This night, Tang Guo didn't recklessly ask questions, just followed Qin Cang everywhere, the two of them walked to the park from the community where Kong Xiaotong and Li Yinliu's house were located, changed several inconspicuous benches around the park dance hall and sat down, silently watching the people in the dance hall dance, those people obviously did not have the slightest concept of the three consecutive murders that happened recently, the music was still melodious, the skirt was swaying, Qin Cang took Tang Guo to silently see these people disperse, and left one after another, waited until everyone was almost gone, then got up and left, but it was not to go back to the place where the car was parked, but walked directly towards the scene of the third murder, at this time, coupled with the increasingly cold weather, there were very few pedestrians on the road, and the two people walked quietly, and the footsteps sounded on the empty street, making the silence even more silent.

Tang Guo peeked at Qin Cang, Qin Cang was tightly wrapped in his windbreaker, and the collar was erected to resist the cold wind with obvious chill at night, she felt as if she was vaguely aware of Qin Cang's intentions, but she was a little uncertain, Qin Cang seemed to be seriously thinking about something, so Tang Guo kept all his questions in his heart, and did not open his mouth to ask questions, not wanting to disturb Qin Cang and disrupt his train of thought.

Walking to the mouth of the alley where the crime was found, Qin Cang stood there without saying a word for a while, and then turned around and walked back, Tang Guo hurriedly followed, Qin Cang was tall and had big steps, Tang Guo followed slowly and walked slowly, but he didn't feel cold, and when they returned to the outside of the community and returned to the car, Tang Guo walked out of a sweat.

"How? Any thoughts? Only then did she open her mouth to ask Qin Cang.

Qin Cang nodded, but did not answer this question directly, but turned his head to look at her, and asked rhetorically: "This night, you also followed me around, do you have any ideas now?" ”

"I did think about some questions, but I just didn't know if it was right." Although Tang Guo was not very accurate, after dealing with Qin Cang for a long time, she was not at all afraid to express her opinion in front of him, "Originally, I thought that the murderer should be someone from the community where Kong Xiaotong and Li Yinliu lived, at least from the vicinity of that community, there seems to be no doubt about this, otherwise it is difficult to explain why this person can get close to Kong Xiaotong and Li Yinliu at the same time." The murderer is obviously more familiar with Li Yinliu, so when he killed Li Yinliu, he also openly entered the house, as for Kong Xiaotong, the murderer probably knew her, but whether it can be regarded as an acquaintance, this is difficult to say, this may be because when he attacked Kong Xiaotong, the murderer was secretly black. I initially thought there might be some personal vendetta between the killer and the two female victims, but the presence of a third victim negated my idea. I tried to find the similarities between Li Yinliu and Kong Xiaotong again, but in addition to the fact that these two people are mothers and have children, they really can't find any similarities at all, and they are two different types of women, which are not related at all. Later the third victim appeared, and you said that the murderer could be in' Puzzle', I was inspired, I think it may really be what you said, between Li Yinliu and Kong Xiaotong, as far as the two of them are concerned, there is nothing in common at all, including the third victim, they are all the same, but their bodies have overlapping parts with the template in the murderer's mind, we didn't know what the murderer's template was like before, so naturally we couldn't find the similarities and differences, but the murderer's perspective is obviously different from ours. ”

She said so much in one breath, stopped and breathed a sigh of relief, looked at Qin Cang's reaction again, and saw that Qin Cang did not show impatience or disgust, so she quietly breathed a sigh of relief and continued: "So then I thought that the murderer may be more familiar with Li Yinliu, and he is relatively less familiar with Kong Xiaotong, but for Li Yinliu, the murderer seems to hate more than love, and Kong Xiaotong is just the opposite, which may also explain some problems." For example, the template in the murderer's mind, as a template of reference objects has some characteristics, some are liked, appreciated, loved, and some are hated, and each victim is a projection of a certain trait on the template object, so the murderer will have a sense of differentiation towards them. The appearance of the third victim has expanded the age range of the victim a lot, from another point of view, the third victim can be included in his 'puzzle' by the murderer, does this also show that the 'template' age in the murderer's mind will only be older than Liu Ying who appeared as the third victim, not younger than Liu Ying, right? ”

"That's right," Qin Cang was still quite satisfied with the answer given by Tang Guo, "Combined with all the details you said, have you sketched out an image in your mind now?" ”

"Yes, but I don't think there is any direct evidence to prove, so I'm still a little uncertain." Tang Guo nodded honestly, "It's not easy to collect evidence in this matter, after all, the murderer is very cunning from beginning to end, and he has never been photographed once." Before Liu Ying was killed, the nearby surveillance video was also screened, and no one was seen following her, it is obvious that the murderer already knows Liu Ying's daily action route well, it is estimated that he was ambushed in the nearby monitoring blind spot early, and he deliberately avoided the location with monitoring when he left, and he definitely went through a strict step and plan in advance! No matter how much we speculate and analyze, if we can't grasp the key things, and we can't find enough evidence to convict, isn't it all in vain? It gives me a headache just thinking about it. ”

"Liu Ying found the rose on the scene and extracted bloodstains." Qin Cang reminded Tang Guo.

Tang Guo shook his head: "But that's not enough, although this is a very important gain, but we have no reason, there is no other reason, how can we ask the suspect to take a blood sample for examination?" ”

"It's okay, let's just create opportunities." Qin Cang smiled slightly, looking confident, "Aren't those people in the team usually favorite to have a meeting, this time the opportunity is here, let's go here today, and as soon as we go to work tomorrow morning, let's have a meeting with them." ”
