My 1st ex was incarcerated in the San Juan unit, now known as the Lumley Unit. It's called Lumley after the guard who was murdered there by an inmate. I spent 2 years visiting him twice a week before I dropped divorce proceedings on him.
It went from an all male minimum/medium security prison to an all female medium/maximum prison.
Anyone who says that place is better than Estrella has never been there. I have seen and been in the cells, they had an "open house" during visitation at one point. This was in 1983. The facility opened in 1981. It went from what appeared to be an open college campus to a gladiator school very quickly.
Myself and other visitors watched an inmate rape his wife on a picnic table one evening as the guards ignored it. We could leave, the guards had to deal with these inmates every day, the last thing they were going to do is get between an inmate and a "civilian" and have a bull's eye on their backs. I was assaulted by my ex in the visitation room......the guard operating the sallyport got the door open in time before my ex literally beat the crap out of me. No one stepped in.
Prison is an equal opportunity environment. The women are just as violent and deadly as the men. They have their gangs, their drugs, shake downs, hit lists, their food chain. "Dog eat dog".
Estrella is "summer camp" compared to Perryville. I'd say ADOC Florence is far better, and they still use the old cell blocks erected back in the early 1900's along with the newer facilities. (been there also, as a visitor)
