The family of adventurer Emma Kelty have paid tribute to their "determined sister" after she was robbed and murdered while kayaking alone in the Brazilian Amazon.
The 43-year-old former headteacher's three siblings said she was dearly loved and will be sorely missed.
The Londoner was last heard from a week ago just days after posting online about her fears of being robbed or murdered in a jungle area in Brazil's remote north used for drug trafficking.
Three people are in custody including a teenager who had confessed to carrying out the killing with six other people.
In the Foreign Office statement, Ms Kelty's brothers Piers and Giles and her sister Natasha said:
Emma Kelty was 42 days into a 4,000-mile trip from the Amazon's source in Peru, through Brazil using GPS, social media and blogging to let friends follow her progress.
Her last known location was around 150 miles west of the jungle city of Manaus, between the towns of Coari and Codajas.
