Letters recently sent from two female inmates at the Arizona State Prison Complex-Perryville describe their growing desperation as their basic hygienic supplies disappeared.

"I ran out on Saturday 9/30," one wrote, "and although I continually asked for [toilet paper], was told they were out. They did have pads that I used as [toilet paper] until Monday 10/1 when they ran out. I then had to use a wash rag until Wed morn."

Aric Toler isn't exactly sure what to call himself.

"Digital researcher, digital investigator, digital something probably works," Toler says.

Toler, 30, is part of an Internet research organization known as Bellingcat. Formed in 2014, the group first got attention for its meticulous documentation of the ongoing conflict in Ukraine. Toler used posts to Russia's equivalent of Facebook, VK, to track Russian soldiers as they slipped in and out of eastern Ukraine — where they covertly aided local rebels.
