Mu Yuan's expression did not change in any way because of Captain Ming's explanation, he still frowned deeply, and said, "But...... I think there are some problems in this case. ”

"What's the problem?"

"In a normal robbery and murder case, is the suspect rushing to kill someone?" asked Mu Yuan with a serious face.

"Of course it can't be!" Captain Ming said, "In a robbery and homicide case, the suspect's motive is robbery, and the reason why it eventually turns into a robbery and murder case is mostly because the victim resisted or did something that made the murderer feel that he was threatened. Generally speaking, if it is just a robbery, the suspect will not go to the step of murder. With the exception of some crazy people, of course. ”

Mu Yuan nodded and said, "That's right, so I think it's very strange." From the scene of this case, I can see that the suspect did not express the purpose of the robbery at all, and directly started to kill. A person, if it was really just a robbery, would do it?"

When everyone in the research room heard this, they all raised their heads and looked at Mu Yuan in a daze.

Captain Ming was a little surprised and asked, "Detachment Mu, how did you see that the suspect killed directly?"

What he said was not questioning, but purely humbly seeking advice.

There's no way, it's the big demon king of the police world sitting opposite, not everyone has the courage to question it.

Mu Yuan responded calmly: "The scene of this case is very simple, judging from the situation at the scene of the crime, the murderer directly compared the dagger to the driver's neck, in this case, as long as the murderer expresses the purpose of asking for money, the driver will definitely not have any hesitation and take out all the money." According to the statements of the deceased's family, the driver carried a leather bag, and the cash received and the change prepared were all placed in the purse. It was also very easy for him to hand the bag to the back row. But in fact, the murderer did not get the money from the driver, but after killing someone, he opened the driver's door and took the driver's purse. This handprint on the front doorknob also confirms this. ”

"It could also be that the murderer put down the dagger and prepared to leave after getting the purse, and some of the driver's behavior made the murderer suspicious, and then killed the murderer? As for the blood stains on the doorknob of the front door, it may also be that the murderer suspected that the deceased still had property on him, so he opened the car door and searched ......."

Speaking of this, the Ming brigade suddenly stopped, and he frowned, as if he was remembering something.

Director Wu on the side also experienced the investigation of the case, and when he heard the conversation between Mu Yuan and Ming Jianlin, a flash of inspiration flashed in his mind, and at this time, the Ming Brigade paused, and he immediately said: "Judging from the blood stains on the deceased's body, he should not have been searched on his body, so it is impossible for him to open the car door to search for the deceased's property." And even the storage compartment next to the door showed no signs of rummaging. ”

"So...... He opened the car door, either to see if the other party was dead. Either...... It's to take the leather bag. ”

Director Wu's last sentence made the entire conference room fall silent.

Obviously, in a normal robbery and homicide, the killer is unlikely to confirm that the target is dead or not - and that it is not an intentional murder before fleeing the scene.

Therefore, whether it is to open the door to confirm whether the driver is dead, or to get the purse, its behavior is very suspicious.

Mu Yuan said: "Now, robbery is a fact! The suspect did take the purse containing the cash. But what about murder? If our inference is true, then robbery is probably no longer the sole purpose of the murderer, and murder is not for robbery. In addition, the hoods, gloves, daggers, etc., which he prepared, all show that everything he did was planned. If he just wanted to rob in the first place, the chances of it turning into murder are low, unless ...... He was going to kill in the first place. ”

The case room remained silent, so quiet that it seemed to be able to hear a person's heartbeat.

Mu Yuan's reasoning opened a door for everyone.

If...... This case is not a robbery and murder, but an intentional homicide, so will there be a very different outcome?

Obviously, the answer is yes.

At the beginning, the Qingyu County police directly characterized the case as robbery and murder because of various factors at the scene, and all the reconnaissance plans were also in accordance with this line.

But what if this initial assumption is wrong?

Robbery and homicide and intentional homicide are two completely different cases, and the investigation ideas are also completely different.

The robbery is a crime of passion and is aimed at an unspecified target.

In the process of investigation, such cases can only be further investigated according to the clues at the scene or in the surrounding area, and cannot be solved through the analysis of causal logic, which also makes it difficult to solve this kind of case.

In intentional homicide, there must be a certain relationship of grievances and hatred between the murderer and the deceased, and the case can be solved by analytical reasoning.

The Ming Brigade also had some recognition, but still raised their own questions: "However, judging from the previous situation, it is very likely that the murderer and the deceased driver did not know each other." If they knew each other, they wouldn't have stopped for so long when they got on the bus, and even if they had something to talk about because they knew each other, they would get in the car and talk while walking. ”

Mu Yuan said seriously: "Captain Ming, I also agree with what you said. But the fact that they don't know each other is limited to the fact that the deceased driver didn't know the murderer, which doesn't mean that the murderer didn't know the driver. ”

As soon as these words came out, the eyes of the Ming Brigade suddenly lit up.

Yes, intentional homicide does not have to be known to the deceased.

As long as the murderer knows the deceased.

There are even some homicides, the deceased not only does not know the murderer, but also does not know when he has a grudge with someone.

Director Wu unconsciously tapped his fingers on the table, and said, "I agree with the opinion of the Mu detachment, we were ...... Sloppy. Although we had good reasons for characterizing the case as a robbery and homicide at that time, we should not cut off other paths. If we had followed this direction at the time, we might have made new discoveries. ”

Mu Yuan said seriously: "It's not too late!"

Director Wu glanced at Mu Yuan, he really admired Mu Yuan's confidence!

It's nice to be young!

Mu Yuan said again: "But now the determination of the motive for the murder is only an inference, we will first investigate in this direction, and then make adjustments according to the actual situation encountered." ”

Naturally, no one else will have any more opinions.

Originally, Director Wu and others thought that the detection of this case was that the people in Qingyu County had a higher composition of soy sauce, after all, this matter also had a criminal record in the past, as long as it was a case in which Mu Yuan participated, the sense of existence of other people was super low.

But now, because Mu Yuan changed the direction of the investigation of the case as soon as he came up, it is equivalent to completely overturning the previous set, which has produced a lot of work.

One of the most important is to conduct a survey to sort out the interpersonal relationships of the deceased before his death, who he had grudges with, and then sort out and investigate them one by one.

This work is definitely not something that Mu Yuan can do alone.

"Mu detachment, look...... Why don't you go to our county bureau? After all, the follow-up reconnaissance work will be carried out in Qingyu County. Director Wu said.

"No problem!" Mu Yuan agreed directly.

In fact, the venue of the meeting was set at the city bureau today, mainly because the leaders "overestimated" Mu Yuan's ability, and also misestimated the judgment of the Qingyu County police on this case, thinking that as long as Mu Yuan carefully consulted the file and then gathered the people who were familiar with the case to discuss it, Mu Yuan would most likely be able to put forward constructive suggestions and promote the detection of the case.

As a result, Mu Yuan did put forward constructive suggestions, but he directly rejected the results of the previous investigation and visit.

Everything goes back to the original point, and all of them are indispensable.

However, these works must be carried out only after returning to Qingyu County.

In this regard, the Gong detachment also did not have any opinions.

In the final analysis, Qingyu County's criminal investigation work is also part of Xihua City's criminal investigation work, isn't it? The Gong detachment naturally hopes that this case can be solved as soon as possible.

Later, the Gong detachment reported the relevant situation to the Feng Bureau, who had already "walked home", and when the Feng Bureau learned of this result, although he felt a little depressed, he was still very relieved that Mu Yuan could make such a breakthrough discovery when he got the case.

As for Mu Yuan's command, he went to Qingyu County to guide and solve the case, Feng Ju also agreed with both hands - as long as it was not someone else's responsible field, he didn't have any opinions.

After the matter was decided, the Qingyu County delegation led by Director Wu was ready to set off.

They came by car, so it was easy to go back.

Director Wu was originally going to invite Mu Yuan to go back in his car, but Mu Yuan refused.

Mu Yuan is ready to drive, so it will be more convenient to come back.

But just as he was about to get the keys to drive the Camry, the phone rang.

Seeing this number, Mu Yuan was really stunned, because this was Gu Jun's phone.

Although it was a little strange, Mu Yuan still connected.

"Team Mu, it's me! ”

"I know. What's the matter?"

"Team Lin said that you need to go to Qingyu County to guide the case, and let me come and drive you. Gu Jun said seriously.

Mu Yuan's eyelids jumped, this is ...... What's the situation?

You said that I went to Leya City to guide the case, and it was reasonable for you to send a car to send me to the provincial department, after all, this is in the name of the provincial department to guide the case, but now I am going to Qingyu County, and I am still the captain of the Xihua City Serious Crime Brigade, what do you mean by the provincial department sending a car?

This kind of thing...... Deputy Captain Lin shouldn't be able to do it, right?

Suddenly, Mu Yuan's heart moved, and he thought of a possibility.

But right now, Gu Jun's phone hasn't hung up yet, and the other party has already come over, so he can't ask others to go back, right?

"Okay! Wait a minute, I'll be right out. ”

If it goes on like this, it won't be long before this Gu Jun will soon become his full-time driver......
