CUSHING, Okla. (AP) — Investigators are trying to determine how a Kansas skydiver was separated from her parachute harness during a jump in Oklahoma.

The body of 26-year-old Sheralynn Neff of North Newton was found Monday by authorities south of an airport near Cushing, Oklahoma.

Neff was reported missing on Sunday after she made a jump with the Oklahoma Skydiving Center.

Cushing police Chief Tully Folden says Neff’s parachute harness was found in a tree about 5 miles away.

The Oklahoman reports the Federal Aviation Association is assisting with the investigation. FAA spokesman Lynn Lunsford has said the agency’s main focus is determining whether the parachute was packed properly and if the harness was in good shape.

Neff graduated from Hesston College in 2011.

She was a high-achieving student who was involved with many different areas of campus life, according to a media release. She earned an associate of arts degree in Bible and Ministry with Dean’s List honors, served as a ministry assistant during her second year and participated in both choir and concert band.
