I pulled out a pile of rice paper from the bag and shoved it into Xiao Zhou's hand and said, "Check it yourself to see if I've tampered with it!"
Xiao Zhou glared at me with an ugly face and said to a police officer, "Hurry up and bring my toolbox over."
He opened his toolbox, took out some instruments and reagents, and started scanning the pieces of paper. I didn't bother to pay attention to him, Huang Xiaotao called one of the police officers from the technical team to come over to take pictures for evidence, while I took a closer look at the two handprints.
These two handprints were in the part of the deceased's shoulder blade, the murderer could only appear such a clear imprint if he was pressing the deceased dead and sucking blood!
I used the palm of my hand to compare, this handprint was a cut larger than mine, judging from the shape and size it was an adult male in his twenties to thirties.
However, I found a problem, and Huang Xiaotao also found it, "Song Yang, there are no fingerprints on this handprint at all!"
"What do you think the reason could be?" I asked.
"It's probably because the murderer destroyed his own fingerprints or wore gloves." Huang Xiaotao guessed.
I shook my head and pointed to a few places and said, "Look at the handprints, the lines on the joints are clear, which means the murderer didn't wear gloves when he committed the crime. If the murderer destroyed the fingerprints himself, then there would also be messy creases, but this handprint is very clear and clean ..."
"Then what could be the reason?" Huang Xiaotao adorably held her little head in thought.
At this time Xiao Zhou had already finished testing my rice paper, his face was even more ugly than before, as if he was a purple eggplant.
My rice paper naturally wouldn't have a problem, but this kid just refused to admit it and said in a voice shaking with anger, "How could this kind of bumpkin's tactics possibly win over my equipment!"
"Dead duck's mouth!" I laughed coldly, "It's not that you lost to me, or that your equipment lost to my rustic methods, but that you lost to your own ego. You haven't learned all the lessons left behind by your old ancestors, so you're going to learn some other shit."
"Come, come, fresh soot, eat it while it's hot." Wang Dali brought over the ashtray on the nightstand and handed it to Xiao Zhou, who was so angry that he didn't reach for it.
I took the ashtray and handed it to him, "Come on, willing to bet, you eat it and I'll tell you why you didn't test it."
At this point the other people in the room gathered around to see what was going on, most of them were Xiao Zhou's men, Xiao Zhou viciously yelled at them, "Go away, no looking!" Then he grabbed the ashtray from my hand and poured it into his mouth, but of course most of it was dumped on the floor, a detail I don't care to point out.
Xiao Zhou's mouth was covered with soot, vigorously chewing the cigarette butt in his mouth, a few comical in the sad expression, I couldn't help but want to laugh, take care of his face before forcing to hold back.
Wang Dali does not care about this, while laughing while pounding my shoulder: "Yangzi, look at his appearance, cigarette butts delicious?"
Huang Xiaotao also couldn't hold back his laughter, probably because he was afraid of hurting Xiao Zhou's pride, and deliberately blocked his mouth with his hand.
Cigarette butts are certainly not tasty, Xiao Zhou stretched his neck before swallowing, then wiped his mouth with his sleeve and said, "Go ahead, I'd like to hear what you can say to make sense."
"Western forensic books I have read, you detect the principle of fingerprints is nothing more than these, the human sweat glands will be out of a layer of imperceptible grease, attached to the surface of the object will leave fingerprints, so the use of aluminum powder or ultraviolet light irradiation will be rendered, but this murderer is somewhat special ... "I explained.
"How special?" Xiao Zhou couldn't help but ask curiously.
"He doesn't have sweat glands, or rather, his sweat glands don't have a secretion function." I said.
Xiao Zhou was shocked, "How can a person not have sweat glands!" The other people present also froze for a moment and murmured.
"I actually have to thank you." I said.
"Thank me?" Xiao Zhou was a bit stunned.
"Huang Xiaotao said that you are a high achiever who returned from studying abroad, I believe that you wouldn't even be unable to check a simple fingerprint, which saved me quite a few steps, and I directly used the 'greaseproof paper overlay test method'."
"Wait!" Xiao Zhou said, "Since there are no sweat glands, then where did these two handprints come from?"
"This is called 'Indo-yang marks', at the moment of death, the bioelectric current in a person's muscles will escape from his pores, at this time, if something blocks the surface of the skin, it will leave a clear imprint, no matter if he has no sweat glands or not! Why does a person weigh twenty-one grams less after death? Some say it's the weight of the soul, but in fact it's the total weight of the bioelectric currents that escape." I explained quickly.
Xiao Zhou stared in dismay for a long time before sighing, "You are really extraordinary, it's me who underestimated the old ancestor's learning, I was really offended just now!"
This guy's attitude of admitting his mistake is quite good, unlike Forensic Physician Qin, who is as stinky and hard as a stone in a latrine, I can't help but feel a little good about him and said, "It's okay, you have studied science for so many years, and when you heard that I am a coroner, it's only normal that you don't trust me, and I hope that we can work together well in the future."
"I will definitely be humble and seek advice in the future, I won't be so arrogant anymore." Cho hesitantly extended a hand, and I shook his.
I waved my hand at the police officers who had gathered around, "Go on with the inspection!"
"Still need to examine ah?" Wang Dali asked.
This case did not look ordinary, and I could not care less about the rice paper and camellia oil being expensive, with Wang Dali's help, I examined each of the four parts of the dead man's wrists, waist, thighs, and ankles once.
Oil paper overlay method is very time-consuming, all the examination took nearly an hour, the deceased's wrists have a binding marks, like cloth or silk left, the ankles also have the same binding marks, waist side of each pair of handprints.
While we were doing this, Xiao Zhou was watching from the side, and he was completely bowled over.
I said to him, "Come and help!"
"Oh!" He ran over and asked, "How can I help?"
"You and Power slowly lift the dead man's arms." I said in a commanding tone.
When the two men lifted the arms, I used the listening bone wood on both sides of the dead man's shoulders to take turns listening to the sound, at the same time, I told the people around me not to make any noise, the dead man was born if he was fixed into a certain position, the inside of the joints will secrete a layer of joint lubrication, after death the lubrication solidified, when restored to this position, some extremely subtle and abnormal sounds will be heard.
This mastery of restoring the dead to their pre-mortem posture was called 'Corpse Audit Technique'! It was created by one of the Song family's ancestors, the Secretary of the Da Lisi, Song Tian Yang, and it was said that when Song Tian Yang studied the 'Corpse Auditing Technique' to its highest level, he was able to make the deceased assume the pre-mortem posture by means of a magnetic needle stabbing maneuver, which was so bizarre that it was said to have once driven a government official mad with fear.
This ancestor also once made a corpse 'come alive' on its own in the public hall, pointing out the murderer among several suspects, and the murderer confessed to the crime on the spot.
We kept adjusting and finally discovered the posture of the deceased before he died.
Both hands were raised above the top, as if the crucified Jesus was hung above the wall! To be slaughtered.
I carefully observed that wall, it is reasonable that there should be hooks or something like that here to fix the dead man's hands, I snapped my fingers and found that the wallpaper was freshly pasted on, and there was indeed a hole in the wall behind it.
"There were nails here! Someone glued it on afterward." I shouted.
I unleashed my 'Cave Pixie Pupil' to put my face on the wallpaper for an inch, and found a very subtle bump on the wallpaper, so I ripped the whole thing off, and to my surprise, a section of black insulated wire was revealed behind it.
When installing wires for fire and safety reasons, they are usually buried at the foot of the wall and protected by a plastic pipe on the outside, this wire behind the wallpaper was obviously installed by someone on purpose.
"Find out where it connects to." I said anxiously.
"Come help!"
Xiao Zhou called a few police officers from the technical team, tore open the wallpaper, ripped out the wires one by one, and finally found a pinhole camcorder next to the room's headlamp, facing the bed below.
The people present let out a gasp, and Huang Xiaotao said, "How dare you steal a picture? It's so nasty!"
"But this means that we have a major clue." I said.
Huang Xiaotao nodded and greeted a police officer, "Go bring the person in charge of the hotel here!"
