UPDATE: Since recording this episode, murderer and serial paedophile, Michael Guider, the man responsible for Samantha's death, has been released from jail.

When Tess Knight got home on a winter’s night in August of 1986 her nine-year-old daughter Samantha was nowhere to be found.

It wasn’t until 14 years later in February 2001 that a man named Michael Guider pleaded guilty to the manslaughter of the young Bondi school girl.

Guider, who was serving a sentence at the time for 60 child sex offences, told law enforcement that he had abducted and assaulted Samantha and in the process accidentally killed her.

Her body has never been found.

Journalist Mark Morri was a reporter at the time of Samantha’s disappearance, and developed a close relationship with the young girl’s mother, Tess. He joins Jessie for this episode to take us through the case, and the emotional toll it has taken on a mother who has never been able to know what happened to her daughter.

Michael Guider has almost served his full sentence for the charges laid against him, and unless a judge intervenes, he could walk free in the coming days and weeks.
