Xiao Ai told Mr. Shao the current address of Wei Qian. Xiao Ai once heard Wei Qian say that when she was a teenager, her parents divorced, and she now lives with her mother. It only takes about an hour and a half to drive from this address. Everyone said goodbye to Xiao Ai and went to Wei Qian's house.

This is an old open-plan community, and the property managers have long gone, and paying electricity and water bills has become a task for the residents themselves. There are no cameras in the old corridors, the houses are dilapidated, and the flow of people is mixed. In the area of ​​Longcheng, the rent for a room here is no more than 300 per month, which shows the dilapidation here.

Xu Yiman parked the car, and everyone came to the fifth unit. Unit 5, the sixth floor, is the highest floor. And Wei Qian's house is at 602 on the sixth floor of Unit 5. Standing at the door, only the door frame of the dilapidated building door is left, and the iron door has long since disappeared.

The corridor was full of old and shabby items such as cardboard boxes and iron buckets. A bicycle that had fallen apart was leaning on the side, and it seemed that no one had ridden it for decades. The stairs were covered with dust, leaving countless footprints of residents, and it seemed that no one had ever cleaned the place.

There was no elevator, so a few people climbed the stairs and went all the way to the sixth floor.

All the way up, looking at the left and right doors all the way, most people do not have anti-theft doors, and some even have locks. This ancient way of locking the door and the mottled and cracked walls are telling everyone that the buildings here are almost a hundred years old. Some of the doors have been cobwebbed, and it looks like no one has lived in them for a long time.

The doors of the houses were closed, and it was unknown which houses had residents, and which houses were already empty.

The door of 602 was also closed, but the floor mats in front of the door were spotless, which means that someone cleaned it here.

Jiang He stood on the foot pad and knocked on the door "Dong Dong Dong": "Wang Ziyi, is Wei Qian at home? We are the police, let's find out something."

But Jiang He shouted for ten minutes, but there was no movement inside. Xu Yiman was also constantly calling Wang Ziyi or Wei Qian's mobile number, but no one answered either.

At this time, a "squeak" came from behind several people, and an old voice asked, "Who are you looking for?"

Looking back, the resident of 601 was a white-haired old lady who seemed to be in her 70s or 80s. He leaned on a cane and asked tremblingly.

"We are looking for Wang Ziyi from 602, her daughter is Wei Qian, do you know?" Shao Lao said.

"Selling fragrant rice? Fifty cents?" the old man asked with a frown.

Shao Lao raised his voice again: "Wang Ziyi, it's not selling fragrant rice!"

"What?" The old lady moved her ears forward, but still couldn't hear clearly.

Shao Lao was helpless. He pointed to the door of 602 and asked, "This family!"

The old lady seemed to understand something, nodded and said: "Last night, the couple quarreled. I heard the war inside, crackling, men scolding women, women scolding men, and the sound of broken glass. After a while, there was no movement, I watched the door open, and a man went downstairs and left."

Several people immediately became alert. After Wang Ziyi and Wei Lingyong divorced, the information showed that she did not marry again, and Wei Lingyong had no idea where his wife lived. How could he come here to quarrel with Wang Ziyi? ? So who was the one who quarreled with Wang Ziyi last night, and where did Wei Qian go last night?

"Could it be Lu Zhengye!" Shao Lao thought to himself.

"What sound did you hear?" Elder Shao raised his voice, basically shouting.

The old lady said: "Why are you shouting so high~ I can't hear you. Last night, I was lying behind the door and listened. The man said he wanted to eat jujube kernels, and he said about eating rice cakes. Wang Ziyi said she didn't. After eating rice cakes, she said what **** tea to drink. She really liked **** tea and called it many times. The man said he didn't drink **** tea, and also asked Wang Ziyi to buy some wife cakes. …”

Saying that, the old lady laughed: "His family loves it."

Hearing this, everyone was really helpless. As long as there is no problem with the brain, there will definitely not be such a quarrel over what rice cakes and **** tea to eat. Besides, I don't know who likes to eat it, sometimes it sounds like fragrant rice, and then it sounds like wife cake. I don't know if the old lady's ears are working well.

"What's that guy like?" Shao Lao asked.

The old lady turned her head sideways, as if she didn't hear clearly: "Ah? Old goat? Old goat is not delicious, but roast lamb is delicious."

"I said what that man looks like!" Shao Lao shouted again.

"What are you shouting, what are you shouting!" The old lady rubbed her ears: "You screamed my ears to death! That man has fat arms, big ass, dark skin, and a round head. Yes, tall and fast walking."

This description is similar to Xiao Ai's description. If it is really Lu Zhengye, Wang Ziyi is afraid that it is in danger.

"Okay, old sister, go home and rest first." Shao Lao said while helping the old lady to go home.

"Oh, Sheep Scorpion?" The old lady said as she walked home, "Sheep Scorpion is ready to make soup."

Saying that, the old lady opened her mouth wide and said, "The sheep and scorpions have so many bones that I have lost all of my teeth, and I can't chew them, hee hee."

She is the only one in the old lady's house, but her ears are not good, her mind is still clear, and she is not too confused, and the house is clean.

After Shao Lao came out, Xu Yiman couldn't help laughing: "This grandma is so cute."

"Is it cute?" Shao Lao shrugged: "I won't be like her in the future, I know how to eat in a day..."

"Don't talk about that." Elder Shao said to Jiang He, "Do you think this lock can be opened?"

Jiang He walked over, observed the keyhole for a few minutes, and said, "It's not a big problem."

As he said that, he found a thin wire from the debris on the side. He folded the wire into two sections, and then folded a section of the wire in half, and then it was all inserted into the keyhole. After fiddling for about a minute, the door "slammed" With a bang, a gap was revealed.

As soon as Mr. Shao entered, he smelled a familiar smell.

"Xu Yiman..." Shao Lao said.

Before Shao Lao had finished speaking, he heard Xu Yiman say, "I smell it, the smell of blood, and the special smell of corpses."

Yes, there is a body on the ground. The corpse was lying beside the coffee table, she was lying on her side on the ground, and a vast pool of blood had already solidified and turned dark red. On the coffee table, on the wall beside the coffee table, a puddle of blood sprayed like someone splashed ink, covering half of the wall.

The blood on the wall has also coagulated at this moment, but before the blood did not coagulate, it used to flow down the wall slowly, like small snakes winding down. Some of these little snakes are long and some are short, with twists and turns.

Jiang He carefully observed the room, and heard the grandma next door say that she once heard the sound of glass breaking. But Jiang He didn't see the scum of broken glass on the ground. He took a quick step and saw a shard of a glass in the trash can.

That is to say, after the quarrel, someone picked up the broken glass.

Xu Yiman had already started examining the corpse at this time. She took out white gloves from the bag she was carrying, and gently touched the skin of the female corpse with her hands.

"It's Wang Ziyi, that's right." Xu Yiman saw Wang Ziyi's face, which was exactly the same as in the photo.

"Slightly squeezed the corpse corpse spot, the corpse spot faded slightly, but the original corpse spot did not disappear, which means that the corpse spot is in the diffusion stage. The wound on the neck has a reddish liquid overflowing, which is not easy to wipe off. The stiffness was severe, the jaw joints were rigid. The corneas of the cadavers became cloudy and slightly folded. The muscles lost their hypersensitivity.”

At this moment, Xu Yiman's white gloves were covered with sticky, pale red or even yellowish tissue fluid. She said to Jiang He, "Take out the tweezers from my bag. My gloves are too dirty."

Jiang He nodded, and turned it around in Xu Yiman's bag. Jiang He found that Xu Yiman's bag basically had no women's products. Except for the kind of women's special items, there were no cosmetics, no lipstick and eye shadow. messy stuff. This reminded Jiang He of the first time he saw Xu Yiman. Indeed, Xu Yiman never wore makeup, whether at work or in everyday life.

In Xu Yiman's own words, cosmetics will affect the identification of the scene, such as chemical elements, such as smell, so she never wears makeup.

Her bag contained some gloves, some evidence bags, a mask and small anatomical tools.

Jiang He also took out a pair of gloves and put them on. Then he found tightly wrapped tweezers in his bag and handed them to Xu Yiman.

Xu Yiman took the tweezers and squeezed out a tiny white thing from her neck. Jiang He looked closely and saw that it was a white maggot.

Xu Yiman said: "In autumn, it is estimated that the flies that survived will find the corpse in about half an hour and start laying eggs in the corpse. The conditions here are simple, and flies can easily fly in. In about ten hours, the eggs It can hatch into maggots. You can see that this maggot is still very small, which means that it has just been born. There is no pupa around it, which means it is a generation of maggots."

"Let's look at it based on the old lady's confession." Xu Yiman gently took off his gloves and put them aside: "Ziyi Yi died for about seventeen hours, so push back, that is, ten o'clock last night. Between eleven o'clock."

"As for the cause of death, it should be the wound on the neck." Xu Yiman continued: "The wound is deep, about five centimeters long, and the **** are neat. It should have been caused by a commonly used Western-style kitchen knife. The murderer cut her neck directly. Arteries, all the blood sprayed on this wall. I think in about a minute or two, Wang Ziyi was dead."

"But there is no that knife around." Jiang He said, "I just observed the house carefully, where did the knife go?"

Mr. Shao said: "Immediately arrange for the criminal police of the technical department to come to investigate the scene. Xu Yiman, you go back and make a detailed autopsy report. Jiang He and I still need to visit and investigate, especially the old lady who heard the quarrel last night. Maybe she He is the only witness who has witnessed the murderer!"

"clear."
