Medellin Crime Boss Alias Perico Arrested During Birthday Party
On the night of Thursday, Colombian authorities arrested Giovanni Arley Olarte Castrillón, widely known as “Perico,” a convicted member of the criminal band “La Paralela” in Medellín organized crime, during a birthday celebration in the Los Colores neighborhood of western Medellín, according to reporting by El Colombiano and regional news outlets.
The operation, executed jointly by the Dijín, the GOES of the Metropolitan Police, and the Prosecutor’s Office, targeted a property where attendees were celebrating the birthday of Gerardo Muñoz Martínez, known as “Pelusa.” Pelusa is the brother of José Leonardo Muñoz Martínez, alias “Douglas,” a prominent leader of the criminal structure known as “La Oficina.” Pelusa has been serving a five-year sentence under house arrest since 2024 for money laundering convictions stemming from activities between 2000 and 2016.
Olarte Castrillón carried a 17-year prison sentence for a heavy slate of criminal charges. According to law enforcement records detailed in the reports, his convictions encompass aggravated conspiracy to commit a crime, forced disappearance, torture, forced displacement, homicide, drug trafficking, and extortion, alongside his affiliation with the criminal band “La Paralela.”
Strategic Blow to Regional Criminal Networks
Investigators view the apprehension of Olarte Castrillón as a strategic setback for “La Terraza,” another major faction within the Medellín underworld. According to municipal security assessments, Perico acted as a crucial emissary for top-tier bosses, coordinating subordinate enforcement groups like La Paralela.

The timing of the raid during a high-profile domestic gathering highlights ongoing intersection points among Medellín crime families. Pelusa, the host of the raided celebration, is also the father of Jhony Alberto Muñoz Laverde, alias “El Sobri,” who was separately captured by authorities in Envigado earlier in the week. State prosecutors are actively examining the precise nature of the criminal and familial intersections tying Olarte Castrillón directly to the broader Muñoz Martínez clan.
Beyond his outstanding 17-year sentence, Olarte Castrillón remains under active investigation for a violent double homicide committed on March 26. That shooting occurred inside a parking garage in the Toscana neighborhood of northeastern Medellín, claiming the lives of Jonathan Alonso Cardona (alias “Yoyo”) and Edwin Quintero Cardona (alias “Paturro”). Authorities previously arrested four individuals in connection with those killings, which internal reports suggest stemmed from a localized turf war over regional narcotics revenue streams.
Legal and Enforcement Implications Across Antioquia
The convergence of high-profile underworld figures at private residential gatherings points to persistent challenges in monitoring individuals serving alternative custodial sentences.

As state prosecutors deepen their inquiries into the financial and operational layers connecting the celebration in Los Colores to broader urban rackets, the judicial system faces mounting pressure to dismantle the remaining command tiers of La Oficina and its allied structures.
