An Auckland family is demanding answers from the Samoan Government five years after their son and brother died while being held at Tafai-Ngata prison near Apia.
Hans Dalton suffered from a mental illness and was found dead upside down in a water drum in 2012.
Time hasn't healed the pain for Hans Dalton's family. Five years on they've had no closure or answers.
"We feel there is a lot of unresolved issues and the people who did this to Hans have not been held to account," Mr Dalton's sister, Natasha Dalton, told 1 NEWS.
"So truth and justice has not been upheld in Hans' case."
Hans Dalton hadn't committed any crime, but he'd lost his medication during a cyclone while on holiday in Samoa.
After suffering an episode, officials put him in a prison cell supposedly for his own safety. Instead he was killed there.
"It's about that bigger picture of inadequate services. Services that are designed to be a resource to help and support people obviously failed very badly," Mr Dalton's mother Christine Wilson said.
Samoan Police first said Mr Dalton committed suicide, but later arrested a prisoner for murder, who was then cleared.
The New Zealand coroner's office has been trying to get basic information from Samoa for the last three years, but to no avail.
The Daltons are also suing the Samoan Government which is pushing for mediation.
The family wants the truth to come out, in the hope it will prevent future deaths.
