In Brazil, blood has been found in a boat belonging to a suspect in the disappearance of British journalist Dom Phillips and the Brazilian researcher Bruno Araújo Pereira. Investigators say they’re sampling the blood to see if it came from one or both of the two men. The pair were reported missing on Sunday while working on a book project about conservation efforts in a remote part of the Amazon that has become a haven for illegal mining, fishing and international drug trafficking. Dom Phillips’s wife Alessandra Sampaio appealed in an emotional video for Brazilian authorities to intensify search efforts.

Alessandra Sampaio: “Why is that happening? I just don’t want him and Bruno to suffer. There in the jungle, there is a lot of cruelty. I’m heartbroken.”
