Rozelle shopkeeper Adeel Khan has been sentenced to a minimum of 30 years in jail for the manslaughter of three people who died in a blaze.
Khan always maintained his innocence, but evidence showed he bought 38L of petrol that fueled a fire in his failing store. It engulfed multiple apartments above, killing two adults and a baby.
The court heard Khan was $400,000 in debt at the time of the fire.
The fire consumed the building on September 4, 2014 as multiple containers of petrol exploded in Khan's shop, killing Chris Noble in the apartment above and injuring two roommates.
The court heard Noble was trapped in his room and sent a text message to his mother during the inferno that said "I love you".
The fire then spread to the O'Brien home that burned down with mother Bianka O'Brien and her infant son, Jude inside.
He was found guilty of three counts of manslaughter and two counts of grievous bodily harm.
As he was sentenced in New South Wales Supreme Court, Justice Elizabeth Fullerton said his lack of remorse was troubling.
"That he did not intend to cause a massive explosion does nothing to diminish what I consider offending of the most serious crime," Fullerton said.
