Detectives have returned to the vacant block where human remains were found in Adelaide's northern suburbs.
A gardener made the gruesome discovery when clearing long grass on the vacant block at Salisbury South just before 2pm yesterday.
Police say the human remains found were so decomposed that forensic testing is underway to identify the age and sex of the deceased.
Today Major Crime officers and State Emergency Service volunteers searched the area for more information.
Detectives have used whipper snippers to clear long grass in the area.
They have also searched barrels located on the vacant block.
The area remains cordoned off to the public.
A business owner in the area, Kevin Boyle, said the road is predominantly used by industrial businesses.
"During the day it's really busy … but by five o'clock it's pretty quiet," he said.
"We do get a few hoons since no one's here, they like to come and burn out."
He said he was alerted to the discovery yesterday when the road was closed by authorities.
"We saw the road closure and the police out there with flashing lights," Mr Boyle said.
"We didn't have a clue what was going on.
"You don't really find someone that far off the road, in a paddock overgrown, without something being a bit suss, I don't think.
"It's not really a place you'd have an accident."
The Land Services SA Register shows the vacant block is owned by W.R. Williams Electroplasters Pty Ltd.
That company has the same registered business address as Mullins Wheels, located next-door on Chevoit Road.
Staff at Mullins Wheels today declined the ABC's request for comment.
Seeking information
Major Crime detectives are now seeking information from anyone who frequents the area.
Detective Inspector Brett Featherby addressed the media yesterday and said testing was underway to identify the remains.
"The circumstances around the identification is suspicious, Major Crime will be taking carriage of this investigation," he said.
"Any member of the public that may have seen someone acting suspicious around Salisbury South, in the proceeding months, please contact police or crime stoppers."
