Qin Tao, business partner, friend!
Lu Chuan muttered to himself.
Lu Chuan had meticulously studied the case file of Zhang Cuiying’s disappearance.
Because of Zhang Cuiying’s reputation as an entrepreneur in Tang County, her disappearance received significant attention from the Tang County Public Security Bureau.
Deputy Captain of the Tang County Public Security Bureau Criminal Investigation Team, Zhang Kui, personally oversaw the investigation of this case.
On the day Zhang Cuiying disappeared, a complete review of her itinerary was conducted.
There were no abnormalities when Zhang Cuiying left home in the morning.
Normally, after arriving at the chemical plant, Zhang Cuiying would leave at noon and have lunch with Qin Tao, who was working out at the gym.
In the afternoon, Zhang Cuiying would return to the chemical plant, but usually, she would leave after staying there for less than two hours.
During the time before the end of the workday, Zhang Cuiying would be having afternoon tea.
The places she had afternoon tea were relatively consistent, mostly a few well-known cafes in Tang County.
Also, according to Qin Tao, Zhang Cuiying often invited some friends for tea.
Zhang Cuiying’s life was quite routine, typically repeating the same pattern every day, returning home after afternoon tea.
According to the information provided by Qin Tao, after getting married, Zhang Cuiying rarely went out for social engagements.
On average, about once a week.
Before Zhang Cuiying’s disappearance, the calls she received were mostly from business partners and Qin Tao, as well as a few friends.
In Lu Chuan’s view, if it wasn’t a spontaneous kidnapping, then those involved in Zhang Cuiying’s disappearance were likely among the people she had recently been in contact with.
The possibility of a spontaneous kidnapping seemed unlikely.
Because if it were a kidnapping, the perpetrator would definitely contact the family for ransom. fɾeeweɓnѳveɭ.com
However, neither Qin Tao nor Zhang Cuiying’s family ever received any such contact.
This was unusual, as if Zhang Cuiying had truly been kidnapped for ransom, for her own life safety, she wouldn’t risk her life for money.
Even if they were ultimately planning to kill her, there would be a process of contacting the family for ransom money.
This was the ultimate reason why Zhang Kui and others immediately ruled out the suspicion of kidnapping and ransom.
After pondering for a while, Lu Chuan looked at Zhang Kui.
"Captain Zhao, show me the phone records of the people who contacted Zhang Cuiying in the three days before her disappearance. What were their relationships with her? Please mark them for me."
"No problem, everything is ready. I’ll have someone organize it and send it over right away."
Zhao Kui was true to his word; within less than ten minutes, the corresponding materials were handed over to Lu Chuan.
The three of them sat there, reviewing the materials while discussing.
Zhao Kui had personally investigated these people, so he was familiar with each of their situations.
Lu Chuan and Zhang Hui asked questions, and Zhao Kui answered them.
"Qin Tao called Zhang Cuiying with a relatively regular frequency."
From the three days of phone records, Qin Tao called Zhang Cuiying about twice a day.
One call during their lunch time, another during Zhang Cuiying’s afternoon tea time.
"The calling frequency of Qin Tao to Zhang Cuiying didn’t change before her disappearance."
"This is important because it indicates no significant changes in their relationship."
Lu Chuan focused mainly on the call frequency.
Because if Qin Tao were the perpetrator, there would likely be subtle changes in his psychology.
Psychological changes would most likely lead to changes in external behavior.
Lu Chuan pointed to the timestamps on the phone records within three days.
"Looking at Qin Tao’s calls to Zhang Cuiying, not only did the daily frequency remain unchanged, but the duration of each call was basically between five to six minutes."
to 6 minutes is quite a long duration for a phone call.
"If nothing particularly important or complex was being discussed, their conversations wouldn’t last so long."
Zhang Hui and Zhao Kui nodded in agreement on this point.
The vast majority of calls typically lasted around a minute.
Yet, the call records between Qin Tao and Zhang Cuiying were maintained at twice daily, with durations between 5 to 6 minutes each, indicating that their discussions weren’t limited to specific issues.
The two were likely on good terms, engaging in personal talking.
If Qin Tao were the perpetrator, could he still deliberately maintain this call frequency and duration?
Lu Chuan deemed it highly unlikely.
Otherwise, Qin Tao must be truly terrifying.
As for the call frequency of business partners to Zhang Cuiying, only two or three people called twice within three days, and no one called more than three times.
One of these calls was particularly long, exceeding 30 minutes.
Many other calls lasted about 10 minutes.
Only one partner’s call lasted less than a minute.
"At the time, we conducted an investigation into these business partners of Zhang Cuiying one by one."
Zhao Kui voluntarily explained the situation to Lu Chuan and Zhang Hui.
"The call that lasted for over thirty minutes was with a business partner from another province involving a large transaction between them with millions in funds."
"We reviewed some of the contracts from Zhang Cuiying’s chemical plant and found this transaction, so it should not be of significant concern."
Lu Chuan nodded; coming from another province to commit a crime, pulling off such a murder...
The possibility seems indeed low.
"We also investigated the circumstances of the other individuals, all are some business partners of Zhang Cuiying’s chemical plant, some are local, and some are from out of town."
"The call with the shortest duration, less than a minute, was from the boss of a local chemical plant in Tang County."
"We also conducted a detailed investigation into this person, whose chemical plant has a deep cooperative relationship with Zhang Cuiying’s chemical plant."
"The products produced by that chemical plant are raw materials for Zhang Cuiying’s chemical plant."
"The business partnership between the two factories has lasted for over 5 years."
"There are many economic exchanges between the two chemical plants."
"But from our investigation results, these economic exchanges appear to be regular payment dealings for goods shipped."
"Additionally, Zhang Cuiying’s chemical plant has always been well-run and never delayed in paying the other party’s dues."
"Moreover, during Zhang Cuiying’s disappearance, we scrutinized the actions on the other party’s side, finding evidence proving they had no time to commit a crime."
No motive, no time to commit a crime; they can certainly be ruled out as suspects.
Leaving Qin Tao’s suspicion aside for now, the business partners’ suspicions are largely ruled out, remaining are some of her friends that Zhang Cuiying contacted.
Within those three days, Zhang Cuiying received a total of five calls from her friends.
