"I've thought about it, but there's really no pattern to follow. The first was two years ago, the second was four months ago, the third was six days ago, and the fourth was last night. According to the forensic doctor's inference, the time of the crime was two days ago, that is, there was only a gap of three to four days between the third and fourth crimes. Yang Rui frowned tightly and said: "I personally think that this should be an inconsistency in the time of each encounter with the target, the suspect did not mean this, but as long as he encountered the opportunity to start, he did not hesitate to start, and there is no specific rule." ”

"I don't think so." Qiu Yu said with a solemn face: "The four deceased are not locals, and no one knows them in Jingcheng at all, which means that these four deceased were killed when they came to Jingcheng from other places. Since it has been established that the motive for the crime was revenge, and the four deceased were the targets of the suspects' revenge, the first and second may be barely explained as a chance encounter between the two parties in Jingcheng, but it would be too far-fetched to say that the third and fourth were still chance encounters. In my opinion, this possibility is almost the same as the odds of winning the jackpot in a lottery ticket. He paused, and then said: "Also, according to my previous speculation, since the suspect had coerced confessions before the killing, then he should have more or less grasped the information of several other deceased, if he was in a hurry to kill and take revenge, why didn't he immediately go to the second, or the third and the fourth, after killing the first." ”

"Then you mean that the suspect should have other purposes for doing this, but we don't know for the time being." Yang Rui said in disbelief.

Qiu Yu's eyebrows were about to be twisted together, and he said slowly: "I'm thinking, how could the suspect suddenly become so eager?" Also, why do you have to choose to kill people in Jingcheng? He thought for a while, and then said, "Could it be that this is a warning, or a provocation, or a hint?" ”

Hearing this, Yang Rui's brows furrowed even tighter, and he looked at Qiu Yu beside him, his eyes were a little complicated.

"Brother Qiu, didn't you discover the secret of this pattern yesterday, tell Brother Yang about it." Wang Bing glanced at Qiu Yu, and his face was actually a little excited.

"Really? So awesome? Yang Rui was a little surprised.

"It's just luck." Qiu Yu smiled bitterly, and repeated what he said to Wang Bing yesterday, but out of some considerations, he didn't tell the two that they had been to the temple together.

"So, the suspect should still believe in Buddhism? A Buddhist? Or even a monk? Yang Rui was simply surprised.

Qiu Yu shook his head and said slowly: "Not necessarily, what he did was really very different from the teachings of Buddhism. It seems to me that there may be only some understanding, or even only partial understanding. He paused, and then said: "Now there is only one way to go for the time being, and that is the group of people who believe in Buddhism in Jingcheng, especially Tibetan Buddhism." Of course, it is highly likely that the suspects are not these people, but among the people they are serving or knowing. ”

"Okay, then I'll go back to the unit first and arrange all the work." Yang Rui said with some excitement: "You take a look at those photos and materials first, and wait for me to come over." After speaking, he went out in a hurry.

"Damn, I only have the case in my eyes, and I don't care about my brother's life or death." As soon as Yang Rui went out, Wang Bing said extremely dissatisfied: "No matter what, you are also a guest, and you are still the best classmate and friend of the police academy back then." came to play, was made a suspect and didn't say anything, and was beaten and injured by the crowd, so I have to care about it, and now I don't even let out a fart, it's really inhumane. ”

Hearing this, Qiu Yu is simply a black line, it seems that once this woman's mind changes, it will be really difficult to adapt for a while. Before, everything was pleasing to the eye, but after the change, everything was not pleasing to the eye. In fact, in his opinion, Yang Rui, as a leader directly responsible for the case, these practices are extremely normal, and there is nothing wrong with them. Perhaps, there is a little snub about himself, but this should be a last resort.

"What you said is not right, he can't help it, the criminal police are like this, I can understand." Qiu Yu was really a little crying and laughing.

"That's not the case at all, I didn't even notice it before, and now it seems that he is really a little abnormal." Wang Bing said disapprerovingly: "I have known him for so many years, and since he became the captain of this brigade, there have been many serious cases than this, but I have never seen him work so hard." His mind is spent on his own business, business is the main thing, work is supplemented, and that kind of person is him. In my opinion, if he hadn't needed this status, he would probably have resigned a long time ago. ”

Wang Bing said that this situation is not uncommon among public officials, many of whom do business outside the home in the name of family or friends, for whom this meager salary is a drop in the bucket. The reason why I still want to keep this job is only because of business needs, not life needs. Hearing this, although Qiu Yu was a little surprised, he didn't pay too much attention to it.

Wang Bing thought for a while, and then said, "But then again, maybe he really cares about you." If it weren't for the fact that it was to help you clear up your grievances, you shouldn't be so desperate. ”

Qiu Yu nodded, and a warmth suddenly rose in his heart. Only then did I click on those bloody photos and look at them carefully. I was busy analyzing the case with Yang Rui just now, so I didn't have time to read these materials.

"This kind of stone pier is really not small, and the hands and feet of the deceased are fixed on it, and it is indeed difficult to move." Looking at the photos at the scene of the center, Qiu Yu said while looking at it: "With such a heavy thing, the suspect can actually move from outside the hospital to the interior alone, which shows that he is indeed very strong." ”

"The ligaments of this deceased man are very good, and the horse is really good." Wang Bing was next to Qiu Yu, staring at the screen of the computer, and actually made such a comment.

Qiu Yu frowned, staring at the photo that Wang Bing was talking about. In the photo, the hands and feet of the deceased are fixed to four stone piers on either side of the body, just like the ancient five horses divided into corpses. There was nothing strange about the stone piers with hands tied on either side of the body, but the stone piers with one foot tied to each foot were not under the body, but had been placed almost parallel to the buttocks, so that the corpse's legs were almost stretched in a line.

Qiu Yu kept looking at the photos related to this location, and after a long while, he said with a solemn face: "It seems that my previous speculation was correct, and the suspect was indeed coercing a confession." ”

"How do you tell?" Wang Bing looked puzzled.

Qiu Yu enlarged one of the photos, pointed to the computer screen, and said, "The stone pier that fixed the feet should have been placed under the body at first, parallel to the deceased's calf. At that time, the legs of the deceased were normally separated, that is, although the deceased was immobilized, the body was not uncomfortable. Notice that there are scratches on the ground caused by the movement of stone piers and the friction of the ground. This kind of trace, starting from the position I just mentioned, slowly moving up to the current position in a trajectory like a compass drawing. Not only was the movement slow, but there were many pauses in between. ”

Wang Bing stared at it carefully, and found two very fine ribbon scratches on the concrete floor next to the corpse. The scratches were indeed as Qiu Yu said, drawing an arc from the place where the corpse's feet were parallel to the calves to the position parallel to the corpse's buttocks, and the left and right sides were exactly the same.

"Yes, yes, yes, there are indeed traces of friction." Wang Bing's face was excited, and he said: "But I don't understand, why can you be sure that the movement is not only slow, but there have been many pauses in between." ”

"It's simple, don't you notice, these scratches are not only not smooth, but they are not continuous, they are intermittent."

Hearing this, Wang Bing stared at it for a while before he finally understood what Qiu Yu meant. Her face was full of admiration, and she turned around and gave Qiu Yu a thumbs up, and said, "You are really not an ordinary cow, it seems that my apprentice is decided." As soon as he finished speaking, as if he had thought of something, he hurriedly lowered his head, not daring to look at Qiu Yu again, his pretty face was already red as an apple.

Qiu Yu looked at the computer intently, not noticing her strangeness at all.

"With these traces, it can be determined that the deceased must have been subjected to inhuman torture before his death. For each point of upward movement of the stone pier, the legs of the deceased will be separated by one point, and the higher the up, the greater the angle at which the legs are separated. It's like when we were training our legs at the police academy, the coach made you tear your hips desperately, and I still can't forget the pain. ”

"You mean, that's how the Red Devils torture their victims and force them to confess what they want to know, right?" Wang Bing's face was flushed, but he said very seriously.

"That's right, it's a good thing that the floor of this family is not flat, and the blood flows out of the body and converges in one direction, otherwise, once it is covered with blood, these traces will be difficult to see. Even if it can be found after cleaning, it has been damaged, and it is extremely easy to make deviations in analysis and judgment. Qiu Yu showed a trace of doubt in his eyes, and said slowly: "After reading these live photos today, I found that I seemed to have missed something before. He thought for a while, then suddenly turned his head to look at Wang Bing, and continued: "Have you noticed that there is a common feature at the scene of these cases. The suspects have cleaned up the scene, but not completely. He kept all the things related to crime, but all the things related to himself were erased by him. ”

Hearing this, Wang Bing looked puzzled, and was desperately thinking about the meaning of these words, but heard Qiu Yu ask, "What's wrong with you?" Isn't it uncomfortable? Why is your face so red? ”

"Uh...... Nothing, it was too hot. Wang Bing said with an embarrassed face.

"Well, it's a little hot, indeed." Qiu Yu nodded, not finding any abnormality in her, and said, "In the first three scenes, he didn't leave any fingerprints, footprints, and DNA. This scene is especially obvious, all the footprints in the entire room have been swept by him, but those friction marks have been left intact. The foot he kicked when he entered the door, the extremely blurry footprint left on the door, was obviously erased by his deliberate rubbing with the sole of his shoe. His face was solemn, and he said, "I really don't understand, what is the purpose of the suspect doing this?" ”
