Campinas Cathedral shooting
2018 attack in Campinas, São Paulo, Brazil
On 11 December 2018, a gunman opened fire in the Metropolitan Cathedral in the Brazilian city of Campinas, São Paulo, killing five people and wounding four more. The event was reported by multiple news outlets.
Incident
The shooter entered the cathedral around 13:25 BRST (15:25 GMT). The officiating priest had left the cathedral prior to the attack and the suspect was not recognized by any of the church officials. The suspect entered the church while the Mass was still underway and sat in the back and watched the service for a while, before he began to fire his weapon. He killed four worshippers and injured another four. Police in the plaza outside of the church responded to the gunshots, and the gunman was hit in the side by police, before he committed suicide.
One day after the massacre, another victim had succumbed to his injuries at the hospital, and the fifth victim of this massacre was revealed, Heleno Severo Alves, 84 years old.
The incident was documented on the surveillance footage from inside the cathedral and allowed the police to review the timeline of the incident.
The PM works with the hypothesis that the crime was premeditated, as the shooter used enough ammunition to kill the victims and left only one bullet to commit suicide.
This brief starts where responsible research should: with the source description of “Campinas Cathedral shooting” as 2018 attack in Campinas, São Paulo, Brazil. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 2018 attack in Campinas, São Paulo, Brazil. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q59644807. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
