Where is Baby Tegan? It’s a simple question with a diabolically difficult answer. Is Tegan Lane dead or alive? She was last seen as a two-day-old being carried out of a Sydney hospital by her mother Keli, an aspiring Australian Olympian.

Instead there has been any number of theories and wild accusations, mostly to do with the bizarre behaviour of her mother, Keli Lane – sordid stories about sexual affairs and secret pregnancies. In 2010, Keli was found guilty of murdering Tegan, even though her body has never been found. Now, in a last desperate bid to prove she is not a baby killer, Keli’s parents, Sandra and Robert, break their silence.
