"What do you mean by this?" I think what I said is very clear, but Chen Fang still doesn't understand.

"If it is said that the DNA of the murderer's bloodstains at the scene and the DNA on the cigarette butt match, that is, the cigarette butt was left by the murderer! That proves that he is a smoker! ”

"Got it!" Chen Fang suddenly realized.

"And from the DNA, it may be possible to identify that his last pair of chromosomes is XX or XY, and from this, it can also be identified whether his sex is male or female.

"Clever!" Chen Fang raised the corners of his mouth and laughed.

Judging from the way he smiled, it seemed that the worry in his heart had been put down a lot.

I'm so relieved!

After leaving here, as soon as I came to my office, I saw Ni Jiaxin running over in a hurry! She was so fast that she was running in front of me in no time.

"What? In such a hurry? I asked.

She pulled the chair next to her and sat directly next to me, "Officer Lu, let me tell you, I seem to have been followed just now!" As she spoke, she rolled up her sleeves and showed me.

"What's wrong?" As I spoke, I saw a scar on her hand. It looks like it's been scratched by wire!

"What's going on?" I asked.

She swallowed a mouthful of saliva, and then said tremblingly: "I was driving to the forensic examination center just now, and the car burst a tire halfway through!" I got out of the car, and someone came out of the side and snatched the cigarette butt I had in my pocket! When I went to chase it, my hand was hooked by wire! It hurts to death! ”

As she spoke, she looked at the wind blowing in her wound from time to time.

"So you didn't send that cigarette butt to the forensic center?" I asked.

"Yes! They were all robbed! As she spoke, she looked angry, "Hey, why don't you care about me?" Only care about one cigarette butt! ”

"That's evidence!" I was a little angry, but I held back, "Alas, forget it, I won't tell you!" ”

At this time, I was distraught, and I didn't want to blame her, so I chose to remain silent.

In the evening, after work, I waited for the bus alone.

I can't imagine that a car seems to be out of control, like I drove over! I was fast and took a sharp step back. The car swept right in front of me and almost killed me!

I looked at the license plate, but found that it had been covered by the owner with an army green cloth!

"Officer Lu!"

This sound scared me!

I immediately turned around and saw that it was Ni Jiaxin.

I frowned and looked at her dissatisfied, a little angry!

She noticed that I was in a bad mood and immediately asked me, "Officer Lu, what's wrong with you?" ”

"It's fine!" After saying that, I immediately raised my head and looked at the surveillance camera over there! I hurriedly turned around and walked back to the police station.

Ni Jiaxin followed me in!

As soon as the two of us came in, I said to my colleague, "Please help me retrieve the surveillance camera recording!" The one in front of the police station! ”

After my colleague pulled it out, I saw the car coming by, and through the windshield, it seemed that I could see the person's face, so I said, "Stop!" Rewind two seconds and zoom in! ”

The moment of being magnified is very blurry!

At this moment, Chen Fang was also going home from work. Seeing that I was still busy here, he walked over, put his hand on my shoulder, and asked, "Old Lu, what's wrong?" ”

I glanced back at him and said solemnly, "I was in front of the police station just now, and I was almost hit by this car. I suspect that this car owner has something to do with the case I'm investigating! ”

Chen Fang immediately said: "Put the whole video once!" ”

"Hmm!" The officer replayed the video.

After reading it, Chen Fang shouted: "This is simply murder!" Can you read the license plate? ”

"I can't see clearly, it's covered!" The policeman said.

Chen Fang immediately made up his mind and said: "Use this surveillance camera to track the owner of this car!" ”

"Good!" After that, we called up almost the city's surveillance cameras, just to find the owner of the car! As a result, only one suspicious thing was found: this car seems to have set off from the section of the KTV!

Early the next morning, Chen Fang and I came to KTV in person and found the manager.

As soon as the manager saw us, he was very enthusiastic and asked the secretary to pour us coffee, and all questions were answered! But for this car, his response was that he had not seen it either, and he could not help it.

Just as we were leaving, he chased after him and said, "Wait a minute, two officers, there's something I don't know if I should say or not!" ”

"What's the matter? You said! Chen Fang said.

He frowned, thought for a moment, and then said, "There is a very terrible strange thing, I don't know whether to tell you or not, because it may be related to my superstition!" ”

"It's okay, you say!" Chen Fang walked back slowly, and I followed suit.

After the manager led us to his office again, he lowered his voice and told us: "Actually, on the night of Zhao Jizhou's accident, I saw him sneaking around, as if he was talking to someone!" ”

"Where did you see that?" I asked.

"Security Booth!"

"And who was he talking to?" I asked.

"Nope! He was on his own at the time, so I thought it was weird! ”

Hearing what the manager said, I immediately turned around and looked at Chen Fang to see if he had any opinions.

Chen Fang was silent for a moment before asking, "Then did he wear headphones or something at that time?" ”

"Nope! I looked closely, and at first I thought he was talking to someone on the phone or something. Later, I found out that he was really talking to himself! What's even stranger is that when I drove away, he was still there talking to himself. ”

"Did you hear what he was talking about?" I asked.

The manager thought about it carefully and said, "He seems to say 'they are all so familiar' or something, and I don't know the rest!" ”

I couldn't help but turn my head and look at Chen Fang.

Chen Fang also happened to turn his head and look at me, and the look in his eyes had a sense of wisdom. It seems that he should be the same as I thought!

We are all thinking: Is the murderer related to Zhao Jizhou? Maybe it's an acquaintance!

After leaving, in the car, Chen Fang said to me: "It seems that I really thought too much before!" I thought it was some kind of ghostly thing, but it's nonsense! I think I'm ridiculous when I think about it! ”

"Alright, let's not talk about the previous things! Let's talk about what the manager said, right? I asked.

Chen Fang nodded and agreed: "Okay, you can talk about it, I'll listen!" After all, you know more about this case than I do so far! All I think about now is what we're going to eat for lunch! ”
