Lin Xinyi gave the answer.

Everyone also restored the full picture of this case in their minds:

About three hours ago, the deceased drowned and his body floated directly to the water because of its obesity. It had been soaked in the river at night and had not been discovered by anyone.

Ten minutes ago, the body accidentally collided with a passing cruise ship and was sucked into the propeller.

The huge force of the propeller chopped the corpse into several pieces, leaving a large number of messy slashing scars on the corpse.

During this process, the corpse also rotated at high speed with the propeller, scratching the hull many times, causing a large area of ​​skin to peel off.

After that, the cruise ship continued to move forward, and the body that was broken into pieces was left in the waters.

As the body was broken into pieces, a large amount of blood was lost and dyed the river red. Finally, Kudo Shinichi and Mao Lilan who were passing by witnessed the shocking blood wave phenomenon.

"So that's it."

"Because of a simple accident, the case became complicated on the surface."

The Mumu Police Department, who knew the truth, couldn't help but feel sad about this.

The truth behind the accidental dismemberment of the propeller actually sounds a bit bizarre.

But no one present, including Kudo Shinichi, could question Lin Shinichi's conclusion.

Because everything he said was backed by evidence.

As Lin Xinyi said himself, what he did was not reasoning, but just helping the deceased speak out his words.

"Wait..." After sighing for a while, the Mumu Police Department suddenly noticed another problem: "These evidences can only prove that the deceased died of drowning and was accidentally involved in the propeller. It cannot prove that she committed suicide.

"

"Brother Lin."

He changed his title very familiarly:

"Why did you determine that the deceased died of suicide in the first place?"

"Well..."

"The clue that the deceased committed suicide is found in the waist and abdomen of the body."

"Detective Kudo should have noticed this, right?"

Lin Xinyi gave Kudo Shinichi a meaningful look:

He had noticed before that the young detective focused on the waist and abdomen of the deceased as soon as he saw the body parts.

It was obvious that Kudo Shinichi also noticed the details on this corpse.

"That's right."

Kudo Shinichi nodded and explained under Lin Shinyi's gaze:

"I noticed from the beginning that there was an obvious strangulation mark caused by rope binding on the waist and abdomen of the deceased."

"Did the murderer tie up the deceased?"

Officer Memu subconsciously made a guess.

"No, this was probably tied by the deceased himself."

Lin Xinyi slowly denied it:

"Because on the wrist of the deceased - although only one hand has been fished out so far, we can still see that there are no rope marks on the wrist of the deceased."

"Only the waist is tied, but the hands can still move freely..."

"If this was a homicide and the rope was tied by the murderer, would he have left a pair of hands that could move freely to the deceased?"

"Had the hands been free to move, the victim would have been able to untie the rope himself after being pushed into the water."

"So, there is often only one situation that can cause such rope marks..."

He paused slightly here.

The famous detective named Kudo Shinichi picked up the conversation very tacitly:

"It was suicide by diving."

"People who commit suicide by diving often tie heavy objects around their waists so that they cannot surface after entering the water."

"So there will be rope marks on their waists, but there will be no signs of being tied up on their wrists."

"The deceased only had rope marks on his waist, and he died of drowning. This is probably a case of suicide by drowning."

Kudo Shinichi methodically restored the scene:

"I speculate that the deceased went into the water with a heavy object tied around his waist and drowned."

"And within the next three hours, the rope loop tied around the waist gradually loosened under the impact of the river water, and the body was freed from the heavy objects and floated to the surface."

"This is the whole truth about this case."

Kudo reconstructed the scene based on reasoning and made a conclusion on the case.

Lin Xinyi, on the other hand, chose his words very carefully out of professional habits:

"It's hard to say it's a final conclusion. After all, I only have the conditions to do a corpse surface test, and I can't completely rule out other possibilities."

"But judging from the evidence that can be collected so far, the deceased most likely died of suicide."

"Next, please send frogmen into the water to search carefully. You should be able to find the ropes and heavy objects left by the deceased at the bottom of the river."

"At the same time, the police need to confirm the identity of the deceased as soon as possible and confirm whether the deceased had any motive for suicide through interviews and investigations."

"If possible, a full-body autopsy must be performed to confirm that the deceased had no subcutaneous bleeding caused by trauma before death."

"I see!"

Sheriff Memu breathed a long sigh of relief:

Although Lin Xinyi always left room for words, he could still tell that the case was basically stable:

"It turns out the truth is that simple!"

There is no murderer in this case.

With the casual reasoning of two "new ones", Lin Shinichi and Kudo Shinichi, a mutilated corpse case with a bad social impact and huge handling pressure was solved so easily.

Thinking of this, all the police officers present became as relieved as the Memu Police Department.

But Kudo Shinichi, who had just solved a major case, fell into deep thought.

"Yes, the truth is that simple..."

"A boat, a propeller, a simple accident."

"Why didn't I think of that?"

This answer is actually not difficult for the famous detective Kudo Shinichi.

If he was given more time to think, he should be able to see through the truth hidden behind it.

But, no matter what...

This time he was completely left behind by Lin Xinyi.

Lin Shinichi had already seen through everything when he was struggling. It was obvious that he, Kudo Shinichi, was defeated in this duel between detectives.

Speaking of which, this seems to be the first time he has lost in such a detective duel, right?

Raising his head, Kudo Shinichi's eyes towards Lin Shinichi had changed.

The look in his eyes showed unwillingness, but also respect and admiration:

"Mr. Lin Xinyi, are you also a detective?"

"No."

Lin Xinyi shook his head decisively:

"I'm not the famous detective you imagined, and I'm not much smarter than ordinary people."

"You are a step behind me just because you lack some knowledge and experience."

Although he has participated in the detection of many cases, including some major ones, Lin Xinyi has never regarded himself as the kind of wise and almost evil detective in novels.

Because programmers know programming, architects know design, mathematicians are good at calculations... Autopsy is just a common job skill for Lin Xinyi.

He is good at this not because he has a higher IQ than ordinary people, but because he spends more time and energy studying than ordinary people.

"indeed..."

Kudo Shinichi nodded thoughtfully:

"I'm better at starting with on-site clues other than corpses. Wound trace examination is not my strong point."

"If I could understand a little more, maybe I could see the truth as soon as you did."

For a high school student, Kudo Shinichi's knowledge is actually beyond imagination.

Because he had an incredible father, and his father took him to an incredible technical school in Hawaii.
