Murong Fei asked with a sad face: "These two cases, apart from the notes at the scene and the injuries to the corpses, from the perspective of investigation, can they see that there are similarities?" ”

Wu Long sighed and said: "From the perspective of investigation, I really don't see any related places, at present, it seems that only the age of the deceased is relatively similar, and the occupation, economic conditions, and family background of the deceased do not seem to be similar." Pen? Interesting? Pavilion wWw. ｂiquge。 info I think the murderer is so deliberate, there should be a certain choice for the deceased, but we haven't dug deep yet, unless the murderer is purely perverted and kills people randomly. ”

Murong Fei turned on the laptop again, and his computer desktop was shown on the projector screen, and the photo of the large wound on his neck jumped in front of him, he switched the photo to the note, and he looked at it seriously for a while and said: "Wulong, I also see it this way, although I can't see the same in the investigation, but the content of this note says, 'Let all the Creators end', I think this 'Creator' should have something to say, right?" ”

Wu Long moved his gaze to the screen of the projector and said: "The murderer said that the creator should have his own standards, he designated these people as the creators, and then killed them one by one, so far, but we haven't seen what the standards of this creator are." ”

Murong Fei later reviewed the scenes of the two cases and the photos of the corpses on the projector, and Wu Long leaned his head on the conference table, squinting at Murong Fei showing the photos.

Murong Fei said while screening: "From a technical point of view, there is no problem with the merger, but these two cases are very bad, except for this note, there is no trace of physical evidence to find, we want to break through, there is no grasp." ”

Chi Ming sat there quietly, drinking tea all the time, he hadn't spoken for a long time, and when he heard Murong Fei talk about trace evidence, he said, "Murong, I think it's just this note, we can also think of a way." ”

Murong Fei quickly switched the photo back to the note, which was magnified several times by the projector on the screen, and the words "Let all the Creators end" were very glaring, and he asked, "Oh? Do you have any good ideas? ”

Chi Ming walked up to Murong Fei and motioned for Murong Fei to hand him the mouse and let him operate the screen.

Murong Fei simply stepped aside and let Chi Ming sit next to the computer.

Chi Ming rolled the mouse, continued to magnify the note several times, only the three words "Creator" were displayed on the screen, he picked up the laser pointer, and the red light point of the laser pointer fell on the edge of the word "Made", and said: "You see, now the image is enlarged, and the edge of this word is a little jagged, this should not be our common printer, such as inkjet printers, laser printers, the fonts printed by these printers should be relatively smooth, and the fonts on this paper strip appear jagged, I think, Only dot matrix printers can print this effect, and dot matrix printers are rarely used these days, so if we can do some work on this printer, we may be able to help the detection narrow down. ”

Wu Long listened to Chi Ming's analysis, he condensed his eyes, and repeatedly looked at the place where Chi Ming's laser dot fell on the screen, he felt that Chi Ming's analysis did have some truth, and thought to himself, if it can be determined that it is a dot matrix printer, it means that this kind of printer may exist next to the murderer, he said: "Yes, the dot matrix printer is now very narrow, although the performance is low, the price is not cheap, the murderer uses a dot matrix printer to print paper, and will not specifically buy a printer like this, indicating that his workplace is likely to have this kind of printer." ”

Murong Fei nodded and said: "And there may only be this kind of printer, this kind of printer is very loud and slow when printing, and it is generally used to set invoices, if there is a better printer around him, he should choose other printers, right?" ”

Chi Ming put down the mouse, turned his face, and said, "Yes, in the case of choice, a dot matrix printer will not be preferred for printing paper on one side." I also know of a situation where online stores now use dot matrix printers to print express delivery labels. ”

Wu Long suddenly interrupted and said, "Oh? Dai Wenshang, who was killed in the case last week, is the courier, could it be that this printer has anything to do with Dai Wenshang? ”

Murong Fei and Chi Ming looked at each other, and Murong Fei said: "Well, it seems that this dot matrix printer may be a clue, Chi Ming, you go back and study it carefully, and see if there is a way to figure out the brand, style, and ribbon of the printer......"

Chi Ming smiled and said: "Team leader, don't take me seriously, just based on these few words, you want me to analyze the brand and style of this printer?" Stop dreaming. ”

Murong Fei glared and said, "Chi Ming, this is what you are looking for, you think that you can help the investigation with just this kind of information about the dot matrix printer, how is it possible?" I said, you should take this matter seriously, this case is just such a thing, you go back and study it carefully, maybe it will work? ”

Chi Ming showed an aggrieved expression and said: "Okay, team leader, I will try to say as little as I can in the future, and try not to say anything if I can, I will study the matter of the printer, but don't take it seriously, I don't have any bottom in my heart." ”

Wu Long saw that Chi Ming was a little embarrassed, so he encouraged: "Chi Ming, I believe you, go to the market to search for a batch of printers and come back, print some paper samples, use your stereo microscope to study it, maybe you can analyze it, you know, if the brand and style are limited, for our investigation, there will be a clear direction." ”

Chi Ming shrugged and said, "Okay, blame me for talking too much, but I'm still a little bit interested in this issue." ”

Wu Long continued: "It seems that my side may do more work on Dai Wenshang last week. ”

Chi Ming got up and left the position of the computer, although he spoke like that just now, but in his heart, why didn't he want to analyze some results from these words? He knows that trace science covers a wide range of issues, and many of them are new problems, and he is never ready to learn while doing them.

He returned to his position, thinking to himself, it is far from enough to only study the brand and style of this dot matrix printer, as well as the ribbon of the printer, in order to really play a role in the case, it is necessary to analyze the characteristics of this printer, just like comparing fingerprints, through these handwritings can determine that it is printed by a certain printer, so that it will be really helpful to the investigation.

Chi Ming thought to himself, this is really a criminal printer.
