There is a house exist at the end of this city which name is Niladry mansion. It is a big house but all of the family member of the house live in abroad. So instead of a big mansion it always remain empty. There was two caretaker for take care of this mansion. They used to clean it once / twice in every month. As their plan today is the day to clean that mansion and they are doing that but after sometime they noticed 4 dead body there. So they immediately informed it to police and police came there within 20 minutes.
After reaching this murder spot police started to ask manything from those care taker. Police asked them if they have noticed something suspicious. Then one caretaker said that one day ago he noticed that one light was on at midnight but he was afraid to see that and thought it might be some act of ghost and went to sleep immediately and in next morning he found the light was off . At first police started to find out the identity of those 4 young dead bodies and informed it to their family members. Police figured it out that four of them belonged to 4 rich family. And four of them were friends from their childhood. Police also gained the information that they were missing from last 2 days. And their family member made a complain in police station for it.
After see those dead bodies it was very clear that matter are tortured all of them badly seems like a psycho and don't have any kind of emotion. Police guessed that the murder was very curel . Police immediately send those dead bodies into hospital for postmortem. Police still found no clue about the murderer. They noticed that in the road there was CC camera. So they started watching the CCTV footage for investigation purpose. Watching the CCTV footage they didn't get any proof which is related to murder. They found 3 friend went there by their choice and they was alone and nobody was there to force them to go there.But they noticed that young man visited this road several times from last week where very few people pass by this road. It could be a normal thing but still police have to investigate it . The name of that young man was Alauddin who live nearby there.
Police started asked many information about him to other people. They figured it out that he is a very decent and respective young man. He belongs to a middle class family. He is very polite and he love his family member very much. In his family ,there he lived with his parents and his little sister. And they were leading a happy life. But 10 days ago his sister commited suicide and the reason is still unknown to everyone.
Police talked with Allauddin and his family also to know the reason behind the suicide but they said thet they didn't know the reason yet and they got emotional and started crying while saying about this. It's normal and police found no clue related to the murder of 4 young man. And the suicide of Allauddin's sister also looking like a mystery also.
After 2 days police found the postmortem report and there they got the fingerprint of the murderer in four young men's body. Police collected the fingerprint from Alauddin also because they can't take any risk in this case although they were petty sure that he is not a murderer. But the fingerprint matched and it was enough proof to say that Alauddin is the murderer of those 4 young man.
Police arrest Alauddin and start interrogation. At first Alauddin said that he was innocent but he understand that there is no way to say lie anymore. So Alauddin started to say the truth and he confessed his crime. He said that He captured one of them first and tortured him and forced him to call another friend there secretary. One by one he captured all of them like this.
Police asked him what is the reason for killing those four. Alauddin said that they are the reason because of what his sister commited suicide. Those 4 rich young man raped his sister when she was returning from her coaching. 4 of them captured a video of it and said that if she say anything about the incident to anybody,they would make viral this video in online. After 3 days they again started blackmailing my sister to intimate with them again otherwise they would release this video online. For this reason his sister decided to finish her own life. And he knew about it after see the message conversation of his younger sister although it was too late for him.
Instead of killing 4 people Alauddin don't feeling sorry for his act and he is laughing loudly saying that he gave the punishment for their crime and avenged his sister.
