London – Backpacker Grace Millane browsed a fetish website an hour before meeting the Tinder date accused of murdering her, a court heard on Tuesday.

Miss Millane, who died on a gap year in New Zealand on the eve of her 22nd birthday, had researched how to practise choking safely, an ex-boyfriend said in a statement read to the Auckland High Court.

A 27-year-old man, who cannot be identified for legal reasons, denies murdering Grace, claiming her death was an accident during rough sex in his apartment after they had met for their date in December last year.

He admits stuffing her body in a suitcase and burying it in a shallow grave in a wooded area outside Auckland, but said this was because he panicked.

Statements from police revealed that Miss Millane had memberships of several fetish websites and had been active on one of them an hour before meeting her killer outside a casino in the city.
