La Sabaneta Prison
The reason why this Venezuelan prison made it on the list is because of how poorly maintained it is. The truth is that this place was supposed to just house 15,000 inmates. Apparently, 25,000 of them are currently there. This made the place even more difficult to survive. Violent incidents happen all the time. There was even a gun battle in 1994 that resulted to the deaths of 108 prisoners. Since 1995, 196 more died and over 600 were wounded due to constant violence. Imagine have only 1 prison guard for over 150 inmates. This makes the place extremely dangerous.
