Chapter 187 Key Evidence
Considering what the local police did, Han Xin still decided to wait until he found key evidence before handing it over to the police.

The key evidence is Li Li's "hairpin".

Moreover, Wang Youzhi gave him some good news next.

"Mr. Han, I communicated with the ambassador. The ambassador said that if it is just a forensic doctor, it is completely fine. We can excuse that the local inspection technology is not advanced enough and invite an expert from China." Wang Youzhi smiled.

"In this way, the local police will not dare to falsify the evidence..." Han Xin breathed a sigh of relief.

"Only when the country is strong can we have the right to speak." Wang Youzhi said proudly, and then sighed regretfully: "However, the behavior of the local police really surprised me. If you had invited a forensic expert to come with you to assist in the investigation from the very beginning, They've all been arrested now."

"It doesn't matter." Han Xin said with a smile, "I deliberately released the above evidence to the local police, just to test their attitude. In court, relying on those evidence alone can only prove that he is suspected, and I want to convict him. It is very difficult. I have hidden the really critical mobile phones and murder weapons. Otherwise, if they are allowed to tamper with the key evidence, it will be troublesome."

"So that's how it is..." Wang Youzhi suddenly said, "Wait, did you just say the murder weapon?"

"That's right, Li Li's hairpin, the murder weapon that stabbed both Wu Changjun and the murderer, is the most critical evidence." Han Xin smiled mysteriously, "As long as you find this thing, the case will be closed."

"But this thing will definitely be destroyed?" Zhao Linshan asked puzzled.

Han Xin touched her head and said with a smile: "Although the murderer must have destroyed the murder weapon, his method of destruction was very rough. He probably threw the hairpin out of the window casually. As long as you look carefully, you may be able to find the murder weapon."

"What is the basis of your deduction?" Wang Youzhi asked in astonishment.

"First, the murderer wanted to jump from one balcony to the other. Although the distance between the balconies is not far, they are more than one meter high. It is very difficult to climb up without using hands." Han Xin said, gesturing the height of the balcony railings. "Besides, it's the bloodstain on the balcony of 312. Do you remember? The bloodstain is in the shape of a drop, not a circle."

"Oh!" Zhao Linshan suddenly said, "This shows that the blood did not drip normally, but was thrown up! The murderer threw the murder weapon out at that time! When he waved his hand, the blood splashed on the balcony railing!"

"He didn't throw away the hairpin until he got to Room 312. It must be because he found it inconvenient to hold the hairpin in his hands when he climbed to the balcony of 311. He couldn't put the hairpin in his trouser pocket." Han Xin pretended to be He raised his leg while climbing the railing, "because it would hurt his leg when climbing the railing, and he had to throw it away in the end."

"It does make sense." Wang Youzhi muttered while resting his chin.

Han Xin put down his legs and continued to walk forward: "So the drop of blood in room 313 is definitely the murderer's. It may be that the blood dripped down his arm when he opened the door."

"Then let's find the murder weapon now!" Wang Youzhi said excitedly, "If we find the murder weapon, maybe the experts have come from China!"

So, the three left the local police station and went outside the hotel.

In fact, Han Xin knew exactly where the things were, because the "line of logic" drew a parabola along the drop of blood on the balcony, and then formed a circular area on the green belt outside the hotel.

The hairpin used as the murder weapon must be inside this circle.

"According to the height of the third floor and the shape of the blood drop, I deduce that the thing he threw is in..." Han Xin said as he walked around the area wrapped by the line of logic, "In this area, let's look for it. Bar."

The guidance with logical lines and the vision of the eagle eye made Han Xin sharper when searching for evidence.

After searching for 10 minutes, Han Xin came under a palm tree and pointed to the top of his head.

"Did you see it?" Han Xin pointed to a branch-like thing on the leaf above his head and said, "That's it."

"How do you take it down?" Wang Youzhi murmured to himself, and then kicked the palm tree: it didn't move at all.

"I'll climb up." Han Xin observed the tree and replied.

Coincidentally, he hadn't had the chance to use the ability of "parkour" after learning it, and now this opportunity is coming.

Han Xin retreated a few meters, took a run-up, jumped up and stepped on the trunk of the palm tree, jumped up again, and took the opportunity to reach out and grab the trunk above and hang in mid-air. Stand firm.

"It's almost like playing Assassin's Creed." Han Xin thought to himself, then stood up cautiously.

He always kept the sealed bag on his body to preserve evidence, and it came in handy at this time.He pushed the hairpin into a sealed bag with a leaf and sealed it to ensure that fingerprints would not be wiped off.

Then, Han Xin grabbed the branch under his feet and slowly hung his body on the branch, then let go and fell down.

The moment he fell, he first rolled to remove part of the impact, and then stood up firmly.

"Where did you learn all this?" Zhao Linshan muttered suspiciously.

"I learned it when I was a security guard." Han Xin sucked her mouth, "We have the evidence."

With that said, Han Xin let go of the hairpin in his hand.This is a hairpin decorated with butterflies. From the travel photos taken by the victim's mobile phone, it can be deduced that this is the missing hairpin of the mother Li Li.

As long as you check it, you can find the fingerprints and DNA of the murderer and Wu Changjun on it.

The next step is to wait for experts to fly over from China, "assisting (jian) assisting (du)" the local police to conduct the test.

Before that, Wang Youzhi strongly expressed his admiration for Han Xin.

"Oh my God, I actually found it..." Wang Youzhi looked at the hairpin wrapped in a plastic bag and sighed, "It's like a prophecy. Whatever you say, it will happen."

"The basis of prophecy is reasoning." Han Xin yawned and said, "Logic is also called 'cause and effect'. Everything in this world is connected by the line of cause and effect, and each 'cause' leads to the corresponding 'effect'." .So as long as there is enough information, it is not surprising that it can predict the future. I wonder if you have heard of 'Laplace's Demon', it is similar to that thing."

"Yes, they are indeed very similar." Wang Youzhi replied with a smile, "This afternoon, forensic experts should be able to come from China."

"Just in case, I think it's best to send a few people to follow this expert to protect him." Han Xin muttered.

"Don't worry, our embassy will send a military attache to protect him." Wang Youzhi nodded, "If you and your wife need it, we can also provide you with protection."

"No, I think the murderer is still very confident. After all, all the evidence has been tampered with. He may think that no one will suspect him." Han Xin shrugged, "This is why I didn't put the key evidence before. Another reason to tell the local police, when I confront the killer, I'm going to close the case."

"As expected of my man." Zhao Linshan hugged his arm and smiled.

After tasting a variety of local delicacies, the experts arrived at the airport of Kibb Island at [-]:[-] in the afternoon.

While waiting for the results from the judicial appraisal center, Han Xin also provided the local police with clues from Wu Changjun's mobile phone.

They could not change the WeChat chat records, so the local police had no choice but to bring Shachu Jalen to the police station for DNA sampling and routine interrogation.

Han Xin left Zhao Linshan at the embassy, ​​and then went to the local police station with Wang Youzhi.

This is a rather sturdy man, about 1.8 meters tall, with dark skin, a big back, and a face full of dissatisfaction.But there was a bandage on his right shoulder, which should have been stabbed by Li Li or Wu Changjun.

Shachu's muscles are strong, and the skin on his fists looks very rough. He should have practiced some kind of martial arts.Such a thug was obviously not something Wu Changjun's family of three could handle.

Although Han Xin could not speak the local language, he could understand it, so he knew the contents of the police interrogation clearly.

In the middle section, the police suddenly communicated with Shachu in a low voice, whispering something.

But Han Xin can lip talk besides a master of language, and their whispers are the same to him as talking in his ear.

"We will swap blood samples and fingerprints when we take samples for you, so that the test results will not match..." Han Xin whispered to Sha Chu when he saw the fat man with greasy hair and pink noodles.

At this moment, Han Xin didn't say anything, just waited silently with Wang Youzhi for the end of the interrogation.

At the end, a technician came forward to take a DNA and fingerprint sample for Shatrue.

"You wait for me here for a while." Han Xin told Wang Youzhi, and then came to the door of the interrogation room, waiting for the samplers to come out.

After the opponent came out, Han Xin followed behind him.

After a while, he saw the technician pull out something from his cuff, so he accelerated to catch up with the other person when he turned the corner, and collided with the technician.

The moment the two collided, Han Xin's "Flying Dragon Exploring the Cloud Hand" calmly replaced the two samples that had been switched by the samplers.

The two pairs of samples are exactly the same in appearance, and it is impossible for the other party to find out that the package has been transferred.

"Ouch, Koutuo, Koutuo." Han Xin quickly apologized to the other party, helped him stabilize, then put his hands together and saluted, and hurriedly ran in front of him.

Then, Han Xin and Wang Youzhi gathered at the gate of the police station, ready to go to the judicial appraisal center with the police officers who delivered the samples.The moment he saw Han Xin, the police officer who took the sample was not surprised.After all, the two have the same destination, so it is not surprising that they will collide.

And Han Xin glanced at the sample in the hands of the police officer, and immediately felt relieved.

"I really used all my abilities today." Han Xin sighed and thought to himself.
