The Ohio Bureau of Criminal Investigation worked through the weekend to test the remains confirmed as those of the 19-month-old girl. Results were confirmed Monday but police didn't make the revelation public until Tuesday because they needed to notify prosecutors and the child's family and prosecutors, WNWO-TV, Toledo, said.
Elaina's parents, Angela Steinfurth and Steven King, remain jailed on obstruction of justice charges. King's mother, Julie, told WNWO it was her son who led police to the child's remains in a cardboard box wrapped in a tarp in the rafters of a garage next to her east Toledo house. Steven King and Steinfurth were living at his mother's house when the child disappeared.
CBS News said King spent several hours at police headquarters Thursday, possibly negotiating a plea deal before telling police where the body was hidden.
Police had searched the garage and even looked in the rafters but failed to find the body three months ago when the child's disappearance was first reported.
It was unclear what additional charges might be brought against the two since their child's body was found.
King is scheduled to face trial on the obstruction charge Monday.
