The cleaner accused of killing Stephanie Scott was a loner rejected by the Dutch Army, his ‘father’ has revealed.

Police allege Vincent Stanford, 24, killed the teacher on Easter Sunday before dumping her body in an isolated national park in NSW.

“All he did was play computer games in his room,” said Richard Antonisse, who became a father-figure to the accused murderer when he was a teenager.

Then-16 year old Stanford, who reportedly returned to his native Australia 10 months ago, was disinterested in school and work, Mr Antonisse told News Corp from his home in the Netherlands.

“All he had was his work, his games and his animals.

“He loved animals. They had about nine cats in that house. It was like a pigsty.”

Mireille Antonisse said she and her husband tried to encourage Mr Stanford to be more social while he lived with them in Holland.

“We tried to help him become more of a person,” Mrs Antonisse said.

“Vincent missed out on having a father and Richard became his father figure.”

After working for the Antonisse family for six months, the alleged killer departed to join the Dutch Army, but returned when his application was rejected on medical grounds.

Mr Stanford abruptly ended his employment in 2010, and the couple said they never spoke to him again.

The 24-year-old is said to have lived in an online fantasy world, with digital traces on his seized computer revealing he watched Nazi propaganda and German military marches.

He is due to appear in court in June.

An autopsy is currently being conducted on Ms Scott’s body as police try to determine her cause of death.
