sin of heart

"You don't have to worry about that!" Chen Liuli frowned, "You can answer whatever I ask you."

Wang Ping looked a little scared, Fang Ge couldn't help but said softly: "Uncle Wang, don't be afraid, it's not a big deal."

Wang Ping laughed dryly, but you look uglier than crying!

Fang Ge was speechless, secretly wondering when the image of the Huaxia police in the hearts of ordinary people will be reversed!

No matter what Fang Ge was thinking, Chen Liuli had already started to ask: "When did Song Zhi move here? Did he move here alone or with two people?"

"I remember... about a month ago..." Although he was very scared, Wang Ping still tried to remember.

After some inquiries, Fang Ge roughly understood what happened.

It is true that Song Zhi moved here a month ago, but at that time he lived here alone. After a while, a young woman suspected of Gu Fangfang moved in, but it didn't take long for Gu Fangfang to reappear. Pass.Although the relationship between Wang Ping and Song Zhi was pretty good, they were not familiar enough to ask about everything, so Wang Ping didn't ask too many questions.

"...Well, isn't Song Zhi usually at home at this time?" Chen Liuli, who was recording while asking, asked.

"No!" Wang Ping said, "Lao Song is very diligent. Apart from his habit of doing morning exercises in the morning, he usually goes shopping for vegetables and comes back to cook at regular intervals. It's almost 11 o'clock now, so he should have been shopping for vegetables long ago! "

"Should have come back a long time ago?" Chen Liuli repeated, her brows frowning into a Sichuan character.

Fang Ge also had a bad feeling in his heart. If what Wang Ping said was correct, then Song Zhi should be cooking at home at this time, but just now he and Chen Liuli knocked on the door for a long time and no one responded, could it be This Song Zhi escaped?

"No!" As if guessing what Fang Ge was thinking, Chen Liuli shook her head and said, "After I found Song Zhi's trace, I found someone to watch it. Song Zhi can't leave quietly!"

"Then..." Fang Ge felt even worse: "He won't..."

"I remembered!" Just as Chen Liuli was about to break the door violently, Wang Ping suddenly slapped his forehead and said, "The past two days, Lao Song has always been talking, and he usually doesn't stay at home, especially at night. He would rather stay in a fast food restaurant for a whole day! During the daytime, he would not come back until there are too many people! It’s not yet time for work and school, so he probably won’t come back in a while.”

Hearing what Wang Ping said, Fang Ge and Chen Liuli glanced at each other.

"There is a problem!" Fang Ge whispered.

"Nonsense! An idiot can see that something is wrong!" Chen Liuli stabbed Fang Ge, and then asked, "When did this situation start?"

"I'm not so sure about this." Wang Ping said with embarrassment on his face: "I don't always stare at him. There were several times when I was missing. When I came to look for Lao Song, I found that he was not at home, so I knew Yes. As for when he started doing this, I really don't know."

Chen Liuli nodded, took out a photo from her bag, and asked, "Is that the young girl you saw in the photo?"

Wang Ping stared at the photo for a long time before saying, "Well, it's her! Comrade policeman, who is this girl? What is the relationship between her and Lao Song?"

"Niece!" Chen Liuli put the photo away: "It's not a murder case, don't think about it!"

Wang Ping smiled embarrassedly: "I don't think so."

Chen Liuli snorted, didn't say any more, turned to look at Fang Ge: "Since Song Zhi is not at home, let's wait."

Fang Ge frowned: "Sister Liuli, show me the photo just now."

Chen Liuli was puzzled: "What are you looking at?"

Having said that, Chen Liuli still handed the photo to Fang Ge. Seeing that Wang Ping was still at the side, she said, "Thank you for your cooperation. If you think of other suspicious places, please contact us at any time. Go to the criminal police brigade and Can."

Wang Ping was startled for a moment, then said with a smile: "You're welcome, you're welcome, that... I'll go back first."

"Okay!" Chen Liuli finally showed a little smile.

After Wang Ping left, Chen Liuli realized that something was wrong with Fang Ge.

"What's wrong with you?" Chen Liuli asked strangely.

"I'm such a fucking idiot!" Fang Ge gritted his teeth: "Why didn't I think of it at first? This is simply an unforgivable mistake!"

Chen Liuli didn't understand even more: "I said what's wrong with you?"

"Sister Liuli, I may not be able to wait for Song Zhi with you!" Fang Ge said quickly: "I found a very important clue, and I must go to Brother Lei immediately."

Chen Liuli frowned: "Don't you know that you were pulled by me?"

Fang Ge is now full of Liu Qingming's case, and he has no intention of "waiting for a rabbit" here with Chen Liuli at all. He went downstairs and said, "I don't have time to explain so much, Sister Liuli, I'm sorry, I'll talk to you another day." I apologize to you again! By the way, I confiscated this photo!"

Chen Liuli stomped her feet angrily, and finally followed Fang Ge downstairs.

"Go! I'll take you back!" Chen Liuli said coldly.

"Huh?" Fang Ge looked at Chen Liuli puzzled, "You won't wait for Song Zhi?"

"Do I have any evidence?" Chen Liuli didn't give Fang Ge a good look at all: "No evidence, I'll wait for him to have a fart! I can't catch him! You're being bullshit, get in the car quickly! I don't have so much time to ink with you !"

Fang Ge shook his head and smiled, lowered his head and got into the car.

Q City Criminal Police Team, Lei Chi is interrogating Dan Tiantian.

"Tell me, where were you on the night of June 6th!" Lei Chi sat across from Shan Tiantian, looking at her expressionlessly.

Shan Tiantian frowned: "Officer, didn't I say that before? Mingda and I are together! We drank all night!"

"Then how do you explain that your blood will appear on the body of the deceased?" Lei Chi said with a gloomy face, "Haven't you and the deceased not seen each other for a long time?"

"That's right!" Shan Tiantian's reaction was great: "I still have to ask you! Why do you say it's my blood? I still say it's that bitch's blood!"

"Stop making excuses!" Lei Chi slapped the table violently: "Do you think us police are all idiots? The DNA comparison results are all out! What else can you say?"

Shan Tiantian was stunned for a moment, then loudly denied: "I don't know! But I really wasn't with Liu Qingming! I swear, I was with Mingda the night before yesterday! You...you don't even believe what I said , should you trust the monitoring and security of the community?"

Lei Chi was also very upset. This is the difficulty of this case. Whether it is Lu Mingda's testimony or the monitoring of the community, it is enough to prove that Shan Tiantian was indeed with Lu Mingda on the night of June 6, but if this is the case , Then why was the DNA of Shan Tiantian found in the blood stains extracted from the deceased?

"Bang bang bang..."

Just when Lei Chi was in a dilemma, a sound of knocking on the glass interrupted his thinking.

"Huh? Why did you come back so soon?" Seeing that Fang Ge was knocking on the glass, Lei Chi couldn't help muttering.

"Fang Ge, why do you..."

"Brother Lei, we were all wrong!" Fang Ge said seriously before Lei Chi finished speaking.

Hearing Fang Ge's words, Lei Chi's heart pounded and he fell to the ground.

"What's wrong?" Raichi asked.

Fang Ge didn't hold back, and handed Lei Chi the photo of Gu Fangfang that he got from Chen Liuli: "Look for yourself!"

"This...how is this possible!" Seeing the photo, Lei Chi was also stunned: "This is Shan Tiantian? Where did you get it?"

"What Dan Tiantian! That's Gu Fangfang!" Chen Liuli who just came in said, "That's the suspect in the case I'm investigating."

"Damn it!" Lei Chi couldn't help but swear: "What the hell is going on!"

Chen Liuli frowned: "What do you mean?"

"Junior Sister, you can see for yourself." Said Lei Chi moved away.

And Chen Liuli naturally saw Shan Tiantian in the interrogation room, and immediately exclaimed: "Gu Fangfang? So she's here! I've worked so hard to find her!"

"She's not Gu Fangfang!" Fang Ge said in a deep voice, "We all made a mistake!"

"That's right!" Lei Chi nodded: "Why didn't I think of that! Shan Tiantian and Gu Fangfang are probably twins!"

"That's right!" Fang Ge also nodded: "That makes sense. And I think that the woman in the folder that Shan Tiantian found out after arguing with Liu Qingming before is Gu Fangfang! But there is one more thing I don't agree with. Too clear, twins have the same DNA?"

"I have to ask my colleagues in the technical department!" Lei Chi said without delay, "Let's go! Let's go there now!"

"Then here..." Fang Ge pointed to the interrogation room.

"It's okay!" Lei Chi said, "48 hours is still a long time!"

……

"Twins?" Hearing Fang Ge's words, Sun Xinyue also showed an expression of disbelief: "Are you sure?"

"Look for yourself!" Fang Ge handed the photo to Sun Xinyue again: "Shan Tiantian, you should have seen it just now, the person in this photo is Gu Fangfang!"

"It's really twins!" Sun Xinyue said with emotion: "This can happen to me, so what should I say?"

"Doctor Sun, that's it. I want to ask if the DNA of identical twins is the same?" Fang Ge asked.

"Theoretically they are the same!" Sun Xinyue explained: "However, the influence of the acquired environment will also cause the DNA of twins to be no longer identical when they become adults, but the difference between them is very small, and DNA testing does not compare all DNA sequences. , just select a few specific sites, and the differences in the DNA profiles of twins are very small, so it is difficult to identify the differences between the DNA of identical twins with current technology."

"That's troublesome!" Fang Ge's face was ugly: "We can't be sure whether the DNA on those bloodstains came from Shan Tiantian or Gu Fangfang!"

Lei Chi also frowned: "The clues that were finally discovered are worthless again!"

"It would be great if the fingerprints can be extracted." Sun Xinyue couldn't help but said: "Although the DNA difference between identical twins is difficult to detect, but the fingerprints are different, everyone's fingerprints are unique! If a fingerprint is found at home, then it can be established who was with him that night."

"I'll send someone from the Trace Inspection Department to go to Liu Qingming's house right away!" Lei Chi said, "Liu Qingming's house is very messy, and fingerprints should be extracted."

"Okay, let's—"

In the middle of Fang Ge's words, Lei Chi's cell phone rang suddenly.

"What did you say?" Lei Chi lost his voice, "Did you find Shan Tiantian's body?"
