National Forensic Doctor

"Go and ask if there are any cameras."

Jiang Yuan saw that there were several small shops opposite the park. If he was lucky, there might be cameras that could capture people entering and leaving the park.

Mu Zhiyang immediately arranged for two pairs of people to inquire separately, and whispered: "If we reveal our identities and check the cameras, the kidnappers may receive the news."

"Just record the shop owner's mobile phone number and WeChat ID, and warn him not to send random messages in groups and Moments." Jiang Yuan has experienced so many cases, and he doesn't think anyone would dare to tip off the three kidnappers now. .

The relatives and friends of the three people have been investigated, and those who need to be investigated have also been investigated. If anyone dares to tip off the information, they are making themselves uncomfortable. The Internet Security Brigade probably won't mind taking some credit.

As far as the current environment is concerned, the channels through which the three kidnappers can obtain information are either through their own investigation, or through public channels such as mobile phone groups or circles of friends.

Even investigating by himself, Jiang Yuan found it not easy. Assuming that they can arrange shifts and only monitor places other than their hiding spots, it is almost the same as standing guard. Without any military quality, they will not be able to persist.

This is also the basis for hunting them down. If the kidnappers had some way of being able to see and listen in all directions, they would have run away the moment the hostages were discovered.

The two pairs visited each home, and soon the news came back, but there was no camera that could capture the entrance and exit of the park.

There are all small shops here, and only three of them have cameras installed. None of them have cameras directed at the entrance and exit of the park.

Jiang Yuan nodded when he heard it.

Mu Zhiyang was even more worried than Jiang Yuan, and said: "There are public toilets where people come and go. Even if Da Zhuang comes, he will have to numb his claws."

The success rate of police dogs tracking in cities is not high, and the abilities of different police dogs vary.

By analogy with hunters hunting in the mountains, the success rate of dogs tracking prey is also limited, which is more or less a matter of luck.

The clues of the footprints were also broken. As Jiang Yuan thought about it, he couldn't help but think of the pollen picked up from the pickup truck.

The pollen obtained through forensic botany is the most important evidence he has obtained recently. The search for the hostages relies on the pollen obtained from the foot pads and footrests, which is equivalent to indirectly providing a place for the passengers to stay.

In addition to the pollen in these two places, pollen and sporopollen were also found in other locations on the pickup truck, with varying degrees of difference.

Jiang Yuan asked for the pad again, opened the local satellite image, and studied it carefully.

"Morning glories, hydrangeas, violets..."

These are pollen found in other parts of the pickup truck. The quantity is not large and the proof is not strong, but it seems feasible to try to use it to guide the way.

However, looking at the residential areas scattered around, Jiang Yuan could not tell where these flowers were and where they were not.

After searching again and again, Jiang Yuan saw a field of poppies in the green space on the roadside a little to the south.

To the criminal police, this flower, which is very similar to the poppy, is still a bit eye-catching. If you identify it carefully, you will see that the plant on the roadside has rough hair all over. It is definitely a poppy.

When searching for pollen on the pickup truck, poppy pollen was also found.

"Go to the south and have a look." Jiang Yuan estimated that the pickup truck had picked up pollen when it passed through the green belt in the south, so he took the opportunity to take a look.

A few people were walking and watching as they walked.

When walking through the field of poppies, Jiang Yuan paid close attention and saw that there were no poppies in the plants, so he continued walking.

Some idiots grow poppies and the like in their own yards, and they like to mix poppies with them. In fact, ordinary people don’t know poppies anymore, and how can professional anti-narcotics personnel not tell the difference between poppies and opium poppies.

After passing the green belt planted with poppies, continue forward for a while, and you will reach a fork in the road. On the right side is a brand new community with 20 or 30 high-rise buildings. On the left is an urban village near the river, a cluster of self-built houses.

Needless to say, he must have gone to the village in the city.

The new community in Luojin City has access control, security and cameras, which is obviously not suitable for the life of the three kidnappers.

As for the village in the city, Jiang Yuan is too familiar...

"Let's go and have a look." Jiang Yuan whispered, and Mu Zhiyang understood.

Walking through the entrance of the urban village, although there were a few old men chatting in front of them, no one paid attention to the people going in and out. If you were driving, it would be smooth.

In the village in the city, the roads were narrow and the parking spaces were in a certain order. Jiang Yuan and others walked all the way in and soon reached the river.

The river is unknown, but it is more than ten meters wide, and the green water is unknown how deep it is.

There were two or three food stalls or teahouses by the river, and there were several speedboats and fishing boats parked by the water. Jiang Yuan saw this and without hesitation, he took out his mobile phone and called Huang Qiangmin.

When the reinforcements arrived, Jiang Yuan led Mu Zhiyang and others forward and took control of the ships, especially the speedboats.

Someone from the river came over shirtless and asked in a bad tone: "Who are you?"

"Police." Maki showed his work ID and asked, "Whose boats belong to them?"

"Those are all village boats." The shirtless man's tone became much gentler when he saw the police badge.

"Are they all from your own village? Are any of them rented out or bought by outsiders?" Mu Zhiyang asked.

"Yes. Today's boats are not for work, they are just for fun. If you want to rent them, we will rent them." The shirtless man replied.

Jiang Yuandao: "Show him the photo."

Mu Zhiyang then showed the photo of the three kidnappers to the other party and asked, "Is there a boat they rented?"

The shirtless man frowned and looked at it for a while, then said uncertainly: "I can't quite tell... There are two people who look a bit alike... Both of them wear masks and occasionally sail boats. Go out, say it's fishing or something..."

"Don't you even read the news?" Mu Zhiyang asked as he put away the photos.

"No serious person would look at that." The shirtless man laughed.

"Both of you, do you have any records of renting a boat? Do you have any records of stopping a boat? Do you usually write anything?" Mu Zhiyang asked.

The shirtless man nodded: "You have to pay the berth fee, and you have to pay for boat cleaning and other things."

"Show us your record book." Jiang Yuan and Mu Zhiyang followed and saw the other party taking out a registration book.

The register records are very simple, only the ship number, time and money, but at the end, a series of numbers are recorded.

Jiang Yuan looked familiar and asked, "Is this the room number?"

"right."

"1307030, what does it mean?"

"Building 13, 7th floor, No. 3, 0 means the house is rented as a whole. If it is rented separately, write the number later."

Jiang Yuan nodded, Luo Jin City's habits were similar to Ningtai's.

Jiang Yuan called Huang Qiangmin again and told Mu Zhiyang: "Keep your guard, beware of dogs jumping over the wall."

"Don't worry." Mu Zhiyang looked serious.

Several people on the shore were also left behind, waiting stupidly beside them.

In about 10 minutes, Huang Qiangmin sent a WeChat message to Jiang Yuan: "It's started."

I saw a thud in the village, but I couldn't hear the specific sound, and I heard all kinds of chaotic sounds in the village.

Then, Huang Qiangmin called: "Caught him, all three of them are here, cooking noodles."
