Murder investigations continue at a bikie property near Mannum today.
More than 70 police officers with horses and canines have been sweeping the 15 hectare property at Ponde owned by the Hells Angels.
Known for events such as sand drag racing and concerts, the property is thought to be housing evidence that could help solve two murder inquiries.
In 1999, three members of a rival bikie gang, the Rebels, were shot outside of their clubrooms in Adelaide.
Two Hells Angels members were arrested, but the charges were withdrawn due to a lack of communication by the Rebels.
In 2017, Mark Boyce was bashed and later died in hospital, a member of the Hells Angels was convicted, however, police believe more bikies were involved.
On Tuesday 17 September, two guns were found by police but authorities say they were not used in either murder.
It is hoped that a vehicle and guns will be found in the coming days to be used as evidence linked to the murder inquires.
Major Crime Detective Superintendent Des Bray says the property has been searched before, but this week's operation is far more extensive.
"This time we’ve received some specific information relating to these two murders and we believe if we put in the effort and conduct an intensive search of the property we may be rewarded," he said.
“We are aware this property has been used in the past and is currently being used to store illegal firearms,
“Those have been searched by mounted police, drug dogs, gun dogs and officers using specialist equipment as well as using an excavator to excavate those areas.”
