Keli Lane

Prior to finding a permanent home for this child, the Department of Community Services (DOCS) child protection worker, John Borovnik, made further investigations that led to finding that the child born in 1999 was in fact not Lane's first child and that she had given birth in 1996 at Auburn Hospital. Further investigations revealed that Lane had also given birth in 1995,[7] during her four-year relationship with Gillies. Gillies claimed he was completely unaware of Lane's pregnancies.[5] When confronted with these allegations in October 1999, Lane initially denied the existence of the two earlier children. Several days later, she claimed that her daughter was living with a family in Perth.[7] Concerned about the situation, Borovnik alerted the local police who began investigations in late 1999.

In February 2001, Lane, who by now was seven months pregnant with her fourth child, was interviewed by police.[7] During the police interview, Lane claimed that she had given Tegan to the baby's father, a man called Andrew Norris (or Morris), with whom she claimed to have had a brief affair. According to Lane, the affair took place at a unit block in Balmain on Friday nights after a drinking session at the Town Hall pub ("The Townie"). Lane alleges in her police interviews Norris's long-term partner, Melanie, also lived there as she often saw female apparel strewn around the unit. According to Lane, Melanie was in retail although she was not present at the unit on Friday nights.

During police interviews, Lane claimed that she felt forced to hide her pregnancies because of her fear of the reaction of her parents and friends as according to investigations she could not be sure who any of the fathers of the babies might be. She told police she handed the baby over to Norris in the Auburn Hospital car park but later changed this story to state it was inside the hospital foyer. It was reported that during the police interviews Lane said several times she felt alone when she became pregnant and told her mother in an intercepted phone call "I had no other choice", referring to why she gave baby Tegan to Norris.[7] Manly Police referred the matter to the New South Wales Coroner in 2005.

A coronial inquest into the disappearance of Tegan Lane began in June 2005 and ran until February 2006. The inquest was presided over by the State Coroner, John Abernethy, and heard that police had undertaken an extensive search for the child, including attempting to match DNA samples.[8][9][10] The inquest resulted in the coroner declaring that he was "... comfortably satisfied that Tegan Lane is in fact deceased..."[7] and that he was concerned that Tegan had met with foul play, although he also stated that there still existed a possibility that she was alive somewhere. The Coroner ordered that a birth certificate would be issued for Tegan and recommended that the brief of evidence and transcript of the coronial inquiry be forwarded to the New South Wales Homicide Squad for assessment and if necessary further investigation.[11]

From 2006, police investigations focused on locating Norris, Melanie (Mel), and Noeline (Nana) Norris, Andrew Norris's mother, all alleged to have participated in or witnessed carriage of baby Tegan from Auburn Hospital. Despite nine documented versions of what happened that day, it was reported that police were unable to locate any persons who matched those profiles. Sightings of Norris were reported at the Sydney Aquarium but discounted as according to Caroline (Carol) Meldrum Hanna on the ABC Exposed Documentary post screening, Lane had told her "Andrew had no interest in water".[12] Police also sought to locate Tegan Lane by searching the records of over 9,000 primary schools in Australia – a search process that lasted two years. Two girls named Tegan Lane were found in Queensland and another possibility was picked up on a Torres Strait island. Finally, police excluded all possible leads.[12][13]

The police investigators, assessing that they had no conclusive evidence or any physical evidence pointing to baby Tegan's death, decided not to charge Lane; however, they referred the matter to the NSW Director of Public Prosecutions (DPP), Nicholas Cowdery.[12] In what the National Times described as "an unusual step",[12] on 17 November 2009, the DPP charged Lane with the murder of Tegan Lane.[14] Lane pleaded not guilty, and the matter went to trial by jury.

The matter was heard in the Supreme Court; presided over by Justice Anthony Whealy; with Mark Tedeschi, QC as the Crown Prosecutor; and Keith Chapple, SC defending Lane under instruction from Legal Aid; and began on 9 August 2010.[12] The Crown alleged that Lane became pregnant five times over seven years during the 1990s; terminating the first two pregnancies,[15] placing two babies up for adoption, and allegedly murdering her baby, Tegan, on 14 September 1996.[5][7] The jury heard that Lane concealed her pregnancies from her family and friends in order to protect her personal image and reputation. According to Supreme Court judge Peter Hammill, who acted in her defence in 2006, images would have been destroyed by revelations of the salaciousness of her sex life centering around numerous rugby players from The Manly Marlins club over which Robert Lane presided.[1]

The evidence heard at the trial was similar to that presented at the inquest four years earlier. The major differences were the police searches that occurred in between, and the discovery that Lane had left Auburn Hospital not at 2 pm on the day Tegan disappeared, but several hours earlier.[16] The Crown produced evidence that, as a motive for murder, Lane was prepared to abandon her children at birth to increase her chances of representing Australia in water polo at the Sydney 2000 Olympic Games. There was also evidence she believed children would interfere with her educational plans, her social life, and the regard in which she was held by parents and friends. It was also alleged that her friends' wedding on 14 September may have been a crucial factor; as Lane sought a permanent solution to a potential problem to hide evidence of the pregnancy and birth from family and friends.[16] Lane's defence rested on the lack of evidence about how or where Tegan might have been killed. The defence claimed that, even if Lane had killed Tegan, the Crown could not prove she had done so deliberately or with the intention to kill.

On 13 December 2010, the jury found Lane guilty of lying under oath in relation to documents dealing with her adopting out two other babies.[1] The jury was not able to come to a unanimous verdict on the murder charge. Under advice from Whealy, the jury was given the option of returning a majority of 11 to one verdict.[16][17] A little later on the same day, the jury found Lane guilty of murder of Tegan Lane.[1] Lane was refused bail.

Sentence procedures commenced on 11 March 2011, again in the Supreme Court before Whealy, with the Crown calling for the court to pay particular regard to general deterrence.[18] It was reported that psychiatrist Michael Diamond, who appeared before the hearing on behalf of the Crown, found no evidence of a psychiatric disorder and that Lane's decisions appeared to be based on "problem solving".[19] On 15 April 2011, Lane was sentenced to 18 years' jail with a non-parole period of 13 years and five months.[2][20][21] She will be eligible for parole on 12 May 2024.[22]

Lawyers acting for Lane lodged an appeal against her conviction on 18 April 2011.[3] The same day, claims were aired in the media that a taxi driver saw Lane dump the baby in bushland, en route to Manly.[3][23]

Some news reports allege that, since being jailed, Lane has been bashed by other inmates, causing facial injuries. Lane has responded by denying such incidents.[24]

An appeal was lodged and was heard in the New South Wales Court of Criminal Appeal between July and December 2013.[25][26] The court dismissed the appeal, commenting that there was "ample" evidence available to the jury of Lane's guilt. Lane made a further application for leave to appeal to the High Court, and that application was rejected in August 2014.[27]
