Khandalyce's birth certificate reportedly found at home linked to accused killer

Police allegedly found the birth certificate of murdered girl Khandalyce Kiara Pearce at a house linked to her mother's accused killer last month, it has been reported.

The remains of two- year-old Khandalyce were found in a dumped suitcase on the side of a highway near Wynarka in South Australia in July, while the body of her mother Karlie Pearce-Stevenson was found in the Belanglo State Forrest in 2010.

The man accused of murdering Ms Pearce-Stevenson, 41-year-old Daniel James Holdom, is alleged to have killed her in the forest in December 2008.

Last month it was revealed the two cases were tied together, and on the same day police announced the link Fairfax Media reports detectives searched the home of Mr Holdom's sister after a tip-off, locating Khandalyce's birth certificate.

In late October police revealed Ms Pearce-Stevenson's identity, bank account and mobile phone were used for years after her death to mislead family and defraud social services.

It was estimated up to $100,000 was taken from her bank account between 2008 and 2012.

A woman in a wheelchair also impersonated Ms Pearce-Stevenson in a Centrelink interview in 2010.

Mr Holdom's former girlfriend Hazel Passmore, who uses a wheelchair, has been questioned several times but has not been charged with any offence.

Ms Passmore was first questioned after photos of Khandalyce Pearce were found on her Facebook page.

The page was disabled soon after but one photo pictured the blonde-haired child standing in an automotive display garage in front of a car with the hood propped open.

The photos were dated August 2008, several months before police believe the mother and daughter were killed.

Mr Holdom is due to appear in Central Local Court in Sydney later today.
