I came across the following page that mentions the murder: http://commons.wikimedia.org/wiki/File:Murder_Memorial_Queen_Street_01.jpg
It's a photo of a memorial that someone left on the steps of the Westpac branch that is on the corner of Queen Street and Karangahape Road in Auckland. The description of the photo reads:
A little personal memorial for a murder victim that someone had put next to the doorway of the Westpac Bank at the top of Queen Street / Karangahape Road, Auckland City, New Zealand. A young Essex woman was apparently slain on these steps 21 years ago, and the unknown person (who apparently did not know her well, or at all) wonders about why it had to happen and what could (or in a way, has) become of her. I made sure that the little memorial stayed put a little longer (the tape had already almost given out). Very touching and sad.
But that's all the info I have about the murder. There's a date of June 2008 on that page, but I don't know if that's the date the photo was taken (which would mean that the murder probably took place in 1987 if the "21 years ago" is correct) or just the date the photo was uploaded (which could have been years after it was taken, making the "21 years ago" of no help in pin-pointing the date of the murder).
I've tried Googling to find out more about the murder but can't locate a single thing that talks about a murder in that location.
Does anyone remember this murder? Or can track down any extra info about it?
