According to the preliminary investigation results, the deceased's name is a makeup beauty, 34 years old this year, the proprietress of a cosmetics store, and her husband is a senior team leader of a toy factory, named Wu Dazui, male, 36 years old this year.

The deceased died in his own house, the informant was his husband, he came home from work, ready to go to the cosmetics store to pick up his wife, I didn't expect it, I didn't receive anyone, I didn't care too much about going home directly, it is estimated that she has gone home, but when he arrived at home, he saw his wife dead at home, he looked at the body, it was really dead, scared him to call the police immediately, the ace is thinking about this problem, that is to say, usually the husband gets off work and then drives her home, but how to go home early on the day of the crime, And he didn't call to inform his husband, but let him run for nothing.

Wu Dazui did not return home until about 7 o'clock in the evening, and left the house with his wife at 7:40 in the morning, from here to see that the time of death of the deceased was not long after.

Ace arrived at the scene, in the night they saw a six-story building, the crime scene was on the fourth floor, the structure of the whole building is like this, the owner of the building is six brothers, the parents left this house, divided it to six sons, each son has one, the deceased's family lives on the fourth floor, the area of the whole building is about 200 square meters, Ace and Jinshan and a few policemen went up to the fourth floor, this building has no elevator is walking up, the door of the scene faces west, the door is a red wooden door, the structure of this house is a rectangular structure, At the end of the rectangle, I saw five red wooden doors, and five windows, and I could see the high ground when I looked down from the corridor, and there were five windows on the back wall.

And the layout of the room is even more frightening, so many doors a total of 200 square rooms, since there are ten single rooms, divided into five groups, a group of two, divided into five groups, the deceased died on the sofa in the living room, and the five groups of rooms have a door to lead, if this case is a special case will be troublesome, so many rooms to find out when, too many doors for fear of some details missing, specially called a few professional police officers of the trace inspection department to check, a group of rooms are some shelves, on which there are all kinds of cosmetics, The second group of rooms has a bedroom, and there is a separate space to put some daily necessities, the host introduced this is a spare bedroom for the guests, and the third group is the living room, the living room has a lot of sofas, the sofa surrounds the coffee table, and there is a washing machine, water dispenser, TV cabinet, several fans, the deceased fell on the floor next to the sofa, and there was no blood on the ground.

There is also an LCD TV on the TV cabinet, the items on the coffee table on the sofa are also messed up, the deceased is wearing suspender jeans, a white short-sleeved shirt, the deceased's face is facing the ground, his eyes are open to the ground, his feet are lying on the floor, the four groups of rooms are the dining room kitchen, the dining table is placed with unfinished leftovers, the kitchen is in front of the dining room, the five groups of rooms are the bedroom and the wardrobe, all the cabinet doors in the bedroom are open, obviously they have been turned over, and the south side of the corridor is a bathroom in the five groups of rooms, There are also traces of being turned inside, the approximate scene is like this, the deceased is Zhou Ling's, this is now waiting for Zhou Ling to come to the scene, the deceased has no external injuries, there are no traces from the surface, the ace focused his attention on the neck of the corpse, the deceased was strangled to death, this is a very obvious mark.

Ace looked at the eyes of the deceased with hemostats, the deceased's eye sockets were bloody, which is also a characteristic of ventricular breath, and the deceased's nails are very long, it is now a hot weather, people are wearing relatively little, if the deceased is strangled to death, then he must have resisted before his death, as long as he resists, there must be an instinctive reaction to scratch, so that it is possible to leave the suspect's human tissue cells in the cracks of the deceased's nails, and there are cells that can find out the suspect's DNA through testing, so that the suspect can be basically locked, The deceased's nails were painted with a lot of color, but a little mark could be seen from the thumb, and Ace used nail clippers to cut off the deceased's nails.

Under the leadership of Jin Shan, the trace inspection department checked that the entrance door of the second group had traces of being pried, and no fingerprints were found on it, and the entire room was turned into a mess, and no one was spared, and the wardrobe was turned over.

The locks of several drawers of the desk in the bedroom were all picked, and the things inside were also turned over in a mess, and the corpse was objectively dead from a room death, and from the point of view of opening his eyes, he was not blinded by death, and it was determined that he was killed, and now a clue was locked, that is, the deceased made up beauty, according to the neighbor next door who opened her store, the deceased suddenly came home and said that she forgot to bring her wallet, put it at home, and went home to get it, and the time of coming back was around one o'clock in the afternoon, and the deceased's wallet was not found at the scene, so it can be determined that the murderer was a burglary.

Ace analyzed. "Judging from the scene, there are several positions that we can prove that this is a burglary, from the door that was pried, it can be seen that the deceased's home was robbed, the deceased opened a shop outside, logically speaking, the deceased was looking at the store outside, and suddenly came back and happened to bump into the thief, which caused the murder, if the murderer caused him to kill for other reasons, then his target was the deceased's shop, not at home, because the deceased was not at home at all, and her home was completely just a coincidence, as for the food on the dinner table, the deceased's husband also saidIt was eaten for breakfast, and it was put there because I was in a hurry and didn't have time to clean it up. ”

Jin Shan analyzed. "Yes, it's a burglary, and it's an expert, the locks in the second set of rooms are silver-gray, the big locks and small locks are used, but the thief still gets open, the office drawers in the five bedrooms are also picked, the family calculates his lost finances, the deceased's mobile phone, the deceased's belongings, this is the deceased's finances, and the other is the situation at home, the stolen things have rings, necklaces, more than 6,000 yuan in cash, several antiques in the living room have also been stolen, more hateful things, the computer host in the living room, Computer monitors, mice, mouse pads, vases, and even food in the TV cabinet were stolen, and the total losses are still being calculated, because cosmetics in a group of rooms were also stolen, because the price could not be calculated because it was not known. ”

Ace analyzed. "We locked it as a burglary, we first had to figure out how the murderer got in, the whole building, the murderer could get in was the staircase, which is the only intersection, but there are two stairs in this building, no matter where it comes from, the suspect can come up, but there is no monitor at the staircase, only there is one in the stairwell, because there is a garage there, and the route of the monitor did not capture the suspect's route at all, so we can't find any details from this clue."
