Berta Cáceres knew her work was dangerous.
After winning a prestigious international prize for her environmental activism last year, she said indigenous leaders like her were frequent targets.
"In my organization alone," she told CNN en Español, "we have 10 people who've been killed with total impunity."
Nearly 10 months later, investigators found Cáceres shot dead inside the home where she lived in La Esperanza, Honduras, about 110 miles west of the country's capital of Tegucigalpa.
"The state of Honduras has been directly attacked by the death of Berta Cáceres," President Juan Orlando Hernández said in a national address.
"This is a crime against Honduras, a blow to the Honduran people.
It will not go unpunished."
But even as authorities vowed to investigate and apprehend whoever is responsible, activists pointed to the killing as a troubling sign that officials haven't done enough.
