Western Australia’s premier says more needs to be done to combat domestic violence after the “chilling and horrific” murder of a mother and daughter by a gunman searching for his ex-wife, though police say they cannot classify it as a family violence matter.

Cook also said he would consider strengthening WA’s tough gun laws, which were recently updated and are in the process of passing through the parliament.

The gunman, 63, shot Jennifer Petelczyc, 59, and her 18-year-old daughter, Gretl, on Friday at their Floreat home, where his ex-wife was believed to have been staying, before taking his own life.
