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

.It is indeed able to penetrate slowly !

.At the same time .

.Looking at Su Yuan whose expression changed in front of him , Wang Mo also continued to speak .

.” At present , the detection department of the police station is conducting DNA and blood tests on the knife handle . ”

.” I’m afraid it won’t be a few hours before a conclusion can be drawn . ”

.As soon as the voice fell , the entire classroom fell into silence again .

.And Su Yuan after listening to all this .

.Still speaking .

.” I do hope that time can be faster , so that I can prove my innocence . ”

.Su Yuan understood that although Wang Mo’s words were all reasonable .

.But know .

.He also used chemicals to soak the murder weapon .

.So. _

.It is also possible that there is no blood or DNA residue .

.” If the time comes , there will be nothing in the knives . ”

.” Officer Wang Mo , can you rule out your suspicions about me ?” Su Yuan was still talking .

.And listen to his voice .

.Wang Mo smiled .

.” You think . ”

.” Have we only found this key piece of evidence ?”

.Seeing the smile on Wang Mo’s face , Su Yuan instantly felt a chill on his back .

.And Wang Mo’s voice was still sounding slowly .

.” In the beginning , I wanted to go through the situation in the anatomical room to carry out the next step of investigation . ”

.” But in our preliminary investigation, we found that on the night of the rainstorm on March 1 , due to the power outage and holiday of the college , in the early hours of the morning , almost no one existed in the school . ”

.” You can put the three corpses into the underground corpse pool of the dissection room without leaving any clues . ”

.” And you , you are also using a lock-picking method to open the door of the planing room . ”

.” It ‘s exactly the same way you opened the door of that peasant couple twenty years ago !”

.Twenty years ago .

.In the rainstorm butcher serial murder case .

.There is a group of suburban couples who were directly pried open by the rainstorm butcher , and then brutally murdered .

.” So when I was sure that I couldn’t find clues from this point , I quickly reversed the direction of the investigation . ”

.” Just that night , I opened the previous file again , and Shen Nan’s confession , looking for clues . ”

.” Finally . ”

.” Found a key piece of information !”.

Chapter 107 , Rainstorm Butcher , officially arrested ! ( The case is over !)

.When it comes to this .

.Wang Mo paused for a while .

.And Su Yuan on the podium actually found himself feeling nervous .

.But he quickly consoled himself .

.Wang Mo’s move might be deceiving himself .

.So continue to pretend to be calm .

.But Wang Mo’s voice was still sounding slowly .

.” When I opened the previous file information and confessed to Shen Nan , I suddenly thought of a very important point . ”

.” There are no traces of bone cracks or fractures on all the suspicious specimens at present . ”

.” But from your previous killing methods, the deceased who died in your hands are basically scarred , many wounds , and even deep bones , fractures and fractures are common occurrences . ”

.” Even , every skeleton in your burial ground , basically , has traces of bone cracks . ”

.” But in the medical school, there are no scratches on these bone specimens . ”

.” That is to say . ”

.” On victims of disappearances within medical school . ”

.Wang Mo paused .

.” You changed your way of killing . ”

.when the word is spoken .

.Su Yuan has been unable to keep his composure , and his face has become a little ugly .

.He is facing .

.Subconsciously glanced at the sternum specimen on the podium next to it .

.He had already roughly guessed what Wang Mo wanted to say !

.But in his heart .

.In fact, there is still some hope .

.Maybe .

.What Wang Mo said now .

.Isn’t that so ?

.Available in classrooms .

.Wang Mo’s voice continued to echo .

.” So all the missing persons in 2004 in the past 11 years , you are not violent killing and dismembering the body . ”

.” Instead . ”

.” Poison them !”

.” Then , the corpse is divided , dissolved , and made into bone specimens . ”

.” So during this process , there were no scars on any of the bones . ”

.” In order to make your own specimens perfect , you even gave up the step of cannibalism !”

.When it comes to here .

.Su Yuan’s face turned pale .

.But Wang Mo’s words still did n’t stop .

.” And there are actually only a few kinds of chemicals that can directly poison people to death in a short period of time , but they are all strictly controlled . ”

.” I think so . ”

.” You should have used your status as a professor to let these victims let their guard down on you , and then you poisoned them . ”

.” Of course , it is not enough to know the cause of death of these missing persons . ”

.” We have to find out what chemical they were poisoned by . ”

.between words .

.Wang Mo’s sight .

.He has been staring coldly at Su Yuan in front of him .

.” Originally , corpses that have been made into bone specimens will not leave too many clues of poisoning during their lifetime . ”

.” Even with testing , nothing can be detected . ”

.” There are several toxic chemicals that can leave permanent traces on the bones of the deceased ! ”

.When it comes to here .

.Wang Mo slowly put on disposable dust-free gloves .

.came .

.On the podium , next to a sternum specimen .

.At this time, Su Yuan’s face was already ugly and pale to the extreme .

.And Wang Mo’s voice is still sounding slowly

.” After locking in this direction of investigation , we tested some of the suspicious bone specimens that had been discovered at the time . ”

.” At the time , we didn’t have much hope in this regard . ”

.” After all , bones that have become specimens are unlikely to leave much information about poisoning during their lifetime . ”

.” And in the process , we were pleasantly surprised . ”

.” You actually used the highly toxic chemical that will leave the biggest traces !”

.between words .

.Wang Mo has slowly picked up the sternum specimen .

.Subsequently .

.In the larger bones above , groping for something .

.Watching Wang Mo’s actions .

.Su Yuan’s forehead could not help oozing cold sweat .

.And the next second .

.Wang Mo also found a relatively fragile bone in this specimen .

.Subsequently .

.He smiled at Su Yuan .

.” Finally . ”

.” We still found out , what are the highly toxic chemicals you use !”

.A click .

.Wang Mo lightly exerted force .

.This relatively fragile bone was directly broken by him !

.On the outside , it looks like a white and flawless skeleton specimen .

.Lateral section of a broken bone .

.Actually .
