An air and ground search of bushland on Adelaide’s southern outskirts has found no trace of a man who was last seen alive in September when he apparently went bushwalking in the area with a friend.
Extended family members are worried because Glengowrie man Peter Glazebrook has made no recent contact with them, and police say they are unable to rule out foul play.
About 60 police officers and State Emergency Service volunteers spent Friday searching Onkaparinga River National Park for any sign of the 44-year-old man, who has a brain injury.
Detective Chief Inspector Charmaine Peters said police were told Mr Glazebrook and a companion went to the park to hike but apparently became separated.
“Peter was reported missing by a homeless service from the CBD about the September 15,” she said.
“They hadn’t seen him for a couple of weeks and they expressed some concerns.”
She said investigations locally and interstate led to recent information Mr Glazebrook might have visited the national park with another man.
“We do have concerns for Peter because of his ability to actually be out here, his ability to think on his feet and his capacity to look after himself.”
Police said the missing man had generally poor health and might have become disorientated.
Inspector Peters said water operations police were also checking waters in the gorge.
“The gorge is quite extensive [and] there are a fair number of trails we need to cover,” she said.
“If he’s in the national park I have concerns about finding him alive at this stage, but we are still being positive that he had left the national park.”
The park search might need to extend beyond a day, police said.
