Kinnear explained that Karina, who was paralysed from the waist down and suffered severe brain damage at birth, tested positive for coronavirus early last week. The disease "quickly attacked her stomach, her lungs and her kidneys".
He continued: "Her lung capacity was so diminished that we knew, given the reports of its effects, that it was likely to prove incredibly dangerous for her. Her conditions weren't just 'underlying', they were life-defining, for her and for us, even if she remained unaware of their severity. But Karina had defied predictions her entire life."
He then paid tribute to her bravery and zest for life.
"Karina was ebullient, brave and wry, with a passion for noise, laughter, family and chaos.
"And those that engaged with her, knew her, loved her, were rewarded beyond their imagination by her friendship and trust. They grew to learn, inexorably and unalterably, that our spirits exist far more tangibly than our abilities. What a lesson. What an inspiration."
