Chapter 72: The Door to Your Heart Is Locked

? (Please support, sixth update)

A few forensic doctors returned to their posts. Over here, Old Zhou took a sip of hot tea, collected himself, and said, "Honestly, this kind of thing is really hard to handle."

In the observation room, Old Zhou was grumbling.

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

"Exactly, no meaning. But since we did it, it's useful. Fingerprint comparison, entering it into the fingerprint database—basically every forensic doctor's first class has to understand this idea of 'I for everyone.'"

The lawyer nodded, showing approval.

Bai Lu said, "What if, in the future, when everyone does comparisons, it can be used too?"

"Exactly. Today our comparison might be useless, but what about the future? What if during a comparison, they find fingerprints from our side? These are things every forensic doctor gradually accumulates. And this thing, the criminal investigation team is doing it too. Everyone develops the habit of collecting fingerprints. When the time comes and the database is big, you won't be able to run even if you wanted to."

How scary.

But if no one does it, then the database will never be built. But if everyone silently persists, then in the future the database will only get bigger and bigger.

The efficiency of solving cases will really increase a lot.

"A brush, sweeping the world, is something basically every criminal investigation team keeps on hand."

Chen Fan said disdainfully, "What's the use of a brush? Ultraviolet light, ninhydrin—aren't those better? Paired with some ethanol, the fingerprints will only be clearer."

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

"Useless, too expensive, the cost is too high. Powder and stuff are the cheapest. Mine, the cost is too high, useless. But fuming could work."

Good lord, where did this kind of strange knowledge come from?

"You, Chen Fan, I'm now increasingly feeling that in some useless places, you can always come up with some strange thoughts."

Bai Lu said, "Is it useful or not?"

"Not useful, because the cost is high. But what Chen Fan said really is the best for scanning fingerprints. For example, ultraviolet light, the clearest and all that. But who carries an ultraviolet lamp around with them every day for no reason?"

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

This can be recorded?

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

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

Chen Fan said, "What if you don't get anything out of the interrogation?"

"Me, not able to do it?"

……

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

"I just wanted to do my own research, is that not allowed? That's not illegal, right?"

"Why did you appear at the scene?"

"Just wandering around."

Li Tian fell silent.

Damn, he really couldn't get anything out of the interrogation.

The audience watching was getting a headache. What are we going to do?

And at this moment, in the observation room, the lawyer said, "This kind, I've heard of it. As long as the psychological defense isn't broken, it's useless. This person's psychological quality is very good. After so many years of careful planning, she must have thought of every escape route."

Teacher He said, "The door to her heart is locked, right?"

'Yes, a person like this, if she refuses to admit it no matter what, the case can't be confirmed. The dead person's chat records are all gone. These people, not a single piece of evidence. She refuses to admit it no matter what, so we can only prove it indirectly. But we only found chemical products, not finished products, which means she was prepared to be caught.'

On the scene, Li Tian walked out, his face full of exasperation.

"Still filming?"

"This one is a bit tough to crack."

Chen Fan said speechlessly, "Then stop showing off. Really, embarrassing, right?"

"What's there to be embarrassed about? Interrogation is just like this. Leave her hanging, plenty of time, take it slow. This one is definitely the murderer, just no evidence. This woman, it's like she rejects the outside world."

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

"Not illegal?"

"Not illegal. Remember, she's a woman, I'm a handsome star. You forgot?"

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

"Looking down on me? As long as it's a woman, there's none that doesn't like me."

Chen Fan walked in and looked at the woman before him.

Average face, a bit of an overweight body, the intelligence in her eyes couldn't be hidden.

The woman looked at Chen Fan and said, "I'm watching the livestream. You're here to help too, right?"

Chen Fan thought silently to himself.

A voice appeared in his mind.

"This world is broken. I hate everyone. I hate him. I hate everything, 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, so it can only be that you like someone else. Sorry, I'm a looks person. With your looks, I can't keep watching."

The woman instantly flared up, stood up, and tried to grab Chen Fan.

Chen Fan continued, "Let me try some reasoning too. I figured, you should like him, and then, he told you, actually we're just having fun, then told you, you can't say anything outside, said it was some kind of underground romance."

"So what? You want to say he was just lonely and used me. I know this, I'm clear about it myself. You want to use these words to provoke me? Save it."

Chen Fan said quietly, "Actually, he liked you. Didn't you know?"

"Lying, you can't even come up with a better excuse."

"The medicines in your room — actually, you wanted to research drugs to treat heart disease, didn't you? But what you ended up researching was a nameless poison, and that's why it couldn't be found."

The woman's voice grew softer, and the light faded from her eyes.

"I want to hear your story. If you're willing to tell it, then tell it; if not, then forget it."

The woman laughed softly and said, "Actually, not every heart-disease patient is worth sympathizing."
