Forensic doctor: I only love dissecting corpses and idolizing Hannibal

Chapter 41: Wipe out a future (please support, sixth update)

In the classroom, Chen Fan looked at a group of police officers in uniforms, and he couldn’t help but feel a little bit different.

Boy, is this a bit too much?。

‘I think I’d better not say anything. Liu Xi said: ”

I must say that some police officers must be trained. Sometimes the things these people bring into the laboratory are simply not good enough. Let us extract DNA. It can obviously save trouble. These people are here to give us It’s a stumbling block.”

No one dared to refute, this is the strength of the forensic doctor, after all, the case must go through the forensic doctor in the end.

Chen Fan said: “I actually wrote the basic documents very clearly. Let me tell you what I know about on-site inspection.。”

“On-site investigation actually consists of four things: blood, DNA material, fingerprints, and footprints. The footprints have gradually faded, so this is not within the scope of my research, so I said I can extract fingerprints.

Chen Fan held the wooden stick in his hand and said, “How do you extract fingerprints like this? ” ”

Some people raised their hands, and some didn’t.

Chen Fan was helpless, watching everyone’s answers and reactions.

This was simply unbelievable.

Chen Fan took out a cotton swab, a paper cup, and said, “Extract the DNA from the rim of the cup. ”

A police officer took a cotton swab, wiped it twice, and handed it to Chen Fan.

Chen Fan had no choice but to say: “The cotton swab cannot be wiped directly. You need to dip it in some water, but remember, don’t use too much water. It is only suitable for semi-dry and semi-moist conditions. ”

Everyone looked at Chen Fan in confusion.。

“Remember, you also need to wrap it with tinfoil. This kind of paper that can absorb moisture will also be helpful when you extract blood. It is impossible for our forensic laboratory to extract blood once. Sometimes for the accuracy of the evidence, multiple extractions are needed. For this comparison, the more careful you are, the less effort we will put in, and the documents will be produced the fastest when the time comes. ”

Oh my god.

It’s really cruel.

Seeing that everyone still didn’t understand, Chen Fan continued: “You understand, when it comes to picking up girls, this is too dry, it will hurt, and it won’t work if it is extremely wet. It will slip away easily. Only when it is just right can it be done. Can. ”

Everyone in the audience laughed wildly, while the girl lowered her head shyly, but she had to admit that Chen Fan was right. What

was different from the class in the classroom was that on the other side, Lao Jin and Wang Yanan stared at the situation in front of them. , Lao Jin, who had seen the market, was also scared. ,

Wang Yanan has been running around the streets recently.

Lao Jin has his own unique way of handling cases, which is connections.

After running on the streets for many years, Lao Jin can know the location of the crime the fastest. How to rush there, how to go quickly.

So running back and forth with Wang Yanan is also hoping to teach this girl his skills。

“Don’t damage the scene, be careful and check to see if anyone is there. ”

Here Wang Yanan and Lao Jin moved little by little in the room, opening the doors one by one. After confirming that no one was there, Lao Jin breathed a sigh of relief.。

“Call Lao Huang and notify Chen Fan to come back. There is a case here. ”

Wang Yanan nodded.

Soon, police cars arrived one after another a

he was also shocked. Holy shit。

“what’s the situation? ”

Wang Yanan said: “When Lao Jin and I were patrolling, we found that no one responded to the villa here, and the garbage at the door was too clean, so we planned to go in and take a look. ”

Lao Jin said: “Generally, the garbage truck will come at around eight o’clock in the morning, but when we came here, it was twelve o’clock at noon. At this time, theoretically, garbage will be produced, but this house does not, I feel Something is wrong. ”

Everyone looked at Lao Jin in surprise.

Good guy, are you so awesome?

“Excluding the possibility of going out, it is very likely that there is a problem here.。，”

Captain Li, the detective who followed, said, “You can’t, have you been like this for so many years?”

Lao Jin said, “I don’t have a bright mind and can’t reason, so I can only do stupid things. I still know it during the golden three days. Being able to discover the body immediately will help solve the case.”

Chen Fan put on his gloves, took out the box, and began to extract blood.

After a simple investigation, Chen Fan said: “One knife kills. The other party is obviously here to kill people, but there is a problem. You should pay attention. The child is gone.” Child

?

Depend on.

The deceased was a woman, and the knife was inserted into her heart.

There is a stroller in the house, but there is no child in the stroller.

Then this thing is creepy. ,

two results, the child was kidnapped.

Or, the child was killed by this guy and is still somewhere else。

“Get on the police dog and search the area. ”

Everyone performed their duties.

Chen Fan checked the woman’s fingernails, looked through them carefully, and quickly extracted a little skin tissue from the nails.

Then he rubbed the fingerprints on the knife and prepared Go back and compare.

Soon, the child’s parents arrived.

They panicked when they saw the scene.

The deceased was not the hostess of the house, but the nanny.

The male host was wearing a suit, but his voice was loud。

“Child, where is my child. ”

Lao Huang comforted and said: ‘We are still looking, and we are currently missing.’

The man tried his best to calm down his emotions. As long as he is missing, it means he is not dead.

The woman couldn’t stand it anymore and kept crying.。

“Please, I beg you, must find my child. ”

The woman was graceful and luxurious, but she knelt down on the ground and kowtowed to Lao Huang and the others.

Lao 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? ”

The murder case is actually very simple.

Husband and wife kill each other, enemies.

Very few random killings.

What the police are most afraid of is random killings. There is no pattern in this thing.

The couple began to think about it and talked about some business matters. Enemies and so on.

Anyway, I have to mention everything I can think of. The remaining investigation work is done by the police.。

“Don’t wander around. Besides, Captain Li, didn’t I give you a lesson? Take a cotton swab and wipe it……”

wipe?

“Where to wipe?

Chen Fan said: “Everything. ” ”

Holy shit,

you’re crazy.
