She was a brilliant lawyer who taught young students how to prepare for mock trials. He was the beloved manager of a chocolate shop and cafe who was known for putting his staffers' needs first.
Both of their lives ended in a hail of bullets inside a Sydney cafe after a disturbed gunman took them hostage along with 15 others yesterday.
Katrina Dawson, a 38-year-old mother of three, and Tori Johnson, the 34-year-old manager of the Lindt Chocolat Cafe, where the 16-hour siege unfolded, were are being lauded for their courage after unconfirmed reports that they tried to save their fellow hostages.
Sydney's Catholic Archbishop Anthony Fisher said at a memorial service attended by hundreds of people at St Mary's Cathedral that Mr Johnson had reportedly brought the siege to a head by grabbing the shotgun wielded by hostage-taker Man Haron Monis.
Monis was killed as police stormed the café to end the siege.
"Apparently seeing an opportunity, Tori grabbed the gun. Tragically, it went off, killing him. But it triggered the response of police and eventual freedom for most of the hostages," Mr Fisher said.
"Reports have also emerged that Katrina Dawson was shielding her pregnant friend from gunfire. These heroes were willing to lay down their lives so others might live."
New South Wales Deputy Police Commissioner Catherine Burn declined to comment on any individual's actions, saying what transpired in the cafe remained under investigation.
"This will all come out in time, no doubt," she said. "Can I just say, I think every single one of those hostages, every single one of those victims, acted courageously."
Ms Dawson was the mother of three young children - Chloe, Sasha and Oliver - and a highly respected commercial lawyer.
She was remembered as "one of our best and brightest" by New South Wales Bar Association president Jane Needham.
Andrew Powell, head of the Ascham School, which she attended in her youth, said she was a well-respected and giving woman who excelled at her studies. Her daughter Chloe is a student at the school and Sasha will be attending next year.
Ms Dawson was the school's debating captain and played hockey and basketball. After she became a lawyer, she helped teach senior students at her former school how to prepare for mock trials.
Mr Johnson was remembered as a selfless man who put others first.
"By nature he was a perfectionist and he had a genuine passion for the hospitality industry and people," Lindt Australia CEO Steve Loane said in a statement. "His loss is absolutely tragic."
His parents issued a brief statement, thanking the public for its support.
"We are so proud of our beautiful boy Tori, gone from this earth but forever in our memories as the most amazing life partner, son and brother we could ever wish for," they said.
