Homicide detectives investigating the murder of Dorothy Britton at Airlie Beach in 1996 have received new information about the case since their appeal in May.
The body of the 48-year-old woman was found at 6.30pm on Thursday, 7 March 1996 in her house at Timberlands Road, Jubilee Pocket, Airlie Beach.
Mrs Britton was last seen alive at about midday on the previous day and had died as a result of a gunshot wound.
Homicide Detective Senior Sergeant Chris Knight said police were confident that the offender had a close association with Mrs Britton, had extensive knowledge of her lifestyle and routines and was familiar with her loyal and protective Rottweiler dog, Bella.

“We need public assistance to solve this
