"Torrential blood loss" caused the death of a woman who was stabbed 17 times by her husband, a coroner has ruled.
Balclutha freezing worker Lusi Aleni-Faamoe Ioane, 41, was killed on October 3 last year after being stabbed from behind multiple times.
Her husband, Timothy Aleni, also a freezing worker, confessed to police when he called them to the scene immediately after.
The couple had six children, but they were not there at the time.
In findings released today, Coroner David Crerar said her death would have been almost instant.
Evidence detailed in the report showed the relationship between the pair, who married in 1995, had begun to deteriorate by the time Lusi was killed, due to Aleni's suspicions his wife was cheating on him.
A fight between the two on October 3 ended violently when Aleni ''approached his wife in the bathroom of their shared property, and stabbed her neck and upper body a number of times with a knife''.
"The wounds have caused torrential blood-loss and death," Crerar said.
A pathologist's report showed she would have died "within seconds" of the first wound being inflicted.
Aleni was charged with his wife's murder but ruled unfit to stand trial by grounds of insanity in May this year.
The evidence showed he was being treated for hallucinations and hearing voices, although was not always compliant when taking his medication.
Police said when they arrived at the scene and asked Aleni why he killed her, he just said "what's done was done".
Crerar extended his sympathies to Lusi Aleni's children and wider family.
