After the trial of his daughter’s killer in 2019, David was diagnosed with cancer and told it was not treatable.
The police shared the news that he died earlier this week in his hometown in England.
His passing comes after the tragic death of daughter Grace, who was killed in Auckland in December 2018.
Grace was 22 years old when her body was found in the Waitākere Ranges. In late 2019, a man was arrested and found guilty of her murder.
Detective Inspector Scott Beard, who worked closely with the Millane family during the investigation, shared his sympathies to the family.
“The Millane family had their lives turned upside down when David’s much loved and cherished daughter Grace was murdered while visiting New Zealand in December 2018,” he said.
“NZ Police worked closely with the Millane family as part of the investigation into Grace’s murder and provided victim support throughout the subsequent trial. Our thoughts and sympathies are with Gillian, Michael, Declan and the rest of their whanau.”
