Three people were arrested Monday in connection with the 2011 killing here of Argentine singer Facundo Cabral, Guatemalan police said.
Amparo Antonia Revolorio Figueroa, 41; Oscar Oswaldo Rodriguez Escobar, 38; and Eli Adonais Osorio del Cid, 33, were apprehended in the southern province of Escuintla.
The three are suspected of belonging to the band of killers who murdered Cabral on July 9, 2011.
The 74-year-old folk music icon was fatally shot while being driven to La Aurora International Airport the day after he performed in Guatemala City.
Guatemalan authorities quickly concluded that the man at the wheel - Nicaraguan promoter Henry Fariña - was the real target of the attack.
Fariña, who was wounded in the attempted hit, was subsequently convicted in his homeland on drug and money-laundering charges and is serving a 30-year prison sentence.
Investigators determined that the attack was ordered by Costa Rican Alejandro Jimenez, who was arrested in Colombia in March 2012 and taken to Guatemala.
Jimenez is being held in Guatemala for the crimes of murder, attempted murder, illicit association and covering up a crime.
Already under arrest as the perpetrators of the killing of the Argentine singer were Elgin Enrique Vargas Hernandez, Wilfred Allan Stockes Arnold, Juan Hernandez Sanchez and Audelino Garcia Lima.
So far, the Guatemalan judicial system has not set a date for the trial of those responsible for Cabral’s death.
