Chapter 20 (1/2)

Originally, through an afternoon's investigation, Zhang Jingfeng and Liang Huan have found out why BMW can't see the driver.

After repeated investigation by the assurance department, the inspectors found a trace of glue pasted on the windshield of BMW.

After inspection, it has been confirmed that the glue mark is left by some kind of glass film. The professional staff of the assurance department suspected that the murderer might have tampered with the windshield on the day of the crime. He may have used some kind of single light film. After pasting it, he can only see the outside from the inside, but can't see the inside from the outside.

Although some expensive car films can achieve similar effects, they can never be as opaque as the BMW of the day, and even the outline of a driver can not be captured.

Therefore, the killer must have used some special film. Finally, through the continuous efforts of colleagues in the assurance department, the brand of this film was finally found out.

Unexpectedly, this single light film is actually used by magicians to perform magic. When they perform large-scale magic, it is used to enhance the illusion effect.

This material is very special. At present, it is not produced in China and can only be imported from abroad.

”Let me say...” Liang Huan saw that there were not many people in the room. He actually lit a cigarette, bowed his head and took two mouthfuls. ”It's almost time to end this hand cutting case! The elder told us that the more the murderer wants to make the case perfect, the more evidence he will leave! This is certainly no exception. ”

”Why?” Zhao Yu is curious.

”The material of the film is so special. Check the source records. No matter online shopping or direct sales, you can find the target immediately!” Liang Huan also threw up a smoke ring, ”Xiao zhao'er, I see... Your full whiteboard is white!”

Oh

Zhao Yu pondered carefully. It seems that it is not so easy to be a perfect criminal. The more you consider, the more loopholes you will have. If the culprit of the hand chopping case is really pulled out by the glass film, this guy will certainly regret it very much.

In that case... Qu Ping, they must be paying close attention to this clue. well! I want to monitor them. Once the target appears, act immediately.

At this time, Zhang Jingfeng and Liang Huan cleaned up their desks, took some documents from the drawer, and then began to wear their coats and prepare to leave!

”What? What time is it? ” Zhao Yu looked at her watch. It was about an hour before she got off work.

”Cough!” Liang Huan grinned, ”if we hadn't come back, we'd have to reply to group leader qu. our brothers would have arrived home early!”

”Xiao Zhao,” Zhang Jingfeng patted Zhao Yu on the shoulder, ”don't be busy. No matter how much we do, the credit for solving the case is also from group leader Qu and their group B! Take a break! Let's go. Why don't we have a game of billiards with our brothers? ”

Zhao Yu looked at the two in front of her and felt a complex feeling in her heart. It seems that the police are different from the police. At least the two brothers are not as serious as other agents. No wonder the superior will transfer them to the long outstanding case team!

”Forget it, i... I have something else to do. Don't go. Go!” Zhao Yu is at a critical juncture. How can he play billiards with them?

”Well,” Zhang Jingfeng shook his head, ”let's play for a while! I'm afraid I don't have to play with the traffic team later. ”

Then they took their things and left.
