Chapter 313

When Qi Jinnan heard the middle-aged woman's reply, she said to her patiently: "as long as you think something is abnormal or should not appear here, can you talk about it?" Qi Jinnan knows that it is obviously too late to investigate the toilet. In general, toilets in public places are cleaned up by special cleaners. Garbage is also cleaned up every day. There is a lot of liquidity here, so she also knows that there is nothing to investigate.

"Ah, say so! It's really a needle, isn't it? And a wig... " After the middle-aged woman said something, she seemed to think of something and said: "you say these two things are not available for going to the toilet. You say who is sick and doesn't go to the clinic for injection, and the wig, which seems to be used by a bald man, is lost here..."

"Auntie, can you still find these two important things? Has it been thrown away? " Qi Jinnan secretly regrets that she missed the first scene of the crime. It can be seen that she must have been following Jia Zhixu, so she injected Jia Zhixu with drugs in the bathroom.

"Where can I find the needle? I've already thrown it away, but the wig should be at the service desk. As soon as we find something from the customer, it will be delivered to the service desk. However, if the owner comes to find it, we will return it to the customer." Cleaning aunt said, looking at Qi Jinnan said: "this is a suspicious thing?"

"Auntie, I'm not sure, but can you take me to the service desk and get my wig? This thing may help me solve the case. " Qi Jinnan felt that the wig must have something to do with jiazhixu's case, so she went to the service desk with aunt cleaning and took the wig back.

When Hanyu comes out in the morning and doesn't see Qi Jinnan, there is a flash of urgency in her eyes. She looks around in a hurry. When she calls Qi Jinnan, she asks for her position and then rushes to her side. Looking at her wig, she can't help worrying and asks: "are you ok! Why didn't you wait for me? I thought something happened to you

"Where can I go? This is what the aunt found in the bathroom where Jia Zhixu went on the day of the crime. I suspect that she was following Jia Zhixu on that day, and the aunt also said that there was a needle at that time, but it was not that the needle had been thrown away. Let's see if we can find it back! What about you, have you found anything? "

"No, it's clean inside. It won't leave any trace after so many days." Han Yuchen shook his head, then looked at the wig in her hand and said, "it's not for nothing. Maybe you can extract something useful from this wig."

"Well, I hope so." Qi Jinnan nods, thanks the cleaner, and walks to the Criminal Police Brigade with Han Yuchen. Not long after Han Yuchen drives back to the team, Qi Jinnan directly throws the wig to the laboratory for examination, and then contacts Ye Yufeng to see if he can send some people to find the needle tube.

After hearing this, ye Xinfeng had a headache and said to Qi Jinnan, "Jinnan, I don't report any hope. Do you know where all the rubbish has been sent? It's a big garbage dump. It's not one or two that can be found there. It's mountains and seas of garbage. There's no difference between looking for needles there and looking for needles in the sea. "

"Do you have any other direction of investigation now? If we find the needle without any fingerprints on it, we can prove that the poison was not injected by Jia Zhixu himself, but was injected by someone else. If we have Jia Zhixu's fingerprints, we can say that it was injected by Jia Zhixu himself, which is a strong evidence to solve our conjecture, and since the murderer, We didn't take away the wig and burn it. It can be seen that the murderer doesn't have the knowledge of criminal investigation, so we may be able to extract the murderer's fingerprints on this needle. Do you think this needle tube is useful or not? "

"Come on, grandma, can't I get it? Isn't it just a needle in the garbage mountain? What's the difficulty? I don't believe it. Wait! I'll take the people of the city to look for it Ye Yufeng heard Qi Jinnan say, where do not understand the role of this needle.

"Oh, no, Jinnan's needle has gone through many people. Even if he found the fingerprints on it, I don't think they have been there for a long time! What other useful things can be extracted! " Ye Yufeng was just about to hang up the phone. In a flash, it was wrong. Where can the needle tube for injecting drugs be preserved completely? Even if it is found, it is extracted from anything.

"Don't worry, I asked that aunt. She rolled up the needle tube directly, wrapped it and threw it away. So the only problem we faced was whether we could find it. If we could, everything would be OK. If we couldn't, it would be in vain." Qi Jinnan also sighed, and then said: "you go to investigate and see where the garbage is sent. I will go there as soon as possible. Let's work hard all the time."

"OK, you don't have to. The place stinks. How can you stand it? I'll take someone with me!" After ye Yufeng hung up the phone, he reported the matter to his superiors, and directly took people to investigate.

Fortunately, the garbage has not been disposed of, and the garbage in recent days has been put separately. It's not so terrible, but the domestic garbage for several days is quite spectacular. Far away from laoyuan, you can still smell the stench. Ye Yufeng looked at it, and his first thought was that he would not be able to touch his wife for several days, otherwise his wife would be fumigated.

Qi Jinnan also changed her work clothes, wrapped her whole body tightly, put on her protective gloves, and then went to the garbage dump in the north of the city with Han Yuchen. She saw about ten people searching around a pile of garbage one by one. She saw ten other people around the pile of garbage. Behind them, there were small piles of garbage, Obviously it's been searched.

"Oh, hello... What is this? I'm lucky to be able to pick up money by picking up rubbish." A little policeman took out a folded one hundred yuan from the garbage heap, and the expression made everyone laugh.

Although everyone was dirty and smelly, there was no complaint in this environment. Everyone was looking for it carefully. She didn't waste her time and squatted down to find it with others.

In the morning, Han Yu was next to Qi Jinnan, and their movements were very fast. He held a small knife in his hand, cut the garbage bag directly, and then spread it with his hand. When he didn't find anything, he rowed to his side.
