    Facts have proved that Lao Xian¡¯s inference was correct. Brother Ming found the murder scene 300 meters away from the leather shoes.

    The suspect chose the place of murder near a ditch. If it weren¡¯t for a pair of tattered long johns hanging on a cattail stick by the ditch, it would have been difficult to find the place.

    Taking the ditch as the coordinate, walking 10 meters south, you will find a large patch of dried blood. Judging from the concentration of blood stains, it appears that it has been washed repeatedly with water.

    Lao Xian picked up the weeds and carefully observed the cracks on the surface: "When the surface particles of the soil meet water, they will gather together due to the tension of the water, forming a mud layer. The mud layer will crack under the action of light and evaporation. Cracks  The size of the surface is directly proportional to the water consumption. From this analysis, the suspect has a large-capacity water storage tool."

    Fat Lei clapped his fingers after hearing this and said: "Professional tools for picking locks, blunt instruments for hitting the deceased on the back of the head, ropes for tying up the deceased, sharp instruments for murder, and now here is a water storage tool. How many of them did the suspect prepare?"  Guy?"

    "The more guys you bring, the bigger the target will be. Brother Lei, have you found any suspicious targets in the surveillance near the island?"

    Fat Lei pointed at his bloodshot eyes: "How can I finish watching a video of more than ten gigabytes so quickly? Give me some more time."

    Brother Ming¡¯s voice came from the side: ¡°Xiaolong, let¡¯s see if there are shoe sole patterns on these?¡±

    I walked over after hearing the news.

    ¡°Here, on this pile of plastic pieces.¡± Brother Ming said again.

    I picked out a few larger plastic pieces and observed them carefully under a magnifying glass: "The pattern and the suspected shoe print can be aligned. I will then measure the spacing between the patterns." As I said that, I took out the vernier caliper and measured carefully. After several calculations,  , I came to a definite conclusion, "What is left on the plastic piece is the suspect's shoe print."

    Brother Ming patiently put the plastic pieces together: "The water container was a plastic basin. After the suspect finished handling the scene, he crushed the basin and threw the edge of the basin into the ditch. Only a small amount was left here.  The pelvic floor fragments show the suspect's anti-investigation capabilities."

    Pang Lei opened the measuring tape and placed it on the pattern pieced together by Brother Ming: "My dear, it's almost 40 centimeters in diameter. How did the murderer bring such a big plastic basin?"

    Lao Xian picked up the plastic residue, looked at it carefully and said, "This is a raw plastic basin, which is no longer available on the market."

    ¡°Brother Xian, what is raw plastic?¡± I asked curiously.

    "From a chemical point of view, raw plastic, also called thermosetting plastic, is a polymer compound. This plastic is relatively hard and cannot be recycled after one-time molding. In contrast, cooked plastic is a plastic linear polymer compound.  Cooked plastics have properties such as tensile resistance, compression resistance, torsion resistance, and bending resistance. Common ones include polyvinyl chloride, polystyrene, etc. In the early years, due to backward production technology, raw plastic products occupied the market for a period of time, but now they have long  Disappeared."

    "Brother Xian, are you saying that the plastic basin used by the suspect was not purchased from the market?"

    "At least I can't buy it." (Remember the website address: www.hlnovel.com
