Images of a mobility scooter and a distinctive motorbike helmet have been released by police who are investigating the suspected homicide of a man at Mannum earlier this year.
Adrian Trett, 45, (pictured) was found unconscious and wrapped in blankets on David Street, Mannum early on Monday 23 April.
He was taken to hospital with a serious head injury, but never regained consciousness and died in the Royal Adelaide Hospital on 5 May.
Police announced in June that his death was being treated as a homicide, and appealed for assistance from the public to establish the full circumstances.
Late today the SA Police Major Crime Investigation Branch released images of a mobility scooter and helmet while appealing for further public assistance in the case.
Inspector Billy Thompson, the acting officer in charge of Major Crime, said police have seized a mobility scooter they believe is linked to the case for further forensic examination.
“We believe we have located the mobile scooter (similar to the one pictured), but we are seeking information about that vehicle and anyone who saw it around the time of Mr Trett’s death as we believe it was used to move him from an Asmus Street address to nearby David Street.”
Investigators are also making enquiries to locate a black motorbike helmet with a distinctive “8” emblazoned on the side, making the appearance of an eight ball, which was owned by Mr Trett.
“An associate of Mr Trett was captured on CCTV at the Mannum On the Run Service Station at 9.18pm on Sunday night (22 April) wearing the helmet and riding Mr Trett’s small motorbike, prior to the victim being found unconscious in David Street about 6.30am on Monday 23 April.
“Mr Trett’s motorbike was recovered alongside him in David St, however the whereabouts of the helmet at this time are unknown.
“Major Crime investigators are currently making enquiries with associates of Mr Trett relevant to this investigation in Victoria,” he added. “It is hoped that information provided by those associates will benefit the investigation.”
Police are keen to identify two or possibly three people – one of whom may have been a woman – who were seen attending to Mr Trett and wrapping him in blanket while he was in David Street.
