Australian police have called off the search for a four-year-old child who has been disappeared in the outback for approximately several weeks, after additional attempts proved unsuccessful to locate any evidence of the boy.
Gus Lamont was spotted playing outside his home on a secluded farmland near Yunta, about 300km from Adelaide, on September 27th.
His grandparent left him alone for about thirty minutes before looking for him, only to discover the youngster gone, prompting one of the biggest land and air missions in the region's records.
Police - who do not think there was criminal activity - say they will persist looking into, but that the case has become a "search for recovery".
Last week, officials for a short time scaled back the search, only to recommence it on recently alongside eighty defense personnel.
"Commissioner Grant Stevens said authorities were looking a wider region based on updated analyses from medical and search experts, rather than any recent developments."
On Friday, police confirmed that the recent operation had not found any evidence of the child.
"The fact that the child is a little boy, the terrain is very rugged, harsh and experiencing unpredictable weather conditions has made the mission demanding and more challenging for those engaged," officials said in a announcement.
About 470 sq km - an zone about two times the dimensions of Edinburgh - has now been scanned, and a twelve-member team set up recently is anticipated to persist examining. Authorities have not discounted additional searches of the location in the future.
The child, who has been portrayed as an curious but quiet boy, was last seen wearing a gray cap, light-colored long pants, boots and a azure long-sleeve shirt showing a yellow cartoon figure.
The situation has generated significant interest throughout the country, with images of the blond, curly-haired youngster displayed in local media and conjecture spreading widely digitally.
It caused police to request that individuals discontinue calling them with their "speculations", and request for them to access updates from trustworthy channels.
Police recently said the child's relatives continue to be "stoic" despite the tragic conditions.
"One can understand just how they are coping... without having answers as to precisely where the boy is and what's occurred to him. This would be devastating for every families," Commissioner authorities said.
Via a family representative, the relatives household has before said they are "heartbroken" by Gus's vanishing.
"This represents a trauma to our household and friends, and we are struggling to understand what has transpired," the spokesperson said.
"Gus's absence is felt in each family member, and we yearn for him exceeding expressions can describe."
