Things that solve crimes

Captain Chen's mouth went dry after talking for a long time, and he couldn't help but pick up the paper cup at hand and take a sip of water.

"What about Yang Lan?" Seeing that he stopped talking, a young detective asked anxiously.

After drinking a glass of water, Captain Chen continued, "The neighbor of the deceased was a romantic man. The red flag did not fall down at home, but the colorful flags were flying outside."

"Three months before the incident, he met Yang Lan in a bar."

"The man was affectionate and the concubine was interested, so the two hooked up. After that, Yang Lan was raised by him in the villa next door to the deceased's family. She would go there from time to time."

"On the day of the incident, he also went to see Yang Lan. The strange thing was that Yang Lan was not at home, but came back in the middle of the night."

"Yang Lan told him that she was playing outside with the little sisters she knew, and she came back late."

"I also showed him a photo of the little sister. After his description and identification, I was sure that the little sister was Feng Yu."

After Team Chen finished speaking, a young criminal policeman couldn't wait to say, "Feng Yu and Yang Lan were found in the Yangdan case, which means these people are really exchanging murders."

"Evidence, we need to find evidence. Even if these people are really exchanging murders, we can't arrest them without evidence."

An old detective rolled his eyes and said, "The murder evidence hasn't been found yet. Why are you so excited?"

The young detective who spoke was feeling weak. To be honest, it was a bit difficult to find evidence that the two men committed murder.

First of all, the case occurred at night, which meant that it was difficult to find witnesses.

Secondly, there was no surveillance around the deceased's family, and it was impossible to prove that the two people had been to the deceased's house.

"Are there any traces of other suspects in Yang Lan's case?" Qin Henian asked.

Captain Chen smiled bitterly, "No."

Qin Henian lowered his head and thought for a moment before looking up and saying, "Is it possible that the deceased in the Yang Lan case has been brought into the park, but we have no doubt about it."

In Yang Lan's case, the park had two entrances and exits, and there were businesses near these two entrances and exits.

Almost all businesses have installed surveillance cameras, which means that the murderer taking Yang Lan into the park must have been filmed.

"There is another problem. No one entered the park before the death of the deceased, so the deceased should have been brought into the park in advance."

"What can stay in the park for a long time without attracting people's attention?" Qin Henian asked again.

"I remember we were pruning branches in the park during those days." A middle-aged detective suddenly said.

"Garbage truck" Qin Henian blurted out.

He clarified his thoughts and said, "The park is pruning branches. The pruned branches need to be used by garbage trucks. They will not attract attention when they come in and out or stay for a long time."

"And the back of a garbage truck is big enough to hide a person."

After Qin Henian finished speaking, everyone's eyes lit up, and Team Chen quickly brought in all the surveillance videos from the day of the incident.

Everyone watched the video in the conference room...

In the darkness, only the screens glowed with light. Qin Henian blinked his sour eyes, raised his head, closed his eyes and pinched the bridge of his nose with his hand.

Opening his eyes, he put down his hands and sighed. The video wasn't that good to watch. He watched it from afternoon to night and felt like he was going blind.

Looking at Captain Chen next to him, he looked exhausted but still persevering, Qin Henian couldn't help but admire him.

Feeling that his eyes were still uncomfortable, he silently stretched out his hand to press on the top of his eyes, performed eye exercises, and started walking~

After doing a complete set of eye exercises, he felt more comfortable, went to make another cup of coffee, and then sat in front of the screen to continue watching.
