Chapter 42

Several forensic doctors returned to their posts. Here, Old Zhou took a sip of hot tea, calmed down, and said, "To be honest, this kind of thing is really hard to handle."

In the observation room, Old Zhou complained.

Teacher He said, "Then those fingerprint comparisons seem to have lost their meaning."

"It's just meaningless, but since it was done, it's useful. Fingerprint comparison, entering the fingerprint comparison library, basically every forensic doctor must understand the idea of 'I for everyone' in the first class."

The lawyer nodded, expressing praise.

Bai Lu said, "Is it that if everyone compares in the future, it can also be used?"

"That's right. Today we compare, maybe it's useless, but what about the future? What if we find our fingerprints here during comparison? These are all things accumulated by various forensic doctors. Moreover, the criminal investigation department is also doing this. Everyone develops the habit of collecting fingerprints. When the database is large, you won't be able to run away."

So scary.

However, if no one does it, the database will never be created. But if everyone insists on it tacitly, then the future database will only get bigger and bigger.

The efficiency of solving cases will also really increase a lot.

"A brush sweeping the world is something basically prepared by all criminal investigation departments."

Chen Fan said with disdain, "What's the use of a brush? Ultraviolet rays, acetone, and these things are better, right? Add some ethanol, and the fingerprints will only be clearer."

Old Zhou was stunned and said, "Say that again..."

"Useless, too expensive, high cost. Powder and such are the cheapest. Mine has too high a cost, useless. However, fuming is okay."

Good guy, how come he has this kind of strange knowledge?

"You, Chen Fan, I feel more and more that you always come up with some strange ideas in some useless places."

Bai Lu said, "Useful or not?"

"Useless, because the cost is high. But what Chen Fan said is really the best for scanning fingerprints. For example, ultraviolet rays are the clearest, but who carries an ultraviolet lamp with them every day?"

Here, Li Tian entered the room and said, "Do you want to record the interrogation footage?"

Can this be recorded?

"Are you sure it's not against the rules?"

"Small matter. No show today, I'll give you a big show, just interrogation."

Chen Fan said, "Then what if you can't interrogate anything?"

"I won't be able to?"

In the interrogation room, Li Tian slammed the table and roared, "Those things in your room, chemical products, how do you explain them?"

"I just wanted to research it myself, isn't that allowed? This isn't illegal, right?"

"Why did you appear at the scene?"

"Just wandering around."

Li Tian was silent.

Damn, really can't interrogate anything.

The audience watching had a headache. What should be done?

And at this time, in the observation room, the lawyer said, "I've heard of this kind of thing. As long as the psychological defense line isn't broken, it's useless. This person has excellent psychological quality. After carefully planning for so many years, she must have thought of all the escape routes."

Teacher He said, "Locked the heart door, right?"

"Yes, this kind of person, if she refuses to admit it, the case can't be determined. The chat records of the dead people are all gone. These people have no evidence at all. If she refuses to admit it, it can only be proven from the side. But only chemical products were found, no finished products, which shows she was prepared to be caught."

At the scene, Li Tian walked out, speechless.

"Still filming?"

"This guy is a bit hard to chew."

Chen Fan said speechlessly, "Then don't show off. Really, embarrassed now, right?"

"What's embarrassing? Interrogation is just like this. Let her be, plenty of time, play slowly. This guy is definitely the murderer, but there is no evidence. This woman seems to reject the outside world."

Chen Fan pondered for a moment and said, "I do have a way. Let me interrogate, I can handle it."

"Not illegal?"

"Not illegal. Remember, she is a woman, I am a handsome star, did you forget?"

Damn it, Li Tian got angry, stared at Chen Fan, and said, "Are you sure?"

"Look down on me? As long as it's a woman, there is no one who doesn't like me."

Chen Fan walked in and looked at the woman in front of him.

Her face was average, her body was a bit fat, and the wisdom in her eyes couldn't be hidden.

The woman looked at Chen Fan and said, "I'm watching the livestream, you are also here to help, right?"

Chen Fan thought silently in his heart.

A voice appeared in his mind.

"This world is broken. I hate everything, I hate him, I hate everything."

Chen Fan frowned, looked at the woman, and said, "You like him?"

The woman was stunned for a long time and said, "How did you know?"

"Nothing, just curious. Normally, no one would like you. It must be you liking someone else. Sorry, I'm an appearance-focused person. I can't look at your appearance."

The woman instantly got angry, stood up, and wanted to grab Chen Fan.

Chen Fan continued, "I also learned some reasoning. I'm thinking, you should like him, and then, he told you, 'Actually we are just playing,' and then told you, 'Don't say anything outside,' saying it's an underground romance."

"What about these? You want to say, he was just lonely and used me, right? I know this, I know it myself. You want to use these words to stimulate me? Save it."

Chen Fan said silently, "Actually, he likes you, didn't you know?"

"Lying, wouldn't even find a better reason."

"Those drugs in your room, actually you wanted to research drugs to treat heart disease, but you researched 'unknown poison', which is why it couldn't be found."

The woman’s voice became smaller, and her eyes dimmed.

"I want to hear your story. If you are willing to say it, say it. If you are not willing, forget it."

The woman chuckled and said, "Actually, not every heart disease patient is worth being sympathized with."
