SEMI Cakaunibula, a policeman of 14 years at the Sabeto Community Post, said he was not blaming anyone for the death of his eldest son Ratu Tevita Mateitoga.
The 20-year-old new recruit was found dead in the Police Special Response Unit canteen freezer on Tuesday.
"I just want the law to take its course and will await the outcome of the investigations. But I also want to know what happened to him," he calmly said.
Mr Cakaunibula said his son had returned to the village on Thursday after spending six months at the police academy attending recruitment training.
"He came to see his youngest brother, Aisea, who is two months old.
"It was the first time for Tevita to see him and little did we know that it would be the last."
Mr Cakaunibula said his son was a quiet and humble person by nature and well-liked in the village.
He added members of the special response unit had visited him at the village to inform him of his son's death.
Ratu Tevita was last seen accompanied by two colleagues over the weekend.
Police spokeswoman Ana Naisoro said investigations into the incident were continuing
Ratu Tevita, named after Na Momo Levu Na Tui Sabeto, will be laid to rest on Wednesday.
