WICHITA, Kan. (AP) – A coroner’s office wasn’t able to determine what killed a 2-year-old Wichita girl whose body was found in a field.

Medical examiner Timothy Gorrill says in an autopsy report that toxicology tests on Jhornee Bland were negative and the cause of her death will be listed as undetermined.

The girl was found dead in a field May 9, a day after her mother reported her missing.

Wichita police have said her body showed no signs of trauma. Investigators said they believe she died early Sunday, May 8.

A babysitter was caring for Jhornee in the days before her death. Police have said the babysitter put the girl’s body in the field and lied to her mother about Jhornee’s whereabouts. The babysitter was arrested but later released without charges.
