Mysterious case search [criminal investigation]

After walking around the community, the two went to the guard room. The guard room was quite large, with two desks by the window, and a row of filing cabinets by the wall. There were faded work rules and shift procedures on the wall. It can be vaguely seen the scale configuration at the beginning of its establishment.There is only one person on duty now, and a camera is set up beside the gate. Qi Chuchen knocked on the open door, and the guard turned his head, "Are you the police?"

The two walked into the guard room, took out their IDs and introduced themselves, "I want to come and get to know you a bit."

The guard nodded, "Is it because of Wudong, you can ask."

Zhang Chao started to ask, Qi Chuchen took out this record.

"What's the situation in your community? The old community or the family courtyard? Who usually live here now? How is the security usually? How many people are usually on duty at the gate?"

The guard took a sip of water from the big tea mug, and slowly began to tell about the situation in this community.

This community is a family home of a state-owned manufacturing enterprise built in the 80s. It belongs to the welfare housing, and the first people who live in it are the employees of the factory. In the mid-to-late 90s, the factory's operations went downhill until it went bankrupt a few years ago.Except for this family courtyard, all other places were sold out.Usually there is only one person on duty, and there are three guards in total, working in three shifts, and the law and order are quite good.

"We looked around and found that the outer wall was incomplete, so we just turned it in. There is no real estate, no security, and no cameras. You are only on duty alone. It is definitely impossible to patrol. How can security be good?" Qi Chuchen wondered. asked.

"Hey, it's because it's poor here! When the factory didn't work at the beginning, those who were capable went out to find another way to earn money and then moved out. The houses here are rented out, and the rent can't be much. Anyone who is willing to come here to rent They work at the bottom of the society. The old workers who still live here are old and nostalgic, and feel that old friends and old colleagues are together, and everything else is poor. Thieves will bypass this door, and the law and order will be better." The guard He took another sip of tea from the tea mug, and casually spit a piece of tea into the ashtray.

"Since this is the case, then there is no point for you to guard the gate. Who will pay you?" Qi Chuchen asked.

"Although the factory has collapsed, the family courtyard is still there, and there are still a few people in charge of assets. There are still parking spaces in this courtyard that can be rented out. We call it a gatekeeper. Basically, it is to control the entry and exit of cars and open the door to keep an eye on the cars. Don’t be stolen, most of our wages come from these parking fees. We used to be workers in the factory. The factory went bankrupt and laid off. We have no education and skills. Ah." The guard smiled wryly when he said this.

When Qi Chuchen and Zhang Chao heard this, they basically understood. No wonder there are no cameras here, and no one has repaired the walls. This is a slum in the downtown area.Thinking of this, Qi Chuchen still asked with an attitude of giving it a try,

"Did you see any suspicious people in the past half a month? For example, unfamiliar faces who came in and out in the middle of the night? Are you familiar with the male owner of that house in the fifth building?"

The guard shook his head, "I know his name is Long Xingmin, and he is also in this factory. It is said that he is very kind and kind, but he doesn't take the initiative to contact people. To tell you the truth, we are only open during the day on duty. For one's attention, the door is basically closed for sleep at [-] or [-] o'clock in the evening. Anyway, there are no cars coming in and out. If there is a car, you know how to honk. But I know that Lao Suntou seems to have a good relationship with Long Xingmin, and I often watch him play chess and drink together , but the old grandson has been away for the past few days, so he probably went out to play."

Qi Chuchen heard: "Do you know where the old grandson lives?"

"The third floor of the second unit of the eighth building, here, that's the one." The guard pointed.

The two bid farewell to the guard and went to the eight buildings to knock on the door. No one opened the door, and the other door came out and told the old grandson to go to his daughter's house in another place. He left before the National Day, and he should be back in the next two days.Qi Chuchen left his phone number and troubled the neighbors to let Lao Suntou contact him after Lao Suntou came back, so he left.

When going out, Qi Chuchen left a phone number for the guard just in case, please see Lao Suntou to inform, and then copied the surveillance video of the guard's room for nearly a month, although he knew that he found valuable clues The odds are low, but better than nothing.

After the two visited around, it was already past three o'clock in the afternoon when they drove back to the Municipal Bureau.

Zhang Chao went to the city bureau directly to the forensic office, please hurry up to do an autopsy and compare the DNA to confirm the identity of the deceased. . .Now we just have to wait.

Gao Rui ran up to Qi Chuchen's side in a thief-like way, twitched for a long time, and said in a low voice: "Brother, you are dressed like this today, and you drive a luxury car. Are you planning to go on a blind date?"

Qi Chuchen turned his head, didn't speak, and stared at Gao Rui expressionlessly. Gao Rui felt terrified after being watched, and couldn't hold back after five seconds, "Brother, I'll check the situation of the owner's daughter. I’ll tell you Ang when I’m back.” After speaking, he turned his head and ran away.

In the evening, the forensic doctor came up with a preliminary comparison result. The hair and other biological samples extracted from the pillowcase and bed sheet in the large bedroom at the crime scene were compared with the DNA of the deceased. At the same time, Long Xingmin's daughter had already arrived in Fengqi by plane. After receiving the news, the police took them directly to the police station for cell sampling, and finally confirmed the identity of the deceased again.

After finishing the sampling, Qi Chuchen took notes by the way.

The girl's name is Long Yalei, and she is very plainly dressed. Although she doesn't wear makeup, she looks quite beautiful.I am studying chemical engineering at a key university in Longdong City. My family’s financial conditions are not good. Tuition and living expenses are all dependent on my part-time work-study program, part-time jobs, and tutoring to earn money.It has been a long time since I have to work part-time.I borrowed money from the counselor to buy the air ticket back today.The inquiry was almost over, Long Yalei asked, "Can I go home? My mother must be very scared at home after this happened."

Qi Chuchen nodded and asked Gao Rui to drive the girl back.

After nine o'clock in the evening, the lights on the third floor of the Municipal Bureau were still brightly lit. The forensic doctor had just finished the autopsy and rushed out the report, bringing everyone together in the conference room to report the situation.The forensic doctor placed the slides one by one and began to explain the situation:

1. The deceased is 1 meters tall and weighs an estimated 71 kg.

2. The comparison between Long Yalei's DNA and the deceased's DNA was completed, and the probability of paternity reached 99.97%. The deceased was Long Yalei's father, Long Xingmin.

3. The freezing time is too long. At present, it can only be roughly determined that the death time is more than 7 days, and we are still trying to narrow the scope.

4. There is no life response in the dismembered body section, it is dismembered after death.

5. Judging by the contents of the stomach, he was killed 3-4 hours after dinner and had drunk alcohol before his death.

6. The cause of death was initially judged to be poisoning, and the specific poison and the way it entered the human body are still being tested.

7. When dismembering the corpse, there was no attention to the method at all, it was purely hacking and chopping.The wound on the deceased's body was judged according to the edge of the knife: two or more tools were used, such as a knife, machete, and chainsaw.Except for the chainsaw, the other two tools were recovered at the scene, and the blades were consistent with each other without fingerprints.

There is not much information, and every piece of information is critical. From discovery to report in ten hours, the forensic doctors really did their best.

After the forensic doctor reported, everyone began to ask questions, Zhu Zhen: "Which hand did the murderer use?"

Qi Chuchen: "Apart from the bathroom, is there any blood in the refrigerator?"

Luo Hao: "Are there any traces of other people at the scene?"

The forensic doctor synthesized everyone's questions, continued to play the slides, and told the situation.

"Apart from the deceased, Long Xingmin, the only fingerprint on the scene was that of Long Xingmin's wife: Liu Sulian. The fingerprints were mainly on the entrance door and the refrigerator, and others were not detected yet. We still haven't given up on the investigation, and we will repeat the investigation if necessary. Return to the scene of the crime. The murderer is right-handed. Regarding the blood stains, most of them are concentrated in the bathroom. There are but not many refrigerators. We speculate and analyze that the murderer is likely to wait for the flushing process after the body is dismembered in the toilet, etc. After most of the blood flowed out and was washed away, it was stored in a basin in the bathroom and stored in the refrigerator, so there was basically no blood stains outside the bathroom."

"How long will it take to wait for most of the blood to flow out?" Zhang Chao asked.

"The cutting method and the washing method both affect it. Theoretically speaking, it takes at least 10 minutes. We found no corpse spots in the frozen part, which means that the time from the death of the deceased to entering the refrigerator should not exceed two hours at most," the forensic doctor replied.

"That is to say, the murderer spent at least half an hour after killing the person, cut it into small pieces, washed it clean, put it in a basin and put it in the refrigerator." Qi Chuchen said.

The forensic doctor nodded, indicating that this understanding is no problem.

Everyone looked at each other, exchanged in low voices, and said that there were no new problems for the time being, so the forensic doctor packed up the materials and went back to speed up the inspection.Zhang Chao began to arrange work, and continued to screen Long Xingmin's social relations the next day, investigating the recent activities of Xia Long Yalei and Liu Sulian.Then I announced that I would call it a day and go back to rest. There will be a long time to work overtime in the future, so hurry up and recharge your batteries.

After the meeting, Qi Chuchen went back to the office and checked his phone. Yan Mu sent a message after seven o'clock. He was too busy to look at his phone. Seeing this, he quickly replied: "I just finished my work and I'm ready to go home." Then Throw the phone into the drawer and enter Zhang Chao's office.

"I think there's something a little strange."

Zhang Chao glanced at him, his eyes seemed to say that the most strange thing is that you are dressed like this today, "Huh? Tell me, what do you find?"

"When the little girl Long Yalei came to the bureau in the afternoon, I found that she was too calm and didn't have any sad emotions. She didn't even care whether her father died or not. This is a bit abnormal." Qi Chuchen said from Zhang Chao He took out a cigarette from the cigarette box on the table and lit it for himself.

Zhang Chao glanced at him angrily, "Do you suspect Long Yalei?"

"No, I just think that their family relationship might be a bit discordant? Anyway, it's definitely not normal. I'll go to their family courtyard tomorrow to inquire. I don't know if the old grandson has come back." Qi Chuchen's last sentence was like It's a soliloquy.

Zhang Chao flicked the smoke in front of him with his hand, "MD, I'm using this as a smoking room, get out as soon as you finish smoking, I can't smoke for the past two days with pharyngitis and I've been poisoned by you bastards."

Qi Chuchen put out his cigarette butt, ran back to his seat with a smile, looked at his phone, the latest WeChat message was half an hour ago, and half an hour passed before he knew it.Open WeChat to see,

"Didn't you have dinner, do you want me to pick you up?"

Qi Chuchen hurriedly replied, "No, you have a good rest." After answering this, Yan Mu didn't reply, Qi Chuchen continued to open the forensic report, and the on-site information looked like it.
