The 35-year-old correspondent for Radio Globo and Azteca TV was shot twice and fatally injured on Sunday and died in hospital on Monday.
Media reports said that gunmen on a motorcycle opened fire multiple times on Almendares when he visited a store in the region of Comayagua, north of the capital Tegucigalpa. He was taken to hospital with multiple gunshot wounds from which he died a day later.
The journalist was known for his publications denouncing corruption in Honduras politics and the activities of organised crime groups in the country.
Almendares had reportedly received death threats and filed complaints with the police and the country’s National Protection System, according to rights groups quoted by AFP.
