Officials have announced that they will release further details as the investigation progresses.
The case of Gus’s disappearance is currently being treated as a major crime by South Australian law enforcement.
Authorities have reiterated several times that Gus’s parents are not under suspicion regarding his disappearance.
Earlier this year, police revealed that an individual closely connected to Gus’s family, but not one of his parents, was initially cooperating with detectives. However, this person later ceased cooperation and has now been classified as a suspect.
As part of the ongoing investigation, authorities have charged Gus’s 75-year-old grandparent, Josie Murray, with offenses related to firearms. They have clarified that these charges are not connected to the young boy’s disappearance.
Josie Murray and Gus’ other grandparent, Shannon Murray, released a statement through their lawyers, saying they were “absolutely devastated” by SA Police’s statement on February 6.
“We are absolutely devastated by the media release of SAPOL Major Crime. The family has cooperated fully with the investigation and want nothing more than to find Gus and reunite him with his mum and dad,” the statement read.
The lawyers also indicated they will not be making any further comments.
There is no suggestion that Josie or Shannon Murray is involved in the disappearance of Gus, and it is not unusual for anyone linked to an investigation to seek out legal advice.
Gus was last seen playing on a dirt mound at Oak Park Station around 5pm on September 27.
Following his disappearance, a full-scale ground and air search of the property and the surrounding area was launched.
No evidence of Gus has been uncovered despite extensive searches of the property, which Detective Superintendent Darren Fielke said has been the “largest and most intensive” missing person search ever undertaken by SA Police.
The most recent search was called off in March after police were unable to find any new evidence, despite heavy rainfall in the area.
The multi-agency search for the missing toddler has expanded more than 700 square kilometres with the assistance of 80 Australian Defence Force soldiers, drones, mounted officers and aircraft.
More than 160 South Australian police officers have also been deployed, and authorities have received more than 150 tips about the missing boy since February.
