Authorities are searching for Sally Grace Contarino, a 26-year-old woman from Melbourne, Australia, who goes missing after sending a message indicating she planned to hike near Las Vegas. Both reports say Contarino sent a communication on June 20 that she was going for a hike near the area, and she has not been seen or heard from since then. One account describes her as telling a male friend on Facebook that she was going to Lone Mountain for a hike. The other report similarly states she sent a message about going for a hike near Las Vegas and that the disappearance has remained unresolved for roughly three weeks. The search is ongoing, and investigators are working to locate her and determine what happened after her message. Authorities have not reported confirmed details about any specific incident or cause, and the available coverage focuses on the last known contact and the area where she said she would be hiking.
