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

Then he drove to the outskirts of the south of the city and found the location where Ma Chaoran and the two got off the car.

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

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

Springer spaniels are small in size, but they are quite athletic and enduring, and after some training, they are generally used for search work.

Han Bin took out Zhang Zihan's clothes and handed them to the dog trainer on the side, who was responsible for letting the police dog sniff the source.

Although the police dog does not bite, it sometimes loses its temper like a child, so in order not to affect its search work, Han Bin still keeps a certain distance from the Springer Spaniel.

After the Springer dog smelled the source of the smell, the dog trainer gave an order: "Search!"

Springer Spaniel ran out with small steps, the dog trainer followed closely behind, and Han Bin and the others were separated by a few meters.

It's mostly a hillside, with bare trees growing and yellow leaves piling up underneath, clattering on the ground.

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

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

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

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

Springer Spaniel smelled the smell, walked to the right front with a small step, walked more than ten meters, turned right again, walked more than 20 meters, continued to turn right, and walked more than 20 meters.

The dog handler made the Springer Spaniel stop, soothed it, and let it revisit the source of the sniff.

"Search!"

Springer sniffed the ground and walked forward again.

However, following the previous example, after walking for more than ten or twenty meters, he began to turn to the right, and it seemed that he had lost the trace of the smell.

"Zeng, the police dog seems to be spinning in place. Han Bin frowned.

Zeng Ping nodded and walked next to the dog trainer: "Is the scent of tracking 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 some pacification, another attempt was made, but the Springer Spaniel still circled around.

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

"You can see the situation, the police dog can't be counted on, and we have to come by ourselves. Zeng Ping said.

"I suggest that you just search around the police dog and 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 overgrown with trees, the trunks were straight and smooth, and the height was more than ten meters, coupled with the heart-shaped palm-shaped fallen leaves, Han Bin judged that it should be a plane tree.

Han Bin circled around the four and didn't find anything unusual.

At this moment, a shout came from not far away: "Team Zeng, Han Group, I have found something here." ”

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

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

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

"Could it be that the suspect left it. Sun Xiaopeng guessed.

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

"Look around, search carefully, maybe you will find something. Zeng Ping said.

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

"Han Group, let's do it with me. Sun Xiaopeng still had the strength to see, took the stick in Han Bin's hand, and continued to do it.

Han Bin was also happy and relaxed, standing aside and observing.

Sun Xiaopeng scraped the fallen leaves, revealing the land below.

After a while, Sun Xiaopeng cleared out a large piece of vacant land.

"Stop. Han Bin suddenly stopped Sun Xiaopeng and said, "There are footprints in front of you on the right, don't destroy them." ”

Zeng Ping also came over, the footprints were very miscellaneous, and several footprints overlapped together.

"These footprints are very strange, there are no footprints anywhere else, just half a meter square, there are several footprints. Sun Xiaopeng was puzzled.

Zeng Ping squatted down to check it out, and said with a smile: "This piece should have been dug in the pit, the soil layer is relatively soft, and the people who dug the pit stepped the footprints left on it in order to ram the earth." ”

After Zeng Ping finished speaking, he took out his mobile phone and made a call and called the people from the technical team.

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

Han Bin wrinkled his nose: "It's so fragrant." ”

"The perfume bottle has an open lid, and it's only because of the black plastic bag and leather bag that the scent is locked, which may not smell it to us, but the police dog definitely smells it. Zeng Ping explained.

"Since the police dog smelled it, why didn't you dig it up?" Sun Xiaopeng was puzzled.

"Police dogs have a sense of smell that is millions of times that of humans, and we smell the pungent smell of perfume, which is very stimulating to police dogs, but it will affect the search of police dogs. Zeng Ping said.

"No wonder the police dogs searched around, but they didn't dare to approach. Sun Xiaopeng showed a sudden look.

Han Bin put the phone in a plastic bag, and then opened the phone, and the screensaver showed a photo of a young and beautiful woman, who was the victim of the case, Zhang Zihan.

"The mobile phone belongs to Zhang Zihan, so this scarf is likely to be the murder weapon that killed her. ”

Zeng Ping handed over the physical evidence to the technical team and told them to identify it as soon as possible after returning to the sub-bureau.

The group searched again, found no more clues, and left the scene.

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 have had a greater difficulty searching.

On the way back to the substation, Han Bin's mobile phone rang: "Jingle bell......"

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

"Hey. ”

"Binzi, where are you?"

"On the way back to the substation, did you catch Ma Chaoran and Fang Ping?" asked Han Bin.

"Yes, you don't look at who leads the team. ”

"Efficiency is okay. Han Bin said with a smile.

"What about you, have you found the murder weapon and mobile phone?"

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

"Binzi, there is one more thing I want to report to you. ”

"What's the matter?"

"Let's let Tian Li tell you. After Li Hui finished speaking, he handed the phone to Tian Li on the side.

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

"What did she say?"

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

"Did she say what she had done?"

"This one doesn't. ”

"Where is she now?" asked Han Bin.

"She refused to say anything, so I persuaded her to go to the substation and turn herself in, telling her that if she confessed, she would be given leniency. Tian Li said.

"Well done. Han Bin replied and asked, "Where are you now?"

"I'll be at the precinct soon. ”

"When you call Tian Reni, you must stabilize her. Han Bin admonished.

"Yes. ”

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

"I speculated before that the other party was likely to be an eyewitness, but then I thought about it carefully, if it was just an eyewitness, she didn't have to run, so she should have something to do with the case, however, I think she shouldn't have much to do with it, and the main culprits should be Ma Chaoran and Fang Ping. Han Bin analyzed.

"What about the motive for the killing?" Zeng Ping asked.

"It's hard to say, Ma Chaoran is the anchor of the shouting wheat area, Zhang Zihan is the anchor of the dance area, and the styles of the two are also different, so 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 *** homicide, which also fits the characteristics of this case. Zeng Ping said.

"The key now is the identification of the technical team, since Ma Chaoran and Fang Ping have made so much effort to go so far away to discard mobile phones and scarves, these two items must have a lot to do with Zhang Zihan's death. Han Bin took out a box of cigarettes and handed one to Zeng Ping.

Zeng Ping took the cigarette and changed his words: "By the way, what do you think of Duqi?"

Han Bin lit a cigarette and took a puff: "It's good, I have experience and work diligently." ”

Zeng Ping took a few puffs of cigarettes, opened the car window, and flicked the cigarette ash: "There are few people in the second group, and I have left the group now, and I am ready to transfer Du Qi to the second group, what do you think?"

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

Zeng Ping didn't speak, looking thoughtfully ahead.
