Trafficking cases have always been characterized by high secrets, family crimes, difficult to confirm evidence, and long time span.

This time, Chen Yan followed the clues and found so many clues.

The rescue team was formed immediately, but many of them were in other provinces, so Qinchuan needed to communicate one by one.

Chen Yan focused his main energy on pursuing Sister Sun.

In less than an hour, Liu Qingshan's investigation results came out.

There are seven mobile phone numbers that Song Wenlong has used in recent years.

One of the mobile phone numbers has been used 20 years ago to the present.

And this number is the exclusive number to contact the other party.

"This Song Wenlong began to record the other party's phone number ten years ago, although the other party would change a new phone number every time."

"However, we mainly identified three locations through the base station we linked to by the other party's phone."

"Three positions?"

Chen Yan was slightly stunned.

If there are only three positions, it means that the other party basically did not move when directing Song Wenlong.

"Yes, there are three positions." Liu Qingshan handed a report.

"The first location is the urban village we just visited."

Um?

"Has the other party lived in this Songjia Village over the years?"

Chen Yan took the report and watched it carefully.

Base Station No. 3 of Songjia Village.

Base station No. 2, Pingyuan Road.

Baotashan No. 1 Base Station!

These are the three base stations that the other party has made a phone call.

Among them, the number of calls made at base station No. 3 of Songjia Village is not less than half of the total number of all calls.
Chapter completed!
