The mother of a 13-year-old boy killed in a Sydney house fire more than 20 years ago has vowed to never stop searching for those responsible for the blaze as a police reward for fresh information on the case is lifted to $1 million.
Arthur Haines was staying at a friend's house in Waterloo, in Sydney's inner south, on April 9, 1998, when it was allegedly deliberately set alight.
The 13-year-old became trapped on the top floor of the burning home and managed to escape the fire but suffered severe burns. He died in hospital almost three months later.
No one has ever been charged over the alleged fatal arson.
The case was referred in January for re-investigation and on Monday, the anniversary of Arthur's death, the reward for information on the case was lifted from $100,000 to $1 million.
His mother Julie Szabo said she would never give up in the search for those responsible.
"My son would have been 36 this year and not a day goes by where I don't think of him and wish he were here," Ms Szabo said in a statement on Monday.
"He was a kind boy who was respectful to his elders and he was taken from us too soon.
"I thank the police for never giving up on my boy and I hope the reward encourages those who know what happened to come forward."
NSW Police Detective Superintendent Daniel Doherty on Monday said community help would be vital to the investigation and hoped the reward would encourage people to come forward.
"We are keen to speak to people who lived in the area at the time as someone must know something about how this tragic incident occurred," Det Supt Doherty said in a statement.
The reward is available for information which leads to the arrest and conviction of the person or people responsible for Arthur's death.
"This boy's family have been suffering for years and deserve justice and closure at the very least," NSW Police Minister David Elliott said in a statement on Monday.
