The night at Estadio Monumental
On September 24, 2011, Universitario de Deportes hosted Alianza Lima at Estadio Monumental in Ate. After the match, violence broke out in the private-suite area of the south stand. Walter Oyarce Domínguez, a 23-year-old Alianza supporter, fell from an upper level and died.
Early reporting contained competing descriptions of exactly how the fatal fall happened. Those initial accounts were later tested in court through testimony, reconstruction and other evidence. For that reason, this file relies on the final judicial outcome rather than treating the first hours of reporting as settled fact.
The investigation and defendants
Within days, Peruvian courts ordered the detention of several men connected to the disturbances. David Sánchez-Manrique Pancorvo and José Luis Roque Alejos became the principal homicide defendants. Other people were investigated for different alleged roles in the disorder, and their legal responsibility should not be collapsed into the homicide convictions of Sánchez-Manrique and Roque.
The prosecution initially pursued the death as aggravated homicide with treachery, alongside public-disorder charges. That was the classification accepted by the lower court when it imposed 35-year terms in 2014.
The 2014 judgment
In March 2014, a Lima criminal chamber sentenced Sánchez-Manrique and Roque to 35 years in prison. The court accepted the prosecution theory that they were responsible for Oyarce's death and treated the homicide as aggravated.
The defense challenged the judgment. Because the case continued to the Supreme Court, the 35-year sentence was not the final word and should not be presented as the enduring legal classification.
The Supreme Court changes the legal classification
On March 15, 2016, the Transitional Criminal Chamber of Peru's Supreme Court changed an important part of the judgment. It rejected the aggravating circumstance of treachery and reclassified the killing as simple homicide.
The Supreme Court imposed 17 years for simple homicide plus eight years for public disorder, producing a total term of 25 years in prison for David Sánchez-Manrique Pancorvo and José Luis Roque Alejos. The court explained that the evidence did not support an ambush or surprise attack sufficient for the aggravating circumstance originally applied.
Why the final classification matters
Popular retellings often continue to describe the defendants as having received 35 years for aggravated murder. That reflects the earlier judgment, not the final Supreme Court resolution. The legally accurate archive status is that Sánchez-Manrique and Roque were convicted of simple homicide and public disorder and received 25-year total sentences.
The victim's father, Walter Oyarce Delgado, publicly said he accepted the Supreme Court decision and regarded the criminal process as concluded, while continuing to emphasize the wider cost of violence surrounding football.
