Police are following “positive lines of inquiry” in the homicide investigation that was launched following the death of a Khandallah woman last week.

Detective inspector Nick Pritchard said police have been conducting inquiries over the past five days in the Baroda St area and at the home of 79-year-old Helen Gregory who was found dead on January 24.

“A scene investigation at the address is ongoing.”

Pritchard said police wish to assure the community that they believe it was an isolated incident and that there is not thought to be ongoing risk.

“Police wish to thank everyone who has come forward with information to assist with enquiries and we wish to reiterate the appeal for information.”
