The mother-of-two who mysteriously went missing nearly three months ago could have been murdered, according to a close family member.
Madeline Bigatton was captured on CCTV getting into her car in the driveway of her family home at Carss Park, in Sydney’s south, on the morning of March 25.
The 48-year-old then dropped her daughter at a friend’s house nearby, and is believed to have driven up to Kurnell, where her black Kia Sorento was found parked later that night.
A relative close to Mrs Bigatton said the family considered a plethora of explanations for her disappearance, including suicide, murder, or that she had run away, news.com.au reported.

The wife of international Bitcoin entrepreneur John may have even taken matters into her own hands to escape crushing financial trouble, the relative also suggested.
The missing mother reportedly told a neighbour the family was low on money before she disappeared, but other sources suggested the opposite was true.
The neighbour was collecting money for the National Heart Foundation when she visited her Erang Street mansion, to be told ‘We don’t have a cent to spare.’
They bought the property in 2006 and knocked down an old brick home to build a two-storey mansion with multiple wings.

‘She was just so loved, the church was completely packed out,’ he said.
‘It’s just so not like Madeline (to go missing). She was brought up in cotton wool, she was one of those real sort of good girls who never put a foot wrong her whole life.

An extensive search of the Kurnell area was conducted after her disappearance, with rescue helicopters, Marine Area Command and the Dog Unit involved.
