As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

Ye Lin opened it and looked around, then slammed it shut, "Captain Li, I need to go to the scene again tonight."

"Oh, go ahead, go ahead, we have someone here." Li was a little confused.

Ye Lin wanted to verify something.

......

On June 6, at night, at 16 o'clock in the evening, Ye Lin rushed to Room 7, Unit 1, Building 402, Lanyuan District , which was Niu Xiaowei's home. He wanted to verify some things.

The police officer guarding the scene had received a notification from Chief Li. When he saw Ye Lin coming, he quickly opened the door and turned on the lights.

"No need to turn on the light, I'll see for myself."

Ye Lin walked in and closed the door. There were street lights on the roads in the community, but they could not illuminate the living room. Perhaps because of the angle, the room was really dark.

With the help of night vision, Ye Lin saw everything as if it were daytime. The furnishings in the room, the lines drawn on the ground, and the bloodstains on the ground were all clearly visible.

He put on shoe covers, walked along the edge to the cabinet containing gold, smeared white powder on the shoe covers, and then began to simulate the scene that night.

He first stood at the place where Niu Jianmin fell and simulated the action of stabbing with three knives.

Then he took a step forward and stabbed Shi Fuzhen twice where she fell.

Then he retreated to the door of the room, stood behind the door and attacked Niu Xiaowei, then went back to the cabinet, knocked on the lock, took the gold, closed the door and left.

After everything was done, Ye Lin turned on the light, and the white shoe cover prints were clearly left on the floor.

The footprints were very messy. Even with his night vision, he couldn't completely avoid the blood in the previous action, especially when killing Shi Fuzhen, many white footprints had stepped on Niu Jianmin's blood.

If it were someone else, it would be impossible to kill two people and injure one person in such a dark environment without leaving any footprints. So there can only be one answer.

What he needed now was evidence to support him. He stood at the door and slowly looked around the room.

The utility table originally had a metal ornament on it, which was taken away as evidence. There were also a few small items piled up on it.

Over there is a dining table with some pickles on it, which should be what the old couple usually eat.

On the left hand side is a large fish tank with water plants and rockery inside. Ye Lin had seen it before. There is a cabinet under the fish tank. This design can provide more storage space for the family.

Ye Lin walked over and opened the cabinet, which contained some ordinary household napkins and some large packages of food with fish drawings on them.

Ye Lin picked it up and took a look. It was fish food.

He opened a bag of fish food. Half of the food had been used, and the rest was neither spoiled nor damp.

Ye Lin slowly closed the cabinet door and stared at the fish tank. It was a large fish tank, one meter long and half a meter high. It was filled with water plants and rockery, and underneath was a thick layer of pebbles, making it look more like a natural ecology.

There is an air pump installed on the edge of the fish tank. Although Ye Lin does not raise fish, he knows that it is used to increase oxygen for the fish in the water.

On the other side of the frame is a long pipe leading into the water, with some remaining fish food in it.

Ye Lin stood up without hesitation and reached his hand down.

After a while, Ye Lin came out of the room and asked the two policemen at the door: "Are you familiar with this community?"

"It's okay, we will be here in a few days. We know the general situation. Captain Ye, what do you want to ask?" One of the policemen replied.

“How often is the garbage in this community usually cleared?”

"Well, these are fixed points, from 6:8 to : every morning, and in the evening as well." The police officer answered casually.

"What if it's past the time? For example, what if you want to throw away the garbage in the middle of the night?" Ye Lin continued to ask.

"That won't work. The inspection is strict now. The trash cans are locked at night. We can't throw them away."

"If you had to throw something away, where would you say it would be? In the community."

"Hmm..." The policeman lowered his head and thought for a while, "There's a recycling station for clothes, you can throw them in there."

Ye Lin was overjoyed when he heard this, "Come on, take me there."

"Brother, you guard this place well. Anyone who wants to go in must call me for permission. Remember, it doesn't matter who you are, including your Li Police Station." Before leaving, Ye Lin turned around and gave serious instructions to another policeman.

"Understood, Captain Ye." The buddy agreed quite readily.

Under the guidance of the police, Ye Lin came to the clothes recycling bin, a square iron cabinet with an opening for putting things in, but a key was required to take things out.

"Does the property have the key?" Ye Lin asked.

"Probably not. This was commissioned to a third party, and the keys are in the hands of the third-party recycling company." The policeman shook his head.

Ye Lin looked around, picked up a stone, and smashed it at the padlock.

This is originally a simple lock. To put it bluntly, these recycled clothes are unwanted by others, so no one comes to steal them. The lock is installed just for show, and it is not strong at all.

With just three pushes, Ye Lin broke the lock and opened the metal door. Inside were piles of clothes, piled together in a mess. These clothes were collected about once every half a month, so it was probably not time to collect this batch yet.

He pulled out all the clothes, most of which were packed in bags.

He took a quick look and saw that they were all daily clothes, with only a black clinker bag, but he couldn't see clearly what was inside.

Ye Lin pulled it over, opened it, and inside was a pair of dirty leather shoes.

"This looks like a branded product, Captain Ye. Why are you throwing away such good shoes?" The policeman standing by was a connoisseur of the goods.

Ye Lin didn't say anything. He carefully picked up the leather shoes and looked at the soles with a flashlight.

The eye-catching red color and a special smell of blood.

"It's blood, Captain Ye." The police officer exclaimed.

"Yes, this should be human blood." Ye Lin was also very happy. These leather shoes should belong to the murderer. If he guessed correctly, the blood should belong to the two deceased.

He decisively took out his phone and called Sun Jinghua, "Xiao Sun, contact colleagues in the technical department immediately and have them work overtime tonight to conduct the appraisal."

After that, he picked up the clinker bag and carefully wrapped the shoes, and said to the policeman earnestly: "Be sure to keep an eye on the door of the crime scene, and wait for me to come tomorrow."

"Don't worry, Captain Ye." The policeman was also very excited. He had a feeling that the case would have a result tomorrow and they wouldn't have to work overtime or stand guard late at night.

Tonight is destined to be a sleepless night, and the lights in the police station remain on until dawn.
