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

Chapter 84: Back to the Scene
"What did you find?"

After meeting Wei Lan's parents, Zhuang Yanzheng and Su Miaoyi came to the conference room to meet Yan Cheng.

Yan Cheng said, "I just went back and did another autopsy. Wei Lan has old injuries."

Su Miaoyi's eyes trembled violently.

"There's a very shallow, hard-to-detect teeth mark on the back of her neck, it's been there for at least three weeks," Yan Cheng said.

"Furthermore, according to the examination and test results, last night was probably not the first time Wei Lan was assaulted."

Su Miaoyi closed her eyes and took a deep breath.

Zhuang Yanzheng paused for a moment: "Wei Lan's parents also said that Wei Lan seems to have been acting strangely for the past month."

Yan Cheng remained silent.

Wei Lan is mute and has intellectual disabilities, and the old man is hard of hearing.

It's not impossible that someone could sneak in at night and deceive Wei Lan.

Even if there was some noise, the old man couldn't hear it.

“Let’s go to the scene again.” Zhuang Yanzheng looked at Su Miaoyi. “Let’s go.”

Su Miaoyi immediately followed him.

The two returned to the scene.

As soon as I reached the sixth floor, I saw two people coming down from the seventh floor.

Zhuang Yanzheng had met them at the Municipal Public Security Bureau.

They are the children of the elderly person on the seventh floor.

After leaving the municipal bureau, they went to the hospital to visit the old lady.

"Team Leader Zhuang," the other person greeted.

Zhuang Yanzheng asked, "How is the old lady?"

"He's gone," the man sighed. "We couldn't save him."

The woman turned her head away and wiped away her tears.

Su Miaoyi's lips trembled slightly, and she subconsciously clenched her hands.

Zhuang Yanzheng said, "Please accept my condolences."

The man nodded: "My father spoiled my mother his whole life. My mother probably didn't want to stay here by herself."

Despite the sudden and enormous change, the man appeared calm, but Su Miaoyi felt that he was about to shatter.

After the man finished speaking, he added, "We're leaving now."

Zhuang Yanzheng nodded and moved aside.

After watching them go downstairs, they entered room 601.

Su Miaoyi followed them into the room. She felt a lump in her throat and her mind was in a mess.

She looked at the messy room and took a deep breath to calm herself down.

Zhuang Yanzheng went to the kitchen to look at the knives hidden in the cabinets.

He turned his head and saw Su Miaoyi standing in the living room without moving.

He called her name.

Su Miaoyi snapped out of her daze and went into the kitchen.

Zhuang Yanzheng looked at her again, then hooked the small stool next to him over with his foot, showing her the cabinet above: "Look at these marks."

The cabinets on top looked like they hadn't been used in a long time, covered in a layer of dust.

During the autopsy, Yan Cheng mentioned that Wei Hong had some neck and shoulder problems that did not affect his daily life, but it made it difficult for him to raise his arms.

This cabinet is a bit taller than Su Miaoyi, so she can only reach out to take things from inside.

The old man finds it inconvenient to use, so it might just be left unused.

Su Miaoyi stood on a small stool, looking at the dust marks in the cupboard.

The knife is still on it; it hasn't been removed.

Zhuang Yanzheng removed the knife.

The marks formed under the knife are similar to those on the sides.

Su Miaoyi realized: "The murderer came more than once. Every time he came, he put the knife in this cabinet, which is why these marks were formed."

"What about these longer marks?" Zhuang Yanzheng asked.

Su Miaoyi thought for a moment.

She got off the small stool.

Zhuang Yanzheng put the knife back in its original place in the cabinet.

Su Miaoyi reached out to grab it, but because she wasn't tall enough, her hand touched the hilt and then pulled down, leaving a rather long trail in the dust.

When Wei Hong was young, he wasn't short, so reaching the cabinet wouldn't have been a problem. But now he's old, his back is hunched, he's shorter, and he has an arm injury, making it difficult for him to take the knife down. "The murderer sneaked in one of his raids and forgot to put the knife back in its place after leaving," Su Miaoyi said. "The old man discovered it."

If you cook every day and the knife goes missing, you'll definitely notice.

Zhuang Yanzheng nodded.

Su Miaoyi looked towards the door.

Then they both stood outside the room, and Su Miaoyi closed the door.

Once this type of door is closed, it can only be opened from the inside; it cannot be opened from the outside.

It can only be opened with a key from the outside.

But there is another way.

Zhuang Yanzheng took out his bank card from his wallet and gave it to Su Miaoyi.

Su Miaoyi looked at the black card: "How about we get a different one?"

“This works well,” Zhuang Yanzheng said.

Su Miaoyi didn't say anything more. She slipped the bank card into the crack in the door, gripped it tightly with her fingers, and then swiped it outwards to open the door.

Zhuang Yanzheng raised an eyebrow.

Su Miaoyi looked at Zhuang Yanzheng.

If the door isn't locked from the inside, or if you don't turn the key from the outside, it can be opened with a simple swipe.

Zhuang Yanzheng said, "Now they have special cards for opening these kinds of locks, which are even more effective than bank cards."

Su Miaoyi gave him the card.

Zhuang Yanzheng said, "The locks have not been changed."

That's why he couldn't figure out or connect the dots after seeing the marks on the lock cabinet that morning.

The lock had clearly been pried open with a wire.

Moreover, it was pried open and can no longer be locked from the inside.

In such a situation, if you discover that a stranger has been there, why not change the lock?

Isn't this like leaving the door wide open and waiting for a thief to come in?
He categorized the only way to open the door as picking the lock.

However, if the murderer opened the door with a card the previous times he came, then everything makes sense.

After the old man discovered that someone had come in, he locked the door from the inside.

Once it's locked from the inside, you can't open it with a card.

The only way is to pick the lock.

Su Miaoyi paused for a moment: "Since he discovered that a stranger had entered the room, why didn't he call the police?"

"It's possible that he found nothing was missing from the house, and he probably thought it was just a thief who wouldn't come back if he didn't steal anything," Zhuang Yanzheng said. "Also, he might have thought that locking the door would make it safe."

Su Miaoyi opened her mouth, but couldn't say anything, and didn't know what to say.

After a while, she said, "On a day like today, there's probably no one around the overpass."

With such heavy snow, there's no way anyone will come out to set up stalls.

"Let's go back to the Municipal Bureau first," Zhuang Yanzheng said. "The New Year is almost here, and even thieves want to celebrate."

Therefore, theft cases increase every year-end.

Su Miaoyi listened to his words.

These kinds of cases are numerous and difficult to solve.

Zhuang Yanzheng said, "Recently, some branch offices and police stations have arrested some thieves. Qi Feng has already taken people to question them."

Su Miaoyi nodded.

The murderer was a habitual thief.

There are also gangs that steal things.

It's quite possible that they know each other.

Moreover, the tattoos on the killer's face should leave a deep impression on those who have met him.

Su Miaoyi looked at the snow outside the window.

Still raining.

The snowflakes were large but not fast-moving; they weren't falling wildly. But at that moment, Su Miaoyi had no mood to appreciate their beauty.

"Are you feeling unwell?" Zhuang Yanzheng asked, glancing at her.

"A little bit," Su Miaoyi said, looking out the window. "Four lives lost in a day and a night. Maybe it's because the New Year is approaching, and people are thinking about going home for a family reunion dinner. This feeling has suddenly been amplified."

"What we can do is seek justice for the deceased, eradicate evil from society, and prevent, stop, and reduce illegal and criminal activities," Zhuang Yanzheng said.

Su Miaoyi nodded.
