At this moment, Han Caiyan rushed in with two thick diaries in her arms, his face was flushed, he wiped the beads of sweat on his forehead, and said, "I always feel that Ji Yingxun died strangely. ”

Cha Min and Ko Se-yeon looked at Han Chae-yeon at the same time, she pondered for a moment and said, "If you think about it carefully, Ji Young-hoon recorded in the video pushed the door before he died and said, 'Let me in!'" Sobong! I know everything. I can do anything for you! What did he know? Could what he knew kill him? ”

"Oh!" Gao Shiyan stared at her eyes as big as a bronze bell in surprise, "Kill people and kill people!" Kang So-bong killed Namshin out of hatred, and when Ji Young-hoon found out, he killed him. ”

"It doesn't make sense. If the murderer is really Kang So-bong," Cha Min said, "On the day that Kang So-bong and Ji Young-hoon reported the crime, Ji Young-hoon stunned Kang So-bong and said that he killed Nam Shin by surprise during the struggle, and since Ji Young-hoon was willing to take the blame for Kang So-bong, Kang So-bong obviously did not need to kill Ji Young-hoon." On the contrary, Ji Young-hoon did not die, he carried all the charges, which was exactly the result that the murderer wanted. ”

"What if the murderer is someone else?" Han Caiyan raised her eyebrows and said, "If the murderer is someone else, the murder will be established." ”

"You mean," Gao Shiyan's big eyes flashed, and her long, thick eyelashes cast a shadow on her crimson cheeks like the wings of a pair of black butterflies, "The murderer of Nanxin is Kong Xue'er!" Kong Xueer and Jiang Subong are gay lovers, Ji Yingxun and Nanxin's intervention has become a bond between them, plus Jiang Sufeng's hatred for Nanxin is deep to the core, out of love for her lover and hatred between rivals, Kong Xueer killed Nanxin, but was misunderstood by Ji Yingxun as Jiang Sufeng's killing, she was worried that the paper could not hold the fire, and killed Liu Jianwu, which was both to kill the mouth and get rid of a love rival. Gao Shiyan was quite proud of her analysis, and raised her head slightly like a proud princess.

"Yo!" Forensic doctor Han Caiyan patted Gao Shiyan Zhuoru on the shoulder and quipped, "Sister, when did you open your mind?" I thought about it. ”

"But," Gao Shiyan frowned slightly, and said, "We have installed surveillance equipment at Jiang Sufeng's residence, and Zhao Xueshan actually killed Ji Yingxun under our noses, and the murderer is too exposed." ”

"What if she was deliberately exposing herself?" Han Chae-yeon clasped her hands on her chest and said, "She was very smart enough to expect from the beginning that the police would target the suspect as Kang So-bong, and that the police would install surveillance equipment at her residence, so she 'inadvertently' slammed the door and killed Ji Young-hoon." ”

Cha Min nodded thoughtfully.

Gao Shiyan blinked in confusion and said, "Why?" Why does she want us to kill people right under our noses? ”

"Ahem" Han Caiyan coughed proudly twice, saying, "There is an essential difference between intentional homicide and manslaughter, intentional homicide is murder, and the murderer is legally sentenced to death, while manslaughter is not out of the murderer's will, according to the severity of the circumstances, the murderer will only be sentenced to a few years in prison at most, and in some countries, he is not investigated for criminal responsibility." ”

"Oh!" Gao Shiyan nodded suddenly in realization, "Kong Xue'er wants to turn deliberate murder into murder, and the condition for this conspiracy to be established is the surveillance of the police, and we have become witnesses to her manslaughter!" If we don't see it, our investigation direction will be murder, even if we can't find evidence for a while, it will be difficult for her to get rid of suspicion, once she is established as a suspect, the police will do their best to track down the clues, and the danger of exposing the horse's feet is greater. Cunning, cunning! ”

"This is indeed an explanation, but, Miss," Cha Min patted Han Chae-yeon on the shoulder, "We didn't find any evidence at the scene to prove that Nan Shin's killer was Kong Xue'er. If the murderer of Nanxin was not Kong Xue'er, the next inferences would have been overturned. On the contrary, I have figured out what happened with the two unfamiliar fingerprints collected from the scene of Nanxin's murder. These two positions belong to Kang Su-bong, that is, Kang Su-bong once appeared at the scene, and she is the most suspicious. ”

"What do you mean by that?" Han Caiyan asked suspiciously, "I have already compared those two fingerprints with the fingerprints of the four people in this case, and none of them matched." ”

"The Mirror Principle." Che Min said, "We actually ignored such a simple mirror principle. Think about it, why do fingerprints stay on the wardrobe mirror? In fact, the mirror surface is smooth, so the fingerprints on the mirror are clearer than those left on other objects, so why did the murderer make the fingerprints clear? Of course, for the sake of easy identification, these two fingerprints are actually four fingerprints, and two fingerprints that are reversed 180 degrees coincide together, giving us the illusion of a new fingerprint. Why do such fingerprints appear? When we open the wardrobe, we naturally stand outside the wardrobe and open the cabinet door, and it is not surprising to leave fingerprints on the mirror surface of the cabinet door, but no matter how many times we open the wardrobe outside the wardrobe, there can only be overlapping or even overlapping fingerprints. ”

"If that's the case, then why is there a fingerprint that is reversed 180 degrees?" Han Caiyan asked thoughtfully.

This means that the person who left the fingerprint opens the wardrobe at a different angle and direction. Like, open from the closet? ”

"Ahh Han Chae-yeon exclaimed exaggeratedly, "I understand! Kang So-bong is hiding in the closet and opening the wardrobe door from the inside! ”

"Why hide in the closet?" Gao Shiyan didn't understand for a while.

"What if she did something unspeakable and happened to be bumped into, and she had to hide in the closet in a hurry?" Han Chae-yeon winked mischievously at Ko Se-yeon.

"Ahh Gao Shiyan suddenly realized, "When Jiang Subong killed Nanxin, she heard someone knocking on the door, and in a hurry, she hid in the closet, and this knocker was Ji Yingxun, and when he entered the house, Nanxin had already died, Ji Yingxun thought of Jiang Subong's bitter hatred for Nanxin, and immediately guessed that the murderer was Jiang Subong, so he wiped the fingerprints on the handle of the knife, cleaned up the traces of the crime at the scene, and immediately came to report the crime after forging the scene of the fight. Gao Shiyan proudly raised her eyebrows at Han Caiyan.

"That's what I thought at first." Che Min said, "However, I have checked the proof of Jiang Sufeng's alibi, and it is indeed impeccable." The nearby police confirmed that it was indeed on the afternoon of the day before yesterday, that is, on the afternoon of the day when Nanxin was killed, that is, there were indeed traffickers who went to the cramped corridor in front of the building where Nanxin lived to pick up the goods, and the police who were ambushed in the shadows witnessed: After the two groups of traffickers took over and discussed for a while, the traffickers who took over the generation carried a huge sack and stuffed it into the back compartment of the truck, and the police continued to chase and found that the truck was parked in front of a remote abandoned warehouse in the suburbs, and the sack was carried into the warehouse. Because there were not enough people at the time, most of the police force continued to track the traffickers, leaving only two people in charge of rescuing the hostages. When two police officers unlocked the warehouse door, the hostages were nowhere to be found. These circumstances coincide with Kang's description, that is, she is not lying. Her absence proved flawless. What is puzzling is why there are so many flaws in Jiang Sufeng's oral statement when he reported the case? It's as if she's deliberately trying to make people think she's lying. But why did she do that? ”

"So, don't get complacent too soon." Han Chae-yeon pointed to the two diaries on Ko Se-yeon's desk and said, "In criminal psychology, the inner world of a character often best reflects the essence of things. ”

"What is this?" Gao Shiyan picked up the diary and flipped through it.

"Diary." Han Caiyan smirked, "I stole it from Jiang So-bong's house just now. ”

Gao Shiyan raised her thumbs, "Awesome!" At this time, Gao Shiyan looked in pain, "My stomach hurts, I go to the toilet." ”

Han Caiyan glanced at Gao Shiyan, "The analysis is almost exciting, but you have to go to the toilet, haha." ”
