(Reuters) - A forensic exam carried out on human remains found in the Amazon rainforest confirmed on Friday that they belonged to British journalist Dom Phillips, Brazil's federal police said, adding that a search was underway for a man suspected of involvement in his killing.
Work is proceeding to determine the cause of death, police said in a statement.
The remains of a second person, believed to be that of indigenous expert Bruno Pereira, were still under analysis, a report by CNN Brasil said earlier on Friday.
Pereira and Phillips vanished on June 5 in the remote Javari Valley bordering Peru and Colombia. Earlier this week, police recovered human remains from a grave in the jungle where they were led by a fisherman, Amarildo da Costa Oliveira, who confessed to killing the two men.
Phillips, a freelance reporter who had written for the Guardian and the Washington Post, was doing research for a book on the trip with Pereira, a former head of isolated and recently contacted tribes at federal indigenous affairs agency Funai.
Police said their investigation suggested there were more individuals involved beyond Oliveira and that they were now looking for a man named Jeferson da Silva Lima.
He is the third suspect named by police after Oliveira and his brother, Oseney da Costa, who was taken into custody this week.
"There is an arrest warrant issued by the State Court of Atalaia do Norte against Jeferson da Silva Lima, aka 'Pelado da Dinha', who has not been located at this time," police said.
