    "What? Cat's eye unlocking?" Except for me, none of them here know much about this unlocking method.

    "Look, this cat's eye has obviously been tampered with!" As I said that, I shook it hard twice with my hand, and the cat's eye that was still inserted in the door was easily pulled out by me: "Obviously, the cat's eye  It's been removed before."

    "Um!"

    "And look at the tape marks on the door." Everyone followed my fingertips and looked at the black rectangular spots on the door.

    "We can see from the posting traces that the original position of the New Year painting should be slightly below the cat's eye, and it did not block the cat's eye. The suspect may have been in a hurry during the crime and did not have time to reinstall the cat's eye, but  He was also afraid that we would see through his method of opening the door, so he tore off the New Year picture and blocked the cat's eye, but accidentally pasted the New Year picture right, exposing the flaw."

    "But how did the suspect open the lock through the peephole?" Ye Qian has always been impatient.

    I put the strong light on the cat¡¯s eye again: ¡°Have you noticed that there are many ¡®concave¡¯-shaped indentations on the cat¡¯s eye?¡±

    "Yes, there are quite a few!"

    "This is the trace left by using professional cat eye pliers to twist the cat eye. First unscrew the cat eye, then use a special 'L' shaped tool to go deep into the hole, and use the other end of the tool to hold the handle on the inside of the door  , as long as you press down with a little force, the door can be opened."

    "Is the suspect still a professional locksmith?" Ye Qian's eyes widened.

    "Even if he's not a locksmith, he knows the business very well."

    "Xiaolong, how are these 'L'-shaped tools made?" Pang Lei's eyebrows knitted together.

    "The length of the tool should be determined according to the position of the door lock, and it should be easy to carry, so generally such a tool is assembled, and it can be made by screwing a few small iron bars together with screw heads in the middle."

    "Can you be sure of your judgment?"

    ¡°Brother Lei, let me study it carefully!¡± When Fat Lei said this, I felt unsure.  Then I removed the entire cat's eye. The holes where the cat's eye was installed were two pieces of iron sheet. As long as something exerts force on it, the iron sheet would curl up in the hole.

    "There are traces of iron curls on both the inside and outside of the door, and they are in a straight line." Then I opened the door. "There are fresh indentations on the handle of the inner lock of the door. I can confirm that the suspect used the unlocking method  It¡¯s just a cat¡¯s eye lock.¡±

    "That is to say, our next focus is to identify people who can pick locks from the deceased's relationship circle?" Ye Qian stood aside and began to think about new clues to solve the case.

    "Xiaolong, there is something urgent that I need to confirm again. Let's hurry up and return to the unit." Fat Lei's expression was quite serious.

    The crime scene was sealed again, and we rushed back to the department almost non-stop.  I didn't even have time to put down the survey box in my hand before I was pulled into his office by Fat Lei.  In order to understand what was going on, others followed.

    As soon as Fat Lei entered the door, he pressed the power button on the computer chassis.  With a burst of boot music, a desktop unique to the XP system appears in front of us.  The desktop was densely packed with various files. Pang Lei moved the mouse and clicked on an avi video file called "The murder suspect in the green shade community enters the door" and began to introduce: "Based on Xiaolong's analysis, and Lao Xian.  The suspect was found through the photo of the suspect's clothing provided. This is an image of the suspect entering the door captured by the camera at the east gate of the community. We can clearly observe from the picture that the suspect did not hold anything in his hands when entering the community.  "

    After Fat Lei finished speaking, he clicked on another video: "This is a video of the suspect leaving the community after committing the crime. His hands were empty and there was nothing. According to Xiaolong's analysis, the suspect used professional cat-eye pliers and assembled locks.  Tools, how do you explain this?¡±

    "Does the suspect have an insider in the community?" My face became very ugly, and I raised this hypothesis without any confidence.

    When we had a heated discussion about why this happened, Brother Ming stared at the screen and said nothing. Until the sound of our discussion gradually disappeared, his eyes never moved away from the screen.

    I thought he was in a daze, so I tentatively shouted: "Brother Ming?"

    "Jiao Lei, is there any surveillance on the elevator?" When Brother Ming asked this question, his expression became much more relaxed. He probably made some important discovery.

    ¡°The suspect deliberately avoided the surveillance of the elevator when committing the crime.?It's the stairs.  "

    "Yes, I found the suspect's footprints in the stairwell as he went up and down the stairs." I added.

    ¡°I have conducted a detailed inspection of all the stairs in the entire building from the first floor to the top, and found no biological evidence such as saliva spots or snot spots.¡± Lao Xian also made a concluding speech.

    We all thought Brother Ming was reminding us that we had neglected the investigation of the peripheral site, but in fact we found nothing at the peripheral site.

    "I followed you when you were surveying the corridor. That's not what I meant."

    "That's not what you meant?" I was already a little confused.

    "Jiao Lei, is this the only surveillance video that records the suspect alone?" Brother Ming did not answer my question, but continued to "torture" Fat Lei.

    "These are the two clearest videos."

    ¡°Okay, choose a reference point and use the cutout tool to cut out the suspect¡¯s photos from these two videos.¡±

    "Then I will take two pictures using the gate as a reference point."

    "Okay, as soon as possible!" Brother Ming gave up his seat to Fat Lei.

    Snap, snap!  The clicks of mice and the typing of keyboards can be heard in the office.

    "That's it!" Soon, Pang Lei placed the two photos in a folder.

    "Scale according to the same proportion!"

    "good!"

    "Have you noticed any problems?" Ming Ge's index finger and middle finger pointed at the suspect's abdomen in the two photos respectively.

    Ye Qian¡¯s eyes were almost glued to the computer screen: ¡°The photo when I walked in seemed a little fatter!¡±

    "Yes, when I watched the two videos, I found that the suspect's entire body posture changed when he entered and exited the door!"

    Ming Ge¡¯s forensic skills can be ranked among the top ten in the entire Bayan Province. Pang Lei once joked that Ming Ge can analyze the cause of death just by looking at the surface characteristics of corpses.  After these years of practice, I found that there is no water in what Fat Lei said. Observing the subtle differences in a person's physical characteristics is extremely simple for Brother Ming.

    "You can barely see it after magnifying it so much. Brother Ming's eyes are not ordinary poisonous!" Fat Lei was so impressed that he fell to the ground.

    Brother Ming had no time to joke and said with a serious expression: "When the suspect entered the community, his abdomen was a little bulging, and when he left the community, the entire abdomen became much flatter. So I suspect that the suspect opened the door before committing the crime.  The tools were stuffed inside his leather jacket, and after the killing, he threw them in the community."

    "Did you just throw it in the trash can?"

    "This possibility cannot be ruled out."

    "Ye Qian."

    "Here, Director Leng."

    "Contact the property management of the community and check all the staff responsible for taking out the garbage that day. Be sure to determine the whereabouts of the crime tools."

    "clear."

    "Guoxian, if you can find the unlocking tools, can you extract relevant biological samples?" Ming Ge asked with some uncertainty.

    Lao Xian raised his lips: "Xiaolong just said that this tool needs to be assembled to be completed. If the suspect assembles it with bare hands, tissue cells will fall off, and I should be able to extract some biological samples from the screw knob!"

    "Okay!" Brother Ming gave a thumbs up.  (Remember the website address: www.hlnovel.com
