An Oklahoma City grandmother has pleaded guilty to abusing her 7-year-old granddaughter in numerous ways, including terrorizing her by dressing as a witch.

On Thursday, 51-year-old Geneva Robinson admitted in court that she engaged in several felony counts of abuse on the girl.

These included pinching her with pliers, fracturing her pubic bone with a kick, cutting off her hair while she slept and forcing her to sleep outside with the dogs.

A 6-year-old child was also mentioned in the court affidavit, according to local station KFOR-TV. There were two other children in the family, but they were not mentioned in the court case.

Robinson had custody of the four kids for about a year after the children’s parents split up, according to The Oklahoman newspaper.

Robinson was arrested in October 2014 after she took the child to a hospital claiming she could not control the girl anymore.

Police were called because the girl looked malnourished and had burns and bruises all over her body, according to KFOR.

The victim’s ankles had cuts that were infected and her wrists “had the appearance of possibly being bound,” according to the police report.

Prosecutors said that Robinson engaged in these acts of abuse while dressed as a witch named Nelda, The Oklahoman reported.

Her 31-year-old boyfriend, Joshua Granger, reportedly would wear a demon costume and call himself Coogro.

Granger pleaded guilty to one count for assisting and “causing mental injury” to the girl, according to The Associated Press.

According to a court document obtained by The Oklahoman, the victim told a counselor that Nelda “goes into” her grandmother and makes her “do mean things,” and she said “Nelda eats bad kids.”

Robinson told the court Thursday that she is being treated for bipolar disorder and schizophrenia while in jail and that she was treated for mental illness in the 1970s in Texas.

Both Robinson and Granger will be sentenced March 28.
