Chinese immigrant Chen Liu, 27, was killed in Australia in 2008. His body, tied up with electrical wire and wrapped in a rug, was found in a marsh by two children. He had been shot in the head 34 times with a nail gun. Detectives said the nail gun was a standard cordless, high-powered tool that shot 85mm long nails. “In 36 years, I’ve never seen a murder of this nature,” said Homicide Squad Superintendent Geoff Beresford.
