"How much grief can one family endure? This is terrible news. I'm so sad for this family," said another.
"This is so sad. I cried when I first heard it ... I don't know how one family could deal with this much heartache," another added.
“What more heartbreak does this loving family need to endure? I’m so very sorry for another tragic loss for you all,” Jennifer Lou wrote on Facebook page Rest In Peace Stephanie Scott.
"Whenever any of you think you might be feeling down, or going through some harship in your life, just imagine what some families have to endure," Cassie Stefanatti wrote. "Really puts life into perspective. I cannot begin to imagine the pain and suffering."
Mr Scott was pictured throughout his daughter’s murder trial, standing next to his wife Merrilyn as she read out a powerful victim’s impact statement.
Following the trial, Merrilyn Scott spoke about the "harrowing" 18 months she and her family had endured.
"So much has been taken away from us. Stephanie has had everything taken away from her," she said. "Losing her has shattered so many lives and we are all struggling with the consequences."
Soon after her death, Bob, as he was affectionately known, spoke to a crowd of hundreds gathered on what would have been Stephanie's wedding day.
"Unfortunately, she was taken away from us for a short time but now we've got her back and we will restore her dignity," he said as he stood by his family.
"Stephanie was a bubbly, bright, witty, intelligent fun-loving girl who has obviously impacted on many people here to today and our wishes for the future are that that will continue in your minds. You remember her as the girl she was and I'm sure wherever she is now that she would wish that to be the case and maintain that as you remember her, as that great little girl she was."
