The Murders of Pablo Medina and Antonia Almada

Status boundary: Vilmar Acosta's responsibility as the instigator was established by a Paraguayan judgment and upheld on appeal. That judgment does not itself establish final criminal responsibility for every person accused of planning, carrying out or assisting the attack.

A reporter and a young passenger

Pablo Medina, 53, had spent sixteen years reporting for ABC Color from Paraguay's eastern border region. His work examined marijuana production, trafficking and the overlap between criminal networks and local politics. The Committee to Protect Journalists documented years of threats connected to that reporting. His brother Salvador, also a journalist, had been murdered in 2001.

Antonia Almada was 19. She and her sister were traveling with Medina on the day of the attack. Treating Antonia only as a footnote to the killing of a prominent reporter would erase the second life taken: the criminal case, later judgment and this archive identify both victims.

The road near Villa Ygatimí

Medina had spent October 16 covering an agricultural story and was returning toward Curuguaty. On a rural road near Villa Ygatimí, two camouflage-clad men intercepted his pickup. Medina and Antonia were shot and killed. Antonia's sister survived and became an important witness.

Early reporting linked the attack to Medina's investigations of the marijuana trade in Canindeyú. That connection was initially an investigative theory and public allegation—not yet a verdict. The later prosecution would focus on former Ypejhú mayor Vilmar Acosta Marques and members of his circle.

Phones, flight and extradition

Investigators used telephone records and witness evidence to reconstruct communications around the ambush. Prosecutors alleged that Acosta coordinated the killing and that Wilson Acosta Marques and Flavio Acosta Riveros were the gunmen. Acosta fled to Brazil, where authorities detained him in March 2015. He was extradited to Paraguay in November 2015.

Arnaldo Javier Cabrera López, Acosta's former driver, received a five-year sentence in 2016 for failing to report a punishable act. He was definitively cleared of intentional homicide in that proceeding. The distinction matters: his conviction was not a murder conviction.

The judgment against Vilmar Acosta

In December 2017, a Paraguayan tribunal found Vilmar Acosta guilty of instigating the murders. It imposed 29 years in prison and a further 10-year security measure. The court concluded that Medina's reporting and Acosta's unsuccessful defamation action formed part of the motive to silence the journalist. An appeals court upheld the sentence in December 2018.

UNESCO described the result as Paraguay's first conviction of the intellectual author of a journalist's murder. That institutional significance does not diminish Antonia's identity as a co-victim, nor does it convert pending or separate allegations against other people into convictions.

Separate proceedings in Brazil

Brazilian authorities arrested Flavio Acosta in 2016 and Wilson Acosta in 2020. Because Brazil treated them as Brazilian citizens, extradition did not provide the route Paraguay sought. The most recent detailed source records located for this page described Brazilian proceedings rather than final Paraguayan judgments against them; CPJ reported that Wilson was later released after Brazil rejected extradition.

For that reason, this archive labels the case adjudicated with respect to the convicted instigator, not wholly closed. It identifies Wilson and Flavio only as accused alleged gunmen unless and until a final judgment establishes otherwise.

What the case established

The 2017 judgment supplied a rare judicial finding about who ordered the killing of a Paraguayan journalist. It also demonstrated the value of cross-border arrest and extradition, telephone analysis and witness testimony. Yet its strongest editorial lesson is narrower: one authoritative conviction can resolve a central role while other alleged roles remain legally distinct.
