Baby killer Keli Lane’s last hope of overturning her murder conviction has been lost, after the High Court rejected her bid to appeal.

Lane was found guilty in 2010 of murdering newborn Tegan within hours of leaving Auburn Hospital in September 1996 with the baby.

The 39-year-old water polo player then went to her parents’ home, before attending a wedding that afternoon.

She was jailed in 2011 for at least 13 years and five months for the murder of two-day-old Tegan, with a maximum term of 18 years.

Following an unsuccessful bid to overturn her conviction last year at the NSW Court of Appeal, Lane took her case to the High Court.

But on Friday, Australia’s highest court rejected her application for special leave to appeal.
