Chương 2620: Chapter 2615-you got it right again

Tokyo safehouse.

Zhao Yu was holding a huge hamburger and chewing on it as he organized the case in his notebook.

Through the information provided by Li Zhen Zhu, he already knew that the case that the successor wanted him to investigate was not a simple unsolved case, but an international serial murder!

In the 1990s, the murderer had used similar methods to kill several young girls in different cities in different countries.

Who could this person be?

The first person that came to Zhao Yu's mind was the mysterious foreigner who had driven a luxury car and sent miss Xin Jia home.

However, after some thought, he felt that the foreigner was not the real murderer.

This was because a similar case happened in kyokyoto, Seoul, Korea, in July 1991, while the Tokyo sunflower case happened in August of the same year.

Previously, Xin Jia's sister from Ping Cheng had said that she had seen the foreigner send her sister home a month before the incident.
