Extractive Reserve is a protected area where resident families should make their living off natural products extracted from the forest. Extractives activity keeps the forest integrity.
According to her son, Tuian Santiago Cerqueira, Rosane had received death threats.
"Unfortunately, today there is a feeling of total insecurity, because of the State's absence in prosecuting these crimes. We were with her at Christmas, and everyone realised that she was worried and now we know that she had denounced three death threats” her son Tuian said to Rádio Brasil Atual.
Rosane Santiago Silveira lived 18 years in Nova Viçosa, struggling to create an association to protect the island of Barra Velha - an area of extractive environmental reserve, and she she was member of the Cassurubá Extractivist Reserve Council.
"The land where she lived was reserved to the extractive work, and she struggled to prevent the advancing of the eucalyptus plantations," explained Tuian.
According to her son, Rose was found dead in her house, with hands and feet tied and wounded, a cloth around the neck and stab wounds and gunshots at the head. "I saw at the body, it was a torture scene, it was stabbed, tied with signs of fighting, and a shot from behind," he said.
According to Tuian, the death of Rosane created a climate of terror in the city. "Everybody is scared, my mother was cheerful, she had a good relationship with people, despite being strong in the fights, she was always friendly and kind to the people" he said.
Rose joins dozens of environmental activists murdered each year in Brazil. In 2016 and 2017, the country ranked the number of murders of environmental activists, according to British NGO Global Witness, which reported 57 executions in 2017.
