Chapter 578 Lu Chuan’s Questions


When Wang Song made a discovery, Tianzhou City's current survey team immediately started face comparison work.

With the advancement of criminal investigation technology, face comparison has become more frequent and plays an increasingly important role in case detection.

In many cases, when other technologies fail, face comparison can often bring new directions to the investigators.

However, like fingerprints, face comparison requires a huge database to support it.

This aspect is often lacking.

"You cannot place all your hopes on face comparison."

The cases handled by Li Donglin are all major and important.

Extremely rich experience, especially the three suspects in this murder case, are very cautious in their actions and have a strong sense of anti-reconnaissance.

So it must be very difficult to discover the identity of the other person or even catch the other person through face comparison.

"Old Song, you can't relax here and try to find clues about suspects No. 1 and 2."

"The other party obviously didn't stay in Tianzhou City for only a day or two. Where did the other party stay? Follow the clues that there is criminal suspect No. 3 in Wang Song's area. Catch him and try to find the place where the other party is hiding."

This is a game of following the clues. The criminal suspect tries to cut off all traces left by himself, and the police tries to find the suspect through the clues.

The progress on Wang Song's side is relatively large, and the progress on Lu Chuan's side is also not small.

On the car.

Wang Ruiqing is still thinking about Lu Chuan.

"Xi Mengyao... is he a survivor or a victim of the 116 case? Officer Lu, you just asked that... it's not good."

Although Qin Hui didn't speak, after getting in the car, he sat in the passenger seat Driving, looking straight ahead, he made his attitude clear without speaking to Lu Chuan.

Although Lu Chuan was of great help to the QZ City Criminal Investigation Detachment,...

There was indeed something wrong with the way of questioning this time.

Lu Chuan smiled.

Look at Wang Ruiqing carefully.

"Brother Wang, in the 116 case back then, the police determined that there were three suspects. Is there any basis for this?"

Basic?

Wang Ruiqing was startled: "Yes, Xi Mengyao said it."

Yes, it was Xi Mengyao who said it.

As the victim and the only survivor, Xi Mengyao identified three suspects based on her confession.

But what about other than this?

“Is there any other evidence?”

Other evidence?

Wang Ruiqing participated in the on-the-spot investigation of Case 116. He has a very clear evidence chain of the case and there is no other evidence.

"For example, footprints, fingerprints, hair, dander, etc."

"This..."

Wang Ruiqing was asked: "There is no other evidence. Why is the case so far?" It was not solved because the crime scene was very clean and nothing was left behind. "So, you just judged that there were three suspects based on Xi Mengyao's words?"

Lu Chuan asked back, making Qin Hui's head buzzing as he sat in front of him!

To be able to achieve the position of captain of the QZ City Criminal Investigation Detachment, Qin Hui is definitely not a loser.

On the contrary, Qin Hui will have rich experience in handling cases, keen intuition for handling cases, and rigorous logical thinking and analysis skills.

As a criminal police officer, it is important to always be suspicious of anyone involved in a case.

Xi Mengyao... As the victim and the only survivor of this case, Qin Hui and others brought her into a believable role from the beginning.

However, who can guarantee that what Xi Mengyao said must be true?

Just like the question Lu Chuan just raised, there are three suspects, and this was all said by Xi Mengyao.

But in fact, no evidence was left at the crime scene. Who can say that it must be three people? What if Xi Mengyao lied?

Wang Ruiqing reacted at this moment and looked at Lu Chuan in surprise.

"Lu Chuan...you mean...Xi Mengyao lied?"

lie?

Lu Chuan shook his head.

Xi Mengyao may have really lied, but maybe she did not.

After all, when Xi Mengyao just answered Lu Chuan's inquiry, or even when she answered the police's inquiry that year, she did not use affirmative language to say that she did see three people.

Her language expression was vague, she just said that she might just have an impression or an impression.

There is no certainty that there must be three people.

So, for Xi Mengyao, who was already in a daze at the time, was what she saw true?

Who can guarantee it?

Qin Hui, who was sitting in the front row, also turned around at this moment. He now understood why Lu Chuan asked Xi Mengyao in such a tone just now.

Because Lu Chuan was skeptical of her.

"Lu Chuan, what do you mean..."

Qin Hui didn't say it clearly, but both Lu Chuan and Wang Ruiqing knew what he was going to say.

“It’s not sure yet.”

“I remember that on the day the case occurred, six girls in the dormitory went out to eat together to celebrate their birthday. Whose birthday was it?”

"It's...Xi Mengyao."

"Drinking?"

"Drinking."

"The file says that you investigated the restaurant where 6 girls ate. According to the consumption records at that time, the 6 girls drank at that time. I bought more than thirty bottles of beer.”

“With the amount of alcohol these girls had, they were actually at least half drunk when they returned to the dormitory.”

“So, this is the explanation. Why did no one react when the suspect entered the dormitory, but was easily stunned by the suspect, right?"

Wang Ruiqing and Qin Hui nodded.

"Another point, this morning, I saw the bodies of the two victims that were not cremated."

"I discovered a phenomenon."

The reason why Lu Chuan wanted to see the The reason is that the suspects in this case and the family massacre in Tianzhou City were committed by the same group of people, or at least a common suspect.

“In the Tianzhou City massacre case, the criminal suspect also violated the female victim.”

"The traces of the crime at the scene can clearly identify three suspects."

"One of them is one of the suspects in the QZ City 116 case."

What Lu Chuan said, Qin Hui knew .

This is also the reason why Lu Chuan came to Qinzhou.

“Since the two cases have the same murderer, why was it that the murderer was able to leave no trace at the scene during the 116 case, but not the murder case?”


This is indeed a problem.

This is not the first time that the criminal suspect has committed a crime. He must be a repeat offender who has committed crimes continuously. Since he can leave no trace at the crime scene of Case 116, he can also leave no trace at the crime scene of Case 116. .

But in fact, although there were no skin flakes, hair or other information that could identify the suspect's DNA at the scene of the murder case, the footprints were messy, leaving some clues for the public security organs to handle the case.

Lu Chuan also identified the suspect's physical characteristics through the footprints. Song Mingguang and Wang Song also made breakthrough progress in the case based on the physical characteristics given by Lu Chuan. (End of this chapter)
