It was the Australia Day weekend 1996.
Perth woke to the shocking news that an 18-year-old had been reported missing after not returning home from a night out in Claremont with friends.
Little did we know that her disappearance would be just the beginning of Australia's most expensive and longest running investigation.
She was the first victim of the Claremont Serial Killer, but her body has never been found.
In this bonus episode, we're joined by veteran journalist Alison Fan, who became close to the Spiers family since their daughter and sister was reported missing. Alison recounts the desperation felt by Sarah's heartbroken family to find the loving and happy young woman.
We take you through the person Sarah was, the search for the 18-year-old and the torment her family has gone through in the 24 years she's been missing, including false hopes and clairvoyants giving them leads that went nowhere.
As WA's trial of the century continues, the Spiers family say they've never given up hope of finding Sarah.
Join Natalie Bonjolo, Alison Fan and Tim Clarke as they remember Sarah.
