The devastated family of toddler who vanished without a trace from a rural property are convinced he was abducted as police desperately search for the missing three-year-old, seizing a white ute and CCTV from a service station.
Anthony 'AJ' Elfalak, three, was with his family as they were getting ready for lunch on Friday morning at their 256ha rural property in Putty, about 150km northwest of Sydney in the Upper Hunter.
AJ, who has autism and is non-verbal, was last seen playing on the porch - with his mother saying he was out of her sight for just a matter of seconds.
His mother Kelly insisted AJ is 'not a wanderer' and 'never leaves her side', with his father Anthony adding 'a kid doesn't just up and disappear'.
In a worrying development on Sunday, with police still scouring the area for clues, a white ute from a nearby property was taken by police as they searched an abandoned shack.
Police also seized CCTV footage from a Colo Heights service station, which is a 40 minute drive south from Putty in the direction of Sydney, declaring it a 'site of interest'.

'I'm his universe. He holds my hand, all day and all night we are together,' the boy's mother told The Australian.
She and the boy's father joined the large search party - including police divers, the riot squad, trail bikes, drones and mounted officers - who were searching for the toddler over the weekend.
His family even brought in a private helicopter to scour the area as police launched Strikeforce Jaylang to investigate the circumstances of AJ's disappearance.
'He's been taken. If he was around here, I would have found him by now,' Ms Elfalak said.
'I have searched the property... I'm still driving around and I cannot find him. If he was here, he'd be close to the property.'
Despite a search party being set up 10 minutes after AJ went missing, with four vehicles soon covering a large radius around the farm, he was nowhere to be found.
Ms Elfalak also said she noticed a suspicious white ute driving away from her house in the minutes after AJ vanished.

'I saw it, it was driving really slowly, I thought it was my neighbour's,' Ms Elfalak told The Daily Telegraph.
'He's not a wanderer... he never leaves my side.'
She was in the kitchen as AJ played on the porch, while his father was nearby in the yard fixing the chain on his quad bike.
AJ was dressed in a grey top and pants with sneakers and is described as being of Mediterranean or Middle Eastern appearance, with short brown hair.
Officers on Sunday were seen talking to one of AJ's older brothers - he has three brothers Michael, Patrick and Alexander - in a paddock near the house, with one of the young boys taking
