Nicole Waller's sister, Carmen Keibler, tells NBC Montana she hasn't heard any updates since we last spoke with her on Friday.
Cami Ewalt, one of Waller's longtime friends, created a "Find Nicole Waller" Facebook page Saturday as a way to get Nicole's face and information out to as many people as possible. It's gained over 1,000 likes since then, and Ewalt said it's a blessing to have so many people reach out with their support.
"She is very tough, very strong. Very strong willed," said Ewalt of Nicole. "She went missing during the day. Somebody had to have seen something on Highway 2. It's a heavily traveled road for that oil crew. Her family wants her home."
Calls to Roosevelt and Richland Sheriff's Offices, as well as the Fort Peck Indian Reservation went unanswered. The FBI is not commenting on the investigation at this time. If you have any information on Nicole Waller, please contact local law enforcement.
