Notorious paedophile Michael Guider who killed schoolgirl Samantha Knight has died in hospital – as he takes his evil secret to the grave

A twisted paedophile who was found to be responsible for the death of schoolgirl Samantha Knight has died in custody. 

A Department of Correctives NSW spokesperson confirmed Michael Guider, 73, died at the Prince of Wales hospital on Saturday morning about 7.25am. 

Daily Mail Australia understands he suffered a medical episode.

‘As a matter of protocol, Corrective Services NSW and NSW Police investigate all deaths in custody regardless of the circumstances,’ the spokesperson said.

Guider kidnapped Sydney schoolgirl Samantha Knight from her Bondi home in 1986 and drugged her, which resulted in a later conviction of manslaughter.

He also preyed upon other children across two decades and has shown no remorse for Samantha’s manslaughter, which he once claimed was accidental and recently said he had not committed.

Guider was let out of jail in 2019 but re-arrested in 2022 for breaching conditions relating to his five-year extended supervision order.

He has never said where he left schoolgirl’s body – with her location unlikely to ever be revealed with his death. 

Michael Guider kidnapped, drugged and killed nine-year-old school girl Samantha Knight in 1986. She was snatched from near her home at Bondi and her remains have never been found 

For the first six months of his freedom in 2019, Guider was holed-up in a secure facility attached to the Long Bay prison complex along with other offenders too problematic to return to society. 

But in March 2020 the loathed paedophile was quietly moved out of the Nunyara Community Offender Support Program centre at Malabar and placed in new permanent accommodation.

That angered and frustrated some of Guider’s surviving victims, who said at the time authorities had refused to reveal where their tormentor was now living. 

Guider’s younger brother Tim had previously warned his sibling would have used his time in Nunyara preparing himself to commit sex crimes on prepubescent girls again.  

After his initial release Guider refused to receive letters, phone calls or visits from anyone, including Tim. 

‘His minders have said to me he doesn’t want contact with anybody from the outside world,’ Tim said in 2019. 

‘He’s trying to keep his secrets basically. He doesn’t want anyone to know where he is or what he’s doing.’ 

Tim predicted Guider would have altered his appearance before he left Nunyara, including removing the long grey beard he grew in 2019.
