Seeing the crime scene flashbacks made me the darling of the police station.

Chapter 50 No Alibi

After meeting Shen Yanzhou, Zhuang Yanzheng delivered a meal to the police station, and then took Su Miaoyi to Club No. 7.

He originally intended to take her back to her residence, but Su Miaoyi wanted to go back to the scene to take another look, so he took Lu Zhishen, who was just about to go home, from the police station, and the three of them went to the scene together.

Bloodstains were found in a private room on the fifth floor of the club, and all the people at the gathering said that only Jiang Lingjie and Xia Yan had been alone together.

Jiang Lingjie is the most suspicious.

They were supposed to take him back to the interrogation room, but he was at the hospital.

Many specific test results are still pending. The hospital's current assessment is that they are unsure if there are any underlying heart conditions and do not recommend leaving the hospital.

So Jiang Lingjie is still in the hospital, and there are police officers specifically monitoring him there.

However, Jiang Lingjie has an alibi.

It was already quite late, but there were still many fans in front of Club No. 7.

The three of them went through the back door again.

When we reached the fifth floor, we pushed open the fifth-floor door.

The door creaked.

Lu Zhishen stared wide-eyed at the door: "Such a big club, you could practically peel a piece of gold off the walls, so why is the door like this, creaking and groaning?"

Su Miaoyi glanced at him: "Are you scared?"

"Aren't you scared? It's late at night, and there's no one around," Lu Zhishen said. "If you speak loudly, there will be an echo. Look at this decor, do you think the three of us are still in our original world? What if, the moment we open that door, we've already been transported to another world?"

Su Miaoyi first looked at Zhuang Yanzheng.

Zhuang Yanzheng acted as if she hadn't heard him speak, and then she looked at Lu Zhishen again.

This was the first time she had ever heard Lu Zhishen speak so much in one breath.

And he didn't seem afraid; he seemed excited.

Su Miaoyi suddenly slowed down, and a few seconds later, she patted Lu Zhishen on the shoulder.

Lu Zhishen suddenly shuddered and turned to look at her.

Su Miaoyi laughed: "You just said all that to scare me, and then you'd frighten me, right?"

Lu Zhishen raised his hand to scratch his cheek, coughed lightly, and continued walking forward.

"Childish." Su Miaoyi snorted, looked around, and although the lights were on, it seemed a bit eerie, so she quickened her pace to catch up with them.

Zhuang Yanzheng observed the crime scene but made no new discoveries.

Lu Zhishen was also looking around.

After a while, Zhuang Yanzheng asked, "Where is Su Miaoyi?"

Lu Zhishen looked around: "I haven't seen her for a while."

"I'm here." Su Miaoyi's voice came from not far away. "The second private room on the east side. Captain Zhuang, I've made a discovery here."

Zhuang Yanzheng and Lu Zhishen immediately went to the private room.

Then Su Miaoyi squatted in front of the cabinet, using tweezers to pull a fishing line out from the gap between the cabinet and the wall.

Zhuang Yanzheng approached.

Su Miaoyi pulled out the fishing line.

Zhuang Yanzheng looked up and saw a very thin fishing line above the window, with the other end in the gap of the cabinet on the other side.

The fishing line is so thin that it's hard to see with the naked eye.

“And that little robot.” Su Miaoyi walked over to the robot and operated it. “I tried this hook here, and it can extend and retract at set intervals.”

"A timer device?" Lu Zhishen asked.

“Yes.” Su Miaoyi shone a flashlight through the window downstairs. “That wooden carving. It must have made a lot of noise falling.” Lu Zhishen looked down, then at the room’s layout and decor: “It does seem to be a decorative piece in this room.”

“The fishing line runs horizontally across the top of the window, and both the fishing line and the load-bearing structure above are very strong. Then one end of the fishing line goes out of the window, is tied to a wooden carving, and is placed on the balcony railing, while the other end is inside the window, controlled by a robot,” Su Miaoyi said. “I checked the robot’s timing records, and it was set to a one-hour timer at 1:02 AM last night.”

“When the time comes, the robot's hook will extend, the fishing line will loosen, and slowly, the wooden carving on the balcony will fall. The window doesn't even need to be opened. Visually, the window will always appear closed, but even a tiny crack is enough to complete the timing device,” Su Miaoyi said. “It also matches the time when the security personnel said they heard noises downstairs and came to check.”

"Is it that amazing?" Lu Zhishen asked in surprise. "The wood carving fell down, but the fishing line was pulled back and hidden in the gap."

Zhuang Yanzheng said, "There is a study on the third floor. Most of the books inside are about mechanical arts and the like, as well as many exquisite things made by Jiang Lingjie."

He had heard some of it as well.

So when he inspected the site in the morning, he paid special attention to whether there were any secret rooms or mechanisms in the venue.

No findings were found.

I didn't expect it to be used here.

“This room protrudes outwards, and the window where the deceased fell is just one room to the west,” Su Miaoyi said. “The security guard saw the body and thought it was the sound of the body falling, so he ignored the wood carving.”

"Didn't the security guards hear anything when the body fell from the building?" Lu Zhishen asked.

“The shift change is between 00:30 and 00:45, and there’s no one here.” Zhuang Yanzheng thought about what the security guard had said, that the shift change was at this time every day. “There was music playing upstairs, and the swimming pool is far away from here. The people having a gathering upstairs only heard the security guard shouting downstairs that someone was jumping off the building, and they didn’t hear anything else.”

"Therefore, the deceased fell between 00:30 and 00:45," Lu Zhishen said. "This device obscured the time of the fall."

“Jiang Lingjie has no alibi. He was there at that time.” Su Miaoyi looked at the shallow marks left by the fishing line on the window.

When she walked to the window, she found that it was not closed properly. After opening it, she found strangulation marks on the window and then found fishing line by following the marks.

Then, slight scratches were also found on the robot's hooks.

“He not only stayed, he also cleaned up the scene.” Su Miaoyi looked at the fishing line she found; this section of fishing line was too long. “There wasn’t a single fingerprint on this robot. The time was set last night, but there wasn’t a single fingerprint. It was also cleaned up.”

Lu Zhishen gave Su Miaoyi a thumbs up.

Zhuang Yanzheng looked at her, nodded, and then went to the exploration kit to get the occult blood blue light reagent.

He remembered that when he saw Jiang Lingjie today, he had an injury on his finger.

However, no traces of his blood were detected at the scene today.

Su Miaoyi looked at what he was holding and raised an eyebrow.

She was just thinking about this when he brought it to her.

The reagent was sprayed onto the fishing line.

“Bloodstains,” Lu Zhishen said.

"Take it back for DNA testing," Su Miaoyi said.

Zhuang Yanzheng also gave her a thumbs up.

Su Miaoyi raised an eyebrow.

Zhuang Yanzheng said, "Let's go downstairs and take a look at that wood carving."

The three people went downstairs.

Because the base of the wooden carving is heavy, if it falls, the base will be on the bottom, and it will just stand there.

There are indeed marks on it from being strangled by fishing line.

"Let's go back and test the DNA in the blood on the fishing line first." Zhuang Yanzheng took a picture of the wood carving.

I received a phone call right after we finished filming.

It belongs to Qi Feng.

As soon as the call connected, Qi Feng said, "Captain Zhuang, Jiang Lingjie died in the hospital."
