While we were eating delicious barbecue and drinking juice, Zheng Qi mentioned the case again: "The follow-up work is mainly to check the whereabouts of Tianyan and the deceased, as long as they are found to have been in contact with the same suspicious person, and after investigation, the identity of the suspect should be determined." ”

"Theoretically, yes, but don't you think anything will change after that?"

"It's hard to say, but I state in advance that I feel that the case is already very clueless, after all, we have found a lot of physical evidence."

I shook my head, and before I finished eating, my mobile phone was already ringing, and it was a message from the laboratory department: "Team He, the DNA results of the sweat stains came out, not from any of the deceased, and we combined the test of the half of the fingerprints and found that there was also the same set of DNA on it, which is likely to be from the murderer." ”

Seeing this information, my frowning brows for many days have eased a lot, it seems that this time everything is really ready only to owe the east wind, I showed Zheng Qi the information, she immediately made an OK gesture in front of me and then swallowed a mouthful of ribs before saying: "I just said, you don't have to worry, after all, this is reality, not fiction, how can there be so many flipping situations?" ”

I ignored Zheng Qi's claim that he seemed to be joking, I have always been cautious, and in many cases I have solved over the years, there have been many unexpected results, so I will not be so quick to draw conclusions until the last minute.

Although Zheng Qi has been in the Public Security Bureau for a longer time than me, it is not much longer, and she has led to the appearance of unsolved cases many times because she is not careful enough, but after I came, I slowly investigated these cases clearly.

Finding that I was thinking, Zheng Qi sighed: "My Detective He, I think it's good that you can let go of the past, just start with this case, as long as you solve it, you should come out, you know?" People don't want to see you still dwelling on the old days. ”

Of course I understand, don't say that Zheng Qi is Huang Ju often tells me about this matter, I didn't answer, I was silent, and when we finished eating, Zhang Meimei let me go.

When I came to the Graphic Investigation Technology Department, they had screened out the whereabouts of the victims before the accident, and found out the common denominators, but when I came to Zhang Meimei, she was still secretly looking at the list of dog food.

I deliberately stood behind her quietly, feeling something standing behind her, Zhang Meimei reacted, her whole body was like an electric shock, she trembled violently, and then she directly hugged the screen and said, "I haven't been watching it for long!" ”

"Don't be nervous, I'm curious, why do you often watch this, you don't have a lot of puppies at home, right?"

"No, sometimes I buy it and give it to the stray dogs."

"Well, do you spend all your wages on these things?"

"Hmm...... Partly, at least I don't have much savings a month other than this and dressing......"

Zhang Meimei's two fingers were touching left and right, and at the same time she looked aggrieved, but I pressed her mouse: "Didn't you say that you found an important clue?" ”

"Yes, you click on this file, it is all the information I have saved, you will know it at a glance."

I opened the file according to her prompts, and the appearance of several victims appeared near a mountain behind Swan Park at the same time, Zhang Meimei said: "Due to the limited coverage of the eye of the sky, we can't see the scene after they enter the mountain, but we gathered according to several time periods and their whereabouts, and found that they came to this place a bit densely, the key is that the victims also appeared here, and the time is concentrated on weekends, which makes people feel very suspicious, so I deleted some information, Sort out this part for you to see. ”

"It's hard work, this work should be very complicated, my eyes hurt lately."

"It's okay, there are a lot of people here to help me, but it's a little difficult to cut, I suggest that you go to this back mountain as soon as possible to search, and this swan park should have some connection with the murderer, otherwise how could he lock this place?"

Zhang Meimei was right, in fact, I had doubts about this before, I said: "Have you conducted a detailed investigation of Swan Park?" ”

"Checked, it was built in 2011, there are some years, it is said that it was once a very lively and popular tourist resort, but over the years the park has been built too much, and he has no reconstruction and planning here, and gradually the popularity has decreased a lot, oh yes, this swan park and the person in charge of the tourist area before the accident turned out to be the same person, his name is Wu Zhengqing, do you say this will be ......"

Before I finished speaking, my heart suddenly chuckled a few times, and at the same time became vigilant: "Zhang Meimei, now I will give you a task, go and investigate Wu Zhengqing!" ”

"Yes, I'll let the reconnaissance team assist me."

When I left the technical department, Zheng Qi and Liang Xiaohu came over, and they said that it was time to go to the back mountain of Swan Park, and I thought it would be better to deal with this matter as soon as possible, so I took some police officers and drove out of the public security bureau in three cars one after another.

Coming to Swan Park again because there was an accident here before, and now there are police cordons all around, according to this situation, even if Wu Zhengqing has nothing to do with the previous case, he must cooperate with our police to investigate, but now that we haven't found his person, we plan to go to the back mountain of this place first.

Everyone is equipped with individual police equipment, you must know that this neighborhood is likely to be the haunt of the murderer, otherwise those victims would not have been here so coincidentally before their deaths.

We went around the entrance of the back mountain from the side of Swan Park, and when we passed near the bell tower before, we saw the appearance of the complete collapse here, Zheng Qi and I felt a little like the rest of our lives, as if what happened yesterday was like a dream, and a good bell tower would be completely destroyed in that situation.

After we entered from the back mountain, everyone stepped on the muddy mountain road, and found a lot of footprints in some corners, although we don't know who they came from, but we all guessed that these footprints were probably left by the previous victims when they came here.

We followed these trails until we came to a mountainside in the back mountain, where we didn't expect a building that resembled a horror house like a playground.

Seeing this, Zheng Qi said: "This is the amusement equipment in Swan Park in the past, right?" But now it seems that this thing has been abandoned. ”
