It is a villa built in a sparsely populated suburban area. The villa is in European style, and outside the villa, a Cadillac SUV is parked. It seems that the owner of this villa is also considered a wealthy man.

But in this villa, there was a tragedy, the old couple living in the villa were brutally killed, and the property in the villa was looted.

Lao Lu stood in front of the gate of the villa, stopped to look around, and said to me with some puzzlement: "Ouyang, you see that this is not a villa area, and the surrounding houses are also two-story buildings in the countryside, why is such a luxurious villa built here?" ”

I said: "I can understand that the land where this villa is located used to be the land of the villa owner's rural property, but the family may have made a fortune for some reason, so they spent a lot of money to build such a big villa on the original land." ”

Lao Lu nodded and said, "Well, it's very likely." In the subsequent investigation, my conjecture was confirmed, the villa was built for him by the son of the deceased, and the son of the deceased opened several electronics factories in the coastal city, so he built such a luxurious villa in his hometown.

Perhaps it was because of the luxury of this villa that it caused trouble, and it was a fatal disaster.

The weather is still hot in the summer, and the crazy chirping on the branches of the trees sounds even more hot and boring in this hot weather.

Outside the cordon, the villagers who stopped to watch were unwilling to give up their curiosity in the scorching sun. These people are people who have worked hard in the field all their lives, maybe they don't care about such a scorching sun at all.

Before entering the crime scene, I first circled around the villa because I wanted to know how the killer got into the scene.

The villa is surrounded by maroon red walls with delicate wooden fences on top of them. This wooden fence is whitewashed and can easily leave footprints if you climb over it.

I checked all the fences and found no footprints on the white fences, so I concluded that the killer did not climb over the fence wall to enter the house. Of course, I didn't just tell that there were no footprints on the fence wall, but I didn't find any footprints on the periphery and inside of the fence wall.

Didn't you climb in, did you pry the door in? This idea was quickly shattered, as the metal gate, which was connected to the fence wall, showed no signs of the lock being picked.

Entering the iron gate of the fence wall, there is a wide open space, and the floor of the open space is watered with high-quality cement. At the edge of the clearing, there is a flower bed, and the flowers and plants inside are still lush in this hot summer day.

On both sides of the gate of the villa, there are two huge iron trees, and the pots used for the iron trees are like two huge water tanks.

I checked the main door of the villa, and there were still no signs of prying on the gate, and there were no signs of prying or climbing on the surrounding windows. So the murderer entered the villa peacefully, could it be that the murderer had the key?

In the living room of the villa, the man collapsed in a pool of blood, and the cause of death was a stab in the neck and a stab in the heart.

Judging from the murderer's use of the knife, it was very powerful and very fast, and it was obvious that this was the work of a man with amazing arm strength.

The man was in his 60s, lying flat on the ground, his eyes protruding and showing a frightened look.

I looked at the time, it was 10:27 a.m., and judging by the temperature and the corpse spots, the deceased should have been killed four hours earlier. That is, the deceased died around 6 a.m.

The deceased died next to the shoe closet, and he was wearing a white short-sleeved shorts tracksuit, sneakers on his feet, and fresh dust on the soles. This indicates that the deceased must have been killed when he had just returned home from morning exercise and was about to change his shoes next to the shoe closet.

Through the luxurious handrail staircase, I reached the second floor, where several on-site investigators were taking pictures for evidence.

In the master bedroom on the second floor, a gray-haired woman died next to the safe.

The female deceased, as the male deceased, was fatally stabbed in the throat and heart with a knife.

I examined the female deceased, who was about 55 years old, wearing pale pink pajamas and no shoes on her feet. But on the other side of the bed, there was a pair of red slippers, which were neatly arranged.

It can be seen that the woman was broken into the bedroom before she died, she was still sleeping, and was awakened by the murderer in her sleep, and then was murdered after being forced by the murderer to open the safe.

Based on the corpse spots and corpse temperature, it is inferred that the woman's time of death was also around 6 a.m., a little earlier than the man's death.

I checked the other rooms of the villa and found that there were no signs of turning inside, which may indicate that the murderer knew the family very well, and his purpose was to come to the safe.

The safe usually contains cash and some valuables. I checked the safe, which is two layers, and the upper layer has some bills, real estate deeds, etc., there are traces of turning, but they have not been removed.

The floor below was empty, and I guess there should be cash here. After understanding the deceased's son, it was learned that there was indeed 100,000 yuan in cash in the safe.

There was a high-end mobile phone on the dresser in the bedroom, and some gold and silver jewelry was on the countertop, but the killer did not take it.

Lao Lu looked at the dresser and said, "If it was a robbery and murder, then why didn't the murderer take these valuable items?" Could it be that there was another motive for this killing, the robbery of the safe just to hide people's eyes? ”

I said, "I can't deny your conjecture, but I have a different opinion. ”

Lao Lu looked at me and said, "Let's hear it." ”

I said, "Maybe the killer didn't see the valuables, or maybe the killer saw the valuables but didn't take them." Because these things are not cash, you need to find a channel to sell the stolen goods after being stolen. Assuming that the murderer is not a habitual offender, he does not have a good way to sell the stolen goods, and he is worried about revealing his identity in the process of selling the stolen goods. So he didn't take these valuables away. ”

Lao Lu nodded and said, "There is some truth, but the murderer's motives for killing are diverse, and it is still necessary to take into account." ”

I said: "This is inevitable, because judging from the situation when the murderer entered the scene to commit the crime, the murderer is very familiar with the living habits of the family and the location of the safe. It cannot be ruled out that an acquaintance committed the crime. The murderer chose to commit the crime at 6 a.m., because he knew that the man had a habit of morning exercise during this time period. And the murderer also knew that the family was only such an old couple at home, and more importantly, the murderer could quickly determine the location of the safe. At the same time, there is one of the biggest suspicions, that is, when the murderer entered this villa, he did not pry any doors and windows, which means that he has the key to this villa. So where did he get the key? ”

Lao Lu shook his head, frowning and pondering.

I walked out of the villa and walked towards the crowd of people who stopped to watch, so I asked a man who was a little bald and about 40 years old, "Big brother, do you know who the owner of this house has ever had a conflict with?" ”

The man said, "Conflict? No way, Lao Li and his family are good people in our village, Lao Li used to be the village party secretary, is an old party member, and later in order to get rich, he took his son to the sea to do business, opened several factories, and many young people in the village are working in their factories. He can be regarded as the benefactor of our village who took the lead in getting rich, who would have a conflict with him? ”

I frowned at the sun and asked, "Then has he been in close contact with any acquaintances recently, relatives and friends?" ”

The man said: "Who knows, the closest person to their family should be their nanny." This nanny was specially invited by Xiao Li to take care of the old couple. You see, the room on the side of the villa is the nanny's room. ”

It dawned on me and I said, "Oh, thank you, thank you." ”

Just now when I was looking at the villa, I noticed this cottage outside the villa. At the time, I thought it was a utility room, but I didn't expect it to be a babysitter's room.

This room is outside the villa, the door is on the side of the villa, not inside the fence wall, it is a side room that is separate from the villa. And judging from the construction of the earthworks, this room is newer, apparently a side room that was re-added after the villa was built, presumably a room specially for nannies.

But I think it's very strange now. Because when we came to the scene of the case, no one who claimed to be a nanny came to explain the situation to us, and we did not see the appearance of this nanny. Could it be that the death of the old couple was caused by the nanny's self-theft?

This possibility is very large, there is a key to the villa, know the work and rest time of the old couple, know the location of the safe in the villa, which is all related to the nanny.

I also learned from the crowd around me that the nanny was a woman in her 30s. I judged that the means and strength of the murder came from a man, so could this murderer have something to do with the nanny?

In order to find out the real situation of this babysitter, it seems that this babysitter must be found first. Lao Lu contacted Xiao Li, who was hurrying home from other places, and got the contact number of the nanny.

Lao Lu dialed the phone, and the phone was connected, but no one answered. I was standing by the door of the nanny's hut when I heard a faint ringing of my cellphone. This bell is coming from the nanny's room, is the nanny still in the house?

Until the music was over, the babysitter did not answer the phone, and at the same time, the mobile phone ringing in the house also stopped.

I asked Lao Lu to call the nanny again, and the bell in the nanny's room rang again. But the nanny still didn't answer.

It can be ascertained that the babysitter's phone is inside the house. Obtaining this phone call may be the breakthrough in the case.

When the police opened the door to the nanny's house, everyone was stunned, and the nanny fell to the ground covered in blood, already dead for a long time. And her mobile phone is on her own small bed.
