"If we can extract footprints on the balcony wall and guardrail handrails, they are probably those of the murderer."

Forensic doctors not only need to study corpses, but also know how to detect traces, analyze scenes, restore the facts of the case, and profile criminals.

An old forensic doctor with sufficient practical experience can almost be said to be the king of understanding in the criminal investigation world.

Therefore, even if nothing was found on the body, Lin Xinyi could still deduce the incident of the crime in a coherent manner.

"I see..."

The police officers in the Forensic Division all looked as if they were suddenly enlightened.

However, the next second, they poured cold water on Lin Xinyi again:

"But, we've also seen it from the balcony..."

"There are indeed no fingerprints or footprints there!"

Lin Xinyi: "..."

He could already smell something bad.

It feels like the assistant I met during the autopsy was Komatsu...

"Um..." Lin Xinyi asked tentatively: "What method did you use to find fingerprints and footprints?"

"Method? Several young police officers looked at each other in confusion: "There is no way...just use your eyes."

"Just see it with the naked eye?"

"Have you always seen only with your eyes?"

Lin Xinyi's expression suddenly became extremely exciting.

"Yes, what else?" the police officers replied matter-of-factly.

"What about blue light, purple light, and multi-band light sources?"

The blue light is used to find sweat fingerprints, the purple light is used to find mineral oil fingerprints, and the multi-band light source is more versatile. It can find oil fingerprints and sweat fingerprints that are difficult to distinguish with the naked eye on various smooth objects such as paper, wall coverings, imitations, etc.

.

Although these devices should not be used in this case, Lin Xinyi still asked first.

Because these are the most commonly used and basic equipment in on-site surveys.

However, the response of these police officers from the forensic field investigation department was: "None of these..."

"..." Lin Xinyi was silent for a while and then asked:

"Are there any thiocyanic acid and potassium thiocyanate?"

"Where's the alizarin ethanol solution?"

These three are common chemicals used to reveal potential dust fingerprints.

"Ninhydrin solution, silver nitrate solution, are they available?"

These two are common chemicals used to reveal latent sweat fingerprints.

But this time, the reaction of these young police officers was:

"????"

They have simply never heard of these awkward chemical terms.

"never mind...."

"502 glue, you should have this, right?"

The 502 glue display method is suitable for displaying potential sweat fingerprints on almost all non-permeable bodies.

Lin Xinyi doesn't want to investigate the case now, he just wants to see how lacking the basic investigation equipment is in this forensic class.

"502 glue?"

Sure enough, these young police officers looked confused:

"Is this also related to the on-site investigation work?"

"you..."

Lin Xinyi choked hard:

"How come your on-site investigation department doesn't have anything?"

"Then what exactly did you investigate?"

Even the most basic investigation equipment is not equipped. No wonder they have successfully controlled the suspect, but they still have to call in foreign aid.

Otherwise, if the police can find traces scientifically and effectively, why would there be a need for detectives in this case?

Thinking about it this way, the person who was cooperating with the Metropolitan Police Department was not the search class at all, but was held back by your forensics class!

"etc..."

Lin Xin reacted instantly.

He turned his head and looked at the Memu Police Department with a look of resentment:
Chapter completed!
