"He mouthed to me, 'Dwina, I want to go home.' Instead, he is now on his last journey. But at least I know he is safe. I am proud of Robin's life, what he has achieved and the inspiration and the happiness he gave so many people," Dwina said.
"I am devastated to have lost my best friend, my husband, my brother. Robin was everything to me. I shall miss him for the rest of my life," she added.
