    After Brother Ming listened to my report, he immediately organized everyone in the department to go deep into the subsidence area to conduct a third survey.

    The subsidence lake where the suspect dumped his body is located in the northwest corner of the subsidence area. Walking about 500 meters north from there, you can directly reach an east-west national highway. This is also the shortest route for the suspect to escape the scene.  According to normal people's thinking, 99.9% of suspects will choose to leave via this road. But contrary to expectations, even with the most advanced footprint survey equipment, I did not find any suspicious traces on this road.

    The southeast corner is our entrance to and from the subsidence area, which we have surveyed countless times.

    The northeast corner is where the abandoned chemical plant is located. There used to be an entrance, but it has been blocked due to pollution problems.

    Three of the four entrances and exits are excluded, leaving only the last southwest corner.

    If I were a suspect, I would never choose the southwest as an escape exit. Why do you say that?  There are three reasons.  First, the entire subsidence area presents an irregular trapezoidal distribution. From northwest to southwest is the longest side of the trapezoid. The distance marked on the electronic map is 9.7 kilometers. Second, in the southwest of the subsidence area, except for a few sparse brick buildings,  , there are small uneven mounds everywhere in other places, and it is quite difficult to walk; thirdly, and most importantly, it is said that the southwest entrance is the first area where mines were excavated. The strata have long been hollowed out, and people can walk up  , it is easy to be dangerous.

    But surprisingly, the suspect¡¯s shoe prints left on a pile of dog poop turned ¡°impossible¡± into ¡°possible.¡±

    "Damn it, what is going on in this guy's head? Why does he never play his cards according to the routine?" I complained.

    Fat Lei said to the side: "If something goes wrong, there must be a monster. Xiaolong, I'm not afraid of your jokes. I'm really worried that something bad will happen."

    I raised my head and pointed at the surveillance probe hanging on the telephone pole: "The panoramic high-definition long-distance infrared camera has a storage period of two months. As long as the suspect passes by here, he will not be able to escape its eyes. My Brother Lei, do you think it is still possible?"  What could be wrong?"

    Fat Lei smacked his lips: "That's right. With Fatty's strength, as long as he dares to pass under surveillance, he will definitely not be able to escape my eyes."

    After struggling for a day, he finally got something to work with. Fat Lei transferred 12 investigators from the criminal police team to form a temporary video analysis team. The massive videos retrieved were cut into clips in 2-hour intervals and distributed to everyone.  The team members browse, and once suspicious situations are found, Fat Lei will conduct further analysis.

    The video is divided into four levels: "s, a, b, and c" with "time of the crime" as the midpoint. Level s is the video on the day of the crime, level a is the day before the crime, and level b is the day after the crime.  , level C is two days after the incident, and so on.

    "Teacher Jiao Lei, there is nothing wrong with one group."

    "There is no abnormality in the second group."

    "Everything is normal in the three groups."

    ""

    Two hours passed quickly, and 12 groups reported their video viewing status, and what Fat Lei handed over to them was the most important S-level video on the day of the crime.

    "How is that possible? Are you all sure to read it carefully?"

    "Brother Lei, we brothers have worked together not once or twice. I can guarantee that not a single frame has been missed." The person who spoke was the deputy squadron leader of the criminal police squadron.

    Fat Lei frowned: "No, could it be that the murderer didn't leave the collapse area after killing the people?"

    With doubts, Fat Lei divided the video from the second day after the incident.

    The investigators who were responsible for each picked up the Red Bull in front of them one after another and prepared for the second round of browsing with full energy.

    Half an hour, 1 hour, 1 and a half hours, 1 hour and 45 minutes, the minute and hour hands of the clock rotated rhythmically on the dial. At this time, Pang Lei changed his usual playful attitude and stared at the big screen with a solemn expression.  .

    Suddenly, the 12 sub-shots on the big screen went out at the same time. The video on the second day of the incident still found no abnormalities.

    Fat Lei picked up the phone and called me to the video analysis room.

    Looking at Fat Lei¡¯s ferocious expression, I asked curiously: ¡°Brother Lei, why did you call me?¡±

    "Xiaolong, tell me, are you sure that the murderer escaped from the southwest?"

    "Why do you ask that? Weren't you also there when the shoe prints were taken? The shoe sole patterns on the shit were left by the murderer, and the toe of the shoe points to the south. It must have been from the southwest entrance."

    Fat Lei paced back and forth in the room, looking restless: "It's strange, we have browsed the videos 48 hours after the incident, and there was no trace of the suspect at all. Could it be possible that the murderer grew wings and flew?"  "

    "Probably not."

     ?Pang Lei was a little angry: "This grandson has such a rigorous plan and his mind must not be simple. Do you think he deliberately left a shoe print to disrupt our investigation direction?"

    "No." I replied with certainty, "The suspect would not choose something as distinctive as dog shit if he had to disguise himself. And how could he ensure that we could still see this shit so many days after the incident?"  Dog shit? After all, dog shit is outdoors, and rain and strong winds can make physical evidence disappear. So the possibility of the suspect doing it intentionally is zero. I stick to my judgment that he left 100% on foot from the southwest entrance."

    Seeing my resolute attitude, Fat Lei raised his lips and said, "Humph, it seems that the murderer played a little trick of time difference."

    The "time difference" mentioned by Fat Lei is a means of evasion that we often encounter. The most classic case is a series of burglaries investigated by the Criminal Police Team last year.  This is also the longest theft case ever investigated by the Criminal Police Team.  The reason is that the suspect took advantage of the "time difference" to deceive the suspect.  The suspect would bring a large amount of food with him every time he committed a crime. After the theft was over, he was not in a hurry to leave the community. Instead, he would find a remote corner in the community to hide for a day or two. After the incident subsided, he would blend in with the residents.  Leave the neighborhood.  The advantage of doing this is that you can cleverly avoid the prime time of police investigation.  But as the saying goes, "You will never survive if you commit a crime." Using this routine every time a crime is committed will naturally arouse the vigilance of investigators. After several months of careful investigation, the suspect cannot escape the law in the end.

    Since the exit has been confirmed, Pang Lei has reason to suspect that the murderer is playing "time difference".  Three and a half hours later, the speculation became reality.

    "My dear, as expected, your fat man was right. This grandson left at 4 a.m. on May 2nd. He is so arrogant that he actually stayed in the subsidence area for nearly 4 days." Then, Fat Lei will lead  The video of the suspect was dragged into the processing software. After repeated debugging, the originally blurry surveillance gradually became clear.  After smoking a cigarette, Fat Lei clicked the "output" button, and the video was converted to a new folder under the cover of the progress bar.

    The processed image is only 1 minute and 45 seconds long. Double-click to play. The suspect is seen climbing over the railing and walking to the southernmost side of the highway with a rectangular object in his hand. After 1 minute and 20 seconds, a car stops and the suspect leaves in the car.  Because the infrared probe displays a black and white image at night, the captured image is not ideal.

    Brother Ming played the video repeatedly and then said: "We can extract several key points.

    ¡°First, through analysis of clothing style and walking posture, the person on the picture is 100% the suspect.

    "Second, when the car's high beam is illuminated, the rectangular object in the suspect's hand undergoes specular reflection. Using the arm as a reference object, the object is about 50 cm long and 30 cm wide, a bit like a glass photo frame. Ding Sheng's car  There is no such thing, it must have come from the subsidence area.

    "Third, the suspect did not wear gloves when he climbed over the railing. Xiaolong, I leave this to you."

    "clear!"

    Ming Ge opened the electronic map, wrote a number "5.6" on the white paper, and continued: "The fourth is the car the suspect took. The taxis in our city are mainly Santana and Chery, and they are all equipped with overhead lights and surveillance cameras.  Regardless of the appearance or logo, this car does not belong to the category of taxi. It is suspected that it is a private car.

    "At 4 o'clock in the morning, there was not much traffic on the road. I drove straight west for 5.6 kilometers along this road. There was a bayonet camera. The speed limit on the entire road was 70 kilometers per hour. If the car was traveling at full speed, then it  It takes 4 minutes and 47 seconds to reach the checkpoint. Then, as long as you keep track of the time and check one by one, you can screen out the suspect vehicles." (Remember the website address: www.hlnovel.com
