"My name is Freddy Guanto Pantaluka Saca. I am here for killing people. I have been here for 25 years - I will never be free, the judge forgot about me!" this man says, smelling strongly of chicha (a local alcoholic drink)
In a mix of Quechua and Spanish, Freddy shouts something about suffering.
Few of the inmates here are convicted killers - 80% of them are here for drug-related offences. Only about 25% of all prisoners are actually serving a sentence - the rest are awaiting trial.
