Chapter 41-Creating a Future
In the classroom, Chen Fan looked at a group of uniformed police officers and couldn't help but feel a little embarrassed.
Good heavens, this was a little too much.
'I think I shouldn't say it.'
Liu Xi said," Yes, I have to say that some police officers need to be trained. Sometimes, the things these people bring into the laboratory are completely not enough. They let us extract DNA. It can obviously save us trouble, but these people are just trying to make things difficult for us.”
No one dared to refute. This was the strength of the forensic doctor. After all, the case had to go through the forensic doctor in the end.
Chen Fan said," I have written the basic documents very clearly. Let me tell you what I know about the crime scene investigation."”
"There are four things in a crime scene investigation: blood, DNA, fingerprints, and footprints. The footprints have gradually faded, so this is not within my scope of research.”
Chen Fan held the wooden stick in his hand and said,"How do you extract fingerprints like this?"”
Some raised their hands, while others didn't.
Chen Fan looked at everyone's reactions helplessly.
This was simply inconceivable.
Chen Fan took out a cotton swab and a paper cup and said,""You can extract the DNA from the cup.”
A police officer took a cotton swab, wiped it twice, and handed it to Chen Fan.
Chen Fan said helplessly," You can't use the cotton swab directly. You need to dip it in some water. But remember, you can't have too much water. You need to be half-dry and half-moist."”
Everyone looked at Chen Fan in confusion.
"Remember, you have to wrap it with tin foil. After wrapping it with this kind of paper that can absorb water, it will also be helpful when you extract the blood. Our forensic laboratory can't extract it once. Sometimes, in order to obtain accurate evidence, we need to compare it many times.”
Oh my god.
He was really ruthless.
Seeing that everyone still didn't understand, Chen Fan continued,""You guys understand how to pick up girls. This is too dry. It won't do. It's more painful. It won't do even if it's especially wet. It's easy to slip away.”
The crowd laughed, and the girl lowered her head shyly, but she had to admit that Chen Fan was right.
On the other side of the classroom, Jin and Wang Yanan were staring at the situation in front of them. Even Jin, who had seen the world, was shocked.，
Wang Yanan had been running on the streets recently.
Old Jin had his own unique way of dealing with cases, which was to network.
Old Jin knew the location of the crime as soon as possible. He knew how to rush over and how to get there quickly.
Therefore, he brought Wang Yanan back and forth, hoping to teach her his skills.
"Don't ruin the scene. Be careful and see if there's anyone.”
On the other side, Wang Yanan and Old Jin were moving around the house. The doors were pushed open one by one. After making sure that there was no one around, Old Jin heaved a sigh of relief.
"Call Old Huang and inform Chen Fan to come back. There's a case here.”
Wang Yanan nodded.
Soon, police cars arrived and sealed off the scene. Chen Fan arrived late and was shocked when he entered the house.
F * ck.
"What's going on?"
" When Jin and I were patrolling, we found that there was no response from the villa," said Wang Yanan." The garbage at the entrance was too clean, so we decided to go in and take a look."”
" Normally, the garbage truck will come around eight in the morning," said Jin." When we came here, it was noon. Theoretically, there should be garbage at this time, but this one doesn't. I feel that something is wrong."”
Everyone looked at Jin in surprise.
Good heavens, was he that awesome?
"Subtracting the probability of going out, it's very likely that there's a problem here.，”
Criminal Investigation Captain Li, who had followed them, said,"Don't tell me you've been like this for so many years?”
" I'm not very smart," said Jin." I don't know how to reason, so I can only use a stupid method. I know about the Golden Three Heavens. It's helpful to solve the case if we can find the body immediately."”
Chen Fan put on his gloves, took out the box, and began to extract the blood.
After a simple investigation, Chen Fan said," A fatal stab. The other party is obviously here to kill. But there is a problem. You have to be careful. The child is gone."”
A child?
F * ck.
The victim was a woman, and the knife was stabbed into her heart.
There was a pram in the house, but there was no child in the pram.
Then this matter made people's hair stand on end.，
There were two outcomes. The child was kidnapped.
Or perhaps the child was killed by this fellow and thrown somewhere else.
"Get the police dogs and search the area."
Everyone had their own duties.
Chen Fan examined the woman's fingernails carefully and soon extracted some skin tissue from the fingernails.
Then, he copied the fingerprints on the knife and prepared to go back and compare them.
Soon, the child's parents arrived.
The two of them panicked when they saw the scene.
The deceased was not the mistress of the house, but the nanny.
The man was wearing a suit, but his voice was very loud.
"Child, where's my child?"
Old Huang comforted him,"We're still looking for him. He's currently missing."'
The man tried his best to calm himself down. As long as he was missing, it meant that he was not dead.
The woman couldn't hold it in anymore and kept crying.
"I beg you, I beg you, you must find my child.”
The woman was graceful and elegant, but at this moment, she directly knelt on the ground and kowtowed to Old Huang and the others.
Old Huang quickly helped him up and said,"Don't worry, we will definitely help you find it. By the way, do you have any enemies?”
Murder cases were actually very simple.
Husband and wife killed each other. Enemies.
There were very few random killings.
What police officers were most afraid of was random killing. There was no pattern to this thing.
The husband and wife began to think and talk about some business enemies.
In any case, he had to say whatever he could think of. The rest of the investigation was done by the police officers.
"Don't go anywhere. Also, Captain Li, didn't I give you a lesson? Take a cotton swab and wipe it…"
F * ck?
"Where?"
"All of them," said Chen Fan.
F * ck!
You must be crazy.
