Argentine authorities have confirmed the arrest of a Colombian national in Buenos Aires linked to the assassination of Senator Miguel Uribe Turbay, a leading presidential candidate in Colombia’s 2026 election. The suspect, identified as Brayan Cruz, was detained following an investigation into the March 2025 killing that shocked Colombia’s political landscape. According to verified reports from Colombian and Argentine law enforcement sources, Cruz was apprehended in a coordinated operation after digital evidence, including chat logs and financial transactions, tied him to the planning and execution of the attack.
The assassination of Senator Uribe Turbay occurred on March 15, 2025, during a campaign rally in Bogotá, where he was fatally shot by a gunman who fled the scene. Uribe, a prominent figure in Colombia’s conservative political movement and a vocal critic of armed groups, was widely seen as a frontrunner in the race to succeed President Gustavo Petro. His killing triggered nationwide protests and intensified scrutiny over security failures during high-profile political events. Colombian prosecutors have since charged multiple individuals in connection with the murder, alleging involvement from both local criminal networks and international actors.
Investigators revealed that Brayan Cruz communicated with an accomplice using the alias “Gabriela” through encrypted messaging apps in the weeks preceding the assassination. These chats, recovered during forensic analysis of seized devices, allegedly detailed logistical support for the operation, including surveillance of Uribe’s public appearances and coordination of escape routes. While the content of these messages has not been made public, judicial sources confirmed to international media that they form part of the evidence presented during Cruz’s initial hearing in Buenos Aires.
Argentine authorities arrested Cruz under an active Interpol red notice issued by Colombia’s Attorney General’s Office, which requested his provisional detention pending extradition. The arrest took place in the San Telmo neighborhood of Buenos Aires after months of surveillance by Argentina’s Federal Police in collaboration with Colombia’s DIJIN investigative unit. Officials stated that Cruz had been using a false identity and frequently changed residences to avoid detection, though he maintained regular contact with known associates in Medellín and Cali.
Colombia’s government has formally requested Cruz’s extradition to face trial in Bogotá, where he is expected to be charged with homicide, terrorism, and conspiracy to commit aggravated murder under Articles 103 and 306 of the Colombian Penal Code. Legal experts note that if extradited, Cruz could face a maximum sentence of 50 years in prison if convicted on all charges. However, the extradition process may take several months, as Argentine courts must first review the legitimacy of the request and ensure due process guarantees are met under bilateral treaties between the two nations.
The case has drawn attention to the growing threat of transnational criminal involvement in political violence across Latin America. Analysts from the International Crisis Group have warned that assassinations targeting presidential candidates often involve networks that operate across borders, exploiting gaps in regional intelligence sharing. In Uribe’s case, investigators believe the killing may have been orchestrated to destabilize Colombia’s democratic process ahead of a pivotal election, though no armed group has claimed responsibility.
Miguel Uribe Turbay, 42, was a senator representing Bogotá and a member of the Democratic Center party. He was the son of former Colombian Vice President Francisco Santos Calderón and a grandnephew of former President Julio César Turbay Ayala. Known for his hardline stance on security and opposition to negotiations with guerrilla groups, Uribe had survived multiple threats prior to his assassination. His death marked the first killing of a major presidential candidate in Colombia since the 1990 murder of Carlos Pizarro León Gómez.
As of April 2026, Brayan Cruz remains in custody at the Ezeiza Federal Penitentiary in Buenos Aires awaiting a decision on his extradition. Colombian prosecutors have submitted a formal request containing over 800 pages of evidence, including witness testimonies, ballistic reports, and digital forensics. A hearing to review the extradition petition is scheduled for May 12, 2026, before Argentina’s National Criminal and Correctional Federal Court No. 12. No further delays have been announced, though defense lawyers for Cruz have indicated they may challenge the request on grounds of potential political motivation.
