crime scene

After coming out of Yu Sangsheng's house, he didn't return to the police station, but went around and around to Lu Wei's house.

Sun Yaoguang parked his car at the door of the bungalow he rented in the village in the city, and it would be inconvenient to drive further inside.

Sun Yaoguang stopped and walked, asked around, and finally came to Lu Wei's house.

The door was unlocked and ajar. Su Nianyou observed that every household here did not have the habit of closing the door during the day.

There was a heated kang in the house, and a coffee table was placed on top of the kang. Liquor bottles and beer bottles were placed on the coffee table in an unruly way, and some fell on the ground.

Xie Qian looked around, there were only a few clothes in the closet, and there was nothing valuable if there was a TV and computer at home.

The good news is that Lu Wei's mobile phone is on the coffee table. You must know that most murder cases are successfully solved due to the call records of the deceased.

Sun Yaoguang took out the evidence bag and put it away.

Xie Qian took a closer look at the ashtray.

"It seems that there is only one person, and the direction of the cigarette butt is almost to one side."

Su Nianmo counted the number of wine bottles.

"Nine bottles of beer and two bottles of white, drinking so much wine alone...it seems to be drinking to drown your sorrows."

"When we came in, wasn't there a small shop at the door, go and ask?" Sun Yaoguang said.

"Go." Xie Qian lifted his buttocks and sat down on the hot kang.

Sun Yaoguang was stunned for a long time, and the last person went to visit the canteen pitifully.

Su Nian sat beside him,

"Any ideas?"

Su Nian shook her head, "There are too few clues at the scene, and we haven't done enough research on the victim, so it's difficult to make portraits at the moment."

Psychological profiling, the more perverted it is, the easier it is, and it is generally difficult to speculate on personality traits.

"No idea at all?" Xie Qian asked, lighting a cigarette.

Su Nian was a little hesitant and didn't speak for a long time.

"Nian Nian, say whatever you think, it doesn't matter if you're wrong."

"Because this is not a discovery, it's just a personal feeling. Assuming that the person Lu Wei was going to kill that night was Yu Sangsheng, but judging from the situation in the house, he must have struggled for a long time before going out. He was struggling and drank a lot of wine to build up his courage."

"The question comes back to why he killed Yu Sangsheng." Xie Qian added, "Is it because... Yu Sangsheng blocked other people's money, and someone hired Lu Wei to kill him?"

Su Nian nodded, "It's just a feeling. The information I have is too little to be considered as inductive reasoning. Lu Wei may be carrying a knife for self-defense."

"Whether it's for self-defense or something else, a knife is a sharp weapon for hurting people." Xie Qian said as the phone rang, it was Chu Duanyu.

"Captain, the deceased's urine test was positive. He took drugs and had a lot of alcohol in his system. The drug that the deceased carried with him was cocaine. In addition, a set of DNA was detected on the blade. I am doing a comparison. Captain, when are you coming back?"

"It will take a while. I will work overtime tonight. Eat first when you are hungry."

"Oh…"

Xie Qian hung up the phone, he heard the strong sense of resentment from Chu Duanyu's tone, what's going on?It's not just overtime, it's not that I haven't worked overtime.

"The captain has the result, the result is the result!" Sun Yaoguang walked in from the outside and sat on the heated kang. "The aunt at the small shop said that last night, that is, around 9 o'clock in the evening on February 10st, Lu Wei bought it from the small shop. A box of wine, before the canteen closed at ten o'clock in the evening, he returned the wine box, and his aunt gave him a deposit of [-] yuan. Aunt Gu recalled that he was quite drunk at the time, and the neighbors also said that Lu Wei was usually white The foreign beer is always welcome, and it is quite drinkable.”

"How much is ten o'clock?" Xie Qian asked with a frown.

"Auntie said she couldn't remember clearly, it should be a little before 10:30..."

Xie Qian lit a cigarette, exhaled the smoke slowly, and looked at Su Nian.

"How did he walk from here to the road in half an hour? It's too far away."

Su Nian also shook her head to express that she didn't know.

"Okay, let's go back to the team first."

It was past six o'clock in the afternoon when we drove back to the urban area, just in time for the evening rush hour, and people in traffic jams had a headache.

Fortunately, Sun Yaoguang is calm enough to maintain a good mentality in this situation. If it were Qian Qian who drove the car, the horn would probably be blown.

At this time, the distraught Captain Xie was eating candy to relieve his emotions.

"Nian Nian, let's run back to the police force." Xie Qian suggested.

"...you are so irrational when you are upset."

Nonsense, show me some reason when you are upset?

Xie Qian stretched out his hand to ravage his head, but rubbed it vigorously, it was time to relax his body and mind and relieve his irritability.

Su Nian fixed his hair impatiently over and over again, and Xie Qian also rumpled his hair again and again impatiently.

Sun Yaoguang looked at his captain through the rearview mirror, very speechless, and couldn't find any adjectives to describe his extremely complicated heart at this time.

After finally returning to the police force, the first thing Xiqian did when he got off the car was to buy food, but Sun Yaoguang felt aggrieved and had to eat instant noodles.

The conference room is really a good place to eat and sleep. The short-legged cat that was fed into a ball by the police force was sleeping soundly on the table.

"Ah, I ate another cat hair!"

"Chu Duanyu, shut up!"

"Cut. Don't act like I don't..."

How to eat and eat cat hair is still a very honorable thing...

Su Nian sat on the side and supported her forehead, always feeling that this group of people is becoming more and more abnormal.

"Niannian come to eat."

What Xiqian bought back was the Lanzhou ramen across the road. He also brought back special vinegar for Ergu steamed stuffed buns.

Su Nian loves to eat noodles, especially with a lot of vinegar added to the noodles, so Xie Qian would occasionally tease him for being "jealous".

There was a small meeting while eating, and Xie Qian sorted out the case and sorted out doubts.

Chu Duanyu's report from the forensic department had explained the main points on the phone, so he shut up and listened to other reports seriously.

"The DNA identified on the blade does not match the deceased. We don't have a complete database. It is not clear who this set of DNA belongs to." Jiang Panpan had finished his dinner and was reporting while eating an apple, "The other one The small packet of cocaine contained 50 grams, and the sample was of moderate precision and purity."

"The trace inspection found a small amount of soil on the sole of the deceased's shoe. I have collected soil samples from nearby areas, and I am doing acid-base tests and similarity comparisons." Zhang Yitian poked the steamed buns with chopsticks and dipped them in the vegetables in Jiang Panpan's box lunch The soup is eaten bit by bit.

"Oh, I went to the telecommunications bureau and retrieved the call records of the deceased for nearly a month, ticked off a few key numbers, and compared them with the contact list of the deceased's mobile phone later." Feng Li said.

"What's the price of cocaine now?" Su Nian asked

"Hundreds, maybe..." Zhang Yitian replied, "It was hundreds in the past two years, and it's too clear that I haven't received any related cases recently."

In this meeting, Su Nian surprisingly said very little, and Xie Qian didn't ask too many questions. After the meeting, he got off work and drove home directly.
