Police officer Chen Shu

Chapter 791 Complete Logical Reasoning
Chen Shu got up, opened all the windows with a whoosh, and leaned out to look down at the building below.

This is a small path behind the hotel, with a long strip of muddy grass laid along the wall of the main building. Although it is daytime, there is not a single person in sight.

The dirt on the curtains should be from the muddy grass downstairs, but why did it end up on the curtains?

Zheng Jie, who lives upstairs, has an alibi.
The deceased who lived downstairs. Disguised shoe prints.
Curtains upstairs, muddy grass downstairs
Upstairs and downstairs

The Second Rope That Disappeared
Chen Shu kept retracing his thoughts, trying to verify his previous assumptions.

After a moment, he confirmed the feasibility of the hypothesis.

Chen Shu's gaze remained calm as he gripped the thick rope in his hand. He said, "I now know how Zheng Jie escaped the scene and disposed of the rope that should have been left in the house, as well as the ridiculous alibi he fabricated."

hiss!
Upon hearing Chen Shu's confident voice, the air in the room froze, and everyone's eyes were fixed on him.

The lead investigator in the murder case, Huang Mao, was speechless; his lips trembled slightly, but he couldn't utter a sound.

He Chengfeng, who had just finished making the phone call and entered the room, suppressed his excitement, feeling that this time it really could work.

Chen Shu walked quickly to the door, reached out and grasped the handle, turned the doorknob and opened it, then turned back and said, "Let's go downstairs."

The group arrived at a small path behind the main building of the hotel.

Chen Shu placed the chair he had casually brought over from the roadside on the roadside, stood on it, and scanned the corner of the wall with a superior gaze. Everyone followed his gaze.

The lawn that stretches along the corner of the building is lush and full of life.

There was only one small patch of grass with obvious, repeated trampling marks. Following those marks to the wall, everyone looked up again.

Oh! What a coincidence! Right above us is the window of the room where the crime occurred!
The group stood by the roadside, looking up at the high wall in a gesture of respect.

If it weren't for the bright sunshine, these men, with their large physiques and menacing appearances, might have been mistaken for a group of thieves and pinned to the ground by the hotel security.

“There are trampling marks in the grass around here.” Standing on the chair, Chen Shu had a much clearer view than the others. He pointed to a spot near the corner of the wall and said confidently.

Chen Shu continued, "Hey, if I'm not mistaken, Zheng Jie probably did it this way. First, he booked a room at the hotel, a room located above the deceased's. To get a clear location, Zheng Jie's booking time must have been later than the deceased's."

"The second step was that he tied a rope that had been hanging outside the wall to his room, extending all the way to the ground. There were few people around, and at night there were hardly any lights, so no one would notice."

"Then he left the hotel openly and went to a bar. At the bar, he drank with his friends and the deceased until night, then put the deceased in a taxi and returned to the bar to continue drinking with his friends."

“During this process, he must have taken the opportunity to run back to the hotel’s back door. He could have made up any excuse. I guess he would have gone to the toilet because he had an upset stomach, which would have required some time and a small space to lock the door.”

Chen Shu looked down at He Dadu and asked with a smile, "I don't know where he's drinking tonight, but it must be very close to here."

"The bar is on the street next door. Let me see how long it will take to get there." Having recently developed a good habit, Huang Mao immediately took out his phone, opened a map navigation app, and started tapping away rapidly after receiving Chen Shu's instructions.

The crowd waited quietly, the atmosphere somewhat like the lottery draw at 7:30 pm after the TV news had ended.

Anticipation filled me, and I slowly held my breath.

"Hmm, there's a river ahead, we have to go around the bridge. Hmm, wait a minute, Chen Da, that'll take more than half an hour round trip, there's just not enough time!"

Chen Shu looked at the alley outside the guardrail and chuckled, "There might be a traffic jam now, or you could try switching to 'walking mode' and see."

"Let me try... Hmm, that's not right either, it still takes more than half an hour... Wait!" Huang Mao stared at his phone screen, then suddenly realized something and exclaimed excitedly, "Haha, how could Zheng Jie possibly walk over so leisurely! Hmm, I'll switch to 'cycling mode' right away... Hey, only seven minutes! Fourteen minutes round trip!"

“It’s the middle of the night. Switching to a high-powered electric motorcycle would probably shorten the time.” Chen Shu stopped looking at the alley and turned around to look up at the building. “Hmm… I remember Zheng Jie owns a motorcycle. We can go look for it. It might be the vehicle involved in the case.”

He Chengfeng nodded slightly, a hint of admiration flashing in his eyes. The other party's reasoning was very logical, and his grasp of details was very precise. Each link was connected to the next, leaving no screw unattended, gradually making the truth of the matter clear.

Chen Shu pointed to the outer wall and continued, "After returning here, he used the rope he had thrown out of his room earlier to climb up to the third floor, kill the man, and then disguise himself. After the incident, he climbed down the rope again and headed to the bar."

"He then continued drinking with his friends until the timeframe for the victim's death was exceeded, and then, openly and under surveillance, returned to his hotel room. Finally, before dawn, he retrieved the rope tied outside the window."

He Chengfeng picked up where Chen Shu left off, and said with a hint of excitement, "And Zheng Jie's mother, Zheng Amei, a cleaner at the hotel, entered the crime scene the next day under the pretext of cleaning the room."

"Since Zheng Jie has already taken the rope, all she needs to do is lock the window that Zheng Jie opened. And this simple action only takes four seconds!"

Chen Shu nodded, jumped off the chair, and concluded, "In this way, the entire case has completed a theoretical closed loop."

"Then, where is the evidence?"

"Motorcycle, second rope, window sill in bar toilet."

Chen Shu rested his right hand on the chair, looked at the railing on the other side, pointed at them and laughed: "It hasn't rained recently, so there might still be Zheng Jie's fingerprints on them. Scan them all, and we'll probably find something."

"Since it can be hung outside the window, the rope that Zheng Jie retrieved must be very long, and it wouldn't be easy to hide it on his person and take it away."

“You can’t burn things in the hotel room, so by following the surveillance footage and watching Zheng Jie leave the room, you can always find clues.”

"And then there are motorcycles with license plates. These things are big, and it's not easy to steal or burn them in the city."

"And the windows of the bar's restroom and the hotel railings, which were places Zheng Jie had to climb, must have left traces of the other party."

"In just half an hour, Zheng Jie had neither the time nor the energy to spend on these details."

He Chengfeng nodded, his thoughts were clear, and everything else would fall into place naturally. Just as he was about to leave, Chen Shu stopped him.

Chen Shu chuckled and said, "I suddenly thought of something else."

He pointed to the hotel's exterior wall and said, "The person has already been taken inside. They can either wear their shoes or leave them in their rented room. Even the most cautious person wouldn't be so careful about this."

He Chengfeng's eyes lit up; he knew this was direct evidence.

Unless one has received professional training, the footprints left on the wall and windowsill would be unmistakable if an ordinary person used a thick rope to climb the wall.

Especially since both locations are outdoors, and the floors where the incidents occurred are not high, they are constantly exposed to wind and sand, and unless it rains, they are covered in a thick layer of dust.

Shoe prints, of course, can be scanned accurately with a single stroke.

"And the windows near the bar's restrooms, we need to check those too." Chen Shu was in a good mood, as if he had solved his own case, and spoke quickly. "Of course, if Zheng Jie really did sneak out from there."

"The bar has surveillance cameras at both the front and back doors. If he wants to slip away unnoticed, he can only do so through the restroom. There's no way he can escape from there! I'll send people to the bar right now!"

He Chengfeng, who had been waiting so long that the flowers had all withered, waved his phone in one hand, feeling full of energy, and couldn't wait to go back and have another showdown with that guy who was prepared to give no confession.

He looked like a director who had a deep discussion about life with the female lead the night before, and now that he had the producer's money, he was eager to get started, both tired and excited.

"Thank you, Officer Chen! Once I've solved the case, I'll definitely treat you to mushrooms!"

Having gotten the answer, He Chengfeng hurriedly left with Huang Mao.
