A man who stabbed Giovanni Focarelli has been sentenced to at least six years in jail for what a judge described as a brazen and inexplicable attack.
The South Australian Supreme Court heard Focarelli was stabbed in the stomach and chest after being called over to a car in Hindley Street in Adelaide, in May 2010.
Hameed Ullah Dastagir, 26, was found guilty of an aggravated charge of causing serious harm with intent, but acquitted of attempted murder.
Justice Kevin Nicholson said CCTV vision showed a black Nissan Skyline pull up and wait for traffic in front of it to clear, ready for a quick getaway.
"Giovanni Focarelli is seen to approach the car and almost immediately, within one or two seconds, he is seen to reel back holding his stomach and stumbling back into the tattoo parlour," he said.
Justice Nicholson said the wound to Focarelli's stomach perforated his colon and another in his chest narrowly missed his heart.
"Mr Dastagir, you are very fortunate Mr Focarelli did not die. Had he done, a conviction for murder with a mandatory minimum non-parole period of 20 years would've been almost inevitable.
"In 2012 he was shot and killed in an incident apparently unrelated to this incident."
Justice Nicholson said Focarelli did not co-operate with police.
"At no time prior to his death was Giovanni Focarelli prepared to co-operate with police in their investigation of the charges brought against you," he told Dastagir.
"There was no victim impact statement from his or any member of his family. There was no evidence of any disagreement or any matter that might suggest a reason for your conduct.
"You did not give evidence in the trial ... you have maintained your innocence throughout and still do."
Justice Nicholson said the attack was clearly premeditated and executed in cold blood.
He sentenced Dastagir to 10 years and four months in jail with a non-parole period of six years.
The judge said Dastagir's strong family support and good behaviour in prison were indicators of his prospects of rehabilitation.
"While I am prepared to show some leniency, this must be seen in the context of a very serious example of a very serious offence that involved conduct that was life-threatening, premeditated, brazen and unexplained," he said.
Justice Nicholson gave eight months' credit for the time Dastagir had spent on home detention bail and a week he spent in custody after his arrest.
He backdated the sentence to last October when Dastagir's bail was revoked.
Outside court, Dastagir's family cried as they comforted each other.
