"Go on!" Elder Liang looked at me curiously.
I said, "Normally, if a bit drills into a human body, the bottom of the hole will create a weak pit because the front end of the bit is pointed. But in these holes, I don't see any holes like that. What kind of drill bit could produce such holes? "
I was puzzled, because I was not a professional in engineering machinery, and some of my knowledge was still weak.
Everyone fell silent while I continued to observe the corpse. Suddenly, I saw the big tray with the lotus seeds. It seemed that there were some thin wires inside. I picked up the tweezers and picked up the wire.
From what I can see, the wire is about a millimeter in diameter. The thin wire I picked up was a ring buckle made of three strands of thin wire. The buckle was done in a very orderly manner, it should have been made by twisting a nail around a thin metal wire.
The ring had been cut off, the cut was neat and tidy, probably by some sort of pincer. I was curious as to what the ring was used for, so I asked, "Were these also found on the corpse?"
"Yes!" A young medical examiner came over and pointed to the back of the body. "When the body was found, the victim was standing, tied to a flagpole rope. The killer first penetrated the skin of the victim's spine with a kind of needle about two millimeters long, then wrapped the victim's body with a thin wire and tied it to a rope. "
"So that's how it is!" Due to the many holes on the surface of the corpse, there were some small traces that I didn't notice. I held the magnifying glass and looked up and down the dead man's spine. Indeed, as the young medical examiner had said, every two centimeters or so there was a small hole in the victim's spine from top to bottom.
At this moment, I finally understood that the culprit used this method to transport the corpse to the top of the flagpole. No wonder I felt that there was something strange about the place.
The dead man's body weighed 50 kilograms. If he didn't use this method, the body would definitely fall off. If he tied a rope to the body, it could also cause the body to fall off.
Just then, Wei Shijie put down the camera in his hand and walked over. I saw him pick up a pair of tweezers and pick up a ring clasp from the tray. After examining it closely, he said, "This button should be the one used to tie the steel bars on the construction site!"
"Oh?" "Are you sure?" I asked.
"Of course I'm sure!" Wei Shijie put down the tweezers, and said: "When I was working frugally, I went to the construction site to move the bricks, and I saw that the steel bars on the construction site were usually tied with this kind of button. They usually held a string in their left hand (thin iron wire) and a special hook in their right hand.
Wei Shijie took out a data cable from his computer pack and said to everyone, "Let's compare this data cable to a tying string."
Immediately after, Wei Shijie folded the data line horizontally, and went around the leg of the bed. Then, he stretched out his right index finger to make a hook. Then he hooked his index finger around the fold of the data line, gripped the root of the data line with his left hand, and wound the root of the data line around the tip of the index finger. Finally he looked at us and made a twisting motion.
I suddenly realized that Wei Shijie's movements were practically identical to the buckles on the corpse. Wei Shijie's face did not look too good. I walked to his side and helped him up, saying: "The murderer is a construction worker?"
"Not necessarily!" Wei Shijie interrupted and said: "According to my knowledge, all of the workers at the construction site would use this type of tool."
"This is a good start!" Professor Liang laughed and said: "We can reduce the identity of the culprit to a minimum. First, the holes in the body of the deceased were made with an unknown drill bit, related to the project. "Second, the buttons on the body of the deceased were commonly used at construction sites and were also related to the project."
"One more thing!" Liao Mengfann also walked over and said, "Based on the location of the corpses, the killer is very familiar with the stadium. I think the culprit should have participated in the construction of the stadium before, it is very likely that it was the workers at that time."
I agree with Liao Mengfann, although the identity of the victim isn't clear, but with Zhang Tianyang there looking into the matter, they should be able to find out very quickly.
I think we need to go to the Construction Bureau of Yongan City and check out the construction company that was responsible for building the Lotus Stadium. We might even be able to find some clues.
Cough cough cough!
Just as I spoke, Professor Liang suddenly started coughing violently. Liao Mengfann ran over to his side and gently patted his back.
After the incident, I found that Elder Liang's body was getting worse with each passing day. His head was full of white hair and his face was full of wrinkles. At this age, it was supposed to be the time to retire and raise flowers, but he had to run around with us and suffer.
Ever since I was young, he had watched me grow up, almost like my grandfather. I walked up to his side and supported his shoulders as I asked, "Grandpa Liang, you …." Are you all right? "
"I'm fine!" Elder Liang gasped for breath, then said: "There's something wrong, Little Wei, come over." He waved at Wei Shijie and said: "There's nothing much to do now. When you return to your office later, go and check the types of drill bits on the internet and analyze what kind of drill points can drill out the same holes as the corpse."
Elder Liang looked at Liao Mengfann and I, and laughed: "The two of you are good partners, after you go to the Construction Bureau to get the information on the construction company, remember to ask around at the construction site to see if anyone knows about this drill bit."
Liao Mengfann and I nodded strongly, and then, we supported him out of the Dissecting Room.
After exiting the Medical Examiner's Office, I let Wei Shijie carry Elder Liang back to his office to rest first. On the other hand, I was prepared to give Huang An a call. It had been almost two hours since we parted, and it was already dark. I looked at the time and saw that it was 7 o'clock in the evening.
The phone call quickly ended. Brother Huang picked it up and asked: What's the matter? Little Chuan? "
I asked, "Brother Huang, have you found anything?"
Brother Huang said, "I found some. According to the residents around the stadium, about ten days before the incident, there was a trash collector here. An old lady even sold him an abandoned freezer."
"A freezer?" I was shocked and asked, "Did the woman who sold the freezer say what she looked like?" "How old?"
"Sigh!" Brother Huang sighed, and said: "That trash's face is covered in black paint, I can't tell what he looks like at all, but auntie said that the trash's accent is the same as the local one!"
"Locals?" I asked, "Are there any surveillance videos around here?"
"Of course not!" The Brother Huang said, "Lotus Stadium is surrounded by shantytowns. This place is currently being demolished and renovated."
"Oh?" I asked, "Are there a lot of construction sites around here?"
"Yes!" Brother Huang said, "Let me take a look and see if there are more than 100 buildings under construction!"
As I was speaking, I heard the sound of a large truck coming from Brother Huang's phone. It seemed that the construction site was working all night.
After hanging up the phone, I looked at the time helplessly. It was already 7: 10 in the evening. The Construction Bureau would definitely be off work early, but we wouldn't be able to wait for the case to come out. Using my luck, I dialed Director Ding's number.
"Hello? "That person?" Director Ding's tone of voice sounded a little tired. It seemed like he was in for a hard time today.
"It's me, Uncle Ding. Lu Xiaochuan of Task Force." I said politely.
"Ah?" Oh, so it's Little Chuan. Ai, I've been busy all day, have you eaten? "
I smiled in my heart, but was quite touched. Director Ding was not bad, I said: "I've already eaten, please do me a favor!"
"Say, all the police in our Yongan city will cooperate with you in your work!" Director Ding said resolutely.
I heaved a sigh of relief and said, "We suspect that the culprit was a worker on the construction site, so I wanted to go to the Construction Bureau to check up on the information of the construction company that was responsible for building Lotus Stadium. However, it's time to get off work now."
"Have you found it?" "So fast!" The Director Ding was very excited and said: "Don't worry, at most 20 minutes, I will have the Construction Bureau's people wait for you inside the unit."
After Director Ding finished speaking, he immediately hung up. I rubbed my stomach that was already starved to death, then said to Liao Mengfann: "We have 20 minutes to rest, why don't we go eat?" I pointed to the entrance of the Public Security Bureau, where I saw the Yunnan Crossing Rice Line.
She nodded and we walked side by side. I noticed that Liao Mengfann's expression was a little disappointed, so I asked: "What's wrong? Are you unhappy that I called you that? "
"Ha!" She smiled and said, "That's not what I meant. I feel that it would be very sad if this case were to be exposed by us."
"Grief?" I subconsciously held her hand. I saw a complicated look in her eyes, but she didn't struggle free. I was a little pleased and comforted her, "It's said that women are emotional creatures. I finally got to see it today."
"Ha ha!" She forced a smile and said, "There is a secret story behind every case. Actually, deep in the heart of the murderer, there is also a trace of conscience."
We sat across from each other at the table in the Rice Noodle Shop. I helped her open a bottle of Minnesota and handed it to her. "No matter what the reason is, no matter how kind the murderer was before, killing him is still murder. Since they chose this path, it doesn't deserve our sympathy."
Liao Mengfann took a light sip of the drink, and helped me pour a cup. "You're really suitable to be a police officer!"
"Ha!" I smiled playfully and shook the cup in my hand. "Actually, you're suitable to be a writer!"
I thought that Liao Mengfann would tease me, but who would have thought that she stroked her black hair with one hand and turned her head towards the window, looking at the traffic outside, she said softly: "If I don't become a police officer, what else can I do?"
