Today on Crime NZ we're looking at a case which shocked the world and involved an international manhunt.
In September 2007 a three-year-old girl was found abandoned at Melbourne's Southern Cross railway station.
Initially authorities were unable to verify her identity, so they gave her the nickname "Pumpkin" after the pumpkin patch branded clothing she was wearing.
But "Pumpkin" was actually Qian Xun Xue, whose father Nai Yin Xue had abandoned her at the train station before fleeing to the United States.
What the authorities didn't know at this point is that he'd murdered her mother Anan Liu back at the family home in Mount Roskill, Auckland.
Simon Scott was the Detective Senior Sergent in charge of the case, he talks to Jesse about the complex case which involved authorities in three countries.
