Two houses, three break-ins, violent attacks and more than $100,000 stashed away. Those circumstances led to the brutal killing of 72-year-old grandmother Irma Palasics. It was one of Canberra's longest-running cold cases, until a DNA match brought down the attackers. In 1999, two masked men broke into this Canberra house. The couple who lived there, Irma and Gregor Palasics, were bashed, gagged, and tied up. By the time the men left, Gregor was badly injured, and Irma was dead.
