Chen Liu, who was also known as Anthony, had 30 nails gunned into his head. His body was found in Sydney. Mr Liu was bound with electrical wires and an extension cord and then rolled in a domestic rug with the ends neatly tucked in, which was then tied with three pieces of wire. “In 36 years of investigation, I’ve never come across a murder of this nature using a nail gun. May I say it’s a particularly brutal and vicious murder and we are seeking information from the public so we can bring this inquiry to a conclusion,” the head of the homicide squad, Geoff Beresford, said.
