Solved: The Detective Returns

Seeing this, Lin Can and Ma Guozhen couldn't help but light up.

This man is indeed somewhat similar to the murderer in terms of body shape and dress!

However, the monitoring equipment in the building is relatively old, and the clarity is not high, so the picture looks a little blurry.

Lin Can paused the video, and then enlarged the picture slightly, and the figure part appeared more mosaic-quality.

The black figure in the picture has his hands in his pockets, his head slightly bowed, and his eyes are completely obscured by the cap.

Lin Can squinted his eyes and observed for a while, then slowly moved the mouse to the collar of the black shadow, and a shiny reflection came into view.

"What is this?".

Ma Guozhen also noticed where the mouse was pointing, he frowned and thought, but the picture was too blurry, and it was not easy for him to make an accurate judgment for a while.

"Studs. "

Lin Can said slowly.

Ma Guozhen suddenly brightened, Lin Can's words woke him up, although the picture on the screen did not change, but when he looked at the screen again, the shining place seemed to become clear.

That's clearly an earring!

It's just that the figure is slightly hunched in the neck, and its ears are right next to the collar.

What a precise and keen observation!

Ma Guozhen looked at Lin Can on the side, secretly admired in his heart, and at the same time couldn't help but feel a little emotional.

Although his age is not very old, compared with Lin Can, Ma Guozhen suddenly has a feeling that he is old.

It seems that he is indeed a little old, in addition to the fact that his criminal investigation analysis ability is not comparable to Lin Can, and even his eyesight is so much worse than ......

Lin Can restarted the video, and the man in the leather coat walked straight into the building through the main entrance.

Immediately after that, the picture suddenly accelerated at a speed of more than 100 times, and soon the time in the upper right corner came to half past eleven last night.

The footage in the surveillance is a little dark, only the lights at the door illuminate the surroundings.

The leather-clad man who entered in the morning reappeared in the surveillance footage, he seemed to be carrying something in his hand, but he blocked it with his clothes, his expression seemed to become a little nervous, and his steps were a little hurried.

Lin Can looked at the video in front of him intently, and then at the moment when the leather-clad man was about to leave the monitoring area, Lin Can pressed the pause button.

He partially enlarged the things that the leather-clad man was carrying, and through the cover of the clothes, he could still see some silver reflections in the gaps.

Later, Ma Guozhen was asked to open the video uploaded by the murderer on the Internet, and adjusted it to the toolbox screen to pause.

After a period of comparison, Lin Can slowly spoke: "What this leather-clad man is carrying in his hand is the toolbox used by the murderer. "

"Entering the building at ten o'clock in the morning and leaving at half past eleven in the evening, entering and exiting the time coincided with the time of the murder, and all the details and characteristics were consistent, it seems that he is the murderer. "

Ma Guozhen's expression became more and more excited, "And the height and body shape can be completely correct...... It's just that I still can't see his face and can't tell his exact identity. "

Lin Can silently looked at the picture on the screen, as if thinking about something.

"At the moment, we can only use the clumsiest methods. "

Ma Guozhen said: "After a while, I will ask the police to check the road surveillance near the building all the way to see if I can determine the whereabouts of the murderer, maybe I will find something." "

Lin Can nodded, and then continued to press the play button, and after the leather-clad man carried the box out of the monitoring range, the video ended completely.

"In addition to the monitoring at the main entrance, what about the monitoring in the elevator or the corridor?"

Lin Can asked Ma Guozhen on the side, "Isn't there a murderer found here?"

The investigating police officer said that it happened to be overhauled that day, and the monitoring of the elevator and the corridor was lost for a long time. "

Ma Guozhen replied: "In the surveillance in other time periods, no murderer's activities were found. "

"Anyway, they sent all the surveillance data in the building yesterday, and they are all in this folder. "

Ma Guozhen pointed to the pile of surveillance video data on the computer and said: "We can quickly go through these surveillance materials together in a while to avoid any omissions from them." "

"Okay, let's do it first. "

Lin Can thought for a moment, and then said to Ma Guozhen: "You ask the police officer to bring another laptop." "

"Take the computer?".

Ma Guozhen picked up a cup of teacup on the table, took a sip, and said: "The performance of the computer in my office is enough, and it is no problem to watch a monitor." "

"That's not what I meant. "

Lin Can said: "I may be able to watch the speed of monitoring...... So it's better to look at it separately. "

Hearing this, Ma Guozhen almost squirted out the tea in his mouth.

Feelings: Professor Lin is worried that he can't keep up with his viewing speed......

I have been working in the police station for more than ten years, and I have a lot of experience in handling cases, and watching this kind of surveillance video is even more commonplace.

Although Ma Guozhen is not a specialized technician, he can still watch surveillance at four times the speed, or even eight times the speed!

But since Lin Can asked for this, Ma Guozhen couldn't refuse.

He nodded, then took out his phone and dialed his officer.

Later, Ma Guozhen sent him all the surveillance video files according to Lin Can's request.

A few minutes later, a police officer pushed open the office door and walked into the office, also carrying a briefcase containing a laptop.

After placing the computer on the table in front of Lin Can and connecting the corresponding power cord, the police officer left the office directly.

Lin Can turned on the computer, logged in to his mailbox, and downloaded the file sent by Ma Guozhen, and then he opened the corresponding video file and directly adjusted the speed to play it.

Ma Guozhen, who was on the side, glanced at Lin Can's computer screen and almost lost his eyes.

He shifted his gaze to the double-speed marker in the lower right corner, and a bright 32X almost blinded him.

Thirty-two times faster!
