The Attorney General’s Office advanced in a second phase in the investigation into the assassination of the senator and presidential candidate, Miguel Uribe Turbay, with the identification and prosecution of Simeón Pérez Marroquín, alias El Viejo, alleged intermediary between the determiners and the criminal group that carried out the attack on June 7 in western Bogotá.
The evidence shows that this person would have been contacted to organize everything related to the attack. In that sense, he allegedly entrusted the criminal plan to Elder José Arteaga Hernández, alias Chipi, who is responsible for defining the logistics and the roles that the others involved would play.
Alias El Viejo would also be involved in previous monitoring work on the victim. One of these, in March 2025, when the candidate was watched and photographed during a political meeting in the southwest of Bogotá.
Additionally, the material evidence places him in a meeting in the Danubio Azul neighborhood, in which he allegedly gave Katherine Andrea Martínez Martínez the firearm used in the attack, which had been modified to increase its lethality. This happened one day before the teenager shot Miguel Uribe Turbay.
On June 14, a week after the attack, Pérez Marroquín provided money and a cell phone to Katherine Martínez, and facilitated her escape to Caquetá. There, members of the Second Marquetalia structure of the FARC dissidents, apparently, would receive her and train her in sniper tactics and drone handling.
During the course of the investigation, it was learned that this man, from 2022, would be the leader of a criminal network dedicated to local drug trafficking, selective homicides and the instrumentalization of minors, among other criminal conduct perpetrated in Bogotá and various areas of the country.

For all of the above, a prosecutor from the Bogotá Section charged him with the crimes of homicide, conspiracy to commit a crime, use of minors to commit crimes; and manufacturing, trafficking, carrying or possession of firearms, accessories, parts or ammunition, all aggravated conduct.
The charges were not accepted by the defendant, who must comply with a security measure in a prison.
Simeón Pérez Marroquín, alias El Viejo, was captured in an action coordinated with the National Police and the Colombian Aerospace Force (FAC), in the Brisas del Guejar village, in Puerto Lleras (Meta). With today’s decision, he becomes the ninth person prosecuted for the assassination of Miguel Uribe Turbay.
