A public meeting has been held in the home village of missing Janis Hall to discuss efforts to find her.
This weekend will mark one month since the grandmother vanished from her home in Catton, near Hexham.
And despite the launch of a large-scale search operation, what has happened to the 65-year-old today remains a mystery.
Supt Mick Paterson, of Northumbria Police’s Northumberland Area Command, said officers were now following up information from the meeting this week.
“I want to thank those who attended the public meeting in Catton this week in relation to the disappearance of Janis Hall,” he said.
“The meeting allowed us to gather information and reassure local residents about the heightened police activity in the area.
“The meeting was really well attended and the information we received may just give us the lead we need to help find Janis.
“I want to assure the local community that we are doing all we can to find her.”
Janis was reported missing just before 10.45pm on Thursday, December 19. She had last spoken to a relative on the phone at around 2pm that afternoon.
Extensive searches have been carried out every day since her disappearance.
Janis’ family say her disappearance is completely out of character.
She is a popular, well-known member of the local community and a keen walker.
But she had been down over recent months following the death of her husband.
Janis is described as being 5ft 4ins tall of medium build, with grey short hair.
She wears glasses and when she was last seen was wearing a green fleece coat, black trousers and a Russian fur hat.
Supt Mick Paterson added: “Officers are also continuing to carry out inquiries in the area and wider afield to try and establish her last known movements.
“I would continue to urge anyone with any information at all, no matter how small or irrelevant they may believe it is, to contact the police. It may just be the key information we need to find Mrs Hall.”
Anyone with any information that could help police with the search should call Northumbria Police on 101
