ASUNCIÓN, PARAGUAY – On the evening of Wednesday, June 12, 2025, Sergeant César López Martínez, 26, of the Paraguayan National Police, was apprehended and arrested while attempting to smuggle approximately 442 grams of marijuana into Tacumbú Penitentiary, where he was on duty.

Sergeant López was caught during a security check as he entered the prison for a shift change, where bundles of marijuana were found attached to his body. According to reports from Telefuturo, he is suspected of attempting to sell the drugs to inmates.

Regarding the incident, Commissioner Alberto Morinigo, head of Police Station No. 4 in Asunción, expressed deep regret, stating, "The inmates would have been potential clients. Unfortunately, this incident has tarnished the institution's honor." Sergeant López is currently under investigation by the Public Prosecutor's Office and the internal audit department of the National Police, and he is reportedly exercising his right to remain silent.

 
Escalating Seriousness of Drug Smuggling in Prisons

This incident once again highlights the severe problem of drug smuggling within Paraguayan prisons. The direct involvement of a prison guard in drug trafficking raises fundamental questions about the security system of correctional facilities. Tacumbú Penitentiary is one of Paraguay's largest and most overcrowded prisons, having experienced multiple drug-related incidents and violent outbreaks in the past.

While the Paraguayan Ministry of Justice and the National Police are continuously working to eradicate drug distribution within prisons, the influence of drug cartels and the cycle of corruption remain significant obstacles. A correctional authority official, who wished to remain anonymous, pointed out, "Preventing influx from within is the most difficult challenge," adding that "prison guards, especially those facing economic hardship, are easily tempted by criminal organizations."

 
Ongoing Drug Crackdown and Countermeasures

In addition to Sergeant López's arrest, around 3:30 PM on the same day, Ministry of Justice agents discovered suspicious packages on the roof of the 'Wall 1' outpost within Tacumbú Penitentiary. A yellow package contained 1,400 grams of marijuana, while three blue packages contained 1,037 grams of cocaine. These drugs are presumed to have been thrown in from outside the prison or introduced through other routes.

These incidents collectively expose the vulnerable security systems and internal corruption issues within Paraguayan prisons. The Paraguayan government must continue efforts to strengthen prison security by expanding CCTV installation, enhancing body searches, and preventing corruption through improved welfare and salaries for prison guards. Furthermore, a multifaceted approach is necessary, including rigorous investigation and punishment of drug trafficking organizations, as well as expanding inmate rehabilitation programs to reduce drug demand within prisons.

 
This incident should prompt Paraguayan judicial authorities to devise stronger and more practical measures to stamp out drug distribution within prisons. The involvement of a police officer in criminal activity is a grave matter that erodes public trust, making thorough investigation, accountability for those responsible, and systemic improvements to prevent recurrence urgent.
