This morning's investigation visit should be fruitful: the first scene of the "6,27" headless case should be in the 13th battalion, which is undoubtedly the top priority, and the Ma Po Nunnery and the pickle factory are the top priority; The ship used by the murderer to transport and sink the corpses should be the ship of the pickle factory; The time when the murderer transported and sank the body should be between 11 and 12 o'clock in the evening on April 11; The two city wall bricks used by the murderer to sink the body should have been taken from Ma Po Po Nunnery. Wang Hongbao and his wife were the only ones who had ever spent time in the house of Gao Defeng, and they should have seen the set of keys hanging next to the window.

Of course, there are also people who know that the key is hanging inside the window, as well as people from the pickle factory. Wang Hongbao is definitely not the deceased of the "6.27" headless case, because Wang Hongbao is still alive, so will there be any connection between this Wang Hongbao and the "6.27" headless case?

In short, Zhao Zimeng, Xiao Lao, and Ling Hu Yunfei's thinking is a little confused on the issue of the dead and the murderer, and the speed of role change seems to be too fast.

From the mouth of the female benefactor who lives in Ma Po Po Nunnery, it can be seen that Wang Hongbao's young and beautiful wife often helps men trim and polish their toenails, which is an important condition for comrades to find the deceased, but they did not expect to find the answer in Ma Po Nunnery.

But Wang Hongbao is still alive, and Qian Heping has already met Wang Hongbao - Ling Hu Yunfei and Ma Jianping have also met Wang Hongbao. Wang Hongbao and his wife wiped the floor between 11 and 12 o'clock in the middle of the night, why did they wipe the floor at this time?

Director Xu broke up with his comrades in Liuyedu, and after the breakup, Zhao Zimeng and his entourage got on Liu Asi's ferry.

Liu Asi was just about to set sail, when Xiao Lao suddenly said: "Zimeng, we should also go to the meditation room where Wang Hongbao and his wife lived." ”

Zhao Zimeng understood what Xiao Lao meant: "Go." Zhao Zimeng said as he jumped off the boat.

"Director Ma, you just got on the boat, why do you want to get off the boat again?" Liu Lao Sidao.

"Master Liu, thank you, let's go to Granny Ma's Nunnery."

Zhao Zimeng and his entourage strode along the river embankment to the back door of Ma Po Po Nunnery.

Director Xu turned around and followed.

The door of the nunnery is closed.

Director Ma knocked the door three times.

There was a quick reaction in the door: "Here it is—here it is." ”

Listening to the sound is a bit like Huihei Shitai.

After a while, the door opened, and it was Mrs. Huiping who opened the door.

"Mrs. Huiping, we also want to see if Wang Hongbao lived in the meditation room."

"Okay, wait a minute, I'll get the key."

Zhao Zimeng and his entourage went upstairs first, and the stairs were very simple, and people walked on it, even if their steps were very light, they could make a clear sound, and when they were more quiet, this sound would sound more real.

Before they had gone up to the second floor, they heard the sound of the door opening, the kind that occurs when the door shaft turns inside the doorway, which is both heavy and sharp.

Everyone walked up to the second floor and saw the female benefactor. She leaned against the doorframe, as if waiting for her comrades.

As soon as Zhao Zimeng's head appeared at the staircase, the woman greeted him: "Comrade Public Security, please come with me." ”

The woman must have something to say.

Zhao Zimeng, Xiao Lao and Ling Hu Yunfei followed the woman into the meditation room, there was a row of windows on the south side of the meditation room, and the light in the room was relatively dim.

The woman walked up to the bed, pointed to the floor next to the leg of the bed, and said, "That night, the sound of mopping the floor was in this position. After the woman spoke, she looked up at the floor, "I wiped it for a short time, at least twenty minutes." ”

The woman and Xiao Lao thought of coming together, and a person was cleaning the floor in the middle of the night, what would he wipe?

Footsteps sounded at the top of the stairs again, and after a while, Mrs. Huiping walked upstairs. She has a bunch of keys in her hand.

Everyone went up to the third floor with Master Ping.

Master Huiping unlocked the door and pushed open the door of the meditation room. The light inside the meditation room is dim.

There is a large bed in the meditation room, and the position of the large bed is the same as that of the female benefactor on the second floor.

Xiao Lao and Zhao Zimeng walked to the bed.

Lin Di pushed open all the windows, and Master Huiping turned on the lights.

The floor under the bed should be where the woman said it was.

Zhao Zimeng and Xiao Lao squatted on the floor, and the others stood behind.

Probably due to the passage of time, the surface of the floor has been worn out so badly that it has cracked in some places, and there are some long grooves in the joints between the floor and the floor. Is it any wonder that it takes a long time to mop the floor? No matter what kind of liquid it is, especially bloodstains, it won't be cleaned up without a few rubbings.

The woman also came upstairs, and she stood at the door of the meditation room.

"Is this the place to mop the floor?" Zhao Zimeng turned his head and beckoned to the woman.

The woman walked over to the bed: "Right here—right here." ”

Zhao Zimeng took the electrician's knife from the keychain and scraped the surface of the floor, the cracks of the floor, and the grooves of the joints one by one.

If Wang Hongbao and his wife wipe the blood stains on the floor, then it is difficult for them to wipe them clean, because the blood stains will penetrate into the cracks and grooves of the joints of the floor, and the blood stains on the surface of the floor are relatively easy to clean, while the cracks and grooves of the joints cannot be wiped clean. The reason why Zhao Zimeng scraped the cracks and seam grooves with the tip of an electrician knife was to see if there was any blood in the scraped powder.

There are places on the floor – especially cracks and grooves in the joints – that are rotting badly. Three minutes later, a small pile of powdery brown objects had gathered on the floor.

Lin Di took out a plastic bag from the bag.

Zhao Zimeng uses an electric knife to pinch the powder into a plastic bag.

Xiao Lao took the plastic bag from Zhao Zimeng's hand, put his nose to the mouth of the bag and sniffed it.

Everyone focused their eyes on Xiao Lao's face.

"Old Xiao, how is it?"

"Smell it." Xiao Lao handed the plastic bag to Zhao Zimeng's hand.

Zhao Zimeng sniffed, then handed the plastic bag to Ling Hu Yunfei, and Ling Hu Yunfei sniffed it and handed it to Xiang Daimo.

"It smells a little bit of blood." Xiang Daimo looked at Xiao Lao and said, "Xiao Lao, am I right?" ”

Xiao Lao, Zhao Zimeng, and Ling Hu Yunfei nodded at the same time.

There is a straw mat on the bed, Xiang Daimo uncovers the straw mat, under the straw mat is the bed board, there are three cracks in front of the first bed board, the color inside the crack is different from the color of other places, and the color inside the crack is a little black.

"Look—" Xiang Daimo said loudly.

Xiao Lao lifted the bed board, put the crack in front of his nose and sniffed it, then looked at Zhao Zimeng and said, "The smell of blood here is heavier, you smell it-"

Zhao Zimeng put his nose to the crack and sniffed: "There is indeed a heavy smell of blood." ”

Zhao Zimeng motioned to Yan Jianhua to open the mouth of the plastic bag and put it under the crack, and then slowly scraped the black substance inside the crack into the plastic bag with the tip of an electric knife.

In the process of Zhao Zimeng's scraping, two fat bed bugs crawled out of the crack, and common sense tells everyone that bed bugs are very interested in human blood. Bed bugs only like fresh blood, and once the blood clots, there's nothing they can do about it.

Xiang Daimo put the bed back in its place, and then spread the straw mat on the bed board, he put his eyes on the straw mat, what is Xiang Daimo going to do?

Since there have been people sleeping on this couch, there should be a few hairs left, if a few hairs can be found, plus the blood samples extracted, their DMA will definitely be detected, in the eyes of Xiao Lao and Zhao Zimeng, there must be some kind of connection between their DMA and the DMA of the deceased in the "6.27" headless case.

The light inside the room was too dim, and although the windows were all open and the lights were on, the light was still dim.

Xiang Daimo couldn't find hair on the straw mat - in the dimly lit meditation room, it was difficult to find hair on the straw mat.

"Zimeng, roll up the grass and take it downstairs to take a closer look." Xiao Lao Dao.

Xiang Daimo slowly rolled up the mat, held it in his hand, and walked downstairs, followed by the others.

Outside the round gate, there is a relatively wide blue brick road, there is no shade here, Xiang Daimo slowly unfolded the straw mat, Zhao Zimeng, Xiao Lao and Ling Hu Yunfei squatted around the mat, and soon, Ling Hu Yunfei found a hair on the head of the straw mat, this hair is relatively long, and this hair is wrapped around the joint of the straw mat.

Lin Di walked to Ling Hu Yunfei's side, she knelt on one knee on the straw mat, and slowly untied her hair, which was about thirty centimeters long. This is obviously a woman's hair, which is chestnut in color.

"This should be the benefactor's hair - her hair is so long, it's that color." Will level the master Taidao.

"Here's a few hairs." Xiao Lao found a few hairs on the other end of the mat.

Lin Di walked to Xiao Lao's side. Sure enough, there were a few hairs at the joints of the straw mat. Lin Di was not in a hurry, took out the hair from the joints of the straw mat one by one, and put them on a piece of paper one by one.

There are five hairs in total, the hair is thicker than the woman's hair, the hair is jet-black, and the length of the five hairs is about four centimeters.

"This is the hair of the male benefactor, and his hair is so long."

Xiao Lao put six strands of hair into a plastic bag.

Farewell to the Empress Dowager Huiping, everyone returned to the forensic office.

Xiao Lao and Feng Yiming immediately extracted samples from the deceased's body.

After extracting the sample materials, Zhao Zimeng immediately sent Ling Hu Yunfei and Lin Di to fly to Beijing with the sample materials.

It will take some time for the results to be identified, and all you can do is be patient.

In the afternoon of the same day, Zhao Zimeng, Xiao Lao and others went to the cofferdam dredging site east of Xihuamen and west of Liuyedu.

The dredging work in these two places is going on at the same time, the river has been drained, several large dredging machines are spraying black silt on the dredging trucks, and the sound of "rush-thud-thud" motors is incessant.

Zhao Zimeng did not have much hope for the dredging work, and the greater the hope, the greater the disappointment. It is not easy to find a head in such a large area of water, would the murderer hide the head of the deceased under the water?
