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

Qin Tao, business partner, friend!

Lu Chuan murmured to himself.

Lu Chuan had studied the files on the Zhang Cuiying disappearance case in detail.

Because Zhang Cuiying was well-known in Tang County as an entrepreneur, the Tang County Public Security Bureau paid great attention to his disappearance.

Zhang Kui, deputy captain of the Criminal Police Brigade of the Tang County Public Security Bureau, personally took charge of the case.

On the day Zhang Cuiying disappeared, a complete review of her itinerary was conducted.

There was nothing unusual about Zhang Cuiying after she left home in the morning.

Normally, after Zhang Cuiying arrives at the chemical plant, she will leave at noon and go to eat with Qin Tao who is working out in the gym.

In the afternoon, Zhang Cuiying will return to the chemical plant again, but usually she will only stay in the chemical plant for less than two hours before leaving.

From then until get off work, Zhang Cuiying was drinking afternoon tea.

The places where she drinks afternoon tea are relatively fixed, and they are all famous coffee shops in Tang County.

And according to Qin Tao, Zhang Cuiying would invite some friends when drinking tea.

Zhang Cuiying's life is relatively regular. She probably repeats this situation every day. She will go home after having afternoon tea.

According to the information provided by Qin Tao, after the two got married, Zhang Cuiying went out to socialize very rarely.

On average, it's once a week.

The phone calls Zhang Cuiying received before she disappeared were from her business partner Qin Tao and several friends.

In Lu Chuan's view, if it was not a temporary kidnapping, then the person related to Zhang Cuiying's disappearance is likely to be among the people she has contacted recently.

The possibility of temporary kidnapping seems unlikely.

Because if it is a kidnapping, the other party will definitely contact the family to send money.

However, if they were kidnappers, Qin Tao and Zhang Cuiying never received any contact phone calls from their homes.

This is abnormal. After all, if Zhang Cuiying was really kidnapped and blackmailed, for the sake of her own life safety, she would not risk her life for money.

Even if they are eventually rejected, there will be a process of contacting family members to extort money.

This was also the final reason why Zhao Kui and others ruled out the suspicion of kidnapping and extortion at the first opportunity.

After thinking for a while, Lu Chuan looked at Zhao Kui.

"Team Zhao, show me the call records of the people who contacted Zhang Cuiying three days before he disappeared. What is the relationship between these people and Zhang Cuiying? Mark them for me."

"No problem, everything is ready-made. I'll have someone sort it out and deliver it to you right away."

What Zhao Kui said was indeed very fast, and the corresponding materials were delivered to Lu Chuan in less than 10 minutes.

The three of them sat here, looking at the materials and discussing.

Zhao Kui personally conducted the investigation on these people, so he had a better understanding of everyone's situation.

Lu Chuan and Zhang Hui asked questions, and Zhao Kui was responsible for answering them.

"Qin Tao called Zhang Cuiying with a relatively regular frequency."

Judging from the call records of three days, Qin Tao made about two calls to Zhang Cuiying every day.

One was at noon when the two of them were having dinner, and the other was in the afternoon when Zhang Cuiying was drinking tea.

"The frequency of Qin Tao's calls to Zhang Cuiying did not change before Zhang Cuiying disappeared."

"This is very important. It shows that there has been no major change in the relationship between the two."

Lu Chuan focused mainly on the frequency of phone calls. After all, if Qin Tao is really the murderer, then his psychology will definitely change slightly.

Psychological changes will most likely lead to changes in external behavior.

Lu Chuan pointed to the time of the call records within three days.

"We saw that Qin Tao called Zhang Cuiying. Not only did the frequency of calls every day remain unchanged, but the duration of each conversation was basically more than five minutes and less than six minutes."

5 to 6 minutes is actually quite a long time for making a phone call.

"If there was nothing particularly important or cumbersome, the conversation between the two would not have been so long."

Zhang Hui and Zhao Kui both nodded in approval.

The vast majority of calls actually last about a minute.

The call records between Qin Tao and Zhang Cuiying were kept at twice a day, each time lasting between more than 5 to 6 minutes, which shows that the two did not just talk about certain things when they talked.

The two of them probably have a better relationship and talk more about love.

And if Qin Tao is indeed the murderer, can he still deliberately maintain this frequency and call time?

Lu Chuan believed that it was highly unlikely.

Otherwise, Qin Tao would be really terrible.

As for the frequency of calls from Zhang Cuiying’s business partners, only two or three of them made two calls within three days, and no one made more than three calls.

One of the phone calls was particularly long, more than 30 minutes.

Most other phone calls last about 10 minutes.

Only one partner's call lasts for one minute.

"We investigated and understood Zhang Cuiying's partners one by one at that time."

Zhao Kui took the initiative to explain the situation to Lu Chuan and Zhang Hui.

"The longer call, this thirty-minute call, is from a business partner of Zhang Cuiying in another province. There is a big deal between the two of them, involving millions of dollars."

"We checked some contracts of Zhang Cuiying Chemical Factory and found this cooperation, so it should not be a big problem."

Lu Chuan nodded, people from other provinces came to commit crimes, and they used tricycles to kill people...

It's really unlikely.

"We have also investigated the situation of several other people. They are all partners of Zhang Cuiying Chemical Factory, some from our city and some from other cities."

"The shortest call, which lasted less than a minute, was made by the owner of a local chemical factory in Tang County."

"We have also conducted a detailed investigation on this person. His chemical factory has a deep cooperative relationship with Zhang Cuiying's chemical factory."

"The products produced by the chemical plant over there are the raw materials of Zhang Cuiying Chemical Plant."

"The two of them have been working together for more than five years."

"There's a lot of financial dealings between the two chemical plants."

"But judging from the results of our investigation, these economic transactions are relatively normal payments for goods in and out."

"Zhang Cuiying's chemical plant is in better operating conditions and has never defaulted on its accounts."

"In addition, we investigated the other party's actions during the time when Zhang Cuiying disappeared, and there is evidence to prove that the other party did not have time to commit the crime."

There is no motive and no time of crime, so the suspicion can certainly be ruled out.

Qin Tao's suspicions aside, the suspicions of her business partners have been basically eliminated, and the only ones who have contact with Zhang Cuiying are some of her friends.

In three days, Zhang Cuiying received a total of five calls from her friends. (End of chapter)
