Chapter 226： Clue collection

It was four o'clock in the morning when we left the interrogation room.

The sky outside was the darkest time before dawn.

But, in another hour, the sun will rise and a new day will come.

In Chen Yan's view, Qin Jiangkai's confession is basically no problem.

In the process of answering questions, Qin Jiangkai has a clear thinking and correct logic.

Except for some temporal ambiguities, the other answers are more precise.

However, combined with Feng Ruihao's confession, both of them were at the end, thinking that the other party killed Ruan Xiaoqing.

Suppose Feng Ruihao didn't lie.

On the same day, the two made an appointment to meet in the pavilion in the back mountain of the Vocational and Technical College, but Ruan Xiaoqing missed the appointment and Feng Ruihao did not see Ruan Xiaoqing.

Then, after the 11th, the last person to see Ruan Xiaoqing was Qin Jiangkai.

Moreover, Feng Ruihao did not know the specific situation of Qin Jiangkai.

I don't know that he is single now, and I don't know that Qin Jiangkai is really interested in Ruan Xiaoqing, not just playing around.

Feng Ruihao had reason to suspect Qin Jiangkai of committing the crime.

Moreover, judging from the current situation, Qin Jiangkai was engaged in the slaughtering industry in his early years, and now he is opening a cold chain transportation company.

From this point, Qin Jiangkai has the ability to commit crimes.

But if what Qin Jiangkai said is true.

On the morning of the 11th, Ruan Xiaoqing did leave Qin Jiangkai's house.

And I went to the back mountain of the Vocational and Technical College and met Feng Ruihao.

What will happen when the two meet?

Nothing but a big fight.

Ruan Xiaoqing has already proposed to Feng Ruihao to break up.

In Ruan Xiaoqing's heart, now Feng Ruihao is just an ex-boyfriend.

The two had nothing to do with each other half a month ago.

She is now with Qin Jiangkai, and there is neither moral restraint nor legal prohibition.

Ruan Xiaoqing is single, and Qin Jiangkai is divorced and single.

When two people are together, it is only natural that no one can control it.

Of course, this is just Ruan Xiaoqing's idea.

In Feng Ruihao's view, the two did not break up.

Ruan Xiaoqing was only deceived by Qin Jiangkai with money.

However, now Ruan Xiaoqing did not see through Qin Jiangkai's ugly face and conspiracy.

However, Feng Ruihao didn't know, Ruan Xiaoqing might have already understood everything.

Compared with Qin Jiangkai, who is gentle, gentle and courteous, and rich in wealth, in Ruan Xiaoqing's heart, Feng Ruihao has no advantage.

At Qin Jiangkai's house, Ruan Xiaoqing's phone was connected because the phone was connected by Qin Jiangkai who was in a state of excitement.

Also, hands-free calling is turned on.

At that time, Ruan Xiaoqing did not stop it.

This shows that Ruan Xiaoqing at that time didn't care about Feng Ruihao for a long time.

This scene is very similar to a TV series called Snail House that Chen Yan watched in his previous life.

Ruan Xiaoqing is like Guo Haizao in the TV series, Feng Ruihao is Xiaobei, and Qin Jiangkai is another Song Siming.

The difference is that Ruan Xiaoqing and Qin Jiangkai are more moral.

Because, on the evening of the 10th, when the two had a relationship, both of them were single.

Therefore, no matter from which point of view, Qin Jiangkai's suspicion of Feng Ruihao's passion for murder is justified.

What's more, Feng Ruihao is a chef, and he is fully capable of disposing of the corpse into the present state.

8 am on the 20th.

In the conference room, Chen Yan presided over the case analysis meeting.

"Through the surprise inquiry last night."

"We now have two important suspects... Feng Ruihao and Qin Jiangkai."

"The two now identify each other as the murderer who killed Ruan Xiaoqing and Sui Shi Fo Shi."

"Now, the confessions of the two have to be screened and confirmed," Chen Yan looked at Lan Feng: "Lan Feng, you can handle this matter."

Last night, it was Feng Ruihao and Qin Jiangkai, who were interrogated by Lan Feng and Chen Yan. They were the most clear about the ins and outs of their confessions.

Lan Feng nodded: "Yes, team leader."

Chen Yan nodded and warned again: "Focus on the investigation. After 10 o'clock on the 11th, Ruan Xiaoqing left the elevator surveillance video of Qin Jiangkai's residence."

"And the monitoring of her appearance in the community, and finally, what kind of transportation she took, how she left Qin Jiangkai's residence, and other information, we must investigate clearly."

"clear!"

This point, Lan Feng is very clear.

Finding out how Ruan Xiaoqing left the community where Qin Jiangkai lived is an important evidence to rule out Qin Jiangkai's suspicion of committing the crime.

After confirming this, it is necessary to find out whether Ruan Xiaoqing went to the pavilion in the back mountain of the Vocational and Technical College.

Judging from the information so far, there is no video in the park on the mountain behind the college.

However, the absence of video surveillance on the mountain does not mean that there is no video surveillance down the mountain.

Moreover, Ruan Xiaoqing was about 5 kilometers away from Qin Jiangkai's community to the mountain behind the college.

Walking is definitely impossible.

When the weather is freezing cold, Ruan Xiaoqing has the highest probability of taking a taxi or taking a bus.

If Lan Feng could find Ruan Xiaoqing to leave Qin Jiangkai Community, the entire trajectory chain to the mountain behind the college.

Then, Feng Ruihao said that he had not seen Ruan Xiaoqing that day, so he was probably lying.

"Next, Chaoyang and Zhao Bing will report the situation respectively."

"Yes!"

Early this morning, Zhang Chaoyang and Zhao Bing had returned.

In the first case analysis meeting, the two were responsible for investigating the information of the slaughterhouses, restaurants, and cold storages around the college, as well as the investigation of the college video.

At present, basically there is a more detailed investigation result.

Zhang Chaoyang first reported.

"Team leader, in the past two days, our group has conducted a detailed survey of all restaurants, cold storages, and slaughterhouses within three kilometers of the college."

Zhang Chaoyang operates the projection: "This is a form involving related places."

"Restaurants, we focus on those with refrigerators. There are 95 restaurants in total."

"With the Vocational and Technical College as the center, it radiates all around."

"The chefs of these 95 restaurants were visited and the freezers were checked."

"However, nothing suspicious was found."

On the projection, it is the relevant investigation situation.

First, the reason why the distance is set at three kilometers is because of the convenience of soaking.

Ruan Xiaoqing disappeared on the morning of the 11th, and the earliest time the body object was thrown was on the evening of the 15th.

It can be said that the murderer has four days to commit the crime.

Killing, freezing corpses, disposing of and soaking wet.

Although the body cannot be recovered at present, the entire body has basically been collected.

In other words, after the murderer lost Ruan Xiaoqing, all the dead bodies, bones, etc. were soaked in Anbei Vocational and Technical College.

From the night of the 15th to the 17th, the murderer basically did not stop.

Judging from this clue, the murderer is either in the academy, and it is very convenient to get wet.

Another is near the college.

Three kilometers is generally the maximum range of activities a person can walk.

Second, according to Chen Yan's request, Zhang Chaoyang made a key investigation on whether the chefs of these restaurants asked for leave.

Because the murderer started committing crimes on the 11th, and began to get wet on the 15th.

From the night of the 15th to the night of the 17th, it was soaked continuously. During this time period, if the chef committed the crime, his crime time could not be guaranteed.

After all, most chefs' jobs start late in the morning.

At 10 o'clock in the evening, or even 11 o'clock, there are people who get off work at 12 o'clock.

All, if it is a chef, then he can only take time off to commit crimes.

"These 95 restaurants have a total of 259 chefs."

"From the 11th to the 17th, there were a total of 3 people who asked for leave, and 18 people who asked for leave intermittently during the period."

"We conducted a detailed investigation of these individuals."

Zhang Chaoyang changed a projection: "Three people who have been absent, two of them are seriously ill parents, one is going to get married, and they all returned to their hometowns, not in Anbei City."

"We have contacted the local detective team to verify this."

"The other 18 people and one person, the longest leave of 3 days, was a minor operation in the hospital."

"The other 17 people asked for leave for half a day or a day."

"However, after the investigation, there is basically no time to commit the crime."

Click.

"This is the freezer inspection record of 95 restaurants."

"A total of 175 freezers."

"There are 158 in use, and there is no recent cleaning record for all of them."

"The technical department has tested the refrigerated residues and found no blood or tissue residues in Ruan Xiaoqing."

Chen Yan nodded, Zhang Chaoyang's group had a lot of work, but the work was meticulous.

If the corpse of Ruan Xiaoqing was stored in the cold storage, it is very likely that after all the corpses were disposed of, they were cleaned.

However, in general restaurants, the freezer will not be washed once from the time the freezer is bought until it is worn out or the restaurant closes down.

"158 freezers..."

"Have you checked the remaining 17 freezers?"

Zhang Chaoyang nodded: "Also checked."

"The earliest damage was a month and a half ago."

"It has been verified with the staff of the relevant hotel, and there is no doubt."

Zhang Chaoyang's group has the most people.

Liu Biao, captain of the Anbei City Detective Team, assigned 50 people to Zhang Chaoyang and the others.

It was only then that the hotels within three kilometers were lined up in two days.

However, it now appears that the possibility of the hotel staff committing the crime is basically ruled out.

"How about the slaughterhouse and the grim investigation?"

Zhang Chaoyang still shook his head: "The location of the Vocational and Technical College is close to the city center, and there is no slaughterhouse nearby."

"However, we checked the raw meat sales points in the nearby farmers' market."

"It is still three kilometers as the limit, and we have checked all the raw meat sales outlets."

"There are 6 outlets in total."

"However, we have checked all the personnel and frozen meat freezers at the outlet."

"It's the same as the result of the hotel's survey, there is no doubt."

Zhang Chaoyang sighed and continued: "As for the cold storage, we have also conducted an investigation."

"Including supermarket cold storage, logistics station transfer cold storage and a cold chain transfer station two kilometers away."

"We have all conducted investigations, and have carried out sample inspections of the cold storage ~ www.novelhall.com ~ cold chain transfer station, management is standardized, and there are bills for entry and exit, eliminating suspicion."

"The cold storages of the five large supermarkets have administrators, and they are only stored at low temperature and cannot be refrigerated."

"There are also 7 logistics stations in transit, with 7 freezers and 1 small cold storage."

"None of them have the function of freezing."

Zhang Chaoyang's investigation has been very detailed.

Three kilometers outside the school, basically all places where it is possible to freeze and dispose of corpses have been checked.

Now, the rest is also the most important location to touch the row.

Zhang Chaoyang has not reported yet.

And this is what Chen Yan is most concerned about.

"How is the investigation of the cafeteria and restaurant on campus?" 18428/10552307
