A Melbourne woman who vanished in Las Vegas almost two weeks ago was unknowingly filmed by a social media pick-up artist just days before she disappeared, with the newly surfaced video now offering one of the last known public sightings of the missing tourist.Sally Grace Contarino, 26, has been missing since June 20 after failing to board her scheduled flight home to Australia, prompting an urgent search by Las Vegas Metropolitan Police.Authorities have declared Ms Contarino an “endangered missing adult” and said she may be experiencing “severe emotional distress” and could require medical assistance.The video, which has since gone viral, shows a young woman believed to be Ms Contarino standing outside a 7-Eleven on Boulder Highway in Las Vegas when she is approached by Instagram creator @epicDamianpov, who regularly uploads videos of himself approaching women in the city.Filmed using Meta smart glasses, the clip begins with the man walking towards the Australian tourist as she shelters from the afternoon sun while smoking a cigarette.“Sorry, I saw that you were very beautiful and I was wondering if I could get your number, by chance?” he asks.Smiling politely, Ms Contarino declines his advance.“I have a boyfriend,” she replies.“Oh, OK. Are you waiting for him, or…?” he asks.“No, I’m just going to have a cigarette and go inside,” she responds.The brief exchange ends moments later as the man returns to his car. He later uploaded the clip with the caption: “Trying to pick up a beautiful woman.”News.com.au has contacted the content creator for comment. It is not suggested he had any involvement in Ms Contarino’s disappearance.While the video was uploaded on June 28, social media page Real Vegas Locals, which has been spreading awareness about the case, said it obtained the original file from the creator and reviewed its metadata, which showed it was actually recorded on June 17 at 3.46pm local time.The embedded GPS data matched a 7-Eleven at 4880 Boulder Highway in Las Vegas, making it one of the last publicly known videos of Ms Contarino before she disappeared.Ms Contarino had been travelling solo through California and Nevada and was due to fly home to Melbourne on June 21.On June 19 she texted friends: “I’m about to hike up Lone Mountain then go home – I fly back tomorrow.”That evening CCTV captured her spending almost two hours at Timbers Bar & Grill, where staff later described her as calm, quiet and in good spirits before she left alone on foot.The Sun US reported restaurant manager Jocelyn Zeigler-Arthur said the neighbourhood surrounding the hostel where Ms Contarino was staying was “terrible”.“It is not great for a girl alone,” she said.Police said CCTV captured Ms Contarino returning to Bungalows Hostel during the early hours of June 20.According to her family, she told hostel staff she would return to collect her luggage, visited a nearby cafe where she ordered breakfast and a protein smoothie before boarding a bus to Mount Charleston, a popular hiking destination northwest of Las Vegas.Detectives believe she got off the bus and entered the national park, where she is understood to have planned a hike. Police say she was known to enjoy hiking and had previously visited the area.Investigators have since recovered Ms Contarino’s luggage, deployed search dogs using her clothing, conducted extensive grid searches and confirmed a Greyhound bus ticket she purchased to Los Angeles was never scanned.Police also said there is no CCTV showing she boarded the bus.Ms Contarino’s sister Lauren has been raising awareness online, describing her sibling as an experienced traveller who loved the American desert landscape, while also revealing she had experienced mental health struggles.Las Vegas Metropolitan Police are urging anyone who may have seen Ms Contarino in the Las Vegas or Mount Charleston areas before she disappeared to come forward.She is described as having a slim build, brown hair and brown eyes. She was last seen wearing a grey or blue sweatshirt, denim shorts, black-and-white shoes and carrying a bag.Anyone with information is urged to contact the Las Vegas Police Department at MissingPersons@lvmpd.com.Read related topics:Melbourne
