Erika was a truculent teenager, her boyfriend, Omar, besotted by her. But everything seemed normal in the home of the De Nardo family in a small town in Northern Italy. Dad worked as an engineer, Mum as an accountant whilst Erika and her little brother, Gianluca, went to school. Nobody could know that Erika and Omar were plotting to slaughter mother, Susanna, and father, Francesco, before setting up home as parents to little Gianluca. But as Susanna returned home one evening, Erika and Omar first knifed Erika's mother to death and then chased Gianluca around the home. As he hid in the locked bathroom, they decided he too had to die. He had seen too much. The double-killers fled the scene claiming a burglary and murder by immigrants. But tell-tale, bloody footprints hinted at the truth of what had happened when Erika and Omar became the teenage killers.
