General Ernesto PĂ©rez commands the 321st Caribe Brigade. In June 2019, according to Venezuelan media outlets, the authorities arrested eight soldiers for allegedly plotting against the government, including plans to detain PĂ©rez, among others.
The general, who was born in 1971, is listed as treasurer for Cooperativa Madariaga 11, a company that is listed as providing travel, food, accommodation, and entertainment services. However, the address listed for its office is actually a metalworks shop.
