During his time behind bars Raymund lived on a diet of dried fish which he claims left him on the edge of starvation. Now a Doctor of Criminal Justice having studied at Michigan State University, Dr Narag is now an assistant professor at the Southern Illinois University. He returned to his former cage to study how Filipino prisons can be reformed. Talking of his life behind bars, he has said: “I saw firsthand the intricacies of managing a crowded, underfunded, undermanned prison institution.” Dr Narang has said the food is not only inadequate but inmates can often find rusty nails and cockroaches leaving it inedible. It is also served at irregular intervals at odd times of the day, making it impossible for them to gain any sense of routine to cope with the squalor.

Some of the men are even said to have suffered strokes as a result of sleeping in a squatted position. Dr Narag said: “Inmates are prone to contagious diseases because of the poor living conditions in their cells. “They sleep in overcrowded, poorly ventilated cells. The supply of potable water is very limited. Food rations have inadequate nutritional content. Sick and healthy inmates are grouped in the same cells.” “Every month in Quezon City Jail, around two to five inmates die of illness.” The crushing boredom and lack of sleep also leads to inmates developing depression and other mental illnesses. Dr Narag said his seven years of hell in Quezon City made him determined to talk about the horrors he had witnessed behind bars. He charted his experience of doing time in a book titled “Freedom and death inside the City Jail”.
