Officials have located the body of missing Nevada 18-year-old Naomi Irion in a remote part of Churchill County, according to the Lyon County Sheriff’s Office.

Her body was discovered Tuesday in what deputies described as a remote gravesite. It was transported to the Washoe County Medical Examiner’s Office for an autopsy, officials said, where Irion’s identity was confirmed on Wednesday.

Deputies said a tip led to them to the remote area.

Irion was last seen alive on March 12. Deputies arrested Troy Driver, 41, last week, charging him with first-degree kidnapping.

On Monday, the FBI announced it was offering a reward for information leading to her discovery.
