The US military trained him. Then he helped murder Berta Cáceres

Castillo is certain to be remembered: earlier this year, the Honduran high court found him guilty as the joint perpetrator in the 2016 assassination of the indigenous activist Berta Cáceres, then one of Latin America’s most prominent environmental defenders.

Cáceres was killed by a team of hitmen after years of death threats linked to her opposition of the 22-megawatt Agua Zarca dam, approved by the government without permission from the local indigenous people.

Castillo was the president of the company building the dam and the court concluded that he had used his military training to stalk her for years, while secretly helping coordinate the assassination.

Some of that training came from West Point, where Castillo studied from 2000-2004.
