Let go of the murderer and let me come!

There is some light in the case, but you can't catch him if you think he is the murderer. You have to produce clear evidence.

After a whole night of hard work, I watched several videos back and forth countless times, Lin Sihang felt that the penis was about to fall off, "It's not over!"

Song Haozhe just walked in with breakfast when he heard Lin Sihang complain. He distributed the bought breakfast to everyone, and said slowly, "As long as you work hard enough, an iron pestle can be ground into a needle...you grind it slowly"

"Now it's been ground into a stick...Come here." Han Yue raised his head and dripped some eye drops into his eyes, grinning his teeth and said, "Did she answer the phone in the video in the park? I'm dazzled... Take a look."

Song Haozhe took a closer look, and then paid attention to the time displayed on the video, "Yang Yizong...Go and investigate Chen Hong and Chen Yan's call records at this time!"

"Go now!" Yang Yizong agreed, and ran out without eating.

"Damn it! I finally feel relieved..." Lin Sihang leaned back in the chair, "My mother will come over tomorrow...I have to find time to pick her up...This case is never over, I guess I don't even have time to see my mother! "

"You're allowed to take half a day off!" Song Haozhe made a cup of tea, "It's like a stick... It won't be far from the needle."

"That has to be grinded!...Ah!" Lin Sihang suddenly jumped up from the stool, "Damn it!"

"What's the matter?" Song Haozhe startled him, the hot tea in the cup almost scalded his mouth.

"Is there a rope in the evidence we collected? Regardless of whether she directly touched the rope with her skin when she killed someone, although nothing useful can be extracted!...but..." Lin Sihang deliberately put on a trick, watching the eyes of several people Looking over here, he raised his head triumphantly.

"Say it!" Song Haozhe patted Lin Sihang's butt.

"Tsk...you!" Lin Sihang dodged and stared at Song Haozhe.

Song Haozhe ignored it directly, "Don't tell me?"

"Are you sick?" Lin Sihang rolled his eyes. "What we have been doing is DNA testing, which is paternity testing...there is another kind, through Y chromosome DNA genetic markers, to determine whether there is a blood relationship."

"What's the difference between the two?" Fang Bo, Han Yue and the others didn't know why.

"The paternity test is different from the blood relationship test. The previous DNA test results of the dead woman and the child are not mother-child relationship, but we have no way to prove that Chen Yan gave birth to a child... Wait... I'm a bit confused!" Lin Sihang shook his head " I have to sort it out."

Song Haozhe let out a muffled laugh, and continued, "The woman lying in the forensic room is Chen Hong. Although she has never given birth to a child, we cannot directly prove that it is Chen Yan's child, but Chen Hong and Chen Yan are related by blood. Use that Y to prove that the murderer and the murdered are related by blood, right?"

Several people were confused when they heard it, but Lin Sihang clapped his hands excitedly, "It's so fucking right!"

The case was gradually developing in a better direction. Lin Sihang immediately used the evidence extracted from the rope and Chen Hong's for appraisal. Two days later, Chen Yan was summoned to the bureau as the first suspect.

"Let's go to the interrogation with Xiaobai!" Fang Bo said.

Compared with the first time she came to the bureau, Chen Yan looked much better. Lin Sihang and the others looked in through the glass outside the interrogation room. Chen Yan seemed to have put on makeup before coming.

"Do you have a good relationship with your sister?" Fang Bo asked, while Sun Shaoshi was typing on the computer and making interrogation records.

Chen Yan chuckled, "Officer, you seem to have made a mistake... I am Chen Hong, and I am my sister."

Fang Bo did not refute, and continued to ask, "How is your relationship with your husband?"

"Officer, what do you want to ask, just ask!" Chen Yan took out a cigarette from his pocket, "Can I smoke?"

Fang Bo nodded and looked at Chen Yan without speaking.

Chen Yan took a few puffs before asking, "You didn't bring me here to watch me smoke, did you? I'm going to see my mother off in the afternoon... Hurry up."

"Why kill people?" Fang Bo went straight to the point.

"What?" Chen Yan asked in surprise, but the hand holding the cigarette was shaking slightly.

"You should have been mentally prepared for a long time, right? It should be said to be a psychological hint..." Fang Bo slowed down his speech, and couldn't hear the tone. "You came to report the case for the first time, and you actually wanted to mislead the police and make us think that you are Chen Hong. You two are twins. You want to use this to clear yourself of suspicion... But you know what? You just showed your feet .”

Chen Hong put out the cigarette, took a deep breath, and instead of being flustered just now, she was full of carefree, "Is there any evidence?"

"Why kill?" Fang Bo continued to ask.

"This Fang Bo has two brushes...how do you say it?" Lin Sihang touched his chin with his fingers, "...break through the enemy's psychological defense line?"

"Are you fighting?" Song Haozhe took advantage of Yang Yizong and the others not paying attention, and squeezed Lin Sihang's fingers, "Why go after the case is over?"

"Hey, hey... Captain Song, why are you still working on the case!" Lin Sihang said in a low voice.

Song Haozhe quietly took his hand, and continued to stare.

Chen Yan's face began to show some impatience, sweat began to ooze from his forehead, and he began to look around uncomfortably. Fang Bo then took out a piece of paper from the folder and put it in front of Chen Yan. "I think the child should be the most innocent? It's your own."

"What is this? Chen Yan picked up the paper in front of her, it was a call record.

"Did you answer the phone when you entered the park? You shouldn't be able to remember such a long time...but that day..." Fang Bo didn't say anything later, and Chen Yan's expression became obviously flustered.

"Collapsed!" Lin Sihang clapped his hands.

"Keep watching!" Song Haozhe said helplessly.

"The owner of this call record is you, Chen Yan!" Fang Bo said firmly, while Sun Shaoshi's fingers were typing on the computer keyboard quickly.

"I said it...! I'm Chen Hong" Chen Yan's voice began to tremble a little, and she was a little unsteady when she spoke.

"Who are you, you know yourself." Fang Bo sighed, perhaps because he regretted the farce, "The rope you used to kill someone was found to have your human skin tissue on it, and the call records, including visits and investigations, are now all pointing at you."

"No!" Chen Yan suddenly retorted loudly, "Don't talk about these superficial evidence, I believe you have also done a paternity test, and that child has nothing to do with Chen Hong!"

"That's right, it has nothing to do with Chen Hong...it has something to do with you, Chen Yan!" Fang Bo nodded.

"What?" Chen Yan was stunned for a second, and immediately realized that she had said something wrong, and she collapsed on the stool in a somewhat dejected manner.

"It's my turn!" Lin Sihang saw that the interrogation was about the same, pushed the door and walked in, without giving Chen Yan time to react, he handed over a piece of paper.

"Where's the person?" Song Haozhe turned his head and asked Yang Yizong who was beside him.

"It's coming soon."

"Although there is no way to identify which of the two of you is Chen Hong and who is Chen Yan." Lin Sihang leaned on the table and said firmly with his arms folded, "but this case is not mainly about this point. The evidence, through the genetic markers of the Y chromosome, can determine that you are related to the female deceased, how many people are there in your family, our investigation and visits have a thorough understanding...so...Chen Yan, plead guilty! "

Chen Yan bowed her head and did not speak. Time passed by every minute and every second. Slowly, she took out her cigarette and took a trembling puff.

Lin Sihang sighed, looked outside, and saw nothing in the darkness, but he knew that Song Haozhe who was outside understood what it meant, and after a minute, the door was slowly pushed open.

Everyone in the room looked out, and an elderly aunt stood there with tears streaming down her face, "Yanyan!"

"Even if we can't tell each other apart, my mother won't be able to tell her child apart. Are you left-handed?" Fang Bo continued to interrogate regretfully.

Chen Yan in front of her had already calmed down, no longer flustered or anxious, she lowered her head as if giving up, and after a long while, she slowly laughed out loud. "I'm the only one who's an idiot in the end."

The atmosphere in the interrogation room was not as expected. After the murderer was found, the atmosphere should have been relaxed, but it was indescribably heavy.

Chen Yan said slowly, "Wang Yi and I met 7 years ago. It's ironic to say that the man has a successful career and is also a good-looking talent. Soon we two began to fall in love. I introduced him to my sister. The three of us often go out together, I thought it would always be so dull." Chen Yan smiled wryly, and tears began to fill her eyes, "I found out that I was pregnant after dating Wang Yi for a year, and I was going to propose marriage to him...who I know, I accidentally found out that he and my sister are still having an affair."

Lin Sihang took out two crumpled toilet papers from his pocket and handed them over. Chen Yan took them and continued with a blank stare, "I'm going to turn a blind eye, thinking that Wang Yi is trying to be fresh, but who will I know, when the child was three months old, Chen Hong told me that they were going to get married! What a big joke! She is my own sister, and she fucking robbed me of a man!" Chen Yan became emotional, and the toilet paper was ruthlessly beaten by her. I squeezed it hard in my hand, and the knuckles were a little green. "The children said they would take them with them to raise them after they were born. I gradually started to get in touch with drugs. After the children were born, I didn't have much contact with them."

"What made you want to kill someone?" Fang Bo continued to ask.

Chen Yan shook her head, and said as if comforting herself, "No... I didn't intend to kill anyone! They forced me!"

"Be specific!"

Chen Yan was not talking, she seemed to be thinking about something, after coming for a long time, she said in a desperate manner, "For so many years, I have never forgotten Wang Yi. Not long ago, I discovered his secret when I was at work. 7 years, 7 years! I have loved the man for 7 years, and even wronged the man who gave birth to him and gave him to my sister, but I actually like a man, so my 7 years have been bullshit to him !"
