Han Bin contacted the Municipal Bureau and Ding Xifeng agreed to stay at the scene of the crime to assist in the investigation.

As for whether the Municipal Bureau will formally intervene in the case, it is not yet known. It depends on the subsequent development of the case.

Han Bin can also be regarded as a front stand. If the impact of the case expands, the city bureau decides to intervene in the investigation and can directly let Han Bin take over the case.

Han Bin still transferred the scene to Zeng Ping. The Municipal Bureau has not yet decided to intervene in the case. He is only assisting in the investigation.

Led by Wang Chang, Han Bin and his party rushed to the spot where the hot air balloon was parked.

The parking place was empty, with a cordon around, leaving a fixed iron pillar. A guardrail in front was a fixed track, at least tens of meters long, and a big hammer was placed beside the track. .

Han Bin, Zeng Ping, and Li Hui looked through the guardrail.

This track is somewhat similar to that of a train, except that this track is a single track, a moving iron gate was knocked off, and the sledge hammer was placed next to it, consistent with the description of the three witnesses.

Han Bin looked around and found no camera.

Han Bin inspected the scene carefully and found a piece of cloth on the steel nails that fixed the track, as if clothes were hung with a hole.

The rag is yellow with some red stars on it. The color and shape look like a clown's clothes.

The distance between the rag and the rail gate was not far, and Han Bin simulated the scene, pretending that he was smashing the iron rope with a hammer, and found that this action might indeed cause clothes to hang if he was not careful.

In other words, this rag is probably on the clown's clothes.

Han Bin just stood on the side to check the rags, but did not pick up the rags. In this regard, the technical department must be more professional.

After checking the scene, Zeng Ping said, “It now appears that the situation on the scene is basically the same as the description of the three witnesses.”

Han Bin stood up and agreed, "This rag is probably hung on the clown's clothes."

Zeng Ping pointed to Li Hui on the side, "You can contact Director Zheng to see if the police at the police station have found the whereabouts of the clown."

Then, Han Bin and Zeng Ping also left the track.

Zeng Ping continued to arrange the task, "Wei Zimo, take someone to check the surveillance and see if you can find the whereabouts of the clown."

"Yes."

After Zeng Ping arranged the task, Han Bin asked, “Team Zeng, from the current situation, Song Bohui is very suspicious, whether he summoned him to make a transcript or directly locate it with his mobile phone.”

Zeng Ping naturally did not forget Song Bohui's clue, and he was also thinking about how to investigate Song Bohui's suspicion.

There is no direct evidence to prove that Song Bohui is related to this case, but according to Zhang Li's transcript, Song Bohui did have a certain motive for committing the crime.

"Isn't there his phone number? Let's call it normally."

Han Bin took out his cell phone and dialed Song Bohui's number. The cell phone kept ringing, but Song Bohui did not answer.

Han Bin called Song Bohui three times without answering the phone.

He spread his hands flat against Zeng.

Zeng Ping frowned and said to Tian Li on the side, "The people who contacted the technical team, ask them to help locate Song Bohui's mobile phone number. Also inform Song Bochen's parents to identify the body."

"Yes."

After Tian Li left, Han Bin walked to Wang Chang, "Manager Wang, I would like to ask you for help."

"You say."

"How many clown costumes are there in your playground?"

"Two sets."

"How many people have played the clown?"

"Also two."

"Then please call the two employees who have played the clowns. I have questions and want to ask them. Besides, I will take two more clown costumes."

Wang Chang wiped the sweat from his forehead, "Then you wait a moment, I have to check."

After Wang Chang left, Han Bin and Zeng Ping exchanged a few words.

Li Hui came over and said, "Team Zeng, Team Korea, I contacted Director Zheng, his people did not find the whereabouts of the clown."

Han Bin didn't report much hope, and handed Li Hui a cigarette, "This clown dares to make trouble and kill people, but he has prepared in advance. It is indeed not that easy to be spotted."

Li Hui took the cigarette but didn't set it on fire. He thought thoughtfully, "You said it is possible for the clown to premeditate murder, but how can he be sure that the dead will ride in a hot air balloon?"

Han Bin replied, "According to the staff in charge of the hot air balloon, the clown was carrying a knife. He might have planned to kill with a knife, but when he saw the deceased sitting in the hot air balloon, he changed to a more subtle way of killing. ."

"Your guess is possible." Li Hui replied, and the conversation turned, "However, the clown's knife is not necessarily used to kill the person, but it may also be used to scare off the person who wants to catch him. Is it possible that the clown I knew in advance that the suspect would get on the hot air balloon, so I prepared a hammer in advance to let the victim die on the hot air balloon."

Zeng Ping said, "According to what you said, the most suspicious person is Zhang Li, and only she can ensure that Song Bochen will ride in a hot air balloon."

Han Bin thought of other clues and pondered for a moment, "One will ask the staff of the playground to identify whether the hammer is from the playground. If it is from the playground, who keeps it there? Maybe some clues can be found."

Li Hui lit his cigarette and took a sip, "That's right, people were killed in the playground and died in the playground project. Anyway, the playground is responsible."

At this moment, Wei Zimo sent a video, "Team Zeng, we found a clown figure in the surveillance. As Captain Han said, the clown was wearing a pointed cap and holding an animal balloon in his hand."

Zeng Ping asked, "Have you found the whereabouts of the clown?"

"It's still investigating and monitoring, it will take some time."

"Then send a screenshot of the clown, and I will let the witnesses recognize it."

"Yes." Wei Zimo responded, and then sent a screenshot of the clown's video to the work group.

Zeng Ping, Han Bin, Li Hui and others all saw the appearance of a clown.

Then three witnesses, Zhang Li, Wang Xiaoyi, and Zeng Shaowei, were found to identify them. All three of them identified the clown who broke the steel cable gate.

Han Bin checked the photos carefully and found that the clown’s pants were the same color and shape as the rags found at the scene. Then, he asked Wei Zimo to send a video. After some comparisons, he found that the clown’s pants had a The hole matches the shape of the rag found at the scene.

It is basically certain that the clown in the video is the suspect.

After identifying the suspect, Han Bin called the employee Wang Xiaoyi who was in charge of the hot air balloon again, "Miss Wang, I heard that there are clowns in your playground?"

Wang Xiaoyi pursed his lips and replied in a low voice, "Yes, but not every day."

"Is this clown an employee of your playground."

"He is wearing a mask, I can't recognize him."

Han Bin pointed to the video, "What about his costume, is it the same as the clown costume in your playground?"

Wang Xiaoyi showed hesitation...
