Federal police said Friday that some of the human remains found deep in Brazil's Amazon rainforest have been identified as belonging to British journalist Dom Phillips, who went missing almost two weeks ago along with a Brazilian Indigenous expert in a case that drew worldwide attention.

Additional remains found at the site near the city of Atalaia do Norte have not yet been identified but are expected to belong to Indigenous expert Bruno Pereira, 41.

The pair was last seen June 5 on their boat on the Itaquai river, near the entrance of the Javari Valley Indigenous Territory, which borders Peru and Colombia.

"The confirmation [of Phillips' remains] was made based on dental examinations and anthropological forensics," police said in a statement.

"Work is ongoing for a complete identification of the remains so we can determine the cause of death, and also the dynamics of the crime and the hiding of the bodies."

The remains were found Wednesday near the city of Atalaia do Norte after fisherman Amarildo da Costa de Oliveira, 41, nicknamed Pelado, confessed that he had killed Phillips, 57, and Pereira, and led police to the site were the remains were found.

He told officers he used a firearm to commit the crime.

Police also arrested Pelado's brother, fisherman Oseney da Costa de Oliveira.

The remains had arrived in the capital city of Brasilia on Thursday for forensics to work.

Bolsonaro under fire

The area where Phillips and Pereira went missing has seen violent conflicts between fishermen, poachers, and government agents.

Federal police said others may have participated in the crime but that organized criminal groups did not appear to be involved.

UNIVAJA, the local Indigenous association for whom Pereira was working, criticized that conclusion.

It said in a statement the investigation had not considered the existence of a criminal organization financing illegal fishing and poaching in the Javari Valley Indigenous Territory.

"That was why Bruno Pereira became one of the main targets of this criminal group, as well as other UNIVAJA members who received death threats," the statement said.

Brazilian President Jair Bolsonaro, a frequent critic of journalists and Indigenous experts, has drawn criticism that the government didn't get involved fast enough.

Earlier, he criticized Phillips in an interview, saying — without evidence — that locals in the area where he went missing didn't like him and that he should have been more careful in the region.

His main adversary in October's election, former president Luiz Inacio Lula da Silva, said in a statement that the killings "are directly related to the dismantling of public policies of protection to Indigenous peoples.

"It is also related to the current administration's stimulus to violence," said da Silva, who leads in opinion polls.

'Fish mafia'

The efforts to find the pair were started by Indigenous peoples in the region.

Indigenous people who were with Pereira and Phillips have said that Pelado brandished a rifle at them on the day before the pair disappeared.

Official search teams concentrated their efforts around a spot in the Itaquai river where a tarp from the boat used by the missing men was found.

Authorities began scouring the area and discovered a backpack, laptop and other personal belongings submerged underwater Sunday.

Authorities have said a main line of the police investigation into the disappearances has pointed to an international network that pays poor fishermen to fish illegally in the Javari Valley reserve, which is Brazil's second-largest Indigenous territory.

Pereira, who previously led the local bureau of the federal Indigenous agency, known as FUNAI, took part in several operations against illegal fishing.

In such operations, as a rule, the fishing gear is seized or destroyed, while the fishermen are fined and briefly detained.

Only the Indigenous can legally fish in their territories.

While some police, the mayor and others in the region link the pair's disappearances to the "fish mafia," federal police have not ruled out other lines of investigation, such as drug trafficking.

LISTEN | Land defenders are coming under attack, says Global Witness: 
Brazilian police now say a man has confessed to the murder of British reporter Dom Phillips and Brazilian land rights activist Bruno Pereira, both of whom failed to return from an investigative trip into a remote part of the Amazon. Global Witness is a not-for-profit group that has been tracking the killings of land defenders for the past 10 years. Marina Comandulli, a campaigner for Global Witness' land and environmental defenders team, says the attacks and killings are happening regularly all over the world and often go unreported.

The case has put a global magnifying glass on violence in the Amazon.

Earlier on Friday, U.S. State Department spokesman Ned Price said Phillips and Pereira were "murdered for supporting conservation of the rainforest and native peoples there."

"We call for accountability and justice — we must collectively strengthen efforts to protect environmental defenders and journalists," Price said.

Protests calling for justice for Phillips and Pereira are scheduled to take place in several Brazilian cities over the weekend.
