Chapter 47 "Behind the Sacredness, There Are Lies and Filth!"
Holtz's exclamation was heard inside.
Everyone was mentally prepared.
Go in again.
They were still shocked by the scene before them.
What you see is a fluorescent blue light.
Everyone's exposed skin was mapped into a faint blue color, which was deep and slightly weird at the same time.
"What exactly happened here?" The only female forensic examiner raised her throat: "Did the murderer directly use the blood as water to mop the floor?"
This is a rare and grand scene.
Even these well-informed forensic examiners were in a daze at the moment.
Dean didn't feel anything.
After scanning around, he showed a puzzled look: "These marks seem to be really caused by the mop, but in this case, what is the other party's purpose?"
Although it is difficult to completely clean up the traces left by blood, wouldn't it be more troublesome to clean up if the blood stains are everywhere?
"The murderer is cunning and clever."
Holtz didn't look very good.
He took out a laser pointer from his pocket, clicked a few times on the area with the strongest blue light on the ground, and looked at Dean:
“These locations have an obvious sense of overlapping and staggered levels. There is one location inside that should be the location where the victim suffered severe bleeding or even died.
In order to cover up this place, the murderer deliberately mopped several places around it many times. "
"What's the point of this?" Dean became even more confused.
He had never been exposed to such professional analysis before, so he didn't understand the point of Holz's words.
"This involves blood stain analysis." Holz pointed to the female forensic examiner who was frowning and thinking: "Mellon is a professional blood stain analysis expert in our forensic department, Detective Dean, I think you may need her help. "
The female forensic examiner heard Holtz calling her name, came to her senses, and explained to Dean:
“Forensic doctors have a saying that the corpse can speak.
In fact, it’s not just corpses.
Every drop of blood at the crime scene has its own story.
Through blood droplet sputtering shape, trajectory, testing and other means.
We can infer the date of the crime, the murder weapon, the trajectories and movements of the people involved, the ambidextrous nature of the killer, the type of injury sustained by the victim, and even whether the wound would have been fatal at the time. "
"but."
Mellon frowned again: "This place has been covered with a large amount of blood traces. It is difficult for us to obtain useful information through blood stain analysis."
Make bricks without straw.
The blood stains are all covered, and even a crappy analysis can only identify the time and type of blood existence and whether there is any residual genetic information.
Dean finally understood: "So what you are saying is that the murderer knew the methods that the forensics department might use?"
"Yes." Mellon nodded: "For example, in the current situation, we cannot lock the victim's last position through blood traces, so we cannot deduce the murderer's movement trajectory, body shape, height, etc. In this case, In fact, it is more cunning than directly using reagents to clean up the blood residue. "
Even with reagents, it may not be possible to completely remove all blood residues.
But it is difficult to find the black spots left before blackening on a piece of paper that is completely blackened.
This is what the murderer was thinking.
"Well, the murderer at least left us a dead dog." Dean was about to ask them to do something that could help: "Guys, please collect the blood from various locations and analyze it. components, surrounding walls, fireplaces, ceilings, etc.”
"Wait!" Mellon interrupted Dean, "You mean there are blood stains on the ceiling, walls, and furnace walls?"
"Yes." Dean pointed to the top of his head: "But it's not very obvious."
Mellon came to where Dean pointed out.
After looking at it for a few times, she shook her head in disappointment: "There are too few reference trajectories, and I can't analyze anything. If there are more reference traces in a few directions, it will be about the same."
Analysis requires data as a reference.
But there was too little data left on site.
After the forensics department collected some samples, they left with the rotting dead dog.
Lawrence hasn't come yet.
Bald Patrolman Hawke has not returned since he left.
Dean was bored and walked to the corner of the fireplace.
There are more than a dozen picture frames hanging on the wall here, arranged in the shape of a heart. At first glance, people feel that this is a loving family of four.
After Dean looked at their photo carefully, a weird smile appeared on his face.
He discovered something very interesting.
In the photo, a man and a woman, who should be brother and sister, are holding hands, looking at the camera with bright smiles on their faces.
On the surface, there seems to be no problem with this scene.
But combined with the eyes of the two parents, it becomes interesting.
Behind the siblings, the male owner's eyes focused on the son's head. The mother's eyes looked at the back of her daughter's head like the male owner.
"Is this because the father doesn't like his son and the mother doesn't like her daughter?" Dean squatted down and scanned the marks around the photo frame.
This photo, compared to the other photos, is so inconsistent.
This time, I found something strange.
In order to maintain this kind of photo frame for a long time, special materials are usually used. After the air inside is removed, all the gaps are sealed with substances such as beeswax.
But the gap at the bottom of the family photo frame in front of me has lost its sealing effect.
Someone opened the photo frame and replaced the photo inside.
Dean stretched out his finger, placed it on the bottom of the photo frame, and gently pulled it.
The photo originally fixed inside, like a tissue, slid down and fell into Dean's palm.
Pick up the photo.
Dean noticed that there was a sentence written in blood on the back of the photo: Behind the sacred, there are lies and filth!
This sentence, coupled with this weird photo, seems to have some kind of hint.
And if you look at these photos closely, it is easy to find that this photo is different from the rest of the photos around it, as if deliberately reminding others that there is a problem here.
"Is this solving a case or solving a puzzle!"
Dean felt that the murderer was sick!
He stuffed the photo back into the photo frame, and then pulled it off completely.
Put away the photo frame.
Dean came to the helper's guest room.
As soon as he opened the door, a strange smell came over.
The guest room is not small, a bit like a single apartment, with a separate bathroom and a TV hanging on the wall.
Under the TV, there is a cabinet with a flashing VCD on it, and a pile of discs on the VCD.
In addition.
There are toilet paper, smelly socks, beer cans and other garbage thrown around.
Dean walked to the VCD, picked up the discs and looked at them carefully.
Most of them are love movies, a few are western cowboy movies, and at the bottom, he also found a love action movie.
"Harry is here, he will definitely like this CD."
Dean smiled and returned to the villa hall without finding anything.
Just then.
Hawke, who had left, finally came back.
He panted and handed two file bags to Dean: "The one above is the basic information of the owner's family, and the other one is the identity information of the helper. You will never guess what his identity was before!"
Thanks to the book friend "National Football Three Brothers" for the two thousand book coins reward, thank you boss.
Ahem~
The speed of the old thief laying eggs is a bit slow~
It's mainly a reader who knows which case the old thief wrote. Although he didn't guess my second creation, he wrote the original case in the comment area.
If I write normally, I won't have any expectations.
I had to rewrite this chapter.
Also, if possible, please don't spoil the story~
Please!
It's a waste of time to change the case outline.
Okay.
Good night, brothers.
