Documents: 4-year-old Nahla Miller's father was trying to get custody before she died View Comments Nahla Miller's father was attempting to get custody of her before the 4-year-old died from injuries she sustained after she was allegedly beaten by her mother. Nathaniel Miller, Nahla's Father, filed for custody in January, saying that Nahla's mother Tianna Robinson had cut off all contact with him. In court documents, Miller said, "Tianna Robinson has stopped letting me see my daughter after I been there her whole life. I was even getting her half of the week every week. She has stopped talking to me and won't text any of my numbers back."
