Han Bin and Sun Xiaopeng went to the taxi company first and found the driving records of Ma Chaoran and Fang Ping taking a taxi.

Then drove to the southern suburbs of the city and found the place where Ma Chaoran got off.

Not long after, Zeng Ping also led the police dog brigade and technical team.

This time it was not a Labrador retriever, but a brown and white Springer Spaniel.

The Springer Spaniel is not big, but its athletic ability and endurance are quite outstanding. After some training, it is generally used as a search job.

Han Bin took out Zhang Zihan's clothes and handed them to the dog handlers who were in charge of letting the police dogs sniff the source.

Although police dogs don't bite people, they sometimes get angry like children. In order not to affect its search work, Han Bin still keeps a certain distance from the Springer Spaniel.

After the Springer Spaniel smelled the source, the dog handler gave an order: "Search!"

The Springer Spaniel ran out with a small bump, the dog handler followed closely, and Han Bin and others were separated by a few meters.

Here are basically hillsides, with strips of bare trees growing, yellow fallen leaves piled up below, and "chattering" on the ground.

After walking for about a hundred meters, the Springer Spaniel stopped, sniffed the ground with his nose, and then looked at the dog handler with a pair of innocent eyes.

The dog handler took out Zhang Zihan's clothes again, let the Springer Spaniel smell it, and then let it continue searching.

The Springer Spaniel smelled the scent trail on the ground, walked more than a hundred meters forward, and stopped again.

The dog handler let it sniff the source again and ordered: "Pengpeng, search!"

The Springer Spaniel sniffed the smell, took a small bump and walked forward to the right. After walking more than ten meters, he turned right again, walked more than 20 meters, and continued to turn right, and walked more than 20 meters. .

The dog handler stopped the Springer Spaniel, soothed it, and let it listen to the news.

"Search!"

The Springer Spaniel sniffed the ground and moved forward again.

However, just like the last time, after walking more than ten or twenty meters, he began to turn to the right, seeming to have lost the trace of smell.

"Team Zeng, the police dog seems to be spinning around." Han Bin frowned.

Zeng Ping nodded and walked to the dog handler: "Is the traced smell missing?"

"It may be that the smell has disappeared, or it may be that there is a pungent smell nearby, which affects the judgment of the police dog." The dog handler stroked the Springer Spaniel's head.

After calming down, he tried again, but the Springer Spaniel was still spinning around.

Zeng Ping asked the dog handlers to take the Springer Spaniel to rest in the police car. He, Han Bin, and Sun Xiaopeng stayed nearby.

"You have seen the situation. The police dog can't count on it anymore. We have to come by ourselves." Zeng Ping said.

"I suggest that you search around the police dogs to see if you can find any clues." Han Bin said.

"I'm going east." Zeng Ping said.

"I'm going south." Han Bin said.

Sun Xiaopeng went to the north.

Han Bin observed the surrounding terrain. The hillside was covered with trees, the trunks were straight and smooth, and the height was more than ten meters. With the heart-shaped palm-shaped leaves, Han Bin judged that it should be a plane tree.

Han Bin went around and found nothing unusual.

At this moment, there was a shout not far away: "Team Zeng, Team Han, I found out here."

Han Bin walked in the direction of Sun Xiaopeng: "What's the matter?"

"A cigarette **** was found here." Sun Xiaopeng pointed to the ground not far away.

Han Bin put on his gloves and picked up the cigarette butt: "Who would come here to smoke in such a remote place."

"Will it be the suspect left?" Sun Xiaopeng guessed.

"Team Zeng, what do you think?" Han Bin asked back.

"Check around, search carefully, maybe you will find it." Zeng Ping said.

Then, Han Bin took a branch and scraped away all the fallen leaves around. The fallen leaves were thick, and this job was not easy.

"Han Group, let me do it." Sun Xiaopeng still had eyesight, took the stick in Han Bin's hand, and went on.

Han Bin was also happy and relaxed, standing aside to observe.

Sun Xiaopeng scraped away the fallen leaves, revealing the ground below.

After a while, Sun Xiaopeng cleared a large vacant lot.

"Stop." Han Bin stopped Sun Xiaopeng suddenly and said, "You have footprints in front of you, don't destroy it."

Zeng Ping also leaned over, his footprints were mixed, and several of them overlapped.

"These few footprints are very strange. There are no footprints anywhere else. There are several footprints in the half-meter square." Sun Xiaopeng said in confusion.

Zeng Ping squatted down to check, and smiled: "This piece should be a pit that has been dug, the soil is relatively soft, and the digger's footprints left on it to ram the soil."

After Zeng Ping finished speaking, he took out his cell phone and made a call, calling the technical team over.

The technical team collected the shoe prints, dug up the soil under the shoe prints, and found a black plastic bag. The bag contained a scarf and a small purse. The purse contained a mobile phone, perfume, small mirror, and pressed powder.

Han Bin wrinkled his nose: "It smells so good."

"The perfume bottle has the lid open. It is only because of the black plastic bag and leather bag that the scent is locked. It may not be smelled for us, but the police dog must smell it." Zeng Ping explained.

"Since the police dog can smell it, why not dig it up?" Sun Xiaopeng asked in confusion.

"The sense of smell of police dogs is millions of times that of human beings. We smell the pungent perfume, which is very irritating to police dogs, but it will affect the search of police dogs." Zeng Ping said.

"It's no wonder that the police dog only searched around, but didn't dare to approach." Sun Xiaopeng showed a daze.

Han Bin put the phone in a plastic bag, and then opened the phone. The screen saver showed a picture of a young and beautiful woman, Zhang Zihan, the victim of this case.

"The phone belongs to Zhang Zihan, so this scarf is probably the murder weapon to kill her."

Zeng Ping handed over the physical evidence to the technical team and told them to appraise it as soon as possible after returning to the branch.

The crowd searched again, and they left the scene without finding any more clues.

Han Bin took out a pack of ham from the car as a reward for the Springer Spaniel. If it hadn't found the approximate range, the police would find it more difficult to search.

On the way back to the branch, Han Bin's cell phone rang: "Dingling..."

Han Bin took out his mobile phone and looked at Li Hui's number displayed on the screen.

"Hey."

"Binzi, where are you?"

"On the way back to the branch, have you caught Ma Chaoran and Fang Ping?" Han Bin asked.

"It's a must, you don't look at who leads the team."

"Efficiency is fine." Han Bin smiled.

"How about you, have you found the murder weapon and cell phone?"

"I found it, Zhang Zihan's mobile phone and a scarf. As for whether it is a murder weapon, it needs to be tested."

"Binzi, there is something else I want to report to you."

"what's up?"

"Let Tian Li tell you." After Li Hui finished speaking, he handed the phone to Tian Li who was aside.

"Group Han, Tian Ruini called me just now."

"what did she say?"

"She asked me, if I go to the branch now, would it be considered a surrender?" Tian Li asked.

"Did she say what crime she committed?"

"This does not."

"Where is she now?" Han Bin asked.

"She refused to say, I persuaded her to surrender to the sub-bureau and told her that as long as she confessed, she would be treated with leniency." Tian Li said.

"Good job." Han Bin responded and asked, "Where are you now?"

"It will be the branch soon."

"You call Tian Ruini, you must hold her steady." Han Bin warned.

"Yes."

Zeng Ping was next to him. He listened to the conversation on the phone and asked, "You said, what role did Tian Ruini play in this case."

"I previously speculated that the other party was probably an eyewitness. Then I thought about it carefully. If she was just an eyewitness, she didn't have to run. Therefore, she should have a certain relationship with the case. However, I think her relationship should Not big, the main offenders should be Ma Chaoran and Fang Ping." Han Bin analyzed.

"What was the motive for the murder?" Zeng Ping asked.

"It's hard to say, Ma Chaoran is the anchor of the shouting area, and Zhang Zihan is the anchor of the dance area. The two have different styles. It stands to reason that there is no conflict of interest between the two." Han Bin said.

"If there is no conflict, then it is likely to be a gang murder, which is also in line with the characteristics of this case." Zeng Ping said.

"The key now is the appraisal from the technical team. Since Ma Chaoran and Fang Ping had spent so much effort, they went to such a long distance to discard their mobile phones and scarves. These two items must have been related to Zhang Zihan's death. Great relationship." Han Bin took out a pack of cigarettes and handed one to Zeng Ping.

Zeng Ping took the cigarette and changed the conversation: "By the way, what do you think of Ducci?"

Han Bin lit a cigarette and took a sip: "It's good, he has experience and is hardworking."

Zeng Ping smoked a few cigarettes, opened the car window, and flicked the soot: "The second group has fewer people. I am now leaving the group. I am going to transfer Ducci to the second group. What do you think?"

"Naturally I can't ask for it." Han Bin smiled and asked, "Sister Zhao agrees?"

Zeng Ping did not speak, but looked forward thoughtfully.
