Authorities have recovered the remains of 14 bodies at a shuttered prison in central Venezuela, reviving questions about human rights violations in the nation's penitentiaries.

Excavators discovered the bones at the General Penitentiary of Venezuela in Guarico on March 9. Some 5,000 prisoners at the prison were transferred to other facilities in October.

Human rights activists say the bodies may belong to prisoners reported missing several months ago. A group of experts is examining the remains to determine the cause of the deaths.

Venezuela has an estimated 50,000 inmates in 30 prisons, where overcrowding and violence are common.
