For days her fiance, Aaron Leeson-Woolley, and her family painfully begged the public for answers, completely stunned and at a complete loss as to Ms Scott's disappearance. Her family were adamant it was not a case of cold feet. Ms Scott's sister, Robyn, has told Fairfax Media that her sister was incredibly excited about her upcoming wedding. "I spoke to her on that Saturday night, and she was over the moon, she was so excited. She had been to Griffith that day shopping and getting ready for the honeymoon," she said at the time.

The court heard that two of Stephanie Scott's rings were sold for $705 by Marcus Stanford. But as police would later discover, someone else was at the school that Easter Sunday - even though he was not rostered on to work. School cleaner Vincent Stanford, 25, sought out Ms Scott, before sexually assaulting and murdering her. Stephanie Scott's sister Robyn leaves court in Sydney.

On Wednesday, Stanford pleaded guilty in the NSW Supreme Court to the aggravated sexual assault and murder of Ms Scott. Vincent Stanford's twin brother Marcus pleaded guilty at Griffith Local Court to being an accessory after the fact to murder in March this year.

Ms Scott's family showed little emotion as he said the words "guilty" to both charges, before Justice Robert Allan Hulme. Ms Scott's mother, Merrilyn, wore a yellow scarf and her sister Robyn carried a yellow handbag. Yellow was Ms Scott's favourite colour.

The family declined to make a comment outside court. Stanford's guilty plea came after his twin brother, Marcus Stanford, pleaded guilty at Griffith Local Court to being an accessory after the fact to murder in March this year. The police charge sheet stated that Marcus "did assist" his identical twin brother Vincent by receiving some of Ms Scott's personal items in the mail. Police arrested and charged Stanford days after Ms Scott's disappearance and after discovering he had taken photos of her burnt remains. He had dumped her red Mazda in a field just outside Leeton before transporting her body to Cocoparra National Park, just north of Griffith where he went on regular camping trips.

Police divers found Ms Scott's school-issued laptop, dumped in a canal. It is understood police used a triangulation based off Stanford's phone to narrow down a search area for Ms Scott's body. Stanford's mother, Anika, and other brother, Luke, helped police with their investigation. Ms Scott's body was found the night before she was due to be married at Eugowra in front of 100 close family and friends. Instead of wearing a tux and watching his partner of five years walk down the aisle on Saturday, April 12, Mr Leeson-Woolley wore Ms Scott's favourite colour and cried in the middle of a Riverina park with hundreds of people who knew and loved his fiancée.

Her father, Bob, told the crowd of hundreds gathered in Mountford Park that he wanted his daughter to be remembered for the great girl she was - and not in the tragic way she was taken away. "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." Few people in the small town of Leeton – population 7000 – had ever heard of Stanford before Ms Scott's murder. Bill and Gail Scanlan lived next door to Stanford and said they had waved to Mr Stanford over the fence of their Maiden Avenue home on Easter Monday, the day after the murder. "We heard him come back on Monday, did all the washing, hung it all on the line, piles of it," Mrs Scanlan said.

"He was a nice enough sort of bloke, clearly a loner, he kept to himself," Mr Scanlan said. Stanford also had a secret online life, hiding behind fantasy characters to indulge his obsession with computer games, violent videos and neo-Nazi propaganda. Loading Posting under the moniker of the mythical Aztec serpent Quetzalcoatl, Stanford posted on gaming forums that he "loved stargate and video games" and did "a bit of 3d modelling in my spare time". Stanford's sentencing hearing is expected to take place at Griffith on October 11.
