Grace Millane's murderer 'tested theories' on Tinder date hours after backpacker's death, woman says

It was in the afternoon of December 2 that the man met up with another woman he had met on dating site Tinder, who described their date in court and has written a column for Newshub.

"My instincts told me something was not right with this man and, while it took me a long time to write this, I want to share my experience so other women can remove themselves from situations they feel unsafe in," the woman wrote.

She was struck during their date in the Auckland suburb of Ponsonby by how clean the killer appeared, his eagerness to talk about venomous snakes and his big eyes.

He also referred to buying a suitcase - in which Ms Millane's body was later found buried in a shallow grave outside Auckland - but being frustrated that it was not large enough to fit his sport equipment.

The killer mentioned his best friend, a Crown prosecutor, was moving from Sydney to Auckland, which interested his date who referred to her previous career as a court reporter, including on a murder trial.

He then said something that seemed strange to her: "It's funny how guys can make one wrong move and go to jail for the rest of their lives."

"In hindsight, it was as if he was using this date to process what he'd done in a rather roundabout way - his brain needed to get it out but his mouth held him back. Was he testing theories on me to see which version seemed most believable?"

The 27-year-old man, whose name is still protected by a court order, was found guilty on November 22 of strangling the young woman from Wickford, Essex.

The jury of seven women and five men returned a unanimous verdict after just five hours deliberation at Auckland High Court.

The Crown successfully argued the man, whose name is subject to a suppression order, strangled her and shoved her body inside a suitcase before burying her in a forested area outside Auckland.

She was assumed missing and her father, David Millane, flew to New Zealand as local authorities spent a week searching until her body was found by police.

Mr Millane and Grace's mother, Gillian Millane, wept after the verdict was delivered, as did several jurors.

Mr Millane said: "Grace was our sunshine and she will be missed forever."

Police officers said during the trial that phone data showed the killer had used Google to browse websites for large duffel bags, suitcases and car hire after Ms Millane died.

The defendant's phone was also used to search for "flesh-eating birds" and "are there vultures in New Zealand?".

Records showed the defendant had searched online for "the hottest fire", "large bags near me" and "Waitakere Ranges".

He will be sentenced on February 21, 2020.

He faces life in prison with a minimum of 10 years without parole, though the judge can increase the latter period.
