Homicide Squad detectives are today joining with family members to appeal for further information following the murder of Vicki Ramadan in Sydenham in April.
The 77-year-old was discovered by a neighbour inside her Marlborough Way home on Saturday 6 April about 9.45am.
Investigators have confirmed Vicki died after being brutally attacked.
Detectives now also believe that she died in her home sometime between 23 March and 6 April, 2019.
A squat premise near to Vicki's home was previously reported as an active line of enquiry for investigators, however this is no longer the case.
There is nothing to indicate any person associated with that premises is involved with Vicki's death at this time.
An active line of enquiry remains a dispute Vicki reported to police on 23 March.
Detectives have re-visited the crime scene a number of times over the past five months in the hope of learning more about the circumstances surrounding Vicki's death.
They have also continued to conduct forensic testing on items within the crime scene.
Vicki was often seen walking to locations and was known to use public transport, in particular buses and taxis.
Vicki was a well-known member of the local community and she had close relationships with a number of local traders and neighbours. She would often stop to speak to them or have coffee with them.
Officer in charge of the Homicide Squad, Detective Inspector Tim Day, said there will be someone in the community who knows why Vicki was killed.
"Vicki would always generate conversation wherever she went," he said.
"She was known to be very friendly and would always chat to local shop keepers especially in the Watergardens area.
"The dispute remains a significant line of enquiry for us and there is every chance that Vicki has discussed this with someone.
"We are particularly keen to speak to any of the local traders who had a discussion with Vicki just prior to her death about a dispute she was involved in, especially who the dispute was with and what it involved."
Detective Inspector Day said Vicki's death had left her family without answers.
"This is one of the most vulnerable members of our community who had been brutally murdered in her own home," he said.
"Homicide Squad detectives have spent a considerable amount of time in the area near the crime scene and we've been able to progress a number of lines of enquiry.
"We do have a suspect and this person has already been spoken to a number of times.
"If there is anyone who believes they have information that could assist police, we urge you to come forward."
Detectives are urging anyone with information to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
