She was always campaigning for her family and her children so they could live in peace when they grow up.” According to the virtual magazine Generación Paz, the Kokonuko community began a process of recovery of Mother Earth a few years ago in the Aguas Tibias property of Diego Angulo, a businessman from the City of Popayán (the Capital of the Colombian department of Cauca), where a tourist center and thermal water resort were located.
Efigenia went to the disputed property of Aguas Tibias to support and document a confrontation of her community with ESMAD on Sunday, October 8, 2017.
As documented by FLIP, members of the Indigenous Guard requested an ambulance to pick up Efigenia, but the driver told them that he was not allowed to enter the place.
The commander of the Police in the southwest of the country, William Salamanca, suggested that the Kokonuko community itself would have been responsible for the type of gunshot.
Irina Bokova, that time the Director General of the United Nations Educational, Scientific and Cultural Organization (UNESCO), urgently asked the Colombian government investigate the murder of journalist.
