About 90% of the inmates in the maximum-security prison are locked in their cells for 19 hours a day, said Walker, the legal advocate.
"It's pretty grim," Walker said.
The cells
Souza has slightly larger cells than most other Massachusetts prisons, but not by much, Walker said.
Even so, the cells are stark, small rooms of painted cinder-block walls with metal fixtures: a bunk mounted to the wall, a toilet and sink combination, a small writing shelf attached to the wall, and a nearby small stool affixed to the floor, Walker said.
There's also a shelf for a small television, which must have a clear back for easy inspection, Walker said.
With the exception of the TV, which inmates can buy for under $200, all furnishings are metal and bolted down to keep inmates from throwing them, she said.
