Mary Berrington's family cling to the grainy CCTV footage of her walking in an Upper Hutt street just after midnight.
It is the last time she was seen since she vanished from her home almost a year ago.
When Berrington's family discovered her disappearance the following morning on July 20, her bedcovers were thrown back and the front door to her home was locked.
There was no sign of a struggle with the 62-year-old who was known to have bipolar disorder and a mental impairment.
Susan Geerars would later watch as DNA samples were taken from her mother's hairbrush and fingerprints collected from her home.
"We don't have a body, we don't have a grave site, so I thought it would be a nice place to sit and reflect on my mum's life and try to be at as much peace as we can", she said.
Geerars said she carried on for her two children.
She said her 4-year-old son recently asked her if his grandmother was dead and she told him she did not know.
"Maybe one day there's going to be a phone call and it's going to be her but just being this far on we know that there's pretty much no hope now.
"We're just trying to move forward the best we can. It's just absolutely life-changing to have her gone so suddenly."
At the time of Berrington's disappearance police never publicly released the CCTV footage of her walking past the corner of Fraser Crescent and Fergusson Drive at about 12.30am.
Geerars said her mother did not show up on cameras further down the road.
"It's really weird."
She said she had no idea what happened to Berrington but plenty of theories had circulated.
Did she step into the Hutt River and get washed away into the ocean? Did she hide somewhere she would never be found? Was someone else with her that night?
