The fiancé, family and friends of Stephanie Scott have visited the high school where she taught, in a special vigil to remember the 26-year-old.

Aaron Leeson-Woolley and Ms Scott's sister Robyn Scott led a group of loved ones to spend a few moments at a memorial created by local students.

The close-knit town of Leeton is mourning the death of the popular teacher, who went missing just days before her wedding.

Today, grief-stricken students, parents and members of Leeton community left notes with heartfelt messages reading:

"We will miss your beautiful, funny, caring nature"

Student Bianca Lotto said, "She was amazing. The only person you'd probably go to and actually speak to, she'd understand everything".

Yesterday, police arrested Vincent Stanford and allegedly found photos of a burnt body in his phone and blood in his ute.

Police have not yet found Ms Scott's body but believe Mr Stanford knows where it is.

At Griffith Court today, Mr Stanford did not appear and didn't apply for bail, which was formally refused by Magistrate Kate Thompson.

“This is tragic, it’s tragic for the family, it’s tragic for the people of Leeton and it’s tragic for the people of NSW,” Superintendent Michael Rowan from NSW Police said.

Today, neighbours described the 24-year-old cleaner as a quiet, unassuming man who kept to himself.

"We invited them in for a cup of tea a couple of times," Gail Scanlan said.

"The family kept to themselves.

"He was very unassuming."

Her husband Bill Scanlan said the family moved next door about 12 months ago after returning to Australia from their native Holland.

Mr Scanlan said Stanford lived there with his mother, a nurse, and another male.

Police have found a car that they suspect is Ms Scott's red Mazda in a paddock off Griffith Road approximately 8.5km west of the town of Leeton where she was last seen. It has been secured as a crime scene and will be processed throughout the day.

A police spokesman said investigators were appealing for information about the movements of a white Toyota Hilux space-cab 2WD with a canopy over the back travelling in Leeton or the surrounding area over the past few days in the hope it may help them find Ms Scott's body.

Stephanie Scott was due to be married this weekend.

"We don't know where her body is at this time," he said.

He said it was too early in the investigation to determine whether further charges would be laid or if Mr Stanford had any alleged accomplices.

Ms Scott, a 26-year-old English and drama teacher at Leeton High School, was due to be married this weekend to her partner of five years, but disappeared from the town on Easter Sunday.

She was last seen at the school on Myrtle Street at about 11am where it is understood she was planning the lessons that would be taught while she was on her honeymoon.

At 1pm she sent an email to the bus company she had hired for her wedding.

Ms Scott was reported missing to police on Monday and detectives from the Griffith Local Area Command formed Strike Force Gundibri to investigate her disappearance.

Yesterday evening, officers attended a home on Maiden Avenue, Leeton, where they spoke to two residents. Around 7.30pm, Mr Stanford arrived at the property.

He was subsequently arrested and taken to Leeton Police Station.

Mr Stanford will likely appear before Griffith Local Court later today. A crime scene has been established at his house.

Police said he had lived in the area for 13 months.

Ms Dooley said Stanford was employed as a casual in October 2014.

"Our thoughts are with Stephanie's family and friends and the Leeton community," she told AAP.

"We have also made contact with and are assisting police at the moment."

Ms Dooley said Stanford passed all the necessary checks when he started with the company.

The company is reportedly contracted to clean more than 1000 schools across New South Wales.

Officers ask that anyone who may have seen Ms Scott or her car – a red Mazda 3 sedan with registration BZ-19-CD – contact police.

Anyone who was in the vicinity of Leeton High School on Sunday is also encouraged to contact Griffith Police on (02) 6969 4310 or via Crime Stoppers on 1800 333 000.

As police investigated her disappearance throughout the week, both her fiance Mr Leeson-Woolley and her family insisted she did not simply have cold feet.

Mr Leeson-Woolley said it was "right out of the blue and not like her to do this".

"I just want her to be here so we can get on with the stuff we need to do," he said.

"She's my life now. No one would understand how much [I miss her]."
