Qin Tao, business partner, friend!
Lu Chuan murmured to himself.
Lu Chuan has studied the files on Zhang Cuiying’s disappearance case in detail.
Because Zhang Cuiying is 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 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 arriving at the chemical plant, Zhang Cuiying would leave at noon and go to dinner with Qin Tao, who was 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.
After that, Zhang Cuiying drank afternoon tea until she got off work.
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. This situation probably repeats 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 opinion, 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 his 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 you 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 long time, 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? Help me mark them."
"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. The corresponding materials were delivered to Lu Chuan in less than 10 minutes. in hand.
Three people are sitting here, discussing while looking at the materials.
Zhao Kui personally conducted the investigation of these people, so he has 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 is at noon when the two of them are eating, and the other is when Zhang Cuiying drinks afternoon tea in the afternoon.
“The frequency of Qin Tao’s calls to Zhang Cuiying did not change before Zhang Cuiying’s disappearance.”
“This is very important, as 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 per 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.”
Both Zhang Hui and Zhao Kui nodded in agreement.
The vast majority of calls last about one minute.
The call records between Qin Tao and Zhang Cuiying are maintained at twice a day, each time lasting between more than 5 to 6 minutes. This shows that when the two talk on the phone, they are not just talking about someone. some things.
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 talk time?
Lu Chuan thinks it is highly unlikely.
Otherwise, Qin Tao would be really terrible.
As for the frequency of Zhang Cuiying’s business partners calling him, 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 phone 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 business between the two people, involving millions of funds."
" 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 killed people with tricycles...
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 one minute, was made by the owner of a local chemical factory in Tang County."
"We also conducted a detailed investigation on this person. His chemical factory and Zhang Cuiying The chemical factory there has a deep cooperative relationship."
"The products produced by the chemical factory there are the raw materials of Zhang Cuiying Chemical Factory."
"The two of them have been cooperating for more than 5 years. "
"There are many economic transactions 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 the other party's accounts." "
"In addition, we investigated the other party's actions during the time when Zhang Cuiying disappeared, and there is evidence that the other party had no time to commit the crime."
There was no motive and no time to commit the crime. Of course the suspicion can be ruled out.
Qin Tao's suspicions aside, the suspicions of business partners have been basically eliminated. The only ones left 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 this chapter)
