A person who made contact with Crime Stoppers last month appears to have valuable information in line with police inquiries into a 30-year-old unsolved murder in Whyalla.
Whyalla businessman Peter Seaford was brutally murdered in his own home in the early hours of March 12 1989, with the takings from the service station he part-owned stolen.
Police are calling on a person who contacted Crime Stoppers last month with some information about the death to make contact with them again.
Detective Senior Sergeant John Schneemilch said the information the caller provided suggested they have knowledge of the murder.
“I think it would be fair to assume they either live in, or have lived in Whyalla, given the nature of the information," he said.
Police believe Mr Seaford may have been killed after he fought with an intruder, pulling off a home-made balaclava and possibly identifying his attacker.
"The injuries he's suffered show this was a sustained attack and he's fought back," Detective Schneemilch said.
The investigation has seen recent progress under the auspices of Operation Persist, with items sent for further forensic testing due to developments in the area of DNA.
This work led experienced investigators from the SA Police Major Crime Investigation Section to visit Whyalla last year and they are currently awaiting additional results from Forensic Science SA.
“I’m confident this investigation in moving in the correct direction. It’s hard to talk about what the outcome will be given the passage of 30 years, but we know that the right piece of information can be vital in these kinds of circumstances," Detective Schneemlich said.
A reward of up to $200,000 will be paid by the SA government to anyone who provides information that leads to the conviction of the person or people responsible for Mr Seaford's murder.
