Chapter 56 Chapter Fifty-Five

At noon the next day, the police from the county bureau came to report to Gao Dong that a family in the village had picked up two pulleys and a long rope a few days ago.The two pulleys are the same size, with a diameter of more than 20 centimeters, which are commonly used pulleys on the rails of fishing boats.The long rope is more than 80 meters long. It is a green chemical fiber rope used on fishing boats, and its fastness is extremely high.The villager picked it up on a tidal flat piled with rubbish next to the village. Gao Dong was very excited, and praised the work efficiency of the criminal investigation team of the county bureau in front of Jiang Wei.

This result is completely consistent with his reasoning, which proves that his judgment is completely correct!And the fundamental starting point of all this is the "impossible crime" that Shao Xiaobing was able to commit suicide by jumping off a cliff while there was only the murderer's footprint on the hillside.What makes all this reasonable is that the murderer left the iron hook nailed into the cliff and the rope marks that he accidentally stepped on.There is no other way to achieve this "impossible crime" than to use a pulley device. No matter how perfect your criminal plan is, it cannot be implemented 100% as imagined.The iron hook was driven deep into the cliff, and it was difficult to remove.The more than 80-meter-long rope is in operation, and it is dark in the middle of the night, so it is inevitable to step on it.

Although other details were handled meticulously, as long as there is even one mistake, it is enough for the police to come back. On this day, the morale of the entire task force was greatly boosted.They knew that the pulley and rope were fishing equipment at a glance, and they had to go to a fishing supply store to buy them. So Gao Dong hurriedly arranged a large number of police forces to go to fishery supply stores throughout the county to check.The county is not close to the sea, and there are basically no fishery supply stores in the county. Shitan Town, more than 30 kilometers away from the county, is a well-known fishing port in the country. There are thousands of fishing boats and tens of thousands of fishermen in the town. There are many fishery supply stores there. innumerable.

This time the police were surprisingly lucky, and they got the news that night that the two pulleys and ropes were sold by a fishery supply store in Shitan Township twenty days ago. The reason why the boss remembers this business is because usually fishermen and some wage earners on fishing boats come to buy things in their shop, but that time, the person who came was a gentle young man, about thirty years old, who was very interested in the people on the fishing boat. I couldn’t name the supplies accurately, but I just gestured to buy pulleys and net ropes. The boss asked him what type of pulleys he wanted to buy, but he couldn’t name them, so he just asked the boss to take out a few. Later, he chose the ones with a height of more than 20 centimeters. , bought two, and bought more than 80 meters of rope.

The boss couldn't remember the person's appearance, but he only remembered that he looked polite and spoke the dialect of the county.The county seat of Ning County is in the north, Shitan Town is the second largest town, and in the south, the dialects in the south and north are different.The boss still remembered that this person came by car, but he couldn't remember exactly what type of car it was. The only regret is that there is no monitoring in the store, and there is no monitoring near the road outside the store. Although the person's appearance and what kind of car he drives are still unknown, today's investigation has greatly narrowed the scope.

This person is from around the county, about 30 years old, 171 to 175 in height, 120 to 140 catties in weight, has a car, has a background in science and engineering, has a solid memory of mechanics knowledge, and should be able to perform calculus calculations. Gao Dong carefully imagined the overall outline of the murderer in his mind. What is the identity of a thirty-year-old who still remembers calculus? Teacher, very likely.But there are at least 300 to 400 male teachers in their thirties in primary and secondary schools near the county town, and at least 200 to 300 people majoring in science and engineering. It will take a long time to carry out the investigation work one by one.

Engineers, quite possibly too.But which units have engineers is more difficult to count. Maybe it's a guy who just graduated with a master's or Ph.D. This kind of person will naturally remember this knowledge soon after graduation. Of course, the murderer may not be any one of the above three types of people. Maybe the knowledge is particularly solid when he was studying, and he will still remember it after a few years. For the time being, there is no way to completely outline the murderer, but Gao Dong knows that he is very close now, only one step away. He hurriedly ordered to match the characteristics of the murderer to all the people who knew Hu Haiping and Shao Xiaobing, and check them one by one. As long as he found someone with similarities, he would immediately focus on the investigation.

Now, two major puzzles remain. One is where did Shao Xiaobing's wife go?It was as if she had disappeared out of thin air, without any clues.Even though the process of Shao Xiaobing's suicide was clearly analyzed, it seemed that all of this had nothing to do with his wife's disappearance.What unsolved key clues are there? Another question is, what happened at Shao Xiaobing's house that day?The only evidence is that a sofa cushion was missing, and a dagger was stabbed several times under the next cushion. Shao Cong said that three gold bars were missing. The residents downstairs heard explosions that afternoon and plates overturned at night.Which of these clues are related to the case, and what is the degree of connection?

If this issue is also clarified, Gao Dong believes that the identity of the murderer is also completely ready to be revealed. Well, I'll go to Shao Xiaobing's house to check again tomorrow morning. It will be New Year's Day in two days. After New Year's Day, the last walk in the city has been dealt with. The provincial department and the ministry will put pressure on me. There is not much time left. The murderer must be caught as soon as possible. Gao Dong sighed and gritted his teeth at the same time.
