There were other reasons for depression too. He was a gambler and had taken a lot of money as loan from his friends. Some of them were pressing him to return his amount, and some were even threatening him with dire consequences, if he did not return the amount soon. The main among these was a person known as Mahto. He was seen entering Ramlal's house yesterday evening.
Nobody knows what happened after that.
Today morning when the maid came to Ramlal's house and knocked at his door, nobody opened the door. She got suspicious and called the neighbors. Oh, I see. So definitely Mahto must have killed Ramlal. But surely he didn't die a natural death.
