Han Cheng felt that no matter whether the mysterious man was walking on a national highway or a country road, it was impossible to avoid all the surveillance cameras.
For example, when leaving a city or entering a city, the traffic department generally installs sky-eye monitoring at some important intersections.
Han Cheng felt that there should be scenes of mysterious men coming and going at these intersections.
So Han Cheng asked the transportation department to retrieve surveillance videos at important intersections from Rui City to Nan City. The date range of the surveillance videos retrieved was from the day Ren Li was murdered to the day Fang Yang was murdered.
After Han Cheng used the double-speed viewing skill to watch all the surveillance videos.
More than a hundred vehicles were ultimately screened out.
People from the Second Criminal Investigation Team led a group of ordinary police officers to investigate and verify each car one by one, and finally locked in a jeep with a fake license plate.
Because it was a decked-out black car.
Obviously, trying to find the mysterious man by using a car will not work!
However, since this car has entered Nanshi, it will definitely leave some traces.
So Han Cheng asked Nan City's transportation department to pull out the surveillance videos of all important intersections in the city.
Finally, the mysterious man's movements after entering Nanshi were discovered.
After the mysterious man drove a jeep into Nanshi, he came to the neighborhood where Zuo Jun lived and drove around several times.
Through the surveillance video, Han Cheng saw the mysterious man wearing a mask and gold-rimmed glasses, which matched the description of the mysterious man by the wretched man who lived next door to Ren Li.
At the same time, he also saw a vaguely tied person lying in the back seat of the jeep driven by the mysterious man. The person seemed to be able to move.
Han Cheng guessed that the kidnapped person should be Fang Yang.
According to calculations from Fang Yang’s time of death, Fang Yang was still alive at that time.
In the surveillance video, the mysterious man drove a jeep around the neighborhood where Zuo Jun lived for several times, without stopping for a long time, and soon drove towards the suburbs.
The direction of the vehicle was exactly where Han Cheng and the others found Fang Yang's body.
Here comes the problem!
Why is the mysterious man hanging around where Zuo Jun lives?
Could it be that the target of the mysterious man is not Fang Yang but Zuo Jun?
Then why did he choose to kill Fang Yang instead of going to Zuo Jun?
The previous mysteries have not yet been solved, and now a new one has been added.
No matter what, finding this mysterious man is still the key to the case.
Han Cheng once again checked the surveillance videos of important intersections out of the city in Nan City after Fang Yang was killed, and finally found the video of the mysterious man leaving the city.
This time the mysterious man did not take the country road, but directly took the national highway.
Although there are fewer surveillances on national highways than on highways, there are surveillances every other distance. It is not difficult to find out the whereabouts of the mysterious man.
So, Han Cheng called up the surveillance video along the direction of the mysterious man's walking, and finally found out that the mysterious man's destination was Kunming City.
This is strange.
The mysterious man wandered around Rui City and finally returned to Kun City where Fang Yang's family was located.
The mysterious man's amazing operation really confused Han Cheng and the others!
What does the mysterious man want to do in Kunming?
Want to blackmail Fang Yang's parents again?
But according to Fang Yang's parents, they have never received any blackmail calls from beginning to end.
If the mysterious man didn't come to Kunshi to blackmail Fang Yang's parents.
Could it be that he was planning to sit there and wait for death?
Obviously not!
If you want to solve all the mysteries, you must first find this mysterious man.
Now we know that he is hiding somewhere in Kunming City. As long as we find that dazzling jeep, we may be able to find him.
In order to find the jeep, Kunming police mobilized police forces from across the city to conduct a secret search.
This was specially ordered by Han Cheng, because Han Cheng felt that if they searched the jeep with great fanfare, they might be able to clear up the alarm.
Once the mysterious man escapes again, they will have to trace his whereabouts again.
Thanks to the efforts of the Kunming police, they finally found the jeep abandoned by the mysterious man in a deserted place on the outskirts of the city.
After a detailed inspection of the Jeep by the Kunming Police Department’s trace inspection personnel.
They found human hair from the trunk of the car. After examining the hair, they confirmed that it belonged to Fang Yang.
This shows that after Fang Yang was kidnapped, he was hidden in the trunk of the car.
In the cab of the car, they extracted a fingerprint.
The Kunming police put the fingerprint into the police fingerprint database for comparison.
As a result, one person was identified.
This person's name is Zeng Hao, male, 27 years old, foreign Chinese.
Why did a foreign Chinese come all the way to Longguo to plan such a murder?
Han Cheng felt that there must be some ulterior conspiracy here.
In order to learn more about Zeng Hao, Han Cheng contacted the police of country F where Zeng Hao was located through diplomatic channels.
Through the police in country F, Han Cheng learned that Zeng Hao was born in country F. His mother's name was Zeng Rou, who was a native of Long Country. She immigrated to country F 27 years ago and died of a serious illness six months ago.
The information about Zeng Hao's father is ominous.
Based on Zeng Hao's age, Han Cheng speculated that Zeng Rou should have been pregnant before immigrating.
Therefore, Zeng Hao's biological father is most likely from the Dragon Kingdom.
So, will Zeng Hao look for his biological father when he returns this time?
In order to understand who is most likely to be Zeng Hao's biological father, Han Cheng investigated Zeng Rou's life trajectory before immigrating.
As a result, a shocking coincidence was discovered.
