Rodrigo Rosenberg Marzano (November 28, 1960 – May 10, 2009) was a Guatemalan attorney. Before his death, Rosenberg recorded a video message saying if he were murdered, Álvaro Colom Caballeros, President of Guatemala, Gustavo Alejos, Sandra Torres de Colom, and Gregorio Valdés would have been directly responsible. His subsequent killing caused a national uproar. After an investigation by a United Nations commission, officials declared that Rosenberg had arranged his own death and had contacted cousins of his former wife, Francisco José Ramón Valdés Paiz and José Estuardo Valdés Paiz, to hire a hitman.
Carlos Castresana, the head of the CICIG, the United Nations Commission Against Impunity in Guatemala, who headed the investigation at that time, emphasized that this was a provisional hypothesis. The cousins accused were sent to jail for complicity in a hearing behind closed doors, where they remained without a trial for more than two years.
Further investigation by the same commission has turned up links between the killers that shot Rosenberg and those of Marjorie and Khalil Musa.
Two of the killers who took part in both killings and had originally changed their testimony to accuse the Valdés Paiz brothers have accused the Public Ministry of Guatemala and the United Nations Commission Against Impunity in Guatemala of pressuring them to accuse the Valdés Paiz brothers.
Rosenberg's recorded video message claiming that President Colom would be responsible if he were killed
Rosenberg was shot dead on May 10, 2009, while cycling in Guatemala City. He was approached by an assassin who came down a grass bank and shot him in the back. The killer ran around Rosenberg's left side and fired another bullet down his cheek, which exited from his neck, and another, which did not exit, into his neck. The killer then knelt on his right side and placed the gun under Rosenberg's jaw, firing another bullet that tore through Rosenberg's eye and went out his left temple. Finally, the murderer moved the gun to Rosenberg's forehead as it faced away from him and fired a final shot, which lodged in his brain.
