A South Carolina mother whose daughter is missing from the Symbiosis event is in contact with the Crook County Sheriff's Office.
Sheriff John Gautney said the Christine Syms case is still an active investigation.
"We are following all possible leads or other locations she may have gone to," he said. "We have not ruled anything out at this point."
According to the Oregon Missing Report website, 32-year-old Syms has been missing since Monday, Aug. 21. She was last seen at the Big Summit Prairie Symbiosis festival. According to her friends, she drifted on into the crowd and has not been seen since.
She is described as having brown hair and brown eyes and is 6-feet tall and 125 pounds. She has a tattoo on her left wrist and one on her neck.
Gautney said Syms is listed in the nationwide computer system as a missing person. Her information and photo have been released on social media.
"We have contacted other law enforcement agencies in Nevada as a location she may have gone," he said.
Syms' case is not the first missing person case the local authorities have dealt with recently.
Gautney said they have had 78 missing person-related calls to date. Of those 78 calls, they took four actual reports that needed further investigation. The Syms case is still an active investigation.
They were able to clear one other case Tuesday night, Aug. 29, when a person was located still working at Big Summit Prairie.
"Mostly all issues with missing person calls were due to no cell coverage/internet," Gautney pointed out. "Issues that make investigating these cases difficult were that there was no cell service in the area or internet, the vast number of people on site of the event, the fact that many of the people had no alternate plan to communicate with family members, and that the event went longer than they had reported that they would be home."
The other issue, he added, is that many have left to go to other events around the country without communicating this to family.
"I don't have anything more to release to the public at this time as everything we have has been released," Gautney concluded.
