Serious Crime Unit 1

Chapter 1258 Devil and Angel (7)
"He is the elder brother. He was born only 5 minutes apart. Our family tradition is to give up the elder to the younger. His name is Lin Ke. Although Lin Ke did not grow up in our family, he was filial to us like Lin Feng. When he was 14 years old , my cousin told him: My wife and I are his biological parents, and he was so successful that he was admitted to Xiamen University and is now an assistant to Professor Li at the Provincial Institute of Biology. He was also named an associate professor this year."

"Great, congratulations on raising such an outstanding son! Have you tested the DNA of your two sons to see if they are identical twin brothers?"

"I don't know about this, and I haven't checked it. They are both in good health. Why check their DNA?"

"Okay, I understand. Thank you again for your cooperation!" After Jiang Yiming hung up the phone, he went to Luo Jin, explained the situation to him, and then asked him: "Are the DNAs of identical twin brothers exactly the same?"

"Their DNA is very similar, up to 99%, but there will be slight differences due to different living habits or different growth environments."

"Could it be Lin Ke who raped and killed Jin Xiaosu?"

"Most likely, other than that, I can't explain it."

"But Lin Ke is already married. He has a beautiful and virtuous wife, a pair of daughters, and has become an associate professor. He is a winner in life. How could he do such a heartless thing?"

"It is difficult to know the heart when you know the person. Have you forgotten the news that several judges of the Shanghai Higher People's Court engaged in prostitution together? They were well-dressed and sanctimonious during the day, but at night they ran out like rats in the sewer. Everyone made an appointment to go whoring together. One of the judges He also specifically wants to prostitute girls under 14 years old. He said that girls' vaginas are extremely tight... They are a group of demons!" Luo Jin's face was full of anger.

Jiang Yiming walked out of Luo Jin's office silently. He was very aware of the many dark problems in society. Recently, Sun Lijun, the former deputy minister of the Ministry of Public Security, was sentenced to death with a suspended death sentence for embezzling 6.46 million yuan. This is a true portrayal of the darkness and greed of human nature. Internet giant Sun Lijun not only embezzled, but also He seduced women, committed adultery with his subordinates, and kept many mistresses... and a total of 6 senior officials of his party were sacked... Thinking of this, Jiang Yiming felt an inexplicable sadness in his heart.

Jiang Yiming and Zhou Ting drove to the Provincial Institute of Biology.It is located on the southeast side of Laishan Mountain, adjacent to the Environmental Protection Bureau, and covers an area of ​​about 100 acres. As soon as you walk in, you can see the rockeries in the yard, koi carps swimming leisurely under the clear pond, and fountains flowing from the pond. The jet comes out, and there are flowers, plants and trees everywhere. The fragrance of flowers and leaves comes to your nostrils. The birds on the trees are chirping gracefully, and it is as quiet as a paradise.

They can only sigh at the beautiful scenery, because only big trees are planted in the compound and backyard of their city’s public security bureau, not flowers, and there are no rockeries or fountains.

They soon found Lin Ke. He was doing experiments in the laboratory and was called into the office by the director.Jiang Yiming took a look at him: He was about 176 centimeters tall and weighed about 70 kilograms. He looked exactly like Lin Feng. The only difference was that he had a short beard and short hair. He was wearing a white coat, a very ordinary T-shirt underneath, and a Loose trousers, slovenly look.

"Hello, we are from the Criminal Police Team of the Municipal Bureau, and here is my ID." Zhou Ting saw him standing there, a little dazed, wondering what he was thinking?
"Oh, hello, what do you want from me?" He even sounded like Lin Feng and looked a bit dull. He was not as smart and capable as Lin Feng. He liked to get straight to the point. It seemed that he was a very efficient person.

"Mr. Lin, please sit down and talk." Jiang Yiming said with a smile.

"I'm very busy. The students in the laboratory are still waiting for me to teach them how to do experiments. I hope you can speak clearly and concisely. I'm really sorry." He said sincerely with apology.

"Okay, let me make the story short. A girl named Jin Xiaosu was raped and killed in Shanqian Park in our city. We extracted the suspect's semen from Jin Xiaosu's body. After comparison, the suspect's DNA was found to be the same as your brother's. Lin Feng’s DNA similarity rate reaches 99.99%, but through investigation, we have eliminated Lin Feng’s suspicion. You are Lin Feng’s identical twin brother, so you are suspect.”

"What are you talking about? I'm going to rape and kill Jin Xiaosu? It's a fantasy! How do you know that we are identical twins, not identical twins? Even I don't know that I and my brother are identical twins." He was very Surprised, but not angry, and has a strong psychological quality.

"We are just speculating, so we need you to cooperate with the investigation."

"How to cooperate?"

"Extract your biological sample, detect the DNA, and then compare it with the DNA of the suspect's semen. If the similarity reaches a certain level, you are the biggest suspect. Please cooperate."

"Okay, hurry up." He thought for a moment and said, "The result will definitely disappoint you." Zhou Ting took out a cotton swab and extracted his saliva. After seeing this, he left without saying hello. It seems that I am rushing to reincarnate.Zhou Ting smiled and said, "Lin Ke is such a nerd. He doesn't even have the least courtesy. He doesn't look like an associate professor."

"The world is full of wonders, and everyone has their own personality. Many scientists are only addicted to academic research, have no social experience, and even have social phobia... However, he is really capable of becoming an associate professor at such a young age."

After Jiang Yiming returned to the team, he handed Lin Ke's biological samples to Luo Jin and asked him to detect the DNA as quickly as possible, then compare it with the suspect's DNA, and report to him as soon as the results were available.Luo Jin said that the results would be available in two hours.

When lunch was about to begin, Luo Jin walked into Jiang Yiming's office and said to him: "Lin Ke's saliva DNA has come out, and it is 99.99% similar to the DNA of the suspect's semen. It can be determined that Lin Ke is the suspect. Of course he It’s also possible that he was framed. Just like Hua Baifang framed him.”

"Okay, I got it. After lunch, Zhou Ting and I went to find Lin Ke. He was anxious to end our questioning of him. It turned out that he was avoiding us to prevent himself from saying too much and making mistakes." Jiang Yiming said.He thought about it and felt that Lin Ke didn't seem like a murderer who would rape and kill girls... But there are no absolutes in the world. Maybe his feeling was wrong, as Luo Jin said: It's hard to know the heart when you know the person!

Jiang Yiming and Zhou Ting appeared in front of Lin Ke again.Lin Ke frowned and asked: "Captain Jiang, have you eliminated my suspicion?" His voice was small but crisp. This time he was not as anxious as last time. Maybe he really did some experiments last time. Wait for him to do it.

"Mr. Lin, on the contrary, you have been listed as the biggest suspect by us."

"Why?" he asked calmly, looking very calm.

"Because the similarity between your DNA and the suspect's DNA is as high as 99.99%. If you don't believe me, take a look at the DNA test report issued by our forensic doctor." Jiang Yiming took out a report from his bag and handed it to Lin Ke to read.

When he took the report, he was a little surprised. After thinking for a long time, he said, "Could your forensics have made a mistake? There will be errors or mistakes in any technology, and the same goes for our experiments."

"You are an expert in biology. Of course you know that the technology for detecting DNA is very mature, and the error is less than one ten thousandth. Do you think we might have made a mistake?" Jiang Yiming looked at him coldly. Jiang Yiming's eyes looked at people. There are many types, and sometimes just one look can scare the criminal into confessing his crime quickly.

"Captain Jiang, you must have gone wrong somewhere. How could I kill someone? Let alone rape and murder... If you are not mistaken, I think there is another possibility..." He hesitated, It seems that he doesn't want to say it.

"What is the possibility? Don't worry, no matter who he is, no matter how powerful he is, we will not compromise with him." Jiang Yiming saw his ambivalence.

"After I graduated from university, I was hired as a researcher by the Provincial Institute of Biology. I felt very lucky, so I came up with the idea of ​​helping others. However, my salary was limited. I had to marry a wife, have children, buy a house, and buy a house. The car cost most of my wife and I's salary, so I have no way to help others financially, so I just want to donate bone marrow to leukemia patients..." He hesitated again, his face was very ugly, and it was obvious that he was feeling sad.

"Please continue talking, it will be of great help to us." Jiang Yiming looked at him sincerely, because Jiang Yiming had already guessed what he wanted to say.

"So, I made up my mind to come to the provincial hospital to donate bone marrow, that is, bone marrow hematopoietic stem cells. The weight of an adult's bone marrow is about 3 kilograms. A donation of less than 10 grams of bone marrow hematopoietic stem cells can save a leukemia patient's life. Life is extremely worth it, and I plan to save at least 50 people in my life. So, starting from 2015, I have been going to the Hematology Department of the Provincial Hospital to donate bone marrow and hematopoietic stem cells twice a year. A total of 16 donations." He stopped again.

"What do you want to express to us? It doesn't matter. You think slowly and speak slowly. We have enough patience to listen." Jiang Yiming saw that he was worried and continued to encourage him to tell the truth.

"What I want to say is that if a leukemia patient transplants my bone marrow hematopoietic stem cells, and he is a man, then his DNA may become exactly the same as mine, so the person you are looking for is most likely to be A leukemia patient who had my bone marrow hematopoietic stem cells transplanted... I thought I was as kind as an angel, but I didn't expect that I would indirectly create a murderous devil... Sigh..." He sighed deeply.

"Do you know who transplanted your bone marrow hematopoietic stem cells?"
