Police in eastern Oklahoma say a 44-year-old woman was killed after crashing to the ground while skydiving.

Heather Glasgow of Poteau died at a hospital after the fall Saturday afternoon, according to police in Sallisaw.

"An unknown issue arose during the skydive," according to a statement from Sallisaw police.

Witnesses told investigators that Glasgow’s parachute had opened, but she was spinning and did not recover before hitting the ground in Sallisaw, near the Arkansas state line and about 150 miles east of Oklahoma City, police said.

The Federal Aviation Administration is assisting in the investigation.

The FAA said in a statement that it is investigating the packing of the main and reserve parachutes while local authorities are in charge of other aspects of the investigation.
