CUSHING, Okla.--More details about a deadly sky diving trip over the weekend are emerging after Sheralynn Neff’s body was found miles away from her parachute Monday.

Now investigators are working to find out what went wrong.

Several agencies responded to the scene including crews from Payne County which is where the initial 911 call came in for help.

Lincoln County first responders were radioed for assistance after the 26 year old went missing during a skydiving trip.

The plane took off from the Cushing airport Sunday afternoon with a group from the Oklahoma Skydiving Center.

Neff’s body was eventually found a half mile away from the drop site.

NewsChannel 4 reached out to the Oklahoma Skydiving Center, and they tell us "We are doing everything we can cooperate with the investigation."

Right now the FAA is investigating what happened, but NewsChannel 4 has learned there are a few ways someone can fall out of a skydiving harness.

Skydiving experts tell us someone can slip through the bottom when leg straps are not tight enough or through the top if the harness is too big and a person slips through the shoulder straps or if a person unfastens the harness themselves.

The key, experts say, is the equipment must be the right size and fitted properly.

On Wednesday, the Oklahoma State Medical Examiner's Office determined that Neff's cause of death was multiple blunt force trauma.

Her manner of death is pending.
