Chapter 130

Su Mian opens the door and sees that Han Chen has already got up and is sitting in the sofa with a coat on her body and her laptop on her lap.

"Why don't you sleep more?" She asked, sitting next to him.

He picked up his teacup and took a sip. The tea was still brought from his home. It was fragrant.

"Had a good chat?" A salty voice.

Su Mian: Poof. " This vinegar jar. He put his hand around his neck and kissed him hard for a while, which was flattering. His face is always light. Obviously, the young master has broken his temper again. Su Mian still needs to work hard.

Su Mian is a smart person. He stares at the computer screen and changes the topic: "are you watching that video?" The picture is fixed in the scene of L bending down to pay homage. In the dark alley, there is only the crescent moon in the narrow sky, and a wisp of light that is cast down from nowhere.

"Well." He said, after all, he put his arm around her waist and looked at the screen together, "what did you find before?"

Su Mian shook his head: "what can we find? There is nothing in the picture. These alleys are all over the street. Of course, the three of them will not leave clues. "

Han Shen not to say yes or no, loosened her body slightly leaning forward, fingers also adjusted the picture before and after, very focused. The man who works hard is the most handsome. Su Mian leans on his arms and looks up at his side face: "don't tell me that you really have a discovery."

He looked down at her, his eyes were pale: "what if there is? In the future, you will be obedient? "

Where is this? Still jealous?

But Su Mian has been planted in his hands several times. Can he not learn to be smart? "You said that, I've always been very considerate? Almost become your Zhou Xiaozhuan, omnipotent Small Follower! Tell me, tell me, what have you found? "

Clearly such a beautiful woman, play Lai Lai, always make you speechless. Han Chen looks at her, smiles, turns his head and continues to stare at the screen, but his hand slips onto her waist again and hugs her.

"In the picture, there are three clues." He said.

"Ah?" For the first time, Su Mian felt that her IQ was not enough. Three more?

Han Shen's fingers gently touched three times on the screen: "moon, light and sound."

"The moon..." Su Mian looked at the crescent moon in the picture, and suddenly realized, "is it based on the radian of the moon to speculate on which day of this month?"

Han Shen was staring at the screen, his eyes closed slightly, and his expression showed a little rebellious Indifference: "what's the use of that? According to the height and radian of the moon in the sky, we can infer the time of the day

Su Mian opened his eyes, and finally raised his hand to hit a beautiful ring finger: "yes Although Han Chen only said one thing, once she opened her mind, she was slightly excited. Han Shen's eyes are so poisonous that he draws such an accurate conclusion.

At this time, Han Chen picked up her colorful soft leather notebook from the tea table in front of her. Su Mian noticed that the page he opened was full of beautiful and powerful handwriting, full of numbers and formulas, and even drew a simple sketch of trigonometric functions.

Well, I don't understand.

"It was the day before yesterday, between 3:00 and 3:30 in the middle of the night." He said.

"Eun!" Su Mian was so admirable that she looked at the way he pinched his pen between his fingers. She would bet that if Han Chen didn't work as a criminal police officer, he would be a surprisingly handsome cold faced mathematics professor.

"And then?" She asked.

A faint smile flashed in his eyes: "then the lamp. The rest of the alley is dark, except for the light in the picture. At three o'clock in the middle of the night, there are very few places where the lights will be on. " His fingers slide on the computer, enlarge the picture, and the light on the ground will also be enlarged.

He continued: "from the length of the clown's shadow and his height, you can calculate the distance and height between the lamp and him. The calculated distance is 20 meters and the height of the lamp is 15 meters. The lamp is all white, with uniform luster, no pattern and no projection of the outline of other decorations. Therefore, it is not a lamp in a household, but a street lamp in an open space. "

Su Mian was stunned. He said, "I checked. Last year, the city's streetlights were renovated in a unified way. The height is only two specifications: 8 meters and 12 meters, not 15 meters. In addition to lamp posts, street lamps will be installed in a place - under the eaves of buildings adjacent to the road, to illuminate passers-by. That is to say, 20 meters away from the clown's standing place, there is a five story building, installed with a white light, bright all night. "

"Lying trough!" Su Mian blurted out, crazy, crazy! He was asked to reason out the salient features of the site, the length and luster of the shadow were even, so whether it was street lamps or lighting street lamps installed in the high places of buildings - such details were found out by him, and the logic was impeccable.

According to this condition, the criminal police do not have to search for a needle in a haystack any more. They can quickly find out the location. What will be found out after finding out? Who knows, maybe it's close to their nest, or at least some of their whereabouts can be found. ——After all, Han Chen said that criminals only commit crimes in a place where they feel comfortable. They must feel that the place is very safe when they send this video.But now, they must have never thought that it was this video that seemed absolutely safe and powerful that made Han Shen find such an important clue!

She opened her arms and put her arm around Han Shen's thin waist: "how can you do that! You are a wonderful flower

Her words Han Chen slightly frowned, but the admiration of her eyebrows and eyes was naked. This makes Han Chen smile, as if there is a soft and comfortable breath around his chest. He leaned back, put his arms around her and knocked on the table top: "as for the sound, we need to go to the forensic science department to analyze it carefully. But there are two sounds with high resolution. One is the laughter of a and r. Using the instrument to analyze the voice print carefully, we can calculate the distance from their laughter to the wall on this side, and then infer the specific shape of the space they stand on; the second is the sound of traffic on the road, so we can try to calculate the distance from the road to the place where they stand. In this way, the brothers can find this place more accurately. "

According to voiceprint analysis, Su Mian only heard about it. But also can understand: the sound ripple, the speed, meets something to rebound, so as to determine the shape of the obstacle. I didn't expect Han chenlian to understand this. With these three clues, I'm afraid we can't find their meeting place?

-

at noon the next day, good news finally came and made a major breakthrough!

According to Han Shen's reasoning conclusion, after several hours of unremitting efforts, the criminal police actually found the place accurately. A wide range of searches then unfolded. In addition, Zhou Xiaozhuan successfully found a suspected car after mobilizing all the surveillance videos from 3:00 to 3:30 the night before yesterday.

The surveillance screen is 3:40-3:41, and the location is on the side of the road about 300 meters away from the lane. The surveillance was captured by a surveillance camera outside the bank on the road.

At that time, there was no one on this remote road.

Then three men came out of the alley. One of them, dressed in a clown's costume, is exactly L. Because of the dark light, they still can't see their faces clearly. And they keep their heads down.

L got into the driver's seat. A and R are in the back seat. The whole process is fast and silent. It was a common black car in this city. Soon, the car started and disappeared. The surveillance camera clearly captured the license plate number: "ka7xxxx52".

"Criminals are likely to use fake license plates, but they are not aware that the car has been photographed, so they are likely to continue to use it." Han chenlengsheng ordered, "search this car in the whole city immediately."
