Talk About The Case

After receiving Yang Cong's call, Lin Xin hurriedly walked out of the Federal Police Station with him and ran towards Chen Chong's local police station.

Knowing the seriousness of the matter, both of them were tensed and silent along the way. Yang Cong gradually accelerated his driving speed. He was also very anxious in his heart. This series of children's murders made him feel helpless for the first time.

"Thank you, don't expect to see a corpse with only limbs and head in the end." Lin Xin suddenly said in the car.

"Sister Lin, what are you talking about?" Yang Cong asked.

Lin Xin sighed: "The first is a corpse without a head. The second is a corpse without legs. The third is a corpse without a pair of arms and an eyeball. This time Sun Junli's son has been exploded and disappeared. If this child is related to the case, then the next deceased will be him, and according to the murderer’s habits, he may take off the child’s body and leave his limbs and head at the scene of the crime."

After Yang Cong heard this, her face was green, and what Lin Xin guessed might be the fact.

"However, we must buy time to lock the murderer, because according to the inertia of the murderer, the murderer should let the child do the puzzle in three to four days, and then the child will be killed after the deadline of those days. As long as we can Find out the murderer at this time, then Sun Junli's son will be rescued." Lin Xin said.

Yang Cong nodded.

When they arrived at Chen Chong's office, it was already around five o'clock. Chen Chong took a photo lying on the edge of the table and pushed it in front of them.

Lin Xin looked closer and saw that it was a boy.

The boy in the photo is very cute and innocent. He grinned at the camera. The deciduous teeth in front seemed to have just fallen off. He was waiting for the growth of his front teeth. How cute he smiled.

Such a cute little boy, as long as anyone saw it, he couldn't bear to hurt him.

Lin Xin looked at the boy's photo, looked up at Chen Chong, and waited for him to speak.

Chen Chong took a sip of coffee, sighed, and said slowly: "The reporter was the Sun family. When Mrs. Sun came over, she looked slumped and lacking energy. I think it came from the fact that after the child disappeared, she didn't get a good night's sleep. As for Sun Junli, he has been silent, his expression is very deep, but from his sad face, he is also in panic and trouble because of the disappearance of his beloved son."

Lin Xin said: "Well, parents must be extremely anxious after their children disappeared. When was Sun Zhijian exploded and disappeared?"

Chen Chong replied: “According to Mrs. Sun’s confession, the housekeeper discovered that Zhijian’s disappearance was around 1 p.m. yesterday afternoon. Sun Junli was originally on a business trip, but because his son was sick, he also temporarily cancelled his trip. I went to work in my own company as usual, and was not at home in the afternoon."

"What about Madam Sun? Where was she then?" Lin Xin asked.

"As for Mrs. Sun, she drove to the supermarket to buy some vegetables after having lunch at about 12 o'clock in the afternoon. She said she would cook for Zhijian herself." Chen Chong said.

"They are in a rich family, isn't the housekeeper or servant buying these trivial food shopping? Why did Madam Sun go there in person?" Lin Xin asked curiously.

"She said that Zhijian’s condition has improved a lot, and she has promised her son to cook for him personally, so on a whim, she also wanted to personally choose his favorite vegetables and meat for him, so she went to the supermarket to buy these materials. . It’s just that after she returned home and looked for Zhijian everywhere, she discovered that he was missing.” Chen Chong said helplessly.

"Where are the housekeepers and servants? Didn't they find Zhijian missing?" Lin Xin frowned and asked.

“Because the front door of the Sun’s house is always locked, when Zhijian goes out to play, he will always be within the range of his home, and the farthest place to go is the flower garden in the courtyard. According to Mrs. Sun’s explanation, there is a flower garden in the garden. Zhijian always likes to play on the small swing. Since there is no possibility to go outside, they will not pay special attention to the whereabouts of the young master. Moreover, the housekeeper and the servants have their own job requirements. No one will pay attention to a child's activities at home." Chen Chong continued.

"So, is there a closed-circuit television outside home?" Lin Xin asked.

"Yes, but some places in Sun's house are blind spots, and CCTV can't be photographed. When we turned on CCTV, we found that the last place Sun Zhijian went to was the flower garden. However, when Sun Zhijian was ill, the home was here. A doctor will treat him." Chen Chong said.

Lin Xin felt nervous and asked, "That means that besides his parents and servants, the only stranger Sun Zhijian saw at that time was this doctor?"

Chen Chong nodded and said, "Yes, it can also be said that the last person Sun Zhijian saw before his disappearance was probably this doctor."

A vague thought flashed through Lin Xin's head, and she asked, "How long has Sun Zhijian been sick?"

Chen Chong said, "According to Mrs. Sun, he has been sick for almost four to five days."

Lin Xin frowned and said, "So long? What kind of disease is it?"

Chen Chong said, "It was originally a high fever, but later I experienced symptoms of diarrhea. That's why the illness dragged on for so long."

Lin Xin faintly felt wrong, she said, "That means this doctor has come to Sun's house several times, and perhaps he has already figured out the topography of the house clearly, so he knows the blind spot of the closed-circuit television. Look at it like this. Lai Zhijian’s disappearance may have something to do with this doctor. So, did Mrs. Sun say what the doctor’s name was? Which hospital sent the doctor?"

Chen Chong said: "Yes, the doctor who came to see Zhijian was named Cheng Yan, from Dongfang Hospital. Since this case involved the child’s limbs and head being cut, we have reason to believe that this disappearance case and the three others The child’s murder case may be related, and it is more likely that this doctor did it. Moreover, according to Mrs. Sun’s confession, the doctor had been in the room with her son. That’s why I put Officer Lin on you. Call it here."

Lin Xin immediately remembered Dr. Cheng Yancheng who had taken care of Leng Yu’s wounds when he heard him say this. But she didn’t know whether Cheng Yan was him, and the doctor Cheng Yan in Lin Xin’s impression was mature and serious. Actually like puzzles too?

She said: "Officer Chen, I may know this Doctor Cheng, can you call me the closed-circuit television and let me confirm."

Chen Chong said: "Okay."

After that, he took out the videotape and adjusted the scene of Dr. Cheng coming to Sun's house these days. However, Lin Xin frowned when she saw it. The figure and height of the person in the picture seemed to be a man, but other than that, she couldn't see her face at all.

I saw that he was wearing a windbreaker at home or outside, and deliberately or unconsciously lifted the hat of the windbreaker and put it on his head, and kept his head down all the way, avoiding the closed-circuit television.

"So cunning!" Yang Cong burst out this sentence suddenly.

"Officer Chen, there is no CCTV in the children's room, right?" Lin Xin asked

"Well, maybe the windbreaker was taken off after Doctor Cheng entered the child's room." Chen Chong said.

Lin Xin sat there thinking for a while, and said: "Officer Chen, I would like to trouble you to borrow your laptop to connect to the Internet. See if you can help me find the photos of Cheng Yan from Dongfang Hospital, and then print them out. Take the photo to the Sun family to confirm if it was this Doctor Cheng they met."

Chen Chong didn't say much, and immediately searched the Internet.

Usually such a large hospital will definitely have information on doctors and other medical staff online, not to mention that Cheng Yan is a well-known doctor in the hospital.

Sure enough, Chen Chong found Cheng Yan's photo. He pushed the notebook in front of Lin Xin, pointed at the person in the photo and asked, "Is it him?"

Lin Xin nodded and said, "Yes, that's him."

Chen Chong took the initiative to print out the photos and handed them to Lin Xin. Then, Lin Xin followed the address of the Sun family given by Chen Chong, and flew to the Sun family with Yang Cong.

On the way, Lin Xin dialed Mei Hua’s cell phone and said, “Mei Hua, please go to Dongfang Hospital with Sakura immediately to check if any doctors or medical staff have missed work from last week to today, because It was found from Officer Chen that the disappearance and the murder of a child may have a direct relationship with Dongfang Hospital, and the suspect may be the medical staff in the hospital, especially the whereabouts of Doctor Cheng Yan. "

After anxiously answered there, Lin Xin ended the call. She raised her hand and rubbed her temples, and finally saw a little eyebrow, unlike before.

Yang Cong said: "Sister Lin, if these children were really killed by Cheng Yan, what motive do you think he killed the children?"

Lin Xin said: "So far, I have not been able to figure out why he did this. The first thing is to let the children puzzle. This may be because Cheng Yan has a fanatical obsession with puzzles. But what is the purpose of the cut limbs and so on? , I can’t figure this out until now. If it’s because of the love of puzzles to combine the limbs one by one, what is it for? But, does he really combine the limbs from different children, we I don't know, because I can't find the missing limbs and heads."

Yang Cong said: "However, according to the forensic anatomy, the cut wounds are all flat. If you have good medical skills, you will need a very sharp knife. Now we are locked in to Dr. Cheng. It is a suspect, so it must be because of the superb medical skills."

Lin Xin gave a low "um". Then, she remembered that all the puzzle pieces she found from her children were pictures from a warm family. So he searched for Dr. Cheng's background, but other than showing his medical degree and other academic achievements on the Internet, there was nothing about his family background.

After half an hour, the two came to the Sun's mansion. Lin Xin looked at the house of the Sun family, and it was indeed the house where the wealthy family lived. The design and size of that house is like a palace, and ordinary people simply cannot live in such a house.

However, she didn't want to watch them, and rang the doorbell. After the walkie-talkie explained her identity, a housekeeper opened the door and let them in.

When they came to the hall of the house, they saw the Sun couple sitting on the sofa in the living room. Mrs. Sun’s eyes were red and swollen and she had been crying for some time, while Sun Junli was sitting aside comforting his wife.

Lin Xin sat across from them, and after briefly indicating her identity and intention, she said straightforwardly: "Mr. Sun, Mrs. Sun, we have obtained some information about Zhijian's disappearance from Officer Chen. We discovered that Dr. Cheng may be missing. The biggest suspect here. It’s just that we can’t accurately confirm his face from closed-circuit television, so I’m here to let you recognize his face from the photos."

After all, Yang Cong took out the printed photos and pushed them in front of the couple.

Mrs. Sun was crying while looking at the person in the photo. After watching for a long time, she suddenly looked up at Lin Xin and cried: "Officer Lin, the person in the photo is not Dr. Cheng who is treating Zhijian!"
