SAO PAULO (Reuters). A forensic analysis of remains in Brazil’s Amazon (NASDAQ) rainforest revealed that the remains belonged to Dom Phillips (British journalist). Brazil’s federal police added that a probe was ongoing for a possible suspect in Phillips’ murder.

According to police, work is underway to establish the cause of death.

CNN Brasil reported earlier Friday that the remains of another person, thought to be Bruno Pereira, are still being analyzed.

Pereira, Phillips and their bodies were found in the Javari Valley near Peru and Colombia on June 5. Amarildo da Silva Oliveira, a fishing man, confessed that the two men had been killed. Police found human remains in an area of the jungle earlier this week.

Phillips was a freelance journalist who previously wrote for the Guardian, Washington Post and other publications. Pereira, an ex-head of recently contacted tribals in federal indigenous affairs agency Funai, was conducting research on Phillips’ trip for a book.

According to police, their investigations suggested that there may have been more people involved than Oliveira. They are now searching for Jeferson Da Silva Lima.

This is Oseney Da Costa’s third suspect, after Oliveira, his brother and Oseney da. He was arrested this week.

Police stated that a warrant was issued by the State Court of Atalaia do Norte for Jeferson da Silva Lima (aka “Pelado da Dinha”), but that he has yet to be located.

The investigations show that the murderers acted on their own, without any bosses or organized criminals behind them.

Univaja, a local indigenous group, played an important role in the search. It said that Phillips and Pereira crossed paths with Univaja who was a strong criminal organization trying to hide its tracks throughout the investigation.

The Javari Valley had been the scene of organized crime, according to it.

INA, a union that represents workers at Funai shares this view.

It added that “We all know violence in Javari Valley is connected to a large chain of organised crime,” in another statement.

The police stated that they still searched for Phillips and Pereira’s boat when they disappeared.

Ned Price, spokesperson for the U.S. State Department on Friday demanded “accountability” and justice. He stated that Phillips was murdered because he supported conservation efforts for native peoples.

Price expressed condolences on behalf of Bruno Pereira and Dom Phillips’ families via Twitter (NYSE:).
