As put by Detective Sergeant Lucy Aldridge
Christchurch Police are releasing the above CCTV images in a further appeal for information on the whereabouts of 79-year-old Elisabeth Nicholls.
These CCTV images of Lis were taken during her last confirmed sighting at the Chateau on the Park in Riccarton, at around 7.54pm on Wednesday 4 June.
Since Elisabeth was reported missing, searchers and Police have gone door to door, reviewed CCTV footage, searched the Avon River, and made further extensive enquiries, but we have not been able to find Lis.
Today, Police deployed a drone in the Riccarton and Hagley Park areas between 8am and midday. We are now in the process of examining these images and reviewing what was captured.
Police are urging residents in the nearby area who have not yet done so to please check their backyards, sheds and sleepouts, and anywhere where a person could seek shelter on your property.
We, alongside Lis' family, are seriously concerned for her wellbeing and are appealing to anyone with information to please contact us.
For anyone with CCTV, dashcam, or video footage in the Riccarton and Hagley Park areas between 6.40pm on Wednesday 4 June to 8am on Thursday 5 June, please review the footage you have and contact Police if you believe you see Lis.
When Lis went missing in the Riccarton area, she was physically strong, and may have walked some distance.
