Stephanie Scott: Viagra, knife purchases among evidence against alleged killer Vincent Stanford.

Email invoices for the purchase of cleaning products, Viagra, a knife and plastic handcuffs are among the evidence tendered to a New South Wales court against a man charged with the murder of high school teacher Stephanie Scott.

Ms Scott, 26, disappeared on April 5 — Easter Sunday last year — just days before she was due to marry.

Her burnt body was found five days later in the Cocoparra National Park, about 70 kilometres from the town of Leeton, where she worked as a teacher at Leeton High School.

Vincent Stanford, a 25-year-old cleaner at the school, was arrested four days after her disappearance and charged with murder and aggravated sexual assault occasioning actual bodily harm.

Today, that sexual assault charge occasioning actual bodily harm was replaced with aggravated sexual assault and deprivation of liberty.

Stanford has been committed to stand trial for rape and murder.

Earlier today, his twin brother Marcus Stanford pleaded guilty to being an accessory after the fact to murder.

Four volumes of evidence were tendered to court for Marcus Stanford and 16 volumes for Vincent Stanford.

Among the evidence tendered against Vincent Stanford were email purchases for Viagra, cleaning products, a training sword, a knife and plastic handcuffs known as “flexi cuffs”, as well as an email with an enquiry about legcuffs.

The invoice for Viagra was tendered along with pornography and dating site URLs.

Recordings of phone conservations between the twin brothers was among the evidence, as was a number of Facebook conversations by the men, but which were not between each other.

A Jetstar boarding pass formed part of the evidence against Marcus Stanford, although it did not specify where or when the flight was taken.

Vincent Stanford committed to stand trial

Vincent Stanford did not enter a plea, but based on the evidence presented by the prosecutor the magistrate ruled the case was capable of resulting in a conviction before a jury, and he was formally committed to stand trial.

His lawyer applied for an adjournment on the grounds of an “outstanding assessment”, but that was denied and he was committed for arraignment in the Supreme Court on May 6.

Vincent Stanford appeared agitated at times and did not address the magistrate himself, with his lawyer answering on his behalf.

Marcus Stanford was arrested and charged in June and extradited from his home in Forreston, South Australia, to NSW.

The brothers appeared in Griffith Local Court.

Ms Scott’s mother, father, sister and fiance, Aaron Leeson-Woolley, were in court and did not react to Marcus Stanford’s guilty plea.

He appeared wearing prison greens and was polite and prompt when answering the magistrate.

Marcus Stanford is expected to be sentenced in May.
