Chapter 227: Clues Gathering (Seeking Tickets)

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

The sky outside was just before dawn, the darkest time.

However, in another hour, the sun will rise and a new day is coming.

Qin Jiangkai's confession, in Chen Yan's opinion, basically has no problem.

In the process of answering questions, Qin Jiangkai's thinking is clear and his logic is correct.

Except for some ambiguity in time, other answers are relatively accurate.

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

Assuming that Feng Ruihao did not lie.

On that day, the two agreed to meet in the pavilion on the back mountain of the Vocational and Technical College, but Ruan Xiaoqing broke the appointment and Feng Ruihao did not see Ruan Xiaoqing.

So, 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.

He did not know that he was single now, and he did not know that Qin Jiangkai was indeed interested in Ruan Xiaoqing, and it was not just a pure play.

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

Moreover, from what has been discovered so far, Qin Jiangkai worked in the slaughtering industry in his early years, and now he has opened a cold chain transportation company.

From this point of view, Qin Jiangkai has the ability to commit a crime.

But if what Qin Jiangkai said is true.

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

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

What will happen when the two meet?

It's nothing more than a big quarrel.

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

In Ruan Xiaoqing's heart, Feng Ruihao at this moment 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 no moral constraint or legal prohibition.

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

It is natural for two people to be together, and 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 just deceived by Qin Jiangkai's money.

However, Ruan Xiaoqing has not seen through Qin Jiangkai's ugly face and conspiracy.

However, Feng Ruihao does not know that Ruan Xiaoqing may have seen through everything.

Compared with the gentle, polite and wealthy Qin Jiangkai, in Ruan Xiaoqing's heart, Feng Ruihao has no advantage.

At Qin Jiangkai's house, Ruan Xiaoqing's phone was connected because the call was answered by Qin Jiangkai in an excited state.

Moreover, the hands-free call was turned on.

But Ruan Xiaoqing at that time did not stop it.

This shows that Ruan Xiaoqing at that time no longer cared about Feng Ruihao.

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 night of the 10th, when the two had sex, both were single.

So, no matter from what angle, Qin Jiangkai's suspicion that Feng Ruihao killed someone in passion is reasonable.

What's more, Feng Ruihao studied cooking and was fully capable of treating the body as it is now.

At 8 am on the 20th.

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

"Through the surprise questioning 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 lost her body."

"Now, we need to identify and confirm the confessions of the two," Chen Yan looked at Lan Feng: "Lan Feng, you go and do this."

Last night, it was Lan Feng who interrogated Feng Ruihao and Qin Jiangkai with Chen Yan, and he knew the ins and outs of the confessions of the two most clearly.

Lan Feng nodded: "Yes, team leader."

Chen Yan nodded and reminded again: "Focus on checking the elevator surveillance video of Ruan Xiaoqing leaving Qin Jiangkai's residence after 10 o'clock on the 11th."

"And the surveillance of her appearance in the community, and finally, what kind of transportation she took, how she left Qin Jiangkai's residence, and other information, all need to be investigated clearly."

"Understood!"

Lan Feng was very clear about this.

Finding out how Ruan Xiaoqing left Qin Jiangkai's residential area is an important piece of evidence to exclude Qin Jiangkai's suspicion of committing a crime.

After confirming this, the next step is to find out whether Ruan Xiaoqing went to the pavilion on the back mountain of the Vocational and Technical College.

From the information currently available, there is not much video in the park on the back mountain of the college.

However, the lack of video surveillance on the mountain does not mean that there is no video surveillance at the foot of the mountain.

Moreover, Ruan Xiaoqing is about 5 kilometers away from Qin Jiangkai's residential area to the back mountain of the college.

It is definitely impossible to walk.

In the cold weather, Ruan Xiaoqing is most likely to take a taxi or a bus.

If Lan Feng can find the entire trajectory chain from Ruan Xiaoqing leaving Qin Jiangkai's residential area to the back mountain of the college.

Then, Feng Ruihao is likely to be lying when he said that he did not see Ruan Xiaoqing that day.

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

"Yes!"

This morning, Zhang Chaoyang and Zhao Bing have returned.

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

At present, we basically have a more detailed investigation result.

Zhang Chaoyang reported first.

"Team leader, in the past two days, our team has conducted a detailed investigation 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 are focusing on the ones with freezers. There are 95 in total."

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

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

"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 in water.

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

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

Kill someone, freeze the body, dispose of it and soak it.

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

In other words, after the murderer lost Ruan Xiaoqing at the age of 18, all the body parts, bones, etc. were soaked in Anbei Vocational and Technical College.

From the night of the 15th to the 17th, the murderer basically continued without interruption.

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

The other one is near the college.

Three kilometers is generally the maximum range of movement for a person to walk.

Second, Zhang Chaoyang followed Chen Yan's request and conducted a key investigation into whether the chefs in these restaurants had asked for leave.

Because the murderer started committing crimes on the 11th and started getting wet on the 15th.

From the night of the 15th to the night of the 17th, we soaked continuously. During this time period, if the chef committed the crime, his time to commit the crime cannot be guaranteed.

After all, most of the chef's work starts in the late morning.

At around 10 o'clock in the evening, some even get off work at 11 o'clock or 12 o'clock.

Therefore, if he is a chef, he can only take time off to commit the crime.

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

"From the 11th to the 17th, a total of 3 people took leave, and 18 people took leave intermittently during this period."

"We conducted a detailed investigation into these individuals."

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

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

"One of the other 18 people took leave for the longest time, which was 3 days, for a minor operation in the hospital."

"The other 17 people usually take half a day or one day off."

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

Click.

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

"There are 175 freezers in total."

"There are 158 in use, and there are no recent cleaning records for any of them."

"The technical department has tested the refrigeration residue and found no traces of Ruan Xiaoqing's blood or tissue residue."

Chen Yan nodded. Zhang Chaoyang's team had a heavy workload, but the work was very detailed.

If Ruan Xiaoqing's body had been stored in a cold storage, it is very likely that it was cleaned after all the bodies were disposed of.

However, in an average hotel, the freezer will not be washed once from the time it is purchased until it is worn out or the restaurant closes down.

"158 freezers..."

"Have the remaining 17 freezers been inspected?"

Zhang Chaoyang nodded: "I've checked them all, too."

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

"I have verified it with the staff of the relevant hotel and there is no doubt about it."

Zhang Chaoyang's group has the most people.

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

Only then did we check out the hotels within three kilometers in two days.

However, it now seems that the possibility of hotel personnel committing the crime has been basically ruled out.

“What about the slaughterhouse and the cold-blooded investigation?”

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

"However, we have conducted inspections on the raw meat sales points at nearby farmers' markets."

"Still using three kilometers as the limit, we checked all raw meat sales outlets."

"There are 6 outlets in total."

"However, we have conducted a screening of all personnel in the outlets and frozen meat freezers."

"The results are the same as the hotel's screening results. There is no doubt about it."

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 investigated and samples from the cold storage have been checked."

"The cold chain transfer station is well managed and there are manifests of goods in and out, which eliminates suspicion."

"The cold storages of five large supermarkets all have managers, and they are only stored at low temperatures and cannot be refrigerated."

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

"They don't even have the function of freezing."

Zhang Chaoyang's investigation has been very detailed.

Three kilometers outside the school, basically all places where corpses could be frozen and disposed of could be surveyed.

Now, the remaining and most important location is to investigate.

Zhang Chaoyang has not reported yet.

And this is what Chen Yan is most concerned about.

"How is the investigation of the canteens and restaurants on campus?"
