A jury found Michael Huckabee guilty of Homicide By Child Abuse, Criminal Sexual Conduct, Inflicting Great Bodily Harm On A Child and Unlawful Conduct Toward A Child on Friday afternoon.
The jury deliberated for about 45 minutes before they reached their verdict.
Huckabee was on trial this week for the death of Edna Trinity Hunt, 3.
Hunt died on October 6, 2011.
Judge Michael Baxley sentenced Huckabee to two life sentence
Marlboro County Coroner Tim Brown said autopsy results revealed Hunt died from unusual complications of a urinary tract infection, which was left untreated, and multiple inflicted traumas.
The girl's mother, Atelia Hunt, pleaded guilty to Homicide By Child Abuse and was sentenced to 20 years in prison.
Hunt lived with Huckabee at the time of her daughter's death.
Huckabee took the stand in his own defense Thursday afternoon.
During opening statements, Fourth Circuit Assistant Solicitor Mary T. Johnson-Lee says Hunt and Huckabee met online and eventually moved in together.
Lee says the child started being abused a short time after.
Edna Trinity Hunt had cigarette burns to her private areas and bruises on her body, Lee said.
She added the girl's head had been shaved and her teeth yanked out.
The little girl had also been raped, according to Lee.
The first witness to testify was a registered nurse at Marlboro Park Hospital in Bennettsville.
Linda Hooper says she was working in the emergency department when the child's mother brought her in asking for help.
"She said something to the effect, 'Help me. My baby's not breathing,'" said Hooper.
Hooper cried as she explained the child's injuries to jurors.
"I've never seen anything like it and I hope I never do again," Hooper explained.
