The newly transferred member of the team, named Tan, is a top student in data analysis.

He is responsible for integrating the suspects, the case itself and parallel evidence in the relevant case into one place, and then analyzing the possible correlation points between several cases through the most accurate data, the suspect's coexistence habits in different cases, thereby analyzing some unknown recordable conditions of the suspect.

For example, what are your preferences, your behavior habits, your temper, and even what time do you like to commit a crime? What are the targets of the crime?...

And now, this mysterious big data analyst has given Ruan Rou a new discovery after he had just conducted these two cases and merged them into a composite case.

"Head! That man named Dongzi was on the construction site of the construction parking lot that year."

"And the developer of that parking lot is put aside for the time being, and the contractor of that parking lot has been finally confirmed."

"It was contracted by a contractor from Hebei."

"And this man named Dongzi came from the same village as the founder himself."

"After completing this construction project, the contractor undertook the construction project of a supermarket building in Sanli, Jiayuan, Fengtai District."

"Because of the two fellow villagers, the record at that time was that Dongzi himself and the contractor went to the new construction site together."

Ruan Rou was very surprised to hear this. Is there anything wrong with this?

If you have an investigation into Dongzi’s current traces, the easiest thing to find is the address he transferred for the first time.

The personnel in charge of the investigation have already found that Dongzi had once again traveled to two small construction sites after the project from Sanli of Jiayuan was completed.

Comrade Tan Chengming brought up this old consultation and what did he do?

So Ruan Rou didn't say anything, but Tan Chengming, who was chattering over there, kept talking nonstop: "And guess what I found?"

"When the project in Jiayuan Sanli was about to end, near the construction site, near a dead corner near the gate of a community, a high school girl who had been home from night study was knocked out and dragged to the temporary garbage dump of construction waste at the construction site and violated it."

"That night, after my family found out that the girl had not returned home, in addition to spontaneous search, they also reported the case to the police station where Sanli of Jiayuan was located."

"The police records from the local police station and the sealed archives of this unsolved case are now in the old case records of our Old Case Investigation Section in 2006."

"After I came to our Old Case Investigation Office, I did nothing else. I just sorted out all the backlog of old cases assigned to our department in the Archives Office and recorded them in different categories in my big data chronology."

"Through my comparison of Dongzi's line, I found out that he had a connection with this case."
