Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

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.

“We can’t pin all our hopes on face comparison.”

The cases Li Donglin handles are all major and important.

They are extremely experienced, especially the three criminal suspects in this murder case. They act very cautiously and have a strong sense of counter-reconnaissance.

Therefore, it must be very difficult to discover the identity of the other party through face comparison, or even catch the other party.

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

"The other party is obviously not staying in Tianzhou City for only one or two days. Where is the other party's location? Follow the clues that there is criminal suspect No. 3 in Wang Song, 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.

In the car.

Wang Ruiqing was still reading about Lu Chuan.

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

Although Qin Hui remained silent, after getting into the car, he sat in the passenger seat and looked forward without speaking to Lu Chuan, making his attitude clear.

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

There is indeed something wrong with the way this inquiry was conducted.

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?"

in accordance with?

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

Yes, that’s what Xi Mengyao said.

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 the 116 case back then. He had a very clear evidence chain of the case that year, and there was no other evidence.

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

"This one……"

Wang Ruiqing was asked: "There is no other evidence. The reason why the case has not been solved until now is because the crime scene was very clean and nothing was left."

"So, at that time 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 detective, it is important to always be suspicious of anyone involved in a crime.

Xi Mengyao... As the victim and the only survivor of this case, Qin Hui and others introduced 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 he didn't.

After all, when Xi Mengyao answered Lu Chuan's inquiry just now, 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 was vague, except 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.

"not sure for now."

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

"It's...Xi Mengyao."

"Drinking?"

"Drink."

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

"Given the drinking capacity of these girls, they were actually at least half drunk when they returned to the dormitory."

"So, this explains why when the suspect entered the dormitory, no one responded, 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."

"A phenomenon was discovered."

The reason why Lu Chuan wanted to see the corpse from that year was because 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 crime traces at the scene can clearly identify three suspects."

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

Qin Hui knew what Lu Chuan said.

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 couldn't do it during the murder case?"

This is indeed a problem.

It was not the first time that the criminal suspect committed a crime. He must be a repeat offender who committed crimes continuously. Since he could leave no trace at the crime scene of Case 1, he could 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.

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