GRANGEVILLE, Idaho (AP) — Northern Idaho authorities are investigating after all-terrain vehicle riders found a package containing a large sum of money on private land.

The Idaho County Sheriff's Office in a news release Tuesday says the ATV riders found the money Jan. 25 on property owned by Salmon Canyon Ranch LLC and alerted a person associated with the ranch.

Authorities say the ranch has disavowed any knowledge of the money and it was turned over to the sheriff's office.

Authorities say the packaging containing the money has been sent to the Idaho State Police Forensic Services for analysis.

Police have not revealed how much money is involved.

Police say one person has come forward to claim the money and that person's claims are being evaluated.
