"Anyway, there was no filming of the process of the murderer throwing the body, but there was an eyewitness, a scrap picker, who vaguely saw a person riding an old bicycle from near the grove that day, according to him, the bicycle should be the model of Erliu......"

Throwing the corpse on a bicycle and riding away is also in line with the general law of crime, but Lei Tiandong rolled his eyes again: "Erliu's old car, even if everyone now takes the bus or drives when they go out, but the Erliu car in the entire Yujing is afraid that there are no less than 500,000 cars, right? Even if the scope is narrowed down to the western suburbs, it will have to be tens of thousands of cars, if you really want to investigate, just by the model, it is like looking for a needle in a haystack!"

Liu Fengtian and his subordinates didn't understand this truth, but because there were very few clues in the serial demon case, they had to classify this as a clue to be investigated.

Yang Tang also echoed: "Liu Ju, I agree with the bald head, the bicycle line is not just looking for a needle in a haystack, and the possibility of finding it is very small...... As we all know, in the past two or three years, there have been more and more private cars, in addition to high-end fitness bikes can be sold at affordable prices, ordinary bicycles as long as they are a little older, it is a throwing life, no one steals it if it is not locked there, and there are few people who really want to lose an old bicycle and call the police, so there is no way to check!"

Liu Fengtian's eyes lit up when he heard this: "Xiao Yang is right, but what he said just now also reminded me, in case the bicycle seen by the witness is really lost, and it happens that the owner of the bicycle is called the police again......"

Several investigators of the special case group who were still sticking to their posts were all shocked when they heard Liu Fengtian's words, and this was not a way for a blind cat to kill a mouse.

Sure enough, Liu Fengtian immediately assigned the task and asked two of the investigators to immediately implement the matter and check whether the sub-bureaus around the crime site had received a report of the loss of the bicycle.

Turning around, Liu Fengtian continued to introduce the case: "The third body, a female student from Jinghua University, was found last weekend, and after forensic examination, when she was found, she had been dead for less than 48 hours. ”

"Where is the place of death?" asked Lei Tiandong.

"It's in the grass northeast of Jinghua Road Green Park. Liu Fengtian said that there was a fierce light in his eyes, "It's really infuriating, the surveillance video in that area was mistakenly deleted by the people in the monitoring management room on the first day." ”

Lei Tiandong laughed when he heard this: "Isn't it Bureau Liu, the case happened on the second day, who would believe this kind of nonsense by mistake?"

Liu Fengtian waved his hand and said: "This is not a nonsense, but Jinghua is like this every month, on the second or third Friday of the month, the surveillance video from three months ago will be deleted, otherwise the hard disk is not enough to record, and that day it was just a new work-study student who misoperated, and as a result, all the videos within three months were ......."

Lei Tiandong said when he heard this: "This explanation seems reasonable, but there are too many coincidences, do you believe this? Anyway, I don't believe it, Boss Yang, do you believe it?"

The old god Yang Tang said: "I naturally don't believe it. After a pause, he said: "Liu Ju, as far as I know, there are generally two ways to delete a video, one is the view method, click [Delete] After that, a dialog box will pop up, asking you if you are sure to delete, which gives the operator a chance to regret it; as for the second command-line way to delete, it is more difficult to make a mistake, it is to enter in a fixed time format to inform the system that I want to delete the video data from which point in time to which point in time, after the system accepts the command, it will also bounce back to confirm the execution of the command, yes or no, so if you think about it carefully, you will find that there is something strange about the accidental deletion. ”

Liu Fengtian raised his eyebrows and said, "Comrade Xiao Yang, the information you provided is very important, and I will send someone to investigate." ”

"Slow!" Yang Tang stopped Liu Fengtian, who had picked up the internal phone, "Bureau Liu, there is another situation you may not know, as far as I know, there is a swimming pool in the north of the Green Park, and now that the weather is gradually getting warmer, there are already students who dare to go down to play in the water." ”

Liu Fengtian was stunned for a moment: "Then what does this have to do with the case?"

"It's a big deal...... This boy and girl are all playing in the water, a large group of people are crowded there, it is inevitable that they will be jealous, what kind of friction, in case a group of people fight, this is the school ugly, Jinghua School may not be publicized!" Yang Tang seemed to be a donkey's lips and said to the horse's mouth, "And I believe that if such a thing really happens, there will definitely be a lot of people watching the show, and there will be secretly filmed, as long as someone shoots, this may be filmed anywhere." ”

Liu Fengtian's eyes became brighter and brighter when he heard this, and finally clapped his hands and said: "I'll find someone to inquire, if there is really a similar incident, Lao Tzu is the whole school of Dasuo Jinghua, and I have to find out all the videos of that day to ......" Soon, the task was assigned.

At this time, Yang Tang made a request: "Bureau Liu, my colleagues and I want to see the bodies of the three victims, as well as the physical evidence related to them, don't you know if it's convenient?"

Liu Fengtian was in a good mood, and he didn't pay attention to this little request: "No problem, Xiao Yang, but the body of the first bureau was parked at the Shijingshan District Bureau, and it has not been transported to our city bureau for the time being." ”

Yang Tang didn't ask why, but said: "It's okay, I'll look at the last two corpses with the bald head first, and then go to Shijing Mountain to run alone." ”

"Okay, Zhang Jian, it's up to you to take Xiao Yang and them to the forensic examination center to have a look!"

"Yes, Bureau Liu. ”

With Zhang Jian driving the way, Yang Lei and the others followed behind on the motorcycle, and it didn't take long for them to arrive at the forensic examination center. After contacting the deputy director surnamed Li who was on night duty at the center, Yang Tang and Lei Tiandong were finally allowed to enter the exclusive laboratory of the 219 Demon Case.

The exclusive examination room was a large room, divided into four rooms, and the bodies of the two victims were parked in the third compartment coldly, covered with white cloth.

After all the headlights in the room were turned on, I listened to Deputy Director Li's introduction: "It looks like the conditions here are a little simple, but there is no shortage of equipment, the outermost compartment is used for office, writing reports to receive foreign guests, the second compartment is for physical evidence testing, the third compartment is for autopsy, and finally processing and preparing tools or something." Between the words, he had already led Yang Tang and the three of them to the third compartment, entered the password, and pushed the door in.

Facing the two corpses covered with white cloths, none of the four people present showed discomfort, and Deputy Director Li took the initiative to say: "All the reports are in duplicate, one paper has been archived, and the other electronic one is stored in the computer, do you want to see it now?"

At this time, Yang Tang had already come to one of the corpses, waved his hand and said, "You don't need to read the report, this ...... Can you open it and take a look?"

"Please!"

After obtaining permission, Lei Tiandong tacitly pushed the bed of another corpse over to side with the one next to Yang Tang, and then the two of them uncovered the cloth in unison.

Two pale cyan female corpses were displayed in front of the four of them, and Zhang Jian not only pulled the corners of his mouth.

Yang Lei and the others observed and found that in addition to the pale cyan color of the two corpses, there were some wounds sutured after the autopsy on the two corpses, and the location of the wounds was similar, but there were still slight differences, but the bruises and pinching on the corpses were all in exactly the same position, for example, the two corpses were of different lengths, one on the left was high, and the other was low on the right, but there was a pinch mark on the fifth rib under their left rib, and the position was impartial, as if they had measured it with a ruler.

Yang Tang pointed out this question to Deputy Director Li and Zhang Jian, and asked casually: "Is there a detailed description of such a question in the autopsy report?"

Deputy Director Li said: "There is no ordinary autopsy report, but there is a supplementary report of the expert demonstration team, and the analysis says that the criminal must have relevant experience, otherwise it is impossible for every victim to be so accurate!"

Just as Yang Tang was communicating with Deputy Director Li, Lei Tiandong's big hand groped carefully under the cheeks of the two corpses for a while, and finally wondered: "Strange...... The two victims were strangled to death, judging by the pinch scoop dents on their necks, the perpetrator's hands were not strong, but the shape of his hands was completely the shape of a man's hands?"

As soon as these words came out, everyone present was surprised. Zhang Jian even widened his eyes and said, "Investigator Lei, are you sure that you won't make a mistake in your groping technique?"

Lei Tiandong glanced at Zhang Jian with contempt, and said proudly: "If I make a mistake, I would have died a long time ago, and I can still stand here and breathe?"

"Dead?" Zhang Jian said in surprise, "I don't know what Detective Lei used to do?"

"Hehe, it's nothing, field medic!"

Hearing this, Zhang Jian and Deputy Director Li were in awe.

Yang Tang didn't think anything, but learned from Lei Tiandong's appearance just now, and carefully touched the cheeks of the two female corpses: "Hmm...... Indeed, the force of the murderer's hand was not great, and he did not choke the victim's neck bone, but he should have choked the victim's neck for a long time, and eventually caused the victim to suffocate to death!"

"You're right!" Lei Tian said, "It seems that although this criminal has little strength, he has a very ferocious personality! By the way, Director Li, have you extracted anything from the victim's lower body?"

Deputy Director Li was stunned for a moment, and said: "You didn't mention that I almost forgot, I have been busy with this matter for the past two days, and the analysis of the body fluid sample taken from the lower body of the third corpse has come out, except for a trace of unknown chemical liquid, most of the rest of the body fluids belong to the victim, and like the previous two cases, the body fluids of the perpetrator or ** cannot be extracted!"

When Lei Tiandong heard this, he couldn't help but scold: "Damn, this criminal is too careful, right?"

"Nonsense! Just based on these things committed by the other party, he caught a certain death sentence, if he is not careful, can he do it?" Yang Tang complained, turned around and took a closer look at the body of the third victim, "Has the identity of the third victim been identified?"

Zhang Jiandao: "It has long been found out that it is a freshman girl in Jinghua, named Liu Shishi, a strong competitor in the flowers, a good girl in the eyes of teachers and classmates, and her popularity is good......"

"Stop, Director Zhang...... According to my observation, this victim should still be the eldest daughter of Huanghua in front of her, right?" Speaking of this, Yang Tang looked at Deputy Director Li, "At the time of the crime, she was violated, is there a detailed report on the 'torn lower body'?"

"Yes!" Deputy Director Li obviously had a superb job, and immediately recited: "The report says that the laceration of the lower inner lining of victim No. 3 is an instantaneous trauma, not a slow trauma, that is, at that time, the perpetrator suddenly entered the victim's lower body without the victim's psychological preparation, causing the intima to burst and form a laceration. ”

"Spicy hands destroy flowers, rough and cruel!" Lei Tiandong gritted his teeth.

Yang Tang was thoughtful and did not echo Lei Tiandong's words. Soon, he came back to his senses and took the initiative to help cover the corpse, saying, "Okay, the corpse doesn't need to be looked at anymore, we want to see the physical evidence recovered at the scene again!"

Deputy Director Li was noncommittal, took them to the second compartment, and tirelessly introduced: "Every time the bodies are found, the change on their bodies, as well as the cards in their wallets, and all kinds of documents are not lost......"

Yang Tang, who was wearing gloves and rummaging through the wallets of one of the victims, said, "Really?

"The facts are obvious, don't believe it, you see for yourself that there are still dozens of dollars left in their wallets, and their mobile phones are all there, but they are broken!" Deputy Director Li said.

Yang Tang snorted: "We won't discuss whether the mobile phone is broken or artificially damaged, but one of the two women's wallets is seventy and the other is forty, do you think this is reasonable?"

Lei Tiandong tilted his head and asked, "What's the matter?"

"It's not unreasonable, I always feel that something is a little strange...... "Yang Tang muttered, "Bald, how much money you have in your wallet now, take it out and I'll take a look!"

"What are you doing? want to rob you?" said Lei Tiandong, but he still took out his wallet, opened it and counted it, "There are more than seven hundred and twenty yuan, right? What, you want to borrow money?"

"Borrow a fart!" While Yang Tang said this, he asked the red queen to check the two victims' respective bank cards, and the information fed back was as he expected, and there were only a few dozen yuan left in each card.

However, Yang Tang, who had almost guessed the true purpose of the murderer, had to pretend to ask Deputy Director Li: "Is there a computer with an external network?"

"...... right in the office next door"

So the four of them came to the next office, and Yang Tang copied the card numbers of the two victims on a piece of paper and brought them over. After opening the web browser, Yang Tang quickly jumped to the official website of Huaxia Bank and began to enter the Huaxia bank card number of one of the victims.

"What the hell are you doing?" asked Lei Tiandong.

"You'll know right away. Yang Tang entered the password given by the red queen while responding to the harmony, and the next second, the detailed list of card numbers popped up, "Dangdangdang, see no, the balance is forty-nine yuan and two cents and eight; the second one, the balance is seventy-seven yuan and one cent and three; the third chapter, the balance is ......"

Zhang Jian was surprised: "There are only a few dozen balances left in each card, what's going on?"

"Director Zhang, don't you understand? If it weren't for the fact that the ATM could only withdraw one hundred and one hundred whole coins, I think the balance in each card would be cleared, right?"
