Yan Ruyu and Hei Baogong had heard the content of the phone. The two of them quickly returned the things in their hands, checked them, and confirmed that there were no traces of search.

"Lao Yan, what did you mean just now?" Wu Cuo asked after leaving the door.

"It's a long way to speak, just tell the conclusion. The key to solving the case lies in Wang Zilong." Yan Ruyu said.

"Prince Long? Why?"

"Prince Long killed someone passionately when he thought his mother was dead. This can be proved by the fact that Wang Jian had two injuries on his neck.

But now he found that his mother was not dead, can you imagine his mood?"

Wu Cuo said: "There is a saying above that 10,000 heads whistle by. This is probably the feeling. Of course, there will be the joy of losing and regaining it."

Hei Baogong nodded, "He will cherish the time he spends with his mother more and try his best to escape legal sanctions."

"So, if," Yan Ruyu said, "I mean, if, if we found evidence of Prince Long's crime, think about it, what would he do next?"

Without waiting for the two to answer, Yan Ruyu continued: "Let's go second. Since he cannot escape the legal sanctions, he will definitely give up his accomplices in order to reduce his sentence."

"I understand. Let's find evidence of Wang Zilong's crime first, and he will find the dissector." Wu Cuo cheered up and said, "I'll go and investigate the scene of Wang Jian's murder!"

Hei Bao Gong also said: "I will take someone to search Wang Zilong's house and I will confirm his crime."

There were few pedestrians in the alley at the crime scene, but because of the murder, they attracted the attention of the surrounding residents. After dinner, the old men and women gathered at the entrance to discuss. Fortunately, there were auxiliary police on duty and guarding the scene.

At the scene, blood was still there on the ground and the walls, and the splattered blood was shocking. The blood-stained place became a paradise for flies and ants. A group of ants were carrying a small piece of blood scab to advance into the cave.

Brick walls are not conducive to leaving fingerprints. Even if you use a purple light to carefully screen the wall, you still have no gains.

The footprints on the dirt road were complicated and repeated three times. The two bloody footprints attracted the attention of the error.

The first kind of helplessness is very familiar, it is a pair of footprints with shoe covers - similar to the one left by a criminal policeman when he was inspecting the scene with shoe covers.

However, there will be no blood on the footprints of the detective. First, the blood is dry when the scene is surveyed, and second, the detective will be careful to avoid bloody places when walking.

The blood-stained footprints are mixed with the footprints left by the detective and are easily overlooked.

Someone came to the scene with shoe covers!

Is it an anatomist? He is so careful!

Another type of shoe print is very blurry. The reason for the blur is that the pattern on the soles is very shallow, which shows that the shoes are seriously worn, and the shoe print is at the most mottled place on the edge of the wall with the blood stains.

The spots of blood interfere with the sight, making the shoe prints more difficult to identify.

The pattern is like some kind of sneakers, and the shoe size is four-one.

"The day we met Prince Long, he was wearing sneakers, right?" Wumiao asked.

"Um."

"I think the size is similar to this shoe print."

"Um."

Yan Ruyu's answer was absent-minded. He was searching in the trash can where Wang Jian's body was found.

"When I first inspected the scene, I had carefully checked it and there was nothing suspicious." Wu Cuo reminded.

Yan Ruyu did not stop, "The surgical blade is so small, I'm afraid it will miss it."

After being told by Wu Chou, Yan Ruyu turned the trash can upside down, but still found nothing.

He looked at the trash can unwillingly and muttered, "Where will the blade go? Although this thing is small, it is difficult to destroy. It cannot be turned into ashes or tear into pieces. Where will it be thrown? Or hidden at home...

Along the road! By the way, are there any other trash cans along the road?"

Yan Ruyu was talking to herself, and was already running towards the direction of Wang Zilong's family.

Whenever he encounters a trash can on the road, whether it is a public or a bungalow that is placed at the gate, he has to search carefully, and he doesn't care about anything dirty or smelly.

An hour later, Yan Ruyu returned to the scene helplessly.

"Not found?" Wumiao asked,

"Well. It's been three days since the trash cans along the way have been cleaned."

"It seems that I can only rely on shoe printing," Wu Cuo even felt a sense of piety in his heart when taking the shoe printing photos.

The search for Wang Zilong's family made some progress, and Hei Baogong found the wrapping paper of the surgical blade in his trash can.

In addition to Wang Zilong's fingerprint, there is also half of the fingerprint of unknown origin on the wrapping paper.

I didn't find the shoes. Not only did I not have Wang Zilong's shoes at home, but I didn't even have toothbrush towels for daily use.

It's normal, he doesn't always stay at home. This time he comes back, he stays with his mother in the hospital.

Hei Bao Gong said: "I have applied for an arrest warrant and can arrest Wang Zilong and check his shoes."

City Hall, interrogation room.

Prince Long refused everything and brought out the argument that he would rather go to jail for the murderer.

"To be jailed for others? You'd better take care of yourself first."

The comparison results of the sole pattern have come out, which is completely consistent with the footprints on site. Not only the sole pattern, but also the wear level of the sole.

Wu Cuo even extracted blood from the gap in the pattern of his soles.

After comparison, it was the blood of the deceased Wang Jian.

Wang Zilong's lies are self-defeating.

He sighed, his eyes shivered, and he collapsed on the chair in the interrogation room.

The young man who committed the crime for the first time is gradually collapsing his emotions, and his tears and snot are flowing down.

"I don't know... I didn't mean it... I didn't think... I thought my mother was dead, Wang Jian killed me, I just wanted to avenge my mother... I don't know what was thinking at that time... I really made a big mistake this time! What should I do? My mother is still in the hospital, my god...

He could hear his crying in the corridor, and the interrogation could not continue. Wuzhu poured him a cup of hot water and threw a sentence, "Tell me your accomplice, don't miss the opportunity to make meritorious service and reduce sentences." He allowed him to cry and vent his emotions.

Wang Zilong cried for a long time. After crying, he knew that he would have to face it after all.

He gave all the information about the anatomist, but he really didn't know who the anatomist was.

"Mobile phone! Prince Long's mother's cell phone is with the dissectionist! Can we check it from the mobile phone..."

"I used to be with the dissectionist." Yan Ruyu corrected: "He was so careful that he must have dealt with the phone long ago and could not find it."

"Is there no clue at all?" Wu Cuo was very dejected.

Yan Ruyu suddenly changed the topic and said, "I remember you mentioned it before. In order to obtain evidence of pickpocket stealing, the anti-trial team installed hidden cameras in more than a dozen places where theft cases occur frequently in the city."

"That's right."

"Including the night market? It's the most common place with high traffic, right?"

"Why did I forget this?! Let's adjust the surveillance!"

"No, when you first interrogated, Xiao Jinzi had already started to check and monitor."

Jinziduo's efficiency is indeed very high. Soon, a piece of surveillance content was presented to everyone.
Chapter completed!
