"We are broken-hearted to share this news with our friends and family: Yesterday morning, while on a volunteer mission to protect wildlife in South Africa, Kate Chappell was involved in a tragic and fatal accident. Katie was a brilliant, kind, adventurous and high-spirited woman. Her energy and passion could not be contained by mere continents or oceans. She was very much loved and shared her love for life with those she met.
"We cannot thank everyone enough for the kind words and support. It means the world to us during this difficult time."
Katherine was also a keen wildlife conservationist and raised money to protect South African animals
