You may want to read Chapter 7 of If Nuns Ruled the World by Jo Piazza[1]. Sister Dianna Ortiz was kidnapped in Guatemala in the late 1980s and ended up in a CIA torture prison. A case of mistaken identity and lots of cover-ups ensued, but she lived to tell the tale[2]. She sadly passed away last year, RIP.
