Detective: On the first day in office, the serial murder case was solved

.” Since this person has already told Shen Nan most of his killing methods and methods . ”

.” I also want to reinvigorate Shen Nan’s inner desire to kill . ”

.” But why , when Shen Nan finally became a new murderer , you didn’t hesitate to abandon him . ”

.” Even knowing that the police were likely to set a trap , they didn’t give any warning to Shen Nan . ”

.” I have thought about this question for a long time before . ”

.Speaking of which .

.Wang Mo turned his eyes to Su Yuan slowly .

.There was a cold look in his eyes .

.” When I finally locked the identity of the rainstorm butcher as you , I finally understood this in your attitude . ”

0 .?For flowers.

.” From the beginning to the end , in your eyes , there is no difference between Shen Nan and the other dead you killed . ”

.” You have long placed yourself above the lives of others , including Shen Nan . ”

.” Simple killing can no longer satisfy you . It is your current thinking that you want to use the hands of others to kill . ”

.” And you don’t really care who this person is and whether they will be arrested by the police . ”

.” You only care about yourself . ”

.Wang Mo’s speech was not fast .

.” If the police hadn’t discovered your burial , maybe you would never have used the identity of the butcher of the storm to kill again . ”

.”The police officer really knows how to joke . ” At this time , Su Yuan’s eyes were much colder than before .

.He didn’t think so .

�? �

.With just a few words , Wang Mo had already guessed what he was thinking .

.But he continued to speak .

.” If you don’t have evidence , all speculation is just speculation . ”

.Listening to Su Yuan’s voice , Wang Mo’s expression was extremely calm .

.Then he said lightly .

.”The above , indeed, cannot be used as evidence . ”

.” But that doesn’t mean we haven’t found anything . ”

.between words .

.Wang Mo opened the folder in his hand and continued .

.” We investigated for a period of time , and found the murder weapon in the burial ground of Shen Nan , and finally found the source of the murder weapon , which was in a certain suburban grocery store . ”

.” That afternoon , two murder weapons of the same size were bought by the same person . ”

.” Through the portrait , the boss has determined that this person is Shen Nan . ”

.” At that time, Shen Nan bought two controlled knives with a size of more than 20 centimeters by himself . ”

.” And he must have followed your instructions . ”

.” After you have determined your murder plan , let Shen Nan find suitable weapons , or two . ”

.Wang Mo’s voice was not loud .

.But it kept ringing in the classroom .

.” However , I’m afraid Shen Nan doesn’t even know that the weapon you used to kill was not the knife he bought . ”

.” Let him buy two knives , it’s just a little trick of yours . ”

.” If I’m not wrong . ”

.Wang Mo paused .

.” The weapon you used to kill and dismember is actually the knife you used to kill twenty years ago . ”

.” You have kept this murder weapon until now !” Inch .

.Following Wang Mo’s voice .

.reverberates throughout the classroom .

.Su Yuan’s expression also changed slightly .

.And Wang Mo has not stopped the movement in his hand .

.He opened the autopsy reports of three bodies in the autopsy room .

.” I know , you ‘re probably wondering now , how did we know this . ”

.” In your opinion , you left no clue . ”

.” But your idea has a premise . ”

.” That is , the corpses under the anatomy room , and these human skeleton specimens , have not been found by us . ”

.” If these two things are not discovered by the police , it is indeed very difficult for us to find evidence of your murder . ”

.” But we found it . ”

.Wang Mo glanced at Su Yuan and sneered .

.” A few days ago , because of the heavy rain at the time , the scarecrow you made did n’t actually have many clues left on the wound . ”

” Three Four Seven ”

.” But we , after finding the three bodies in the autopsy room , conducted a detailed autopsy on them . ”

.” We found some iron filings and rust residues on the wound surfaces of the three corpses . ”

.” But this kind of trace will never appear on a brand-new knife that has just been made . ”

.” So the moment I saw this autopsy information, I thought . ”

.” The weapon you used is different from the weapon Shen Nan used to kill !”

.” The murder weapon from twenty years ago , you have kept it until now !”

.Today’s knife making process is very different from that of the past .

.In those days , many long knives were made of iron .

.And now .

.Many knives are made of pure steel .

.There is a big difference between the two .

.At the same time .

.Wang Mo’s voice continued to sound .

.” Although you have kept this murder weapon well over the past 20 years , it still has rust and scratches that cannot be erased by time . ”

.” As soon as I sensed it , I quickly deduced it . ”

.” Since all the corpses have been made into specimens by you and placed on your daily trajectory . ”

.” Then if this weapon is left behind by you , you will definitely take it with you as well . ”

.” So , just now , we went to your apartment again and conducted a detailed inspection !”

.talking .

.Wang Mochao threw a few photos on the podium in front of Su Yuan .

.These photos were all taken in Suyuan’s apartment .

.” In your kitchen . ”

.” There are two knives , one of the knives has obvious signs of being worn, and their blades are not made of steel that is commonly used today . ”

.” If I’m not wrong . ”

.” After you discovered Shen Nan and was really arrested , you still dealt with this murder weapon from 20 years ago , just in case . ”

.” But , for some reason . ”

.” Maybe it’s a little reluctant to give up , or maybe it’s because the police won’t find out about this step at all , so you didn’t and gave it up completely . ”

.Wang Mo paused , his eyes glowing like torches .

.” Instead , disconnect the murder weapon from it and polish it again . ”

.”I made it into two large kitchen knives , and put it in my kitchen , bright and undisguised . ”

.After listening , Su Yuan’s brows could not help but frown slightly .

.Immediately retorted .

.” Officer , I like to use knives of this material to cut vegetables . Is it possible that there is a problem ?”

.” If you don’t believe me , you can take these two knives for testing to see if there is any blood and DNA residue . ”

.Listen to Su Yuan’s voice .

.Wang Mo sneered .

.” You say that because you think that you have cleaned up all the blood on it . ”

.” But you’re really sure . ”

.” No message left ?”

.As Wang Mo’s voice fell , Su Yuan frowned again and began to think .

.But Wang Mo’s voice did not stop because of this .

.” After you cut off the murder weapon , the more than 20 centimeters long knife was divided into two parts . ”

.” With the lower part of the handle , you didn’t replace the handle , just finely sand and clean it . ”

.” In the past 20 years , you have used this knife to kill and dismember how many people . ”

.” Blood , I’m afraid the hilt has already been covered with blood . ”

.” Over time , the handle appears to have been cleaned even though there are no marks on the blade . ”

.” But the handle on your murder weapon is a wooden handle after all . ”

.” Over the years , the blood will slowly seep through . ”

.” Not to mention , in some of the corners and corners of the knife handle , it is difficult to be completely cleaned . ”

.When he heard this , Su Yuan’s face was not as calm as before .

.At the beginning .

.He really didn’t think that the police could find out this step , so he didn’t completely discard the murder weapon .

.Also just as Wang Mo said , although after cleaning , the hilt and blade body have no traces . �?

.Can be bloodstained .
