WA police commissioner Col Blanch says it's wrong to say police did nothing in response to warnings by the Bombara family about double murderer Mark Bombara. Bombara shot dead mother and daughter Jenny and Gretl Petelczyc on Friday in their Perth home, after thinking his wife would be there. The daughter of the gunman says she tried to warn police three times and felt let down by their response. An internal investigation is now underway.
