FREMONT, Neb. (AP) — Police say a 7-year-old girl who died in Fremont had been face down in a beanbag chair in her elementary school classroom for about five minutes before she was found.

Kira Hales was found unresponsive Dec. 8, in her special education classroom at Milliken Park Elementary. She was taken to an Omaha hospital and pronounced dead on Dec. 10.

Fremont police detective Brandon Lorenson says an autopsy has been conducted, but more tests need to be done to determine Kira’s cause of death.

Kira’s father, Jerrad Hales, says his daughter, who had a genetic disorder, used a wheelchair but frequently spent time in a beanbag chair at school.

Freemont Public Schools superintendent Mark Shepard and principal Susan Farkas referred questions about Kira’s death to police, citing the ongoing investigation.
