Wang Dali and I returned to the room where the murder took place, I looked towards the ceiling and vaguely saw some stains, just as I expected!
Because there was still a dead man lying on the bed, it was impossible for me to step on the body, so I asked Wang Dali to go and carry a ladder over for me. Then I took a bottle of alcohol and a cotton swab from the technical team's toolbox.
In a short while Wang Dali carried the ladder, I told him to set it up, Wang Dali asked me in confusion, "Yangzi, what are you doing?"
"You'll find out later."
I stepped on the ladder and went up, using a cotton swab dipped in alcohol to gently rub a few times on the stains on the ceiling, the alcohol melted the stains, then the alcohol evaporated and the stains stayed on the cotton swabs, which is how forensic doctors collect liquid physical evidence.
I put the cotton swab under my nose and sniffed it, then asked Wang Dali to sniff it as well, he shook his head and said, "I don't smell anything."
"No, this is eel blood, someone applied it to the ceiling to attract bats." I looked towards the ceiling and added, "Wait, this shape should have been sprayed on with a water gun or something ..."
"Song Yang, come over here!" Huang Xiaotao shouted from the other room.
We went back to that room and Huang Xiaotao made some discoveries, she found an image in another video, the one taken in the same room the day before the murder. A guy wearing a mask dressed as a janitor sneaked in, nailed a nail in the wall, and then pulled out a water gun and shot some kind of liquid at the ceiling.
I told him about the eel blood I just found on the ceiling, and laughed, "Bats are naturally bloodthirsty, and they especially like eel blood, which has the heaviest fishy odor, and that's why the bats were attracted to it!"
"This is enough to prove that the murderer is a human, not some vampire."
Xiao Zhou's face was green for a while and red for a while as he said, "Maybe the magic of vampires being able to recruit bats is fake, but everything else is true, and there is always a gap between reality and legend."
I can kind of see that Xiao Zhou thought it was a vampire that was committing the crime from the beginning to the end, and also when he bet with me before, since he had to be so insistent, I also had to return the favor by doing the same thing to him, "If he is a vampire, then we should have not seen anything just now."
"What do you mean?" Cho asked.
"Vampires can't look in the mirror, much less be photographed, you should have heard of this legend, right? Then the camera shouldn't be able to capture him either."
Xiao Zhou stammered, "This legend could also be false!"
Wang Dali couldn't help but say, "This is also fake, that is also fake, the book you read is fake, right?"
Xiao Zhou was ashamed for a while and said forcefully, "The principle of a camcorder is different from that of a mirror or a camera, maybe a camcorder can capture the image of a vampire."
I said: "If he is really a vampire, then I am afraid that the bodies bitten by him would not be lying there obediently for us to check, and may have turned into zombies and jumped up to attack us, this is a good enough reason, right?"
Xiao Zhou finally made a concession, "Okay, I admit that the murderer this time is not a vampire, but there are vampires in this world!"
A dead duck's mouth, I thought to myself, if there were really vampires in the world, according to their ageless and immortal virtues, there would have been no humans left long ago.
Huang Xiaotao rewound that image and rewatched it twice, frowning, "Can't this image be enlarged?"
The waiter timidly said, "This isn't a high-class camera, which has that kind of function."
Huang Xiaotao asked me, "Song Yang, have you found anything yet?"
I stared at the screen and said, "This cleaner should be the murderer's accomplice, aged forty-five to fifty years old, weighing about 80 kilograms, with a medium build, looking at his technique he should be quite skillful, spraying eel blood on the ceiling, probably knowing from the start that there might be a camcorder hidden here."
"This can be discovered, this person is also a thief!" Huang Xiaotao said.
Uncle calmly guessed from the side, "Probably worked in a hotel before, small hotels like this without a formal license will install camera heads behind mirrors and TVs."
"Also he's had a stroke before." I said.
The crowd was shocked, and Huang Xiaotao asked, "How can you tell this? Can your eyes see through?"
I laughed, "Of course I can't, the clue is inside this video, if you don't believe me, look again!"
Huang Xiaotao rewound the video and rewatched it twice more, she shook her head, "Song Yang, I really don't have your eyesight, just remind me."
Uncle frowned, "I noticed that he walks with a bit of a limp, is this it?"
I stretched out a finger: "This is one of them, I can't assert it based on this alone, there is another point ..."
I took the remote and stepped back a little. The janitor casually leaned his broom against the wall as he entered, and I pointed to his wrist, "You see, his left sleeve doesn't cover his wrist."
"And?" Huang Xiaotao asked.
I fast-forwarded a little more and pressed pause when the older man pulled out the water gun from his right pants pocket, "And look at the right hand, the sleeve of his right hand covers even the back of his hand, which means that his left and right hands are not the same length! This is the aftermath of a stroke."
Xiao Zhou shook his head, "Not necessarily, maybe it's just that the clothes don't fit, and the sleeves are different lengths on both sides."
I said, "This kind of thing may not be impossible, but combined with his slight limp movements when he walks, isn't the after-effects of the stroke a bit more likely?"
The crowd was convinced for a while, and Huang Xiaotao said admiringly, "Indeed, what Song Yang said makes a bit more sense, but you even know all of this, I'm less and less convinced that you're an ordinary college student ..."
Wang Dali took his hand and shook it in front of my eyes, saying, "Yangzi, how did you grow these eyes, why can you see it when none of us can."
I humbly smiled, in fact, knowing the various pathological features is also the basic common sense of the coroner.
Knowing these characteristics, it was much easier to find this accomplice, and soon Huang Xiaotao pulled up the hotel's occupancy records.
The cleaner is called Zhao Tie Niu, a fifty-year-old farmer, originating from a small village around the city.
From the clues we have, Zhao Tieh Niu used his own ID card to open a room for two days beforehand, and then pretended to be a cleaner to come in and do some tricks. The next day the killer brought the deceased to the room and killed him, so the killer left no clues at all.
In addition, the day the monitor in the corridor was twisted at an angle, sloppy hotel staff completely missed, so did not shoot the murderer's face, Huang Xiaotao suspected that this is also Zhao Tieh Niu.
However, I found some doubts, said to Huang Xiaotao: "This is very strange ah, the accomplice since disguised as a cleaner to sneak in, that is an indication of the unwillingness to be seen in the face, why do you want to use your own ID card to open a room?"
"You mean ..."
"The ID should be fake!" I said.
"No matter what, it's also a clue ..." Huang Xiaotao said to a police officer, "Xiao Xu, you go to the household registration management department to check this Zhao Tie Niu."
Then, Huang Xiaotao said to me, "I'll ask Wang Yuanzhao to send you and Wang Dali back to school."
"Wang Yuanzhao?" I was puzzled for a while.
It turned out that she was referring to the silent uncle, Huang Xiaotao laughed, "Officer Wang used to be the Chief Instructor of the Armed Police, and then he was transferred to the Criminal Police Force because of his injuries, don't look at him as a stuffy person, but his hands are quite formidable! I'll send him to pick you up at the scene in the future, you're a piece of treasure in the task force, you mustn't go wrong."
"Thanks for your kind words." Then I smiled at the older man and said, "Officer Wang, thank you."
Wang Yuanzhao just nodded coldly.
Wang Dali patted Wang Yuanzhao and said, "I thought you were just an ordinary uncle before, I can't tell, Chief Instructor's kung fu must be awesome, right? Wasn't Lin Chong, the leopard head in Water Margin, the head instructor of the 800,000-strong forbidden army?"
Xiao Zhou said, "Team Leader Huang, are you remembering wrongly, wasn't Instructor General Wang demoted to a police officer because he disobeyed orders and grilled sixteen drug lords?"
Wang Dali opened his mouth and slowly moved his hand away from Wang Yuanzhao, and Huang Xiaotao glared at Xiao Zhou with an expression that said, "Xiao Zhou, you'll die if you don't talk!"
Wang Yuanzhao waved his hand lightly, "It's all in the past."
I can not help but look at Wang Yuanzhao's eyes a few more points of awe, this uncle looked like an iceberg, the original heart is a blazing fire, see his gloomy look, there may be a tendency to violence.
We returned to the scene of the murder, the police officers will be examined before the body packed up, I routinely burned some paper to the deceased, recited a section of the mantra of the past life.
Huang Xiaotao clapped his hands and said, "Alright, it's already three in the morning, everyone go back to rest, tomorrow at eight in the morning we'll have a case discussion meeting, whoever is late deducts the bonus!"
I asked, "Do I have to come too?"
"Must come!"
"Then the rule of deducting bonuses for being late doesn't include me, right?" I asked weakly.
Huang Xiaotao fiercely squeezed her small pink fist, "You try!"
