The evidence that could clear Keli Lane: Prosecutors say 163 babies were unaccounted for when little Tegan vanished - and admit she could still be ALIVE
- The revelations come from an investigative team looking into the Keli Lane case
- Ms Lane was jailed for 18 years in 2010 after being found guilty of killing her baby
- But baby Tegan was never found and prosecutors cannot rule out her being alive
- The investigation also found 8,000 births a year went unrecorded in the 1990s
As many as 163 untraceable children were not taken into account during the search for Keli Lane's daughter Tegan as later as the mother's murder trial.
Lane, who is now 43, was jailed for 18 years in 2010 after she was found guilty of killing her newborn baby Tegan in 1996. The infant's body was never found.
The convicted murderer has denied killing her daughter, and has raised the possibility Tegan could still be alive during the three-part ABC documentary series Exposed broadcast in September and October.

Following the series' conclusion, ABC's investigative team led by journalist Caro Meldrum-Hanna revealed the NSW Office of Public Prosecutions (ODPP) told them they too could not rule out the possibility Tegan was still alive.
Their research found 8,000 births went unregistered each year in the 1990s - poking a hole in the prosecution's investigation.
At the time of Lane's trial, Crown prosecutor Mark Tedeschi QC said in documents he feared the murder trial would be discontinued because of the 'gap' in evidence.
Assistant registrar for the NSW Registry of Births, Deaths and Marriages Sharon Swinbourne told the investigation 'you can't turn around and say yes (the search) was absolutely thorough', ABC revealed.
RMIT University's Innocence Initiative, meanwhile, has formally applied for a review of Lane's murder conviction to the NSW attorney-general.

The latest revelations come after the man who spearheaded the murder trial against Lane apologised for calling the baby killer a 'risk to virile young men' during the television exposé.
Nicholas Chowdery, former New South Wales Director of Public Prosecutions, admitted some of his comments were out of line in the ABC documentary series.
'She seemed to be a bit of a risk to the virile young male portion of the community,' Mr Chowdery said on the program.

Mr Chowdery, who is now the chair for The White Ribbon Foundation, issued an apology which wrote: 'We are all accountable for the language we use, and the impact it has'.
In a statement, he acknowledged the comments he made about Ms Lane in the documentary to be disrespectful.
'White Ribbon Australia's chair acknowledges that his comments and response to questions about Keli Lane on ABC documentary Exposed were not respectful, and he apologises,' a statement released by the foundation read.
'Mr Cowdery supports the need for every person to be mindful of the language that they use and the meaning it can have.'
But Chief Executive of White Ribbon Tracey McLeod hit back on Twitter, claiming Mr Chowdery's apology was 'not acceptable' and a 'a robust' discussion was necessary.
'Apologies to Keli Lane particularly and women everywhere,' she added.

Lane was convicted after it was revealed she had lied about three secret pregnancies, which led to two adoptions, and the disappearance of one child.
The former water polo player fell pregnant three times in four years without letting anyone know, including her partner.
The three-part documentary alleged Lane was sexually assaulted a number of times as a teenager, which explained why she repeatedly fell pregnant.
