Detectives investigating the murder of an elderly Hampshire woman have set up an online casebook.
Police want to reach as many people as possible with their appeal
Georgina Edmonds, 77, was murdered at her home in Kiln Lane, Brambridge, on 11 January.
The police casebook includes details of the incident, a map showing key sightings, e-fits and CCTV images of people the police want to talk to.
Officers made a significant find last week when they discovered Mrs Edmonds' mobile phone near the River Itchen.
Det Ch Insp Paul Barton, of Hampshire Constabulary, said: "This casebook is a place for people to go to find out more information about the murder of Mrs Edmonds.
"The launch of this casebook means that members of the public can now give their information to us via email by using the link in the 'can you help' box.
"We want to make sure we use all sources available to get our appeal across to as many people as possible.
"This remains an active investigation and we still need help from the community.
"I would encourage people to have a look at the website to see if they have any information that they think may help us."
Post-mortem tests showed Mrs Edmonds died of extensive head injuries.
Her daughter, who works as a nurse in Kenya and Sudan and has since returned to England, appealed for help in finding her mother's killer.
A distinctive key fob, Mrs Edmonds' cash card, cheque book and handbag have all been missing since the killing.
Officers began searching a house in Twyford Road, two miles from where Mrs Edmonds was killed, two weeks after her death.
Four men were arrested on 14 January. Three were released without charge while a 37-year-old man was released on bail.
