Xiao Ran chuckled and shook his head, and said, "Brother Zhang, I also just came over, how can I know everything?" I just listened to their discussions before, plus these supplements you said, so I have this judgment. ”

Zhang Hui grinned, "Yes, we are all human." ”

Xiao Ran nodded slightly, and said: "But I want to go to the scene of the '7.28' case now, and then go and talk to Cheng Yuguo, can you find someone to take me over?"

"Yes, no problem. Zhang Hui said decisively.

Immediately called a young female internal officer, named Yu Mengqing, with ordinary height and relatively handsome appearance.

"Xiao Yu, this is Xiao Ran and Zhang Lei, they are all from the city bureau to help, you take them to the '7.28' site first, and then go to the detention center to mention Cheng Yuguo. ”

Yu Mengqing nodded in response, staring at Xiao Ran for a long time before she asked Zhang Hui, "Boss, this is what you said before, the fastest man in our city?"

As soon as the words fell, Zhang Lei couldn't help laughing, hurriedly glanced at Xiao Ran, and immediately put away the evil smile on his face.

Xiao Ran turned his head to look at the side calmly, the fastest man in Lin'an City...... Can adding two more words to describe it exhaust to death?

"Hello, I'm Xiao Ran. ”

"Hello Team Xiao, my name is Yu Mengqing...... Wow, your hands are so slippery, your skin is so good, it's better than my little cousin's ass to the touch!"

Yu Mengqing took Xiao Ran's hand, looking left and right very strangely.

Xiao Ran withdrew his slap that could kill a pig in a flash, and smiled hard: "The case is urgent, let's take us to the scene first." ”

"Okay, you go downstairs and wait for me first, and I'll sign two certificates. ”

It didn't take long for Yu Mengqing to run down from upstairs, beckoned Xiao Ran and Zhang Lei to get in the car, and then drove towards Cheng Yuguo's home.

Yu Mengqing's driving skills are very good, on the road where pedestrians don't look at the traffic lights at the junction of urban and rural areas, the driving is still very smooth, not as vigorous as when Yu Yu holds the steering wheel.

On the way over, Xiao Ran was also observing the surrounding environment, he had been to Chengdong District before when he was handling Guo Yilei's case, but the place he went to was still some distance away from this area, and he didn't go from this side at that time.

The environment is similar to the previous Guo Yilei case when Zheng Huanju was arrested, the place under construction, the relevant infrastructure is not complete, and the mobility of personnel is large, which often brings chaos.

The car turned into a small road from the main road, turned a few more corners into a relatively narrower road, and stopped in the middle of the road, a two-story self-built building without a yard on the right hand side was the first scene of the '7.28' case.

Due to the rain that had just fallen overnight, there was still a muddy puddle on the road in front of Chengyu Country, and the stone-paved road was still wet, Xiao Ran looked at the two footprints behind him.

The gravel road is not like the asphalt road, cement road, and dirt road, which is a pavement composed of stones, with many gaps and unfixed structures, although it is easy to leave traces, but it is easy to disappear after being washed by rainwater.

As recorded in the investigation report, the traffic around Chengyu country is indeed complicated, and there is no monitoring equipment, if you want to know more, in addition to the remnants of the scene, you can only rely on the strength of the masses, maybe someone saw the murderer that day.

However, after nearly half a month of visits, the Chengdong Branch did not find any witnesses, and there were few traces of the scene.

At this time, it was close to noon, and many people were already preparing lunch, and when they saw a police car parked at the gate of Cheng Yuguo, the idle crowd around them surrounded them one after another, and kept asking, did Cheng Yuguo kill his wife?

"Little comrade, you have to work harder, there is no truth here, we don't dare to go out at night, as soon as it gets dark, we quickly lock the doors and windows, and we don't worry about this, and we have to find a wood to hold the door from behind. ”

Several aunts kept chattering to Xiao Ran: "It's really scary, you don't find out the murderer, it's really scary, I heard Cheng Yuguo's voice at that time, go in and take a look...... Now that I think about it, the flesh on my body hurts so badly, it's so miserable, it's really cruel, the children are scared stupid!"

Xiao Ran was pulled by uncles and aunts, so many people you say yours and I will mine, Xiao Ran was dizzy when he listened.

finally saw the opportunity, and hurriedly shouted: "Uncles and aunts, don't worry, there will be results soon, okay, we want to go in and have a look now, everyone support our work, okay?"

"Okay, okay. ”

The surrounding crowd quieted down, but when Yu Mengqing really took the key and opened the door of Chengyu Country, the people at the door immediately disappeared again.

After all, in the eyes of the masses, where people have died, there are still people who have died in vain, and deep down they are always reluctant to come into contact.

Put on shoe covers, Xiao Ran and Zhang Lei followed Yu Mengqing into Cheng Yuguo's home, because the curtains were closed, and it was rainy weather, the house looked a little gloomy.

As soon as he entered the door, the first thing Xiao Ran saw was the large splattered blood stains on the floor, TV, and walls, as well as the large dark brown blood stains on the sofa.

Needless to say, the splattered blood stains were sprayed after the deceased's throat was cut, and the large blood stains on the sofa were infiltrated by the corpse when it was on the sofa.

The frictional blood stains next to the large blood stains on the sofa were left by the murderer when he violated the deceased at the end of his life, or after the deceased's death.

Flipping through the folder, through the photos taken by the technicians when they fixed the scene, coupled with the blood stains that were still well preserved at the scene, Xiao Ran seemed to see the situation when the murderer committed the violence at that time.

"Hey, Xiao Ran, you see, the crowd reported that after the deceased's family quarreled at around 10 o'clock, there was no sound. ”

Zhang Lei turned on the ultraviolet lamp in his hand, observed the scene and asked: "If a stranger had broken into the house at that time, the deceased Li Lu would have shouted, but the surrounding people did not hear the movement." - Could it be that an acquaintance committed the crime, or maybe it was Cheng Yuguo who committed the crime, after all, only familiar people come in, and people will let their guard down, right?"

Xiao Ran looked at Yu Mengqing.

Yu Mengqing replied knowingly: "We must investigate these, the surrounding people, Li Lu's acquaintances, relatives and friends, Cheng Yuguo's acquaintances, relatives and friends, we have all checked it, although there are physical characteristics, but we can't determine whether they are suspects." ”

Xiao Ran said: "Then trouble Sister Yu to go back, show me the information of those people who have been investigated." ”

"Okay. Yu Mengqing nodded in response.

Xiao Ran didn't say any more, and continued to flip through the folders, comparing the scene investigation records at the time, and reconstructing the situation after the murderer's murder in his mind.

The autopsy report stated that the inside of the deceased Li Lu's lips was cracked, apparently caused by the murderer vigorously covering his mouth and nose.

Therefore, if the murderer is a stranger, he restricted Li Lu's voice at the first time, and it is not impossible for him to do so.

Xiao Ran held the folder and walked around the first floor.

However, when Xiao Ran opened the bathroom door of the deceased's house, his eyes were suddenly attracted by a trace......
