ABC Local - Photo reveals man's gruesome nail gun death
The head of the Homicide Squad, Geoff Beresford, says the weapon has not been found.
"If anyone knows of a particular nail gun that has been stolen from them or from work premises, building sites, et cetera, we'd be grateful to hear that information," he said.
He says the victim had been in Australia for eight years, but has no family here.
"In 36 years of investigation, I've never come across a murder of this nature using a nail gun," he said.
