit, Bai Song found that he was not as sad as he had imagined.

In this world, there is no such thing as true "empathy". If you have not experienced anything yourself, you will never be able to understand the true emotions of the person who experienced it. Thinking about the girl's sadness and despair, Bai Song sighed and went to the office to look at the case materials.

Bai Song realized that he had to be more rational in order to solve the case. Unconsciously, Bai Song had grown up a little.

Often, when we think about why a person was killed, we usually have to consider two things: Who wants the victim to die? What is the motive and purpose for killing the victim?

Second, who benefits if the victim dies?

At present, if we consider one, then Sun’s debtor is the most suspicious, not the creditor. The creditors are still waiting to ask Sun for money, so why would they kill Sun?

Of course, the possibility of creditors cannot be ruled out, but debtors are more likely.

Although businessmen like Sun owe millions of dollars, there are still many people who owe him money.

If the second option is considered, the debtors will still be the ones who benefit, and those who owe money to Sun will most likely not have to pay it back.

In addition, Bai Song heard another thing.

A few days ago, Bai Song was on duty as a police officer. The place where the "aliens" were found opposite the Daguangli community was a slightly controversial bungalow area. Several households whose homes were being relocated were still negotiating with the developer. Simply put, they wanted more money.

Yesterday, news of a murder in Daguangli came out, and the developer immediately took the opportunity to spread the news: "A murder has occurred nearby. The feng shui of this place is not good. It does not meet the conditions for building a high-end residential area. The developer company plans to sell the acquired land use rights at a low price and prepare to evacuate."

When the well-informed residents heard the news, they all used their own skills to find the salesmen who contacted them and sold their houses to the developer at the previously negotiated price overnight.

Therefore, the developer is definitely the biggest beneficiary in Sun’s case.

Early the next morning, a large number of excavators and bulldozers rushed to the area. By nine o'clock in the morning, one-third of the wall of the area had been sealed off.

Bai Song is on duty. Today, Chief Wei and Chief Wang are out investigating a case, so Bai Song is following the team on a patrol mission.

The case is not progressing smoothly at the moment. Usually a homicide case can be solved within 24 hours or even within 8 hours. The difficulty will increase as time goes on. If the case continues to develop in this way, it is only a matter of time before a special task force is set up.

"Ding-ding-ding-ding-ding-ding-ding..."

A quick bell rang.

"What's the matter?" Bai Song watched Sun Tang and others getting ready to go out. He immediately put on his own police equipment and got ready.

"There is an emergency, usually a level 2 or higher." Sun Tang's face turned pale. This kind of ringing tone rarely occurs.

With the police reform in recent years, police incidents have been divided into different levels. Generally speaking, 99% of police incidents are level 4 incidents. Once a more urgent incident such as a group fight or someone injuring someone with a weapon occurs, it will be classified as a level 3 incident.

Level 2 police situation, it's already very serious.

Four or five people left the office in just over ten seconds. Deputy Director Wang Pei had also run down from upstairs. Master Sun, the police officer on duty at the front desk, handed a police dispatch form to Wang.

"There is a problem during the construction of the bungalow opposite Daguangli, please deal with it urgently"

"Sound the sirens, get going, quickly set up the cordon at the scene, and block traffic if necessary." After Wang said that, he got into a car.

The five or six people behind Wang Suo did not hesitate. They divided into two cars and followed Wang Suo, speeding all the way.

The police from Jiuheqiao Police Station arrived at the scene as soon as possible. The lights of the fire truck were flashing in the distance, and it was estimated that it would arrive in a few tens of seconds.

"What's going on?" Wang asked a leader at the scene.

"Hello, leader," the construction team leader shook hands with Wang, "It's a little after seven in the morning here, and we're following the national standards..."

"Get to the point." Wang interrupted him.

"One of our diggers, oh oh, it was an excavator, found an unidentified object when it was digging an old courtyard wall. Our safety captain saw it and didn't know what it was, so I ordered the work to be stopped and then called the police." The construction team leader pointed to the excavator ten meters away.

The nearby excavators and operating machinery have stopped working, and all the construction workers are not in their vehicles. It seems that this construction team still knows how to put people first.

"Where is it? Show it to me and I'll go take a look." Wang asked.

The construction team leader pointed in a direction, and Wang started to run away, but was stopped by Sun Tang. "I'll go over and take a look. I used to be a soldier."

Wang Suo glanced at Sun Tang and didn't refuse.

Sun Tang walked directly to the back of the excavator, held the handle of the vehicle, and stepped on the track.

After observing for about ten seconds, Sun Tang walked down quietly with an extremely ugly look on his face.

"How is it, Old Sun?" Wang Suo asked hurriedly.

At this time, the firefighters had arrived at the scene. When a group of firefighters were about to enter the scene, Sun Tang hurriedly stopped them.

"Expand the alert range and retreat." Sun Tang thought for a moment and said, "There is something wrong with this thing. I feel some danger."

"Dangerous?" Wang Suo looked in the direction Sun Tang pointed: "How dangerous is it?"

"I can't explain the specific situation clearly. We need more professional personnel to take a look at it." Sun Tang said.

"Okay." Wang Suo no longer hesitated and glanced at the road next to him. It was only about 20 meters away from this place. "Sun Tang, you direct them to set up a cordon around this area. I will inform the traffic department and block the traffic."

Under the captain's command, the firefighters quickly began to help Sun Tang and others set up a cordon and disperse the crowd. Bai Song took Sanmi into the area to check if anyone was still inside.

Because Bai Song had seen the "alien" here before and knew where he lived, Bai Song went to his residence as soon as possible. There was no one there, only some worn-out mattresses and some messy things.

"Sanmi, let's move these things to that place." Bai Song pointed to a big tree next to the flat land.

"What's there to move with all this junk?" Sanmi asked in confusion, "Aren't these all just garbage?"

"Yeah, but it's also someone's home." Bai Song stepped forward and started to move: "I asked the community police here, and I think they can arrange for this homeless man to go to a shelter in the next few days."

"Is this from a homeless person?" Sanmi nodded and went forward to help Baisong move it. After a while, these things were moved under the tree. This place should not be a problem for the time being.
