In 1984, the Tapp family made a home at 13 Kelvin Drive in the Melbourne suburb of Ferntree Gully, Victoria, Australia. It’s been described as a safe, peaceful suburb with a near-zero crime rate.
Â
35-year-old Margaret Tapp thought it was the ideal place to raise her two children, 9-year-old Seana and 14-year-old Justin. She’d been divorced from her husband, Donald Tapp, for about 5 years and was forging ahead with building this new life for herself and her children. She worked full-time as a nurse and was in her third year studying law full-time at Monash University. Her goal was to combine her work experience to specialize in medical malpractice cases.
Â
But before she could realize all these dreams, before she could see her kids graduate and start families of their own, it all came crashing down.
