He would always come to my house to greet me, or would even ask me how I am whenever we met on the street. I don't believe what I have heard."I wonder what possessed him to turn on his family. I was expecting a lot from him. He was like my own son. I loved him because of his well-mannered behaviour," the neighbour said.She said she was woken by screams coming from the house.'He must be punished'"I heard screams and I thought it was drunk people who were fighting on the street. Later, I was again awoken by neighbours screaming for help. I went out and was told what had happened. I almost collapsed because of shock. I still don't believe that the boy I loved and respected could have done such an ugly thing," said the woman.Another neighbour said she went outside to see what had happened when she was woken by screams."I saw the 16-year-old boy running out screaming for help. As a woman I was afraid to go and see what happened inside that house. I waited until I saw police arriving and that is when I learnt what had happened."If only I was a man with strength, I would have went into that house and assisted them. Unfortunately, as a woman, maybe he could have stabbed me too. I am speechless and don't know what to say. I hope he heals quickly and faces the law."He must be punished for what he did," she said.Police spokesperson Captain Teboho Lephoto said the man was under police guard in hospital after he allegedly attempted to kill himself.Lephoto said the suspect would face two charges of murder and two of attempted murder.
