Contacted, father of the deceased, Sanjo Fakeye, demanded justice.
Mr Fakeye explained that "when Janet arrived from school on Wednesday, after completing her assignment, she told me she wanted to buy detergent in our neighbour's house to wash her socks.
"I gave her money to buy the detergent. After a long time, I didn't see her return from the place she had gone to buy the detergent.
"So, I went to check on her, I was told she had been attended to and had left the place, I became troubled and I went to her friend's place to ask for her but she wasn't there.
"I later went to report at the police station around 8:00 pm after we had searched and could not find her. As we were coming back from the police station, I received a call from the community that they had found the dead body of my daughter."
Mr Fakeye said he found his daughter in an uncompleted house with the soap she had gone to buy with blood stains.
