Officer Cao and a team of police officers rushed to the warehouse on the outskirts of the city, which was located at the foot of a barren mountain, and was supposed to be built privately to store things. The warehouse is about 30 square meters, empty, no old things have been piled up, and there is not much dust on the ground.

The striking thing is that the northwest corner near the window is fenced with iron sheets. The tin sheet and the surrounding walls were smoky and mottled with black and mottled marks, and the forensic team collected the ashes of the incineration.

"Have you contacted the owner of the warehouse?" Officer Cao asked

"I've already come over, surnamed Wang, 65 years old, Xu Ran is making notes," Xiao Wang replied.

"Surname Wang?" Officer Cao looked out of the window of the warehouse. Opposite Xu Ran was an old man with gray hair, nodding and cooperating.

The officer walked quickly out of the warehouse and walked towards them.

"Hello, Uncle Wang, I'm Officer Cao"

"Oh, Cao, Cao, Officer Cao, good, good" Uncle Wang, in a hurry, stammered,

"Uncle, don't worry, speak slowly," Xu Ran said with relief on the side

"Oh, Xie, Xie, thank you, Xu, Xu, Xu, police, police, officer" Uncle Wang became more and more anxious, and the more he couldn't speak.

Officer Cao turned his head and asked Xu Ran: "The agreement was obviously signed by Zhao Kaifu, why is the owner of the warehouse Uncle Wang?" ”

"Team Cao, Uncle Wang has never rented out a warehouse, and he doesn't know this Zhao Kaifu. This warehouse has been idle for a long time, and some old furniture is piled up, Uncle Wang's legs and feet are not good, and he doesn't live close, so he hasn't come to see it for more than half a year. Xu Ran replied

"Yes, yes, yes, no, don't recognize, know, what, Zhao, Zhao, Zhao Kaifu. Officer Cao, Officer Cao, I, I, I, what, nothing, no, no, I don't know" Uncle Wang eagerly defended.

The warehouse stores old furniture, and no one has taken care of it for half a year? What about the old furniture, burned or transferred? The trace examination department also found no footprints on the floor of the warehouse! The lease agreement was signed by Zhao Kaifu, and there was not even a copy of the ID card attached to the back of the agreement. So what is the intention? So that we can find this warehouse? Officer Cao's expression slowly became solemn.

"Officer Cao, Uncle Wang's transcript is finished, I'll go over there to help" Xu Ran's face was clouded, and he ran to the warehouse as soon as he slipped away.

"Hey, I'll tell you, it's not right today, you all be careful," Xu Ran whispered.

"Needless to say, it's seven days to solve the case, it's a lot of pressure," Xiao Wang said

"It's not like the murder and cremation sites have been found, a major breakthrough," Xiao Liu said.

"Okay, let's get to work" Xu Ran glanced at Xiao Liu.

At the end of the on-site investigation, the team returned to the police station to hold a case analysis meeting.

"The forensic team carried out laboratory tests on the ash from the on-site incineration, which confirmed that it contained human tissue and clothing fiber incineration residues. Through the bloodstain detection agent on the warehouse floor, it was found that there was a large area of blood stains on the warehouse floor. After taking and testing, it was confirmed that it was Zheng Jun's bloodstains. It means that this warehouse is the scene of the murder and cremation," Officer Cao was the first to speak.

"Sure enough, as soon as I looked at the corner of the warehouse, I felt that I had found the right place" Xiao Wang looked proud and whispered to Xu Ran next to him.

"......" Xu Ran glared at Xiao Wang, thinking to himself, you have solved the case, you have caught the murderer, look at you proudly. I can't help but recall the solemn expression of Team Cao outside the warehouse, it seems that this case is not so simple.

Police Officer Liu of the forensic medical team said: Zheng Jun's cause of death was intracranial hemorrhage caused by blunt external force on his head, and from the analysis of the skull fracture and the impact point extract, the murder weapon was an iron weapon with edges and corners. The scene of the murder was cleaned and no footprints were found on the ground. No murder weapon was found at the scene of the murder and cremation, nor were the fingernails removed. ”

Why did Zheng Jun go to such a remote warehouse, and who did he meet? It should be a familiar person, otherwise why make an appointment with a stranger in an unfamiliar place? Don't think about personal safety? Unless this will be very important to him. Officer Cao pondered in his heart.

"What are the results of the camera records around these three locations?" Officer Cao asked

"The village where the warehouse is located is very remote, there are no cameras, only there are cameras on the national highway three kilometers away from the village, and the vehicles that have passed by in the past month are being checked, and Zheng Jun's vehicle has not been found. The video data recorded by the camera at the entrance of the Lido International Community and the camera around the place where the body was dumped did not duplicate the vehicle," said Officer Li of the Technical Department

"Lido International belongs to a high-end community, in addition to the camera at the entrance of the community, there is monitoring at the door of each unit, and there is also monitoring on each floor. However, the monitoring of the community can only store seven days of video data. According to the video records of two cameras at the door of the unit and on the 16th floor, room 1602 has only one courier from a courier company to deliver the parcel in the past week, knock on the door, make a phone call, and then leave. In addition, the security guard of the building took a person from floor to floor to collect garbage bags. Officer Lee added.

This courier is called Wang Xiaoshun, who has worked in the company for more than a year, and goes in and out of the community every day to deliver couriers. The person who collected the garbage bags was the security guard in charge of the building, surnamed Wang, who also reported the case, and the garbage was collected with another security guard and did not enter the room. is right with the transcript," Xiao Liu took it immediately.

"It is worth mentioning that the parcel delivered by the courier Wang Xiaoshun on the same day, we took it to the police station as evidence, opened it and saw that it was a box of HIV test strips, the order time was three days before death, and the goods arrived in a week, and Wenwen had died four days when it was delivered." Xiao Liu added.

As soon as everyone heard that it was an HIV test strip, they began to whisper.

"My private life is so messy, I'm afraid I have AIDS, let's kill people to vent my anger"

"So, beautiful girls must know how to protect themselves," Xiao Liu said, and glanced at Xu Ran secretly.

"But Li Wenwen's autopsy report did not detect AIDS in her blood," Xu Ran asked puzzled.

"Yes, Li Wenwen is not infected with AIDS," Officer Cao replied.

"Team Cao, could it be that Li Wenwen suspected that Zheng Jun had infected herself with AIDS, and the two clashed, killed Zheng Jun by mistake, and then committed suicide?" Xiao Liu suddenly burst out with a sentence.

As soon as Xiao Liu finished speaking, everyone burst into laughter, and Officer Cao glanced at Xiao Liu: "A girl in her twenties, weak and slender, how can she kill Zheng Jun and go to a warehouse so far away to kill?" And how do you throw away the corpse without leaving a trace? ”

"Maybe it's because Zheng Jun doesn't want to leave ......" Xiao Liu was choked by a series of questions, a little embarrassed, the more he spoke, the quieter his voice became, and finally he simply swallowed the second half of the sentence back into his stomach.

"It makes sense to kill love, but it's enough to kill Zheng Jun, why do you have to go to great lengths to burn the corpse and pull out your nails?" Xiao Wang asked puzzledly, obviously this motive for killing is not valid.

"We checked the membership card associated with Li to Wenwen's mobile phone number at Wumart Supermarket, and the shopping records showed that ten days before her death, Li Wenwen bought enough food for a week and spent 623 yuan. And Li Wenwen died three days later, it is impossible to eat all these foods, there should be more than half left, but no food was found at the scene.

In addition, it was found that the deceased went to the ** hospital in our city a month and a half ago for treatment, and made an appointment with the number of Dr. Xu Min of the Department of Neurology, who is good at the diagnosis and treatment of depression. Dr. Xu said that Li Wenwen came to the clinic alone that day, she said that she was always depressed recently, she collapsed at every turn, cried, and slept badly, Dr. Xu judged that she did have a tendency to depression according to her situation, and she did not use medication, so she explained to write about emotional control and precautions, and asked her to return to the clinic in a month, and she did not go to the follow-up clinic again," Xiao Wang said.
