    Faced with three problems that ordinary people cannot solve, Mingge quickly gave solutions:

    First of all, the lacerations on the neck of the corpse were very flat, indicating that the neck was pulled over a large area during the fall.  Under the same traction force, the thickness of the rope determines the size of the traction surface, so the rope used by the suspect will not be thin.  By screening the types of ropes sold on the market, it was finally determined that the suspect may have used a medium-sized cable, which is slightly thicker than a thumb, has 8 strands in total, is orange, and is often braided.

    Secondly, if you want to completely separate the deceased's neck, you need a large enough traction force. According to Newton's law, f=ma (where f refers to the resultant force on the object, m represents the mass of the object, and a is the acceleration of the object). The traction force  The size is proportional to the weight of the falling object.  It is impossible for the suspect to throw such a high-quality heavy object and can only push it into the water along the bridge deck, so the falling object must be directly below the dumping point.

    Combining the above two points, the frogman only needs to tie the safety rope and follow the fixed route to find the falling object and the orange cable to determine the place where the body was dumped.

    Two days later, Ye Qian called. After screening, they finally determined the location of the body dumping point. When we arrived, the salvage team had used a crane to lift out the fallen object that had sunk to the bottom of the river: a half-ton stone.  lion.

    This is a closed stone bridge with a bridge deck of about 5 meters wide. It is built at the narrowest point of the Sishui River. The two ends of the bridge connect the Yunxi City Heba on one side and the Hebei Village in Dongshan City on the other side.  The bridge deck of the stone bridge has been spray-painted with black paint with the word "demolished" in large letters. In order to prevent people from passing through, iron railings and exposed locks are installed at both ends of the bridge.

    Brother Ming: "Ye Qian, please tell us in detail the process of discovering the scene."

    Ye Qian: "We will investigate the stone bridges one by one according to the characteristics you described, from near to far. This stone bridge is the last one in our Yunxi City. There has been news that the stone bridge will be demolished for a long time, but it has been shelved due to funding issues.  "When the nearby villagers learned that the stone bridge was going to be demolished, they came up with the idea of ??building a stone lion on the bridge."

    "Stone lion? What can this thing do?" I looked at the big guy on the roadside in confusion.

    "It is said that it is placed at the door to ward off evil spirits."

    ¡°I¡¯ll go, there are really people who want everything!¡±

    Ye Qian: "Originally, there were 12 stone lions of different shapes on each side of the bridge. Later, the villagers cut them off with electric saws and placed them in front of their homes. Those villagers who did not take advantage began to report, and the township government continued,  If the stone lions were not returned voluntarily, they would be compensated according to the price. As a result, these stone lions were returned by the villagers overnight, as were the ones scattered across the bridge. Later, in order to prevent this from happening again, the government  The two ends of the stone bridge were locked with iron railings."

    "How long ago was it locked?" I am very concerned about this question.

    Ye Qian: "It must have been many years. I don't know the specific time."

    "That doesn't make sense." I took out the tool and swiped my fingerprints on a brand new lock at the south end of the bridge.

    Ye Qian: "Xiaolong, is this left by the suspect?"

    "Didn't you notice that the metal objects around are all rusty, but this lock is somewhat 'unstained' even though it emerges from the mud?"

    Ye Qian: "It's true."

    "Our Yunxi area is full of chemical factories, and the rainwater is acidic. No matter how anti-rust the lock is, it cannot withstand the erosion of two acid rains. This lock must have been replaced by the suspect."

    Ye Qian: "Does this lock have any direction?"

    I used hydraulic pliers to cut off the lock, and after careful observation, I replied: "A very common three-ring lock, which costs 10 yuan a piece, and is sold everywhere." After that, I walked forward for another ten meters and came to that place.  In front of the stone lion that was only salvaged: "The suspect tied it with a porter's knot. This kind of knot has a characteristic. The harder it is tied, the tighter it is. The suspect must have done farm work."

    After Fat Lei took the photo, he glanced at me: "Everything outside is done, go in and take a look."

    The stone bridge deck is paved with the oldest blue bricks. Due to the immature caulking technology, the bridge deck is full of potholes. But to my surprise, a series of clear footprints were left on the bridge deck.

    Fat Lei was very excited: "Hey, I really want to thank the villagers who stole the lion. If they hadn't secretly sawed off the stone lion, there would never have been such a thick stone powder left on the bridge."

    "Besides, I also want to thank God. Fortunately, it hasn't rained in recent days."

    "'The Skynet is vast, and there are no omissions.' Even God is on our side. It seems that the day of solving the case is not far away." While Fat Lei was taking pictures with the camera, I had already measured the shoes.  Multiple sets of data were printed and analyzed.??Conclusion: "Size 39, middle-aged female, about 1.7 meters tall, cheap sneakers, low economic level."

    Fat Lei put away the camera: "Although we have the suspect's fingerprints and shoe prints, we still have no clue about the source of the body. To put it bluntly, we still don't know who died, which is embarrassing."

    "If you know who the deceased is, you may be able to catch the suspect." Brother Ming took over the conversation, "The deceased had sex before he was killed. Now Xiaolong has confirmed that the suspect is a woman. So under what circumstances can a man and a woman have sex?  Sex?¡±

    Fat Lei responded quickly: "Lovers, couples, hooking up, and prostitution, there are no more than these four situations."

    Brother Ming was a little confused: "If he was killed during a hookup or prostitution, why didn't the family of the deceased report the crime for so long? If they were lovers or husband and wife, the age difference between the two was quite big. Moreover, the woman's economic level was not the same.  It¡¯s not very high, so there shouldn¡¯t be a nurturing relationship.¡±

    Jiao Lei: "Brother Ming, haven't you heard that 'female juniors hold gold bricks'? What if that's what they do?"

    I curled my lips: "Judging from the bone development of the deceased, he was under 25 years old, and from the analysis of the suspect's footprints, she is definitely over 35 years old. The age difference is close to one round."

    ??Pang Lei smacked his lips: "Hey, dear, I'm just one round away from holding 4 gold bricks!"

    "I think something is fishy." Brother Ming broke the relaxed atmosphere created by Fat Lei with one sentence, "Xiaolong is right, the age difference between the two is at least 12 years. Unless it is a special situation, it is not consistent with common sense. There must be something in it  There are situations that we don¡¯t have control over.¡±

    Ye Qian: "Director Leng, what should we do next?"

    Brother Ming stood at the head of the bridge and carefully looked at the east-west concrete river dam in the southern section of the bridge: "I have walked this road before fishing. From here, 20 kilometers west is the territory of Dongshan City. Compared with our Yunxi City, that  The border economy is still relatively backward. The newly built river dams in our city are all smooth cement roads, but in Dongshan City, they are still uneven mud roads.

    ¡°The hot stamping on the inside of the corpse¡¯s calf is even and without overlapping, indicating that the suspect did not experience violent bumps while driving to dump the body. Based on this analysis, the route of dumping the body is still within Yunxi City. This is one of the reasons.

    "Secondly, the deceased had sexual relations with the suspect before his death. From the direction of the stabbing, the deceased was lying flat, so the murder scene must be in a closed room.

    "Third, the suspect is about 1.7 meters tall, only 5 centimeters shorter than the deceased. The deceased was thin. In a coma, a single person can commit the crime, ruling out the possibility of an accomplice.

    "Fourth, the deceased drank a large amount of liquor before his death and was in a state of deep drunkenness. In this state, he could not drive a vehicle and could only walk. The stomach contents were examined and it was found that the last meal the deceased ate was sheep and scorpions. So where is the store that sells sheep and scorpions?  It's not too far from the murder scene.

    ¡°Through motorcycle detection experiments, it has been determined that the murder scene is within a radiation circle with a radius of 36 kilometers.

    "We take the dumping point as the center of the circle and divide the circle into 4 equal parts. The northwest, northeast and southwest directions of Shiqiao are all under the jurisdiction of Dongshan City. They can be excluded. Then the killing place can only be 1/4 of the southeast side of Shiqiao.  Within the circle. Ye Qian, which police station does this area belong to?"

    "Taohuayuan Police Station."

    "Okay, you contact the director now and ask him to summon all the police officers in the station. I have something to ask."

    "No problem." (Remember the website address: www.hlnovel.com
