Brazil's federal police said they had a "strong conviction" a gang leader known a "Colombia" ordered the brutal murders of British journalist Dom Phillips and Indigenous expert Bruno Pereira, killed in the Amazon rainforest last June.
The gang leader, Ruben Dario da Silva Villar, is already in police detention after being charged along with three other people for double homicide and concealment of corpses.
Villar allegedly planned the killings because Pereira, a former head of isolated and recently contacted tribes at federal Indigenous affairs agency Funai, was carrying out inspections of illegal fishing operations, causing major losses to Villar's criminal group, the police said in a statement Monday.
According to police, Villar was the leader and key financier of an armed criminal group engaged in illegal fishing in the Amazon.
Villar, a Colombian national, has also been charged for use of a false document after allegedly using a fake birth certificate to work in Brazil, as well as using a fake Peruvian identity.
Pereira and Phillips vanished last year on a trip to the remote Javari Valley on the border between Peru and Colombia. Days later, a fisherman who had confronted Indigenous patrols in the area confessed to killing them.
Phillips, a freelance reporter who had written for outlets including The Guardian and The Washington Post, was on a trip with Pereira doing research for a book.
