At three o'clock in the afternoon, three police cars slowly drove to the Jiangfengcun section of the North Branch of the Yangtze River.

A suspect in his thirties who was wearing handcuffs and shackles, and the handcuffs and shackles were connected with an iron chain, was escorted out of the police car by three criminal police officers.

Han Yu and Xiaoyu saw the suspect for the first time today, but they had heard about it more than once.

The guy who was brought to identify the scene where the murder weapon was abandoned was named Chen, and his name was Chen Xiaodong. He lived in Group 6, Jiangfeng Village, under the river embankment.

He was a frequent visitor to the No. 4 Police Station. He was sent to a labor camp for two years for theft when he was in junior high school.

After returning from the labor camp, he had nothing to do and started stealing again. Less than three months after returning home, he was sentenced to three years for being suspected of theft.

A few days after he was released from prison, he actually raped a woman in the village who had some mental problems. Her husband sued her and she was sentenced to a few more years.

A month and a half ago, he targeted an old man who was watching the blockade nearby.

Late at night, he went into the shed built inside the water conservancy gate and committed theft. He was discovered by the old man who woke up, so the theft turned into robbery and murder!

After the murder was discovered, he was the first person that the Criminal Police Brigade and No. 4 Police Station thought of. It is said that he confessed to the murder, but they did not expect that the key evidence of the murder weapon was missing.

Han Yu glanced at the suspect curiously and signaled to Wang Yan, who personally led the team to escort the suspect, to quickly ask the suspect to identify the location where the murder weapon was abandoned.

Xiaoyu walked up to him and observed calmly, wanting to see if there were any injuries on the suspect's body, so as to determine whether Wang Yan and other criminal police officers had used torture to extract a confession, and whether the suspect had been beaten into submission.

Wang Yan didn't know what Xiaoyu was looking at. He simply thought that Xiaoyu wanted to take a closer look at the murderer. After all, murderers were rare in Linghai.

"Stop dawdling, think carefully about where you threw the dagger!" Wang Yan grabbed the suspect's arm and pulled the suspect forward.

"It seems to be there."

"where?"

"Over there, over there with the plastic bags."

Fang Zhiqiang followed behind, heard clearly, and looked at Han Yu subconsciously.

Han Yu pondered for a moment and asked:

"What time of night was it when the dagger was thrown?"

Fang Zhiqiang studied the dossier repeatedly and said without hesitation:

"He said it was around three o'clock in the morning."

"Around three o'clock in the morning..." Han Yu thought about it and asked again:

"He stabbed someone to death with a dagger. Is there any blood on him?"

"No." Fang Zhiqiang stopped, looked at the suspect in front of him and said:

"It was during the Chinese New Year when I got my hair. The weather was still very cold, so I wore thicker clothes."

Xiaoyu ran back and asked puzzledly:

"Then how did you determine that he was a murderer?"

"He himself admitted that he did come to the river on the night of the incident. The technical police extracted his footprints near the incident site, and the shoe prints matched his shoes." Fang Zhiqiang paused and added:

"Furthermore, we haven't identified him as the murderer yet, otherwise we wouldn't have brought him to identify the scene, let alone ask for your help."

"He admitted it?"

“The attitude is very cooperative.”

Just as he was talking, Wang Yan also ran back and took out the flue:

"Salted fish, he said he would just throw it here. He also said he heard the sound of a dagger falling into the water when he threw it."

Before Han Yu could speak, Xiaoyu looked at the location identified by the suspect and said:

"impossible."

"impossible?"

"A month and a half ago, around three o'clock in the morning, the tide did not start to rise in this area. There was no water in the location he pointed out just now. How could he hear the sound of a dagger falling into the water!"

Seeing Fang Zhiqiang and Wang Yan looking at him at the same time, Han Yu confirmed:

"Discarding the murder weapon does not mean throwing a grenade. Even if a grenade was thrown, based on the tide level at that time, this area would be a beach full of water. He could not have thrown it that far, and it was impossible to hear the sound of the dagger falling into the water."

"Did you hear that? You don't believe me!" Xiao Yudi said.

"It's not that we don't believe you, but...but this situation is of great importance."

"Then do we want to salvage it?"

"Wait a minute, I'll go and ask him properly."

"Hurry up."

Xiaoyu was still thinking about playing games and was a little impatient.

Han Yu put on his rain boots and carefully followed the gentle slope of the river embankment to the muddy river beach, where he frightened away a few small crabs.

Xiaoyu hesitated for a moment, then returned to the car and slowly put on the old money that he hadn't worn for several years.

"Shuiguai" also followed Han Yu downhill and onto the river beach.

"Little fish, when the tide goes out, it doesn't mean there is no water on the beach. Move the reeds and see if there are any ponds or puddles."

"OK."

A criminal policeman stood on the shore and couldn't help shouting:

"President, we searched this area but couldn't find it."

"I know, let's take a look." Han Yu didn't like it from the bottom of his heart.

The title "President" is what old friends call me, so I can only accept it.

The little fish suppressed a smile and asked curiously while pushing aside the reeds to search carefully:

"Dried salted fish, Political Commissar Jiang said that you want to be transferred back to our branch. Is this the case?"

"Not even a single stroke of the eight characters."

"How come you don't even have a single character?"

"Zeng Guan, Ma Guan and Political Commissar Zhou said that if people go to higher places, water will flow to lower places. It is okay to transfer them back, but only if the Changhang Public Security Bureau becomes an administrative unit."

"Bureau Qi and Political Commissar Jiang said that the Public Security Bureau of the Ministry of Transport has reported to the superiors. Once approved, we can all be transferred to civil servants. From now on, we will be administrative police just like the local police!"

"I hope so too, but can the superiors approve or retaliate?"

…

The two of them walked and chatted, and searched for more than an hour on the reed-covered and extremely muddy river beach. Except for a pile of white garbage collected by the way, a few ground traps and two small crabs caught by small fish, they found nothing.

Back on the shore, Han Yu said in a positive tone while changing his shoes:

"If the suspect remembers correctly that the murder weapon was thrown in this area, then the murder weapon will definitely not be washed away by the river."

"There are many reeds, are they blocked by the reeds?" Fang Zhiqiang asked in a low voice.

"Well, the reeds below are denser than those on the shore. We can't even move our legs below."

Han Yu looked back at the river beach, thought about it and added:

"Furthermore, when the tide rises, a piece of sand will be taken away, and when the tide falls, a piece of sand will be taken away. Two tides a day, and so on, so the bottom is flatter than we thought. At least the area that Xiaoyu and I just walked through is not there.

Found puddles and ponds.”

Xiaoyu was afraid that the second senior brother would not understand, so he emphasized:

"Again, if the suspect really threw the dagger around three in the morning, he would definitely not have heard the sound of the dagger falling into the water."

"I understand, let's go back and review it again."

Fang Zhiqiang walked aside and called the bureau leader to report.

Wang Yan looked at Han Yu and Xiaoyu but hesitated to speak.

Han Yu could understand his mood at this moment. He thought that the case that was certain was actually suspicious, which meant to the police that the previous investigation was not meticulous, and that the previous work might be in vain.

But this is fate, and the evidence must be conclusive.

Han Yu was helpless and stuffed his dirty rain boots into the bag.

He opened the suitcase of the Changhang Branch police car, stuffed the woven bag in, and headed back home with Xiaoyu.

Xiaoyu glanced at the rearview mirror, held the steering wheel and asked:

"Dried salted fish, if you can't find the dagger, is Wang Yan going to let that bastard go?"

"That bastard has admitted it, so it's probably impossible to let him go."

"You can't let him go, and you can't complain, so why should he be locked up like this?"

"There are many people who have been detained for extended periods of time. It is said that some of them can be detained for as long as two or three years."

"That's not what was said in the training, and that's not what is written in the Criminal Procedure Law!"

"It is easier said than done to suspect a crime."

Han Yu looked back at the Linghai Public Security Bureau police car that had just followed him, and said helplessly:
