A Queensland coroner has found a man repeatedly tasered by police during a domestic dispute did not die as a direct result of the stun gun being used.
Deputy State Coroner Christine Clements found Antonio Carmelo Galeano, 39, died as a result of psychosis induced by amphetamine toxicity.
"I note there is no evidence the application of the Taser directly caused Mr Galeano's death," she said, handing down her findings in Brisbane on Wednesday.
"There is no evidence the application of capsicum spray caused or contributed to Mr Galeano's death."
Ms Clements found there was no reason to refer any of the three police officers at the scene for criminal or disciplinary action.
The coronial inquest into Mr Galeano's death on June 12, 2009, at his girlfriend's unit block in Brandon, a small town south of Townsville in north Queensland, was held earlier this year.
When two police officers arrived at 2.50am they found Galeano naked, having destroyed much of the unit on a drug-induced rampage.
The inquest heard Mr Galeano was not in a rational state, and the two officers used various methods to subdue him.
During the struggle, Senior Constable Craig Myles discharged his Taser 28 times.
After Mr Galeano was finally handcuffed, he went into cardiac arrest and could not be revived.
As Mr Galeano died in police custody there was a mandatory coronial investigation and an inquest.
Ms Clements said while her findings of fact clearly showed the Taser had been discharged 28 times, it was not clear how many times the device had been consciously deployed.
Ms Clements said Constable Myles' decision to use the Taser was against police guidelines, but the circumstances had to be taken into account.
"The officers were faced with an extremely agitated and irrational man who was unresponsive to any communication from his friends or police," she said.
Ms Clements said police were totally unprepared for the severity of Mr Galeano's psychotic state induced by amphetamines.
She added the use of the Taser, with the benefit of hindsight, might have been hasty but to a large extent was forced by circumstances.
In her 105-page judgment, Ms Clements recommended cameras be installed on all Tasers and said a joint taskforce of police and ambulance officers was needed to address the problems of such drug-induced incidents.
She also recommended police and family be told when someone had been treated at hospital for drug-related problems.
She noted Mr Galeano had been treated two days earlier at Ayr and Townsville hospitals for amphetamine-related psychosis but had been released because he had no mental illness.
Outside court, the Queensland Police Union president Ian Leavers praised the findings as well-balanced.
He said the drug problem was a statewide one and police had been pushing for body cameras to record incidents such as the one involving Mr Galeano.
The two officers first on the scene had left the police force because of stress.
Mr Galeano's family described the coroner's findings as a disgrace.
The family spent 90 minutes reading Ms Clements' findings before coming outside the court to discuss them with the media.
"We have been living a nightmare for three and a half years and the coroner has continued that nightmare today," said Giovanna Tama, Mr Galeano's older sister.
"It is a disgrace - that is all I have to say."
She said the family believed the police officers should have been charged over her brother's death.
