BYNG, OK - An affidavit obtained by KXII states that during 20-year-old Riley Walker's interview with Ponotoc County Sheriff John Christian Monday, he admitted to striking and squeezing his one-year-old daughter Jalissa.
Walker was then taken into custody and charged with child abuse.
But once the medical examiner ruled her death due to blunt force trauma to the head, the document states Walker admitted he had not told investigators everything.
"Multiple contusions also all over the baby's body, we knew that but along with the skull fracture and the blunt trauma to the head I think has made a difference in the case," Sheriff Christian said.
In the affidavit, Walker gave a more detailed account of the events leading up to the little girl's death.
He said she had been sick and vomiting and continued to cry.
Walker said he squeezed her until she couldn't breathe and spanked her to be quiet.
He went on to say that he tripped and he fell on the toddler where she became unconscious.
Walker said in attempt to wake her up he shook Jalissa and struck her in the face.
He says he hid the dead toddler in her room until her mother, Kelsey Sankey, found her around midnight Monday and called the police.
District attorney Chris Ross says at this time, there is no evidence that the mother was involved in the death.
"Well the investigation always continues but based on what we have right now, he will the only person charged, based on what we have right now," Ross said.
The couple does have another two-year-old son who is currently in the care of the Departmetn of Human Services.
Jalissa Walker's funeral is set for Saturday Oct. 15 in Geary, Oklahoma.
Walker is expected back in court Oct. 19th and is being held without bond for first-degree-murder and could be looking at the death penalty.
"That's a possiblity, this time there certainly is that possiblity that the district attorney will go that route," Sheriff Christian said.
