Serious Crime Unit 1

Chapter 76 Devil’s Eye (16)
Qu Liping is gone, Ouyang Shui is gone, and Lin Lang is gone. After Lin Lang left, I really feel the heartbreaking pain and the pain of loneliness. I always wonder: Why is Qu Liping still there? Won't you send me away?I really want to leave early and go to heaven to meet Lin Lang.I know many cases of murder after death. With Qu Liping's intelligence, she will definitely find a way to send me away.

But at this time, my classmate Yang Mingming came to the Yangtze River to see me. When she saw my haggard face and fallen hair, she was shocked and asked what was wrong. I refused to tell her. She was very angry and scolded me like a dog. My head was bleeding, but I didn't care at all. Just scold me, no one would scold me anymore in a few days.Seeing that I refused to say anything, Yang Mingming hired two extremely strong migrant workers at the construction site. They held me on the left and right and put me on the plane to Shanghai...

Seeing this, Jiang Yiming's eyes became wet, and tears fell on the diary, making the words on it wet...

After Jiang Yiming and Wu Jiang got off the plane, they went directly back to the team and convened a meeting with the key members of the task force. First, Jiang Yiming showed Sun Fangfang's diary to Zuo Li, Xiao Ke and Luo Jin. When they read it one by one, they were all sighing. Keeping shaking her head, Zuo Li couldn't help but burst into tears. This result was beyond their expectations and made them regretful. Does this mean that they have invested more than 50 police personnel and all their efforts in the past month will be in vain?Jiang Yiming asked them what they thought.

"What can I say? It's all a waste of time." Xiao Ke said.

"No, if we didn't cut our legs, how would we know that they were all the result of suicide? How to write a closing report? Now that it's done, this case has finally come to light. It can give a clear answer to the family of the deceased, and also to the people of the city. One explanation." Zuo Li said.

"Don't speak too soon, this case is far from over." Jiang Yiming said.

"Is what Sun Fangfang said in her diary false? Is she trying to protect the mastermind behind the scenes?" Wu Jiang asked.

"The diary should be authentic, but we need to do a handwriting appraisal to see if it was written by Sun Fangfang herself? In fact, from the tear-stained diary, we can already prove that it was written by Sun Fangfang. Our next task is to find out who committed the murder. There are four of them," Jiang Yiming said.

"Didn't they commit suicide? There are diaries to prove it." Xiao Ke was extremely shocked!
"They killed each other, no, we should say seeing each other off, but who lured them to the Carrot Cave? And who put the cobalt 60 in the cave? And it was packed in an exquisite copper box. The copper inside The packaging is very beautiful and carefully designed. The real murderer behind the scenes is to make them think that cobalt 60 is an expensive thing. Unfortunately, Lin Lang has thrown the copper box under the cliff. Finding it is like looking for a needle in a haystack. Also, What is the layer of cobalt 60 that Lin Lang scraped off with a knife? Why is cobalt 60 placed in that inaccessible cave? We must find this person, what is his motive for killing? And a series of other things We need to verify it," Jiang Yiming said.

"Captain Jiang, let me tell you a few words. Sun Fangfang's diary said that cobalt 60 will glow in the dark, but will not emit light when taken outside the cave. I judge that it is phosphorus. The murderer sprayed phosphorus on the cobalt 60, so it can It glowed in the dark, and Lin Lang also realized that it might be phosphorus, so he used a knife to scrape it off. After scraping off the phosphorus, he saw cobalt 60. In addition, we have a more important thing to do, and we must go to Sun Fangfang immediately. I went to her residence and searched her residence to see if there were gas leaks, peeling wires, food poisoning, etc. I guessed that Qu Liping was most likely to have tampered with Sun Fangfang’s favorite food, but she didn’t expect that Sun Fangfang had already She started to feel sick and didn't want to eat, so Sun Fangfang died in the hospital," Luo Jin said.

"Luo Jin is right. I was thinking just now, Luo Jin, after cobalt 60 reaches its half-life, where do units that use cobalt 60 generally discard it?"

"Usually it is buried deep in inaccessible caves, or deep in the desert. Our coastal city is far away from the desert. It costs more than ten to 20 yuan to process it, so many units of cobalt 60 are buried in caves where no one goes. , and the cave must be sealed and a warning sign prohibiting forced entry must be written.”

"Didn't Lin Lang and the others see this warning sign? I think the warning sign might have been taken away deliberately. Let's do this. We will divide our forces into two groups. Zuo Li and Xiao Ke will go to Sun Fangfang's residence to check if there are any fatal dangerous goods. I Go with Wu Jiang and Luo to conduct an on-site inspection of the Radish Cave in Konjac Mountain to see if you can find any clues."

Jiang Yiming and three others came to the Jiangzhen Police Station and asked the director to arrange for a policeman familiar with Luobo Cave to accompany them up the mountain. The director called a policeman named Zhu to accompany them.

Police Officer Zhu is over 50 years old. He is wearing a neat police uniform and is spotless. You can tell at a glance that he is a very dedicated person.As soon as Lao Zhu heard that they were going to Radish Cave and that it was about cobalt-60, he told them what he knew:

"It turns out that the cobalt-60 was buried in the carrot hole by the Second People's Hospital. In the autumn of 1999, Li Zhong, the chief physician of the hospital's radiology department, and two nurses went there together. They hired four migrant workers to carry a lead can up the mountain. For some reason, the leader of the Second People’s Hospital called our director and asked him to send two policemen to escort him. The leader of the People’s Hospital might be afraid that the villagers would not agree with them burying cobalt-60 in the carrot hole, so he asked us to escort him. ? It turned out that the journey was safe and nothing happened. After arriving at the Carrot Cave, the four migrant workers took out steel fibers, picks and other tools, entered the bottom of the cave, and started digging. According to Dr. Li's request, they dug a half-width meters, a pit two meters deep, and then threw the lead can into the pit, and then filled it with stones and soil. After doing this, the sun had set, and we went home." "The next day, Dr. Li called me and asked me If you are free, if you are free, I will accompany them to the Carrot Cave. I asked him why he was still going? He said that he would bring a welder to block the entrance of the cave. I didn't have anything to do at the time, so I went up the mountain with them again. , the four migrant workers also came, and there was an additional welder. The migrant workers carried steel bars and a large warning sign on their shoulders. After arriving at Luobo, the migrant workers followed the welders' instructions and used chisels to chisel the semicircular holes. Make 16 small holes, insert the steel bars, and then weld them together so that even rabbits can’t get into the holes.”

They had arrived at the Carrot Cave while they were talking. They put their survey tools on the ground and started surveying.There is no fence made of welded steel bars at the entrance.There is no warning sign, but 16 small holes for inserting steel bars are still there, and there is rust on the small holes near the foot of the holes, which shows that the iron fence was deliberately damaged.Maybe this person is the murderer.But it cannot be ruled out that it was stolen and sold as scrap metal by villagers who were greedy for petty gains.

"Lao Zhu, what material are the warning signs made of?" Jiang Yiming asked.

"The legs are made of steel bars, and the printing plate is made of aluminum sheet, because the People's Hospital is afraid that the iron sheet will rust over time."

It seems that this warning sign has the same fate as the steel bars sealing the hole.

After investigation, there were only four types of footprints outside the cave entrance. Although they had been washed away by many days of rain, they were still relatively clear. They judged that these four different footprints belonged to the four deceased people. But why didn't the murderer leave any footprints?Could it be that the murderer came to Carrot Cave very early?If you come to Carrot Cave for more than two months, the footprints outside the cave will definitely be washed away.

They investigated all the way until they found a pile of fresh soil at the bottom of the cave. Lao Zhu said that it was the pit where cobalt 60 was buried. Apparently, the murderer dug out the cobalt 60, sprayed it with phosphorus, put it in a copper box, and then put it in a copper box. Put it on the rock in the middle of the cave for Lin Lang and the others to see.

After an afternoon of exploration, they finally found a valuable shoe print in the cave and a hair in the mud.

Back in the team, it was already past the off-duty time. Zuo Li and Xiao Ke had not gone home yet. They were waiting for Jiang Yiming to come back and report the results of the search to him. Sun Fangfang lived in a single dormitory. There was no gas leakage and no wires. Problem, but they discovered the situation in Sun Fangfang’s favorite Dove chocolate, because there were dead ants on the torn chocolate, 5 in total. Apart from chocolate, there was no other food in her room, and they had Bring the chocolate back and let Luo Jin test it.In addition, Sun Fangfang's body has been transported, Zuo Li signed for it, and placed it in the autopsy room, waiting for the autopsy.

Judging from the results of today's investigation in Luobo Cave, it can be judged that the four deceased were homicides. Next, Luo Jin has the heaviest task. Luo Jin has to perform autopsies, detect poisons, and extract hair traces from the scene. Although Luo Jin is equipped with an assistant, but Li Xiaoqing was transferred to the crime evidence center from a low-level hospital. She is not proficient in forensic medicine and can only be Luo Jin's assistant. Sometimes she is not qualified to be an assistant. I heard that the former leader transferred her here Yes, it is easy to pick up a god but hard to send her away, but it is an embarrassing thing to transfer her away. Fortunately, Li Xiaoqing knows that his knowledge is not enough, so he often goes to the Forensic Medicine Department of the Police Academy to recharge his batteries. He doesn’t have much time in the laboratory a year, so Luo Jin often made noises to replenish their laboratory with fresh blood.

Jiang Yiming briefly talked about the investigation of Luobo Cave with Zuo Li and Xiaoke, and analyzed and discussed with each other where to start investigating the case.

"When the murderer went to dig for cobalt-60 in Radish Cave, he must have worn radiation-proof clothing. This type of lead-proof clothing that protects against X-rays is rarely sold in stores and is expensive. Check online to see how many stores sell it in our city. This kind of lead clothing leads to a much narrower scope and less detours," Luo Jin said.

"What if the lead suit worn by the murderer was stolen?" Xiao Ke asked.
