Ivon Adams, one of the caretakers for 4-year-old Athena Brownfield when she disappeared, allegedly beat her to death and buried her near their old house, according to court documents in the case against him.On Tuesday, the Oklahoma State Bureau of Investigation announced it recovered the remains of a child and that they will be taken to a medical examiner’s office for positive identification.The affidavit for Adams’ arrest alleges that his wife, Alysia Adams, confessed to authorities in a January 12 interview that her husband beat Athena on Christmas night and “held her up by her arms.”Athena was “not moving and her eyes were barely open,” the affidavit alleged.In its Tuesday announcement, the state’s bureau of investigation said the child remains were recovered in rural Grady County, “outside of Rush Springs.”Ivon Adams, who was arrested Thursday in Arizona, faces one count of murder in the first degree and felony child neglect, according to online records for Caddo County, Oklahoma, District Court.According to an affidavit in her case, the children’s biological mother left the girls in the couple’s care roughly two years earlier, but the pair didn’t take them to the doctor for check-ups and didn’t enroll Athena’s older sister in school."
