Police Detective

In a murder case, the simplest one is to find an opportunity and stab him to death. For those with a little intelligence, such as poisoning, there are several steps.

For example, first prepare a colorless and odorless poison, put it into the water that the deceased drank, and then let the deceased drink it without warning.

The more famous cases, such as the heavy metal thallium poisoning case, are still unsolved because there is insufficient evidence, although some people are highly suspected.

A slightly more complicated murder case requires several steps to be calculated, and the best people will find ways to design unexpected events.

Take this case for example - if it was really murder.

There was a coincidence in this case, that is, the deceased had a heart attack and died directly from the fire.

According to Sun Jie, this was not a bomb after all, it was just a momentary explosion. The person could not die. At least there was a possibility of rescue.

"If this is murder, we must make sure to kill him," Bai Song said to everyone: "From here on, the murderer will have other tricks, such as trying to delay the time on the way to the hospital. Or, on the same day, Get the deceased as drunk as possible at night.”

"This is an idea." Detachment Zhuang nodded.

Detachment Liu from Xijing Branch frowned and said, "Are we making this matter too complicated?"

Detachment Liu looked at Bai Song: "Inspector Bai, don't think that everyone is as smart as you."

"I wonder what Detachment Liu means here?" Bai Song asked.

"Don't get me wrong." Detachment Liu said: "Not everyone is as professional as you. I think that if this is a murder case, then the murderer might think that this will definitely kill Yao."

"What you said makes sense." Bai Song nodded: "Can you elaborate?"

"If it is the murder of an outsider or the murder of the suspect's children, the design may be more elaborate. But these water cats, it's not that I look down on them. We have encountered water cats in recent years who kill the boss. Most of them are directly Stabbed to death." Detachment Liu said.

"Hmm." Bai Song thought thoughtfully.

Bai Song understood what Detachment Liu meant. There was no need for workers to kill their bosses. If they did, they wouldn't get any money. They might have to pay with their lives. In most cases of workers killing their bosses, they went to force the bosses to demand wages. In the end, they got angry and blood-spattered, causing a tragedy. Rarely did they act with a plan and simply wanted to kill the person.

"Having said all that, if someone was murdered, what was the motive?" Zhuang detachment interrupted everyone.

This is actually the key to handling the case. Everyone knows that murder cases are not simple cases.

"We have to expand the search area for this. Yao is quite a loner. This time he invited everyone to dinner. He also took the initiative to organize the meal for the start of the new project." Detachment Liu asked: "This Boy, how far do you have to offend someone for something like this to happen?"

What Detachment Liu is talking about is also in the category of criminal psychology.

Many veteran detectives don't know the name of a certain theory, but they still have enough understanding in practice.

In the court's judgment, if other circumstances of the case are the same, murder with premeditated murder will be punished more severely than murder with passion.

The reason for this difference is that the subjective viciousness of deliberate murder is more serious than that of passionate murder. For example, if a worker asks his boss for wages and is forced to commit murder, he does it just for the money. If the boss gives him the money, he will be fine. The subjective viciousness is slightly weaker; and for premeditated murder, other circumstances are not considered at all, "I just want to do it." "I'll kill you" is more subjective and vicious.

Therefore, deliberate murder with a certain design is highly likely to be based on deep hatred.

"From this perspective, I am more inclined to shift the direction of the murder investigation to Yao's ex-wife, children and several closest friends, because deep enough hatred cannot be formed in a day or two." Bai Song said : "Although it was my daughter who called the police and my son asked us to open a case for investigation, we cannot rule out the suspicion of the two."

"I support Inspector Bai's statement." Detachment Liu nodded: "We have to intensify our efforts to investigate Yao's life."

"I want to find his children again to ask about the situation." Bai Song said.

"Okay." Detachment Liu looked at his watch: "It's already past midnight and his children are gone. They will definitely come back tomorrow. There's no need to call them. It saves us a psychological defense line on the way."

"It's up to you."

People from the headquarters and the local detachment continue to conduct joint investigations.

As the investigation of the case unfolded, Bai Song still tried to investigate his previous thoughts.

That is: if the murderer felt that Yao was not necessarily dead, what other tricks would he have?

After careful investigation, the situation was actually discovered.

One of the deceased's bank cards was frozen just last night!

"What could this be?" Liu Shuyuan yawned: "I asked the bank for help in the middle of the night, but it took a lot of effort."

"How did it freeze?" Bai Song asked.

"It was caused by entering the wrong password multiple times through online banking." Liu Shuyuan explained.

"Is it possible that someone hopes that Yao will go to the hospital and have no money to stay?" Wang Liang's eyes lit up: "This is the back-up plan Bai Song said!"

"Impossible." Bai Song shook his head: "I know that Yao can't unfreeze himself when he is injured, but in fact, the hospital cannot ignore this situation. Many people think that the hospital is dead. The hospital is not a charity if it requires money, but when the hospital is facing acute trauma such as traffic accidents, it cannot just ignore the situation because of lack of money."

"Bai Song," Sun Jie thought for a while: "I think what Detachment Liu just said is right. Don't put your thoughts on the murderer. Maybe the murderer really thinks that this will make the hospital refuse to save him."

After saying that, Sun Jie glanced at Wang Liang, and then said to Bai Song: "For example, Wang Liang doesn't know about this kind of thing."

"Who said that?" Wang Liang said stubbornly, holding his neck, "I'm just trying to attract others!"

"Then we have to check whether Yao's other cards have been frozen in the same way." Bai Song said: "The people who can know his card number must be relatively familiar with him, either his children or people with him. Someone with a transfer record.”

"This is the only bank I'm familiar with. As you know, other people's systems are shut down at night, so you can't just find the bank's staff on duty." Liu Shuyuan said, "Let's wait until tomorrow."

"A lot of things have to wait until tomorrow." Bai Song felt a little impatient for no reason, "Soldiers need to be quick."

"Then what do you say, we will listen to you." Sun Jie said.

"I still have to start from the beginning. I have to know how this person died and how he exploded." Bai Song put the problem on the table: "First of all, we have to understand what explosives are, and we have to solve the case before dawn. ”
