The body of 21-year-old accident victim Tiffany Maupin was found about six miles downstream from where her car crashed into the river on May 17.
According to the sheriff's office, a resident found the body at around 8:42 a.m. No other details were immediately available.
Maupin was traveling north along Highway 95 on May 17 with 20-year-old Cayla Danenberg when the 2004 Nissan Maxima crashed into the Salmon River about six miles north of the town of Lucile.
Search and rescue failed to locate the submerged car because of bad weather.
Maupin's body has been taken to Trenary's Funeral Home in Kooskia. Both women were graduates of Columbia High School in Nampa.
