Disappearance baffles police
Blacktown police recently asked for anyone with any information about Mrs Matterson, even at this late date, to come forward. ``One of the people she had befriended was a man who people only knew as Tony,'' Detective Senior Constable Wayne Kelly said. ``He was described as a New Zealander, with a tan complexion not necessarily of Maori appearance and aged 25 to 30. Not long after Mrs Matterson disappeared, this man told people he was going back to New Zealand.''
Mr Kelly has been in charge of the investigation into Mrs Matterson's disappearance. ``After she vanished we did a search of Toongabbie Creek and found her handbag which had her wallet and other identification.''
He noted that Mrs Matterson did not leave with any packed clothes and that her bank account has not been accessed. As late as March this year the New Zealand media did a story about NSW police wanting to talk to a man called Tony but again no response,'' Mr Kelly said.
On August14, Mrs Matterson's case was listed in the NSW Coroner's Court.
Any information to Blacktown police, 96719199 or the Missing Persons Unit, 88357656 or 1800025091.
