The minister who supervises the prisons blamed overcrowding for two murders that took place at La Refoma in Alajuela this week.
The minister is Cecilia Sánchez of Justicia y Paz. She said that over the last five years there have been just 29 murders inside prisons. She said this amount was low considering the number of inmates.
She said that the 13 prison centers house 13,243 inmates with capacities for just 9,130.
As a result of the violence some of the inmates will be relocated, officials said. In addition there are more shakedowns of the prisons where weapons and other prohibited items turn up.
