"That's exactly what you said." Lin Ying looked at him and said.

"Captain Lin, you are a superior, you can get a bowl of water, although I am young, but I will never be sloppy in doing things, one is one, two is two, facts are facts, you can't say that her logic is wrong, facts are not facts, right?"

I was a little angry when I heard it, but after thinking about it, I put up with it.

"Alright." Shi Chong slapped Ju Xincheng from behind, "I didn't accept it before, but in the end, I was pulled back by Mr. Shen." ”

"Then you let her pull it, we are not unreasonable people, where do you see her all gone? Isn't this fountain the scene of a crime? She walked along the lawn and walked to the gate of the community! I think she is talking in the front, and now she can't make up for it, so I want to go home! "The more Ju Xincheng talks, the more angry he gets, but he makes me angry.

"How do you speak? Where she goes, what's your business? Didn't Lu Xianheng come in from the gate of the community that night? You know Locard's theorem, right? You know the on-site material exchange, right? If Lu Xianheng had passed by the gate of the community that day, how could you assert that there were no personal traces? ”

"Also Locard's theorem? I graduated from a prestigious university with a degree in forensic medicine! You're still talking to me about Locard's theorem! Who are you and what do you do? You wouldn't be like that Mr. Shen, a pheasant detective, would you? "Ju Xincheng began to talk to me and start a fire.

"What? Pheasant Detective? You say I can, but she can't! When I heard him insult Shen Yu, I immediately became angry.

Shi Chong, this guy was about to quarrel when he saw that the two of us were about to quarrel, so he quickly pulled away from the two of us and the mud: "Teacher Yan, Xiaoju, what's the use of you two arguing for a long time?" Anyway, when Teacher Shen comes back and speaks in a while, won't the matter be clear? Right? ”

"I'm too lazy to tell you." I saw Lin Ying and Shen Yu standing at the gate from a distance, as if they were inquiring about something with the people around them, so they left the "battlefield" and hurriedly walked over there.

Shen Yu was talking to a man carrying a broom and a dustpan.

"That is, there have been before, right? On the contrary, it didn't appear that day? She asked.

I stood silently between her and Lin Ying, Lin Ying looked at me and whispered, "This is the cleaner of the community, Yao Wansan." ”

Yao Wansan's expression was a little panicked, his feet kept changing positions, and I remembered that when Xu Chuyue told about the ghost of flowers, she said that the person who found Lu Xianheng's body was called Yao Cripple, and he was a cleaner, so it seemed that this person was undoubtedly this person.

"Yes, yes, I wake up early every day to clean the community, and I care a lot about these dirt. There are tens of thousands of people living in this community, and everyone thinks that it is okay to throw away a little garbage and damage some public facilities casually, but the cleaners in the community can only be a few people. A few people serve 10,000 people, how can they not pay attention to this, after all, there is more garbage on the ground, I have to do a little more work, right? ”

I couldn't help but nod. Yao Wansan is really right, everyone thinks that throwing away a little garbage is nothing, but for cleaners, it is a tower of sand.

But I came late, and I really didn't know what Shen Yu was asking, so I asked Lin Ying quietly.

Lin Ying whispered to me: "She was asking Yao Wansan if he had used a water hose to water the lawn recently, and Yao said that the lawn was sprinkler irrigated and no one needed to water it." She asked again where the stains on the lawn came from, Yao Wansan said that she didn't know, but remembered that they appeared a long time ago and some days in a row, but the stains did not come out before the day of Lu Xianheng's accident, and they never appeared again. ”

"Stains, what stains? around the pool? ”

"There is no around the pool, there is a lawn, you can't find it if you don't look carefully, even if you can find it, you said that the grass originally grew on the side of the road, and people and cars came and went next to it, and it was gray and dirty every day, and there must be some dirty traces, and normal people wouldn't care."

"Can I go check it out?" I asked.

"Ah, it's over there." Lin Ying pointed to an area on the lawn not far away and said, "It's strip-shaped, or intermittent, if you have good eyesight, look for it." ”

I ran to that lawn. The community is covered with rye grass and tall fescue, probably not carefully trimmed for a long time, so the grass grows unevenly, and when you stand and look at the already flowery patch, you can't see any dirt at all.

I had to squat on the ground and pick at the soil underneath the grass, which was dry and a little clumpy, and looked like it hadn't been watered for a long time.

It hasn't been repaired for a long time, it hasn't been watered for a long time, and Shen Yu may have discovered this problem. The lawn is the shortest shortcut and necessary way from the gate to the fountain - if you don't want to take the main road, just follow a broken stone path on the lawn to get from the gate to the fountain.

So I think the place where Shen Yu found the traces should be near the stone road.

I walked to the lawn near the stone path, which was about half a step apart as it was only a landscape path. At this half-step interval there were two kinds of grass that were mixed and sown.

I knelt down on one knee and looked at the dust and dirt on the grass, and soon found what Shen Yu called "traces".

Those "marks" were all on the blades of grass, and although they were strips on a large scale, they were patches of dirt when viewed closely, and the color and texture of these dirts were completely different from other dust and mud stains, and they looked a little dark green, as if they had been dyed.

I twisted the dirt with my fingers and put it in front of my nose, but I didn't smell anything.

I stood up and walked back to the gate. Shen Yu was still chatting with Yao Wansan, when a man in a suit walked over briskly with another boy who was half the size of a small man.

"Hello! Are you Captain Lin? He walked up to Lin Ying and said hello.

"It's Manager Shang, right?" Lin Ying nodded and asked him.

"Yes, I am Shang Jianchun of Xinyunli Property."

"I want to ask, are there no guards and security guards on duty at the gate of our community?" Lin Ying asked.

"It's not long since the community first got up, and most of the people who live in it are the villagers of Yuntang Town, and the personnel are relatively single, so there is no arrangement." Shang Jianchun explained.

"The surveillance is not safe either."

"Yes, it's all folks-Na Cheng thought that there would be an accident later, and we just added a monitoring system, which will be installed in two days. We also bought the sentry box, which can be installed this week, and the security guards are also in place.

"I've inquired for you, there are people who throw away green sheets on the old street, but they don't care, it's the old sheets, sometimes they are blown away by the wind when they are hanging outside, and sometimes they are mischievous by the children, which is normal, and they don't think much about it."
