Why, what! 】

After accessing the surveillance video, Dai Xu and Fang Yuanzai carefully looked at the surveillance screen during that period of time, and found that the public telephone in the green space, don't look at most of the passers-by who passed by there did not pay much attention, but there are still curious people, you can see from the surveillance screen, during that time, there are really people to fiddle with the telephone, there is a little boy who passes here with a schoolbag after school, about eight or nine years old, very lively running and jumping, When he saw the phone, he immediately ran over and grabbed it, and was soon scolded by the parents who picked him up from school, and gestured to let the child quickly put down the phone and go with him, and the little boy reluctantly put down the receiver and followed the parents out of there. Walked away.

After that, after a while, someone passed by again. It was a young man who looked to be in his twenties and thirties, wearing a brown-black woolen coat and carrying a paper bag in his hand, his head was slightly lowered when he walked, and the camera was relatively high, so his face was not very clear. He saw the IC card payphone, and his pace slowed down a little. As if for a moment, he quickly changed his direction and stepped into the green area and walked towards the telephone. The time was not far from Yang Cheng receiving an anonymous call to report the crime, which made Dai Xu and Fang Yuan feel very excited, but judging from the next picture, this person didn't look like he was going to make a call. He picked up the IC card phone. I put the earpiece close to my ear, listened carefully to the sound, and confirmed that it was a telephone that could still be used, so I paused for a while, and then put the earpiece to my cheek, pressed a string of numbers in the dial area, and played as if I was listening carefully to the sound inside the earpiece. When he finished dialing the number, he listened for a while. He hung up the phone receiver back and walked away alone.

"This person shouldn't be calling, right?" After Fang Yuan finished reading it, he asked Dai Xu with some doubts, "I feel that he has dialed many numbers, not like the digits of ordinary landline numbers, and even mobile phone numbers don't need to be dialed so many times, right?" Also, if I'm not mistaken, this person didn't have a card at all, right? ”

"Well, if you look closely, he really didn't insert the card!" Dai Xu adjusted the video screen forward a little bit, and watched the man's action of walking away immediately after hanging up, "I guess, this person is purely curious." ”

"Curiosity needs to dial so many numbers, and have you listened to it for so long?" Fang Yuan was puzzled.

Dai Xu smiled: "This shows that there is still a gap between the ages of the two of us." When I was in middle school, IC card phone was also very special and common, for a period of time, I don't know who found it, a total of one to ten, ten to hundred, a loophole about the IC card phone was spread to everyone, that is, there is such a set of numbers, what to broadcast first, and then what to broadcast, a large string of numbers and asterisks, pound combinations, I can't remember now, but I remember very clearly, as long as you dial that group of numbers in accordance with the correct method, you can make free calls without inserting the card. If you think about it, as soon as this kind of thing gets out, of course, there are many people who want to take advantage. I was also a poor student at the time, I didn't have much pocket money in my pocket, and although I didn't know who to call, I still wanted to give it a try when I had a free phone to call. However, later the communication company found out and made modifications and adjustments, and the original string of numbers did not work. After a period of time, a new number was cracked, and the communication company adjusted again, and the cycle continued, until later mobile phones began to become more and more popular, and fewer and fewer people needed to make IC card calls, and then they were basically forgotten. ”

"I see!" Fang Yuan really didn't know such a thing about the IC card phone, and after listening to it, he suddenly realized, "So that person may have seen that there is also an IC card public phone here, so he looked at it curiously, and found that it can actually be used, it just so happened that he might also know what kind of cracked number, so he was curious, so he simply tried it?" When you say that, it really looks like that. ”

"I just guessed casually, at least as you said, he didn't insert and pull cards from beginning to end, it doesn't seem like he was calling our bureau, and when he called, he also needed to be transferred to the Yang team, and the time in between must be much longer than the time this person held the receiver, so he definitely won't be the person we are looking for." Dai Xu motioned for Fang Yuan to continue watching the surveillance video.

The surveillance footage advanced for a few more minutes, and there were pedestrians passing by the side of the road from time to time, but no one stopped in front of the IC card payphone, and after a while, finally a person walked towards the phone again.

This person is wearing a black coat, it is not clear from the picture whether it is thin down or filled with cotton, the coat is knee-length, it is a lapel style, the collar is erected by him, this person is of medium height, he is not tall or inconspicuous when he walks on the road, he has a black hat woven of certain wool on his head, a knitted scarf with stripes tied around his neck that cannot be seen whether it is black or navy blue, and a pair of gloves on his hands. Although it is said that it is already spring, but in the warm and cold season, City A is notoriously windy. This dress does not look abrupt on the street. The man walked down the street with some huddle, and he seemed to have known that there was a public telephone in the green space by the side of the road, so he didn't look around at all. Instead, he walked straight to the payphone, pulled something out of his pocket, grabbed the receiver, and dialed.

"It's supposed to be a calling card, right? This person obviously knows that the phone is an IC card public phone, and it is still easy to use! You see, he even has the cards ready in advance! When Fang Yuan saw this scene, he immediately cheered up. Pointing to the screen on the screen, "And this person does seem to be on the phone, not just messing around!" ”

Dai Xu nodded. Also pay close attention to the person in the picture.

The man was indeed on the phone, and after the number was broadcast, he stood next to the phone booth for almost five minutes with the phone receiver in his handset, due to the distance of the camera. Even when cut to the maximum screen. There is no way to see very clearly, and there is only an image, no sound, and naturally there is no way to know where this person called and what he said, only to see that this person hung up the telephone receiver after dialing the number for about five minutes, and lowered his head slightly. The footsteps hurriedly walked away, and soon disappeared to the edge of the picture.

Fang Yuan looked at Dai Xu. She felt that this time they must have found the mysterious informant who made an anonymous call to call the police, but Dai Xu was calmer than her, and broadcast the surveillance video backwards at a fast-forward speed, making sure that no one had touched the phone again during this period of time, so she reverted the picture back to the time period when the caller was there, ruling out the possibility that there were other people, and making the man in the woolen hat the person who was most likely the mysterious informant.

It's a pity that a few days have passed since the time of the call, and the second is that the man wearing a woolen hat is still wearing gloves on his hands, so he didn't go to the telephone to extract the fingerprints on the receiver at all, not to mention these, even the person's face can not be seen clearly through the video screen, the only thing that can be determined is that the person who appears in the picture still looks relatively thin, including the age judged by the way he dresses, This is consistent with some information that has been inferred from the footprints in terms of forensic techniques.

Dai Xu cut the picture to the closest, took a full-body picture of the person and printed it out, as well as a close-up of the footsteps, and also printed it out, and showed it to the colleagues of the criminal technique, so that they could judge whether it matched the footprints found at the scene according to the clothes of the person on the screen, especially the shoes on the feet. The colleagues of the criminal technology tried their best to judge the general style of the shoes worn by this person through the characteristics presented on the video screen, and believed that they were also slender and long, although they could not be 100% sure, but the characteristics of the series of footprints left at the scene were still generally consistent, and the degree of consistency should be relatively high.

If his identity can be clarified, then through him, he may also be able to learn about the deceased, or about "Li Jiawei", some information that has not been grasped before. Or, it is also possible that the informant is "Li Jiawei" himself, a person who rented a house with ******** and whose motives are unknown, regardless of whether he has a direct or indirect relationship with the life lawsuit in the house he rents, I am afraid that he will not be willing to go to the public security bureau to report to the police and deal with the police as the informant.

If you want to determine whether this person is "Li Jiawei", or someone related to "Li Jiawei", the most likely to help is naturally the landlord of "Li Jiawei" and the owner and wife of the house at the scene of the crime.

So Dai Xu and Fang Yuan contacted the couple again, got their permission, went to their own residence to ask them about the situation, and asked them to help in the investigation.

The landlord and his wife have also suffered a lot of blows because of this incident, although in general, they do not have much direct loss, a house that is difficult to rent out on weekdays, they have collected the rent for a year and a half in one go, and now even if something happens, no one will want to claim back the rent, but after all, it is their own house that killed people, no matter where in the world the concept is, it is a very frustrating thing, so the two of them are not in a good mood these days, and they seem to be a little listless.

As soon as she saw Dai Xu and Fang Yuan coming to the door, the landlady couldn't help but ask if there was any progress in this matter, but the male landlady was relatively calm and reasonable, and comforted his wife, telling her that if the police made progress, there was no need to make a special appointment with them for further questioning, and for them, whether this case could be solved or not, when it could be solved, who was the murderer, and why did he kill the deceased in the house of their family, which did not mean anything to the two of them themselves. For them, the most important thing is not to cause too much impact on this matter, not to spread it to everyone, in this way, when the dust settles, the people around them slowly forget about it, they can still clean up the house and re-post the advertisement for rent. Therefore, what the landlady is most concerned about is whether Dai Xu and Fang Yuan's investigation work has spread the news of the murder in their house in the past few days.

When they learned that this incident had not been spread and had a great impact, the landlord and his wife were relieved, their spirits were obviously much better, and they began to be in the mood to accept Dai Xu and Fang Yuan's inquiries.

Dai Xu told them about a mysterious informant, and took out the photos of the surveillance footage that he had printed out before, hoping that they could help identify whether the person in the photo was "Li Jiawei" who rented their house and paid the rent for a year and a half in one go. The landlady took the photo, looked at it with the landlady, and then raised his head slightly blankly and looked at Dai Xu.

"Are you all there are pictures? You can't see this person's face on it, huh? The landlady asked with some confusion, and glanced at the photo a few more times, "I can't see a straight face, how can we judge?" ”

"This is the only picture we can get, although there is no front, only some unclear side faces, but the overall appearance characteristics are still relatively obvious, can you see if you can recall what the 'Li Jiawei' who signed the contract with you and rented the house looks like according to these, try to compare?" Dai Xu said that they could not do anything about the lack of positive images.

The landlady nodded reluctantly, and his wife carefully looked through the photos, and finally said that from the photos, according to the small trees on the side of the road, telephone booths, etc. as references, they felt that the man wearing a beanie in the photo looked about the same height as the "Li Jiawei" who rented the house, it should be comparable, and the figure could not be seen really through the coat, so it was hard to say, especially the face could not be seen clearly, this is very bad, after all, this kind of medium-height, medium-sized person, There are many in society, and there is nothing special, just because of these let them judge whether this person is "Li Jiawei" or not, I'm afraid it's really difficult to determine.
