Iboy Osorio and Chen Iboy were the wife and son, respectively, of Rio Negro survivor and human rights activist Carlos Chen (forefront with hat), both killed along 175 other women and children during the Pak'oxom masacre on March 13, 1982, by the Guatemalan Army and Civil Patrolmen of neighboring Xococ. The community of Pacux, in the outskirts of Rabinal, is where the former Achi Mayan residents of Rio Negro were resettled after the destruction and flooding of their village. Carlos Chen, Rio Negro survivor, has led the search for reparations via his organization COCAHICH (Coordinating Committee of Communities Affected by the Construction of the Chixoy Dam) since 2004.
