When Song Yang heard what Huang Xiaotao said, he was stunned for a moment.
She quickly said on the phone, "Forensic Doctor Qin went to Deng Chao's dorm this morning and collected his hair and skin flakes from his personal belongings. After comparing the DNA with the deceased's, guess what?"
"The DNA matched?" I asked.
"Yes! Our previous deductions were all wrong. Deng Chao is already dead, and the murderer is someone else... Hey, Song Yang, are you listening?"
"I'm listening!" I said.
"Don't be discouraged. I have confidence in you. Let's reinvestigate. I'll come to school right away." After saying that, she hung up. Wang Dali also heard it and said in surprise, "Bro Yang, how could you get it wrong? Then all our hard work before was in vain?"
To be honest, when I heard the news, I was also a little shaken, but soon calmed down again: "I didn't get it wrong."
Wang Dali said, "Are you unable to accept this blow? DNA cannot be wrong. There are no two people in the world with the same DNA. I know you really trust your ancestors' methods, but don't get mad at me for saying this - how can witchcraft compare to forensic science? They have mastered advanced technology."
I smiled faintly: "I don't deny that forensic scientists are very capable, but people like Forensic Doctor Qin should be avoided! I'm not panicking now, on the contrary, I'm more confident, because Forensic Doctor Qin has already fallen into the pit."
"Yang Zi..." Wang Dali wanted to say something more.
I interrupted Wang Dali: "That's enough, go and buy some things for me."
"What about you?" Wang Dali asked.
"Going back to the dorm to sleep for a while. I'm going to stay up late tonight." I said.
I went back to the dorm and slept for a while before being woken up by the loud banging on my bed. When I opened my eyes, I saw Huang Xiaotao with Wang Dali. Because of her intrusion, the other people in the dorm were very nervous.
Huang Xiaotao frowned and said, "Song Yang, get up quickly. We haven't lost confidence in you, so how can you give up on yourself at this critical juncture?"
I was amused: "How did I give up on myself?"
"Wang Dali said you went back to the dorm to sleep. Isn't this giving up? We're already behind Forensic Doctor Qin. We need to work harder," Huang Xiaotao said anxiously.
"Sigh!" I sighed, "Go away for a moment. I need to get dressed."
After getting dressed, we went out of the dorm. Seeing them looking worried, I knew they still thought I was wrong if I didn't explain it clearly to them.
"You said we're behind Forensic Doctor Qin, but actually, he's far behind us and has fallen deep into the pit. I don't think he can climb out," I said.
They looked at me blankly. Wang Dali asked first, "How could there be Ma Baobao's skin flakes and hair in Deng Chao's dorm?"
"There's only one answer. Deng Chao scattered these things on his personal belongings beforehand, preparing a trap for the police. He's an extremely intelligent criminal. It's normal for him to come up with such a trick." I said.
"No!" Huang Xiaotao interrupted me, "Although it can be explained this way, these are all your conjectures. You can't deny it's more likely the DNA came from Deng Chao."
"There's no such possibility at all!" I said.
"How can you prove it?" Huang Xiaotao asked.
I smiled, "You really asked the right question."
I showed them Deng Chao's phone purchase list. The last item was a razor.
"The reason Deng Chao bought a razor was to scrape skin flakes and hair from Ma Baobao's corpse," I said.
Wang Dali said in puzzlement, "Isn't this going overboard? Which guy doesn't have a razor? Why buy one specially?"
I was exasperated: "His own razor would have his own skin flakes on it! He must have disposed of it long ago!"
Huang Xiaotao's expression gradually improved: "You analyzed it perfectly. That's exactly right. I bumped into Forensic Doctor Qin at the bureau just now, and he was still smug about it. Now it looks like the old fool has completely fallen into the pit. Let him slowly crawl out."
"So I said we're ahead of him, not the other way around!" I smiled slightly.
Wang Dali exclaimed, "My god, Deng Chao really lives up to being a top student. He's daring and meticulous, even considering such small details..."
"This is no small detail. It's an important step for him to slip away! Tricking two girls is useless. The key is to deceive the police. If the police had investigated normally, they would have been completely led into his trap." I said.
Huang Xiaotao suddenly said, "Song Yang, I suddenly feel you're so scary. The criminal's mind is meticulous and different from ordinary people, yet you can follow his every step closely! If you used your genius mind for crime, the police would definitely be driven crazy."
"Don't worry, I will never commit a crime." I smiled slightly.
"Humph, I don't care. I'm going to keep a close eye on you and make your brain serve me and earn credit for me. Of course I won't skimp on your bonus." Huang Xiaotao humphed loudly.
"Okay, okay, from now on I'll be your consultant." Speaking of razors, I suddenly remembered something and asked Huang Xiaotao, "Right, this morning I asked you to dredge the artificial lake. Did you get anything?"
"I don't have any authority now. Not to mention mobilizing people, Squad Leader Lin might even punish me if he finds out I took action on my own," Huang Xiaotao said helplessly.
"Never mind, it's not too late to dredge it later," I sighed.
"Are Deng Chao's murder weapons in the artificial lake?" Huang Xiaotao asked.
"There's a high possibility. Anyway, these things will become key physical evidence to convict him of murder in the future," I said.
"Right, you previously said you wanted to lure Deng Chao out. Any results?" Huang Xiaotao continued to ask.
"Of course!"
I recounted how Deng Chao had contacted me through Weibo and talked about my plan. I planned to go to Music Classroom 4 alone tonight. Of course I wouldn't really be alone. Huang Xiaotao and Wang Dali would be lying in ambush. When Deng Chao showed up, we'd catch him!
When I mentioned going to Music Classroom 4, Wang Dali started panicking again. Huang Xiaotao threatened that if he didn't go, he wouldn't get a share of investigating cases in the future. Only then did Wang Dali reluctantly agree.
I asked Huang Xiaotao, "Right, did you investigate the piano corpse case from ten years ago that I asked you to look into?"
"I did. The murderer's name is Cao Bufan, and the girl's name is Xia Mo," Huang Xiaotao replied.
I muttered the names and nodded: "Thanks."
"Why did you ask me to investigate this? It's unrelated to this case." Huang Xiaotao wondered.
"It's unrelated, but just in case we meet Xia Mo's ghost tonight, not even knowing her name would be too rude," I laughed.
"Whaaaaat!" Wang Dali was so frightened his face turned pale. "You're even planning to meet that female ghost. I won't go, I won't go, you can beat me to death and I still won't go!"
Huang Xiaotao frowned, suddenly pulled out her gun and pointed it at Wang Dali's head: "You said it yourself I could beat you to death!"
Although I knew she wouldn't fire, with a real gun pointed at his head, the timid Wang Dali immediately caved in: "Sister Xiaotao, I'll go, I'll go, isn't that okay? Hurry and put the gun away, it'd be bad if it went off accidentally."
"It won't go off. The safety is still on," Huang Xiaotao said as she put the gun away. Then she pretended pompously, "Oh no, turns out the safety was off. I'm really sorry."
Wang Dali was immediately so scared his legs went weak. If I hadn't held him up, he would have collapsed to the ground.
