A Queensland man has been sent to jail for life for setting fire to his ex-girlfriend's house in a jealous rage, killing two people and seriously injuring his former lover.
Craig Anthony Leonard, 30, was given a minimum non-parole period of 20 years in the Queensland Supreme Court in Brisbane on Tuesday.
Leonard pleaded guilty to murdering Nicholas David Spohn, 23, and Jennifer Anne Bachmann, 43, in April 2011.
He also pleaded guilty to causing grievous bodily harm to his ex-girlfriend Rina Linda Mayall, then 24.
The court heard Leonard set fire to Ms Mayall's Gold Coast house while she was in bed with her new boyfriend in a jealous fit fuelled by drink and drugs.
Months earlier Ms Mayall ended her eight-month relationship with Leonard and rebuffed attempts to reconcile, Crown Prosecutor Michael Byrne SC said.
After drinking heavily and injecting amphetamines, Leonard drove to the Beachmere house on the night of April 17, and used petrol to set a mattress alight under the home.
The house caught fire and Ms Bachmann and Mr Spohn, who were asleep, died of smoke inhalation.
Ms Mayall jumped from a verandah and broke her back.
Mr Byrne told the court Leonard later told police he just wanted to "put the wind up" his ex-girlfriend and "f*** her up financially".
In a statement, Mr Spohn's mother, Erika Varga, said their family had been robbed of a life with their son.
"We will never see him, hold him, hug him and tell him how much we love him," it read.
Ms Bachmann's sister, who cannot be named, told the court through tears how her sister was so badly burned DNA tests were needed to identify her.
In sentencing, Justice James Douglas said there was evidence to suggest Leonard's crime was a stupid act brought on by intoxication but that didn't detract from its seriousness.
"To describe it as stupid or senseless is to severely understate the effect of what you have done," he said.
