Zvi Amiri, formerly Biton, was born to immigrants from Tunisia that lived in one of the immigrant absorption camps in the North. When the mother returned to Rambam Hospital in Haifa, where she gave birth to her premature baby and where he was left for observation, she was told that his strength failed him and he died. In fact he was delivered to foster care and then to childless parents from one of the kibbutzim of Hashomer Hatzair. His parents hid the fact that he had been adopted from him him for many years, and when he finally found his family he discovered that many tragedies had befallen them - all of them due to his disappearance.
The case was described by attorney Rami Tsubary in his book "In the Footsteps of My Lost Brothers."
