The caretaker of a missing 4-year-old girl, who is believed dead, appeared to post photos and inspirational messages to her Instagram account after the girl's disappearance.

Athena Brownfield was initially reported missing on Jan. 10 after a postal carrier found her 5-year-old sister wandering around alone in Cyril, Oklahoma, around 2 p.m. Investigators believe Athena died while under the watch of her caretakers, Ivon and Alysia Adams, on Dec. 25, 2022.

Between Christmas and Alysia's arrest on Jan. 12, she posted multiple photos of herself and inspirational quotes to her Instagram account — despite confessing to police that Ivon beat the toddler to death on Dec. 25, according to an affidavit.

"When you start to love yourself everything else will fall into place," Alysia apparently wrote in the caption of a Jan. 3 Instagram post, along with a selfie.

Athena and her older sister called Alysia "Mom" and "Aly," according to the affidavit. They called Ivon "Dad" and "Uncle Ivon," the court filing states. Their biological mother, Jasmin Brownfield, left the girls in the Adams' care approximately one to two years prior to Athena's disappearance. The Adams did not take the girls to the doctor or enroll Athena in school, according to the affidavit.

"Alysia confessed that on Dec. 25, 2022, around midnight that night, Ivon beat [Athena] and held her by her arms, [Athena] was not moving and her eyes were barely open," Oklahoma State Bureau of Investigation (OSBI) Special Agent Brenna Alvarez wrote in a probable cause affidavit filed in Caddo County. "He then laid her on the ground and punched her chest at least more three times after that. [Athena] never moved after that."

The alleged abuse occurred at the Adams' home at 225 West Nebraska Avenue in Cyril, Oklahoma.

Ivon left the residence with Athena afterward and later told Alysia that he buried her near the fence line of their old property in Rush Springs, Oklahoma, according to Alvarez.

The Oklahoma State Bureau of Investigation (OSBI) announced on Jan. 17 that they had "recovered the remains of a child in rural Grady County outside of Rush Springs," though they could not confirm the remains were Brownfield's. Authorities are awaiting official autopsy results.
