When Jared Remy casually raised a cuffed hand to his face while pleading guilty to murder earlier this week, he flashed what appeared to be a neo-Nazi jailhouse tattoo on his right hand.

Remy’s forearms are covered with elaborately detailed, richly colored tattoos predating his time behind bars, including a grim reaper and a busty nude in fishnet stockings. But as photos of Remy circulated online, it was a small, crudely etched symbol near his thumb and forefinger that stood out to those familiar with prison ink: “88.”
