Jesús Tecú Osorio (born 1971 in Río Negro, Baja Verapaz) is a Guatemalan social activist, worker for human rights, and advocate for the Achi Maya.
In 1982, much of the population of Río Negro was murdered; Tecú survived, but witnessed the deaths of most of his immediate family members, including his two year old little brother, who was torn from his arms and thrown into a ravine.
[1] He spent two years as a household slave to one of the perpetrators before being remanded into the custody of his older sister, who had also survived the massacres.
In 1993, Tecú began legal proceedings to have the mass grave of Río Negro exhumed; this led directly to the prosecution of three of the men responsible for the massacre and, in 1998, to their being sentenced to death for crimes against humanity (in 1999, their sentences were commuted to 60 years in prison).
He has written his memoirs – these have been translated into English as The Massacres of Rio Negro – and gone on speaking tours throughout Canada, Europe, and the USA.
