Authorities are continuing their search for 18-year-old Celina Roye in the Northern Utah mountains, however they are doing so on a smaller scale than when the search started last week.”After conducting an investigation we believe at this time she is in the Cache National Forest by her own free will and choice,” a statement released Monday by the Cache County Sheriff’s Office reads. “We do not at this time have any evidence that she has been hurt or is in harm’s way.”Sheriff’s officials say Roye, who is from the Las Vegas area, is not lost and there’s a credible witness that has placed her at the Tony Grove campground on Thursday eating a plate of food. “We have continued the search at this time, but at a lower level than it was over the weekend,” said Cache County Sheriff’s Lt. Matt Bilodeau. “We are still asking the public’s help in locating her so that her family and friends can be assured that it’s what she wants to do and that is where she wants to be.”Bilodeau said Tuesday evening that he had nine searchers in the canyon at that time and earlier had four-wheelers and horses out looking. The search had to be scaled back, however.”We just can’t sustain 40 volunteer searchers for days on end,” Bilodeau wrote in an e-mail to KVNU. “She has been seen in the Tony Grove area getting food from campers there.”Anyone with information or questions can contact Bilodeau at 881-0228.
