Jennifer Budrawich, 22, was found by Dawson County authorities between 3 and 3:30 p.m. Sunday, Sheriff's Lt. Tony Wooten said.
Wooten said Budrawich was traveling with her husband Paul, 35, to visit family in north Georgia's Pickens County when she made the 911 call at 9:20 a.m. Saturday.
She was pleading for her life, Wooten said.
The 911 call helped investigators find the body, Wooten said.
She asked Why did you bring me down to the river, Wooten said.
The Budrawichs 1980s model Pontiac Firebird, was found about 11 p.m. Saturday in the parking lot of a supermarket in Pickens County, Wooten said.
The shopping center video led investigators to arrest two Dawsonville men in the case.
In custody are Jesse James Kilgore, 40, charged with Jennifer Budrawichs murder and Benjamin Kelly Mullinax, 27. Mullinax will possibly be charged with tampering with evidence in the disappearance of Paul Budrawich.
Both are family members of the victim.
Wooten said authorities would continue their search for Paul Budrawich this morning. He is considered in extreme danger, police said.
