Australian tourist Sally Grace Contarino, 26, went missing in Las Vegas on June 20 after messaging a male friend on Facebook Messenger that she was going to Lone Mountain for a hike. The Las Vegas Metropolitan Police Department has since classified her as an endangered missing adult who may be experiencing severe emotional distress and be in need of urgent assistance.
The available evidence about her last known whereabouts consists of only a handful of confirmed details. This leaves far more questions than answers.
