Authorities in La Paz County announced the discovery of Nenigar's body on Friday night in a remote area south of Cibola, Arizona.
"We urge everyone to show respect for the family during this difficult time and refrain from spreading unfounded rumors," stated the sheriff's office.
According to reports, the woman's unclothed body was found beneath a tree approximately 1 ½ miles away from her deserted vehicle.
County Sheriff William Ponce revealed to CBS affiliate station KPHO that Nenigar was identified by a rose tattoo on her right hand.
Given that her clothing was discovered near her body, investigators speculate that she might have succumbed to the elements while attempting to cool off, as per Ponce's statements to KPHO-TV.
The sheriff's office confirmed on Saturday that the investigation is ongoing, with an impending autopsy set to determine the cause of Nenigar's death.
Nenigar was last seen alive.
Authorities said Nenigar lived near Blythe but frequently drove to La Paz County where her other family members live.
KPHO previously reported, "I'm like kind of in a valley," Nenigar said at one point. "Yeah there's just a lot of mountains … But I climbed to like a high mountain and I'm wearing pink," Nenigar said on the call.
"OK, so you're on Highway 78, you think? And what would be the nearest cross streets?" the dispatcher asked.
"Um, I'm not sure. I see a field," she replied.
"I'm trying to get a location on you but I'm not getting one," the dispatcher said.
"She gave them her coordinates, California, and I don't know why they didn't transfer her to dispatch in Arizona," her sister Marissa Nenigar said after the 911 call was released. "She gave them her exact location and someone could have gone and got her. They could have found her."
