Investigators said the man accused of killing his five-year-old daughter this week, said he did it because he believed the girl was controlled by witchcraft.
Adam Mason was in court Friday, now charged with Murder in Indian Country.
In Adam Mason's arrest affidavit filed Friday in federal court, Mason told investigators he believed his daughter was "controlled by witchcraft," and punched her in the face.
Mason told investigators he drowned the little girl in a bathtub, then put her in a creek bed. Mason also told investigators he set the five-year-old on fire.
The court document said the mother last talked with her daughter Tuesday night, and became concerned when she said Mason refused to let her speak to her daughter the next day.
Law enforcement went by to check on her, only to find it was too late. In a statement, U.S. Attorney Trent Shores calls the case "heartbreaking."
Shores also said, "Now, it is time for our criminal justice system to go to work. The FBI, ATF, Creek County Sheriff's Office, and Muscogee (Creek) Lighthorse will continue their joint investigation."
While investigators are not confirming the girl's name, the assistant principal and counselor at her school in Bristow said Thursday the young girl was "bubbly," and "ready to learn."
She would have started kindergarten on Monday.
"She was full of life. And had a lot of life ahead of her,” Edison Elementary Counselor Cindy Wayland said.
Mason's attorney said he was just appointed Friday to represent the suspect and has no comment on the case right now.
