It was an attack that sent shockwaves through a country long considered a pioneer in LGBTQ rights. In the early hours of May 6, four lesbian women were set on fire in Argentina. Only one of them survived. It happened at a boarding house in the Barracas neighborhood of Buenos Aires, where Pamela Fabiana Cobas, Mercedes Roxana Figueroa, Andrea Amarante and Sofía Castro Riglo were sharing a room. Witnesses say a man broke in and threw an incendiary device that set the women on fire. Pamela died soon after. Her partner Roxana died days later of organ failure. Andrea died on May 12 in a hospital.
