Cruz Castillo, who was arrested, will remain in custody pending final repatriation. The Prosecutor General identified him as a person involved in the plot to kill Uribe.
“An investigation conducted in Colombia indicates that this attack was carried out by an organized criminal group involving multiple actors,” the statement said.
“Evidence has emerged that Cruz Castillo may have been involved in the logistical aspects of the attack.”
The prosecutor general said Castillo entered Argentina illegally and had previously been arrested in connection with a robbery case. They attributed his recent arrest to his cooperation with Colombian judicial authorities, who had issued an international alert about his arrest.
Uribe, a conservative senator from Colombia. He was shot in the head during a campaign event in the capital Bogota last June. He died two months later in August after undergoing multiple surgeries. He was 38 years old.
The shooting was met with shock and widespread condemnation. Uribe’s death was particularly symbolic.
His mother, prominent journalist Diana Turbay, died in a cartel-related kidnapping in 1991, and her story was immortalized in the nonfiction book News of a Kidnapping by Nobel Prize winner Gabriel Garcia Marquez.
Colombian prosecutors have charged a local criminal gang with organizing Uribe’s killing, and several members have been arrested and sentenced.
The 15-year-old accused shooter was charged with attempted murder and unlawful possession of a weapon. He was sentenced to seven years in a juvenile detention center last August.
Colombian prosecutors believe the local group acted on behalf of a paramilitary force known as Second Marquetalia, led by a former commander of the Revolutionary Armed Forces of Colombia (FARC) who operates under the pseudonym Ivan Marquez.
Colombian authorities ordered the arrest of seven people in the Second Marketalia in March in connection with the assassination.
