The attack was the second major and second deadliest school shooting in Brazil, after the Realengo massacre in 2011, where 12 people were killed. It is also the ninth fatal school shooting in Brazilian history.

The shooting has inspired many copycat killings in and outside of Brazil.

At around 9:00 a.m. on Wednesday, 13 March 2019, Guilherme Taucci Monteiro shot his uncle Jorge Antônio de Moraes, inside Jorge's car dealership. Moraes was taken to the hospital but succumbed to his injuries, dying hours later. According to the investigation, Luiz Henrique de Castro was planning on killing a neighbor of his that was an electrician because they had had a misunderstanding months before. They had a pact, in which each one would kill someone before the school massacre. An hour and a half before the school attack, Henrique went to his neighbor's house. Finding the gate closed and locked, he persistently called him out, but the man did not answer and so Luiz went away.

On the same day, one of the killers posted a series of photos on a social media platform, where he appeared with a skull mask, holding the firearm he would later use and doing a gun sign with his hand against his head. The two attackers then drove to the school in a white Chevrolet Onix that Henrique had legally rented at Localiza.

The crime occurred at around 9:30 a.m. Guilherme Taucci Monteiro, 17 years old, and Luiz Henrique de Castro, 25 years old, entered the building hooded, with combat boots and balaclavas with skulls. Taucci entered the building first. He then turned around and began shooting at two school staff members as well as several students at a distance of approximately 3 feet (0.91 m) in front of him, before entering the main patio in search of more potential victims. He disappeared from the camera and then moved on to the institution's linguistics center.

By this time, Henrique appeared on camera entering the building in a hurry while holding several weapons, including a compound bow, which he eventually dropped on the floor and was unused in the attack. He approached the wounded victims lying on the ground and struck them with a hatchet, at which point, fleeing students started to run from the patio towards the school entrance hall. On their way, he encountered Taucci, who was still in the entrance hall, at which point Henrique engaged in a fistfight with a female student before she fled. Other students who had hidden when they first heard gunshots were able to avoid being shot. Five students between 15 and 17 years old and two school staff members were killed.

According to the 2017 School Census, the institution had 358 students between 6th and 9th grade (middle school and freshman year) and 693 students in secondary school. The school was locked down by police, who searched it and found a .38 caliber revolver, speedloaders, a crossbow, a compound bow, Molotov cocktails, a hatchet and a wired bag. A bomb squad was dispatched to the scene and found that it was a fake explosive.

The aircraft exploded at the time of the crash, and there were no survivors. The Regional Service for Investigation and Prevention of Aeronautical Accidents (Seripa) was called to investigate the causes of the accident.

Tracking data from Flightradar24 showed unusual altitude variations followed by a "dramatic descent" shortly before the plane crashed. Visual evidence suggested structural failure of the aircraft. Western intelligence reported that an explosion likely caused the airplane to crash.

The aircraft, manufactured by Brazilian company Embraer, had been associated with Prigozhin since 2018. It was barred from the United States due to sanctions imposed on Prigozhin after his involvement in the Russian interference in the 2018 United States elections.

While official Russian sources downplayed the crash, some intelligence agencies and international leaders suggested it was a politically motivated assassination. Prigozhin's previous criticism of the Russian Defense Ministry and open rebellion against Russian government were cited as potential motivations for foul play. The deaths of Prigozhin, Utkin and Chekalov are among several sudden deaths of Russian officials since 2022 considered suspicious.

The Wagner Group, a Russian state-funded private military company led by Yevgeny Prigozhin, had played an important role in the Russian invasion of Ukraine. Prigozhin was a close confidant of Russia's president Vladimir Putin. He began openly criticizing the Russian Defense Ministry for mishandling the war effort, eventually saying their reasons for the invasion were lies. On 23 June 2023, he led the Wagner Group in a one-day rebellion against the Russian Defense Ministry, which was resolved through negotiations that allowed Prigozhin to evade punishment. Some believed that this immunity would not last long, with analysts subsequently regarding him as a "dead man walking". On the day of the crash, Prigozhin was reported to have just returned from a trip to Africa. A posthumously released video of Prigozhin believed to have been filmed days before his death showed him acknowledging threats to his life.

On Vremya, the flagship news program of the state-controlled Channel One, the disaster's coverage was confined to a 30-second report on that evening's edition. Other state media reported on the incident sparingly, voicing the official version of "violation of flight safety procedures". At Wagner Center in Saint Petersburg, flowers and candles were placed at a makeshift shrine, and the building's windows were lit up in the shape of a cross. Grey Zone declared Prigozhin a hero and a patriot who it said had died at the hands of unidentified people whom it called "traitors to Russia". Other makeshift memorials appeared in Moscow, Novosibirsk and Rostov-on-Don, which was occupied by Prigozhin and his forces during the Wagner Group rebellion.

There was no immediate comment regarding the crash from the Kremlin or from Putin, who was at an event commemorating the 80th anniversary of the Battle of Kursk when news of the incident broke out. Prigozhin's press secretary declined to comment on the incident, as did surviving members of the Wagner Council of Commanders. On 24 August, Putin issued a statement which called Prigozhin "a person with a complicated fate", adding that "he made some serious mistakes in life, but also achieved necessary results". On 25 August, Russian presidential spokesperson Dmitry Peskov dismissed speculation over Putin's culpability in the crash as an "absolute lie". He later said that the possibility that the crash was premeditated was not being ruled out.

Pro-Kremlin journalist and RT chief editor Margarita Simonyan said she was "leaning toward the most obvious" version, also alluding to intentional downing. Rossiya-24 host Vladimir Solovyov accused Ukraine and its allies of spreading false news of Prigozhin's death but later retracted his statements. Asked by a journalist for a reaction at the sidelines of the 15th BRICS summit in South Africa, Russian foreign minister Sergei Lavrov refused to comment.

A poll conducted by Alexei Venediktov, former head of the Echo of Moscow radio station, found that 60% of respondents believed Prigozhin's airplane was either shot down or blown up on board, and 17% believed he had staged his own death. Only 1% believed the aircraft crash was accidental.

In response to news of Prigozhin's death, United States president Joe Biden and United States National Security Council spokeswoman Adrienne Watson both stated that the incident came as no surprise. When asked about the attribution of responsibility, Biden added, "There is not much that happens in Russia that Putin is not behind, but I don't know enough to know the answer." White House press secretary Karine Jean-Pierre later said that the Kremlin had "a long history of killing opponents", and that it was "very clear what happened" to Prigozhin.

Mykhailo Podolyak, an adviser to Ukrainian president Volodymyr Zelenskyy, called Prigozhin's death a "demonstrative elimination" and a signal from Putin to Russian elites against disloyalty ahead of the 2024 presidential elections, adding that "Putin does not forgive anyone for his own bestial terror." Zelenskyy himself denied any involvement by Ukraine in the crash, but said "everyone understands" who did it.

Estonian prime minister Kaja Kallas called the crash a reminder of Putin's ability to eliminate opponents and scare off dissent, while Polish foreign minister Zbigniew Rau said that those who threatened Putin's power do not "die naturally" and expressed strong doubts about the crash being accidental.[13] The French government expressed "reasonable doubts" about the cause of the crash, and added that Prigozhin was "the man who did Putin's dirty work" and left behind "mass graves" in Africa, Ukraine, and Russia.[85] Moldovan president Maia Sandu also commented on Prigozhin's death, saying it only confirmed the risks coming from Russia, "a country that has no justice", which extend to its neighboring countries.

Belarusian president Alexander Lukashenko stated he could not "imagine" Putin being responsible for Prigozhin's death, calling a supposed assassination to be "too rough and unprofessional".

In April 2024, a monument depicting Prigozhin and Utkin was unveiled outside the Wagner Group's chapel in Goryachy Klyuch, Krasnodar Krai, which also contains the largest cemetery for Wagner mercenaries. The municipal government said that the monument was built on private property and didn't need authorization from their side.

On Tuesday, August 10, 2021, a video went viral on WhatsApp groups, showing the moment when an unidentified young man, under the influence of drugs, recorded a video and confessed to having slit his father's throat, killed him, and ripped out his tongue.

The shocking footage that the young man recorded showed that he was preparing a hearty breakfast when he went to his father's room and said that he was sleeping. When he opened the door, the victim's body was found lying in a pool of blood and was a source of laughter for the suspect, who proudly showed his neck cut with a machete, as well as the tongue ripped out by him.

The drugged young man continues filming and asking his father and God for forgiveness for the crime he committed, which according to him only happened because his father had given him a lecture:

"May God forgive me! You're not talking too much, you understand my old side, I know it won't be right, you understand? ”, said the killer.

The young man continued eating next to his father's body and forwarded the video to several people, until, according to the internet user, the police arrived and arrested the suspect in flagrante.

Investigations to determine the causes were initiated immediately and are ongoing, with no deadline for completion.

Landy Milena Párraga Goyburo was born on February 26, 2001 in the city of Quevedo. She studied Social Communication at the Universidad Técnica de Babahoyo (UTB) and lived in the Ecuadorian city of Santo Domingo.

She participated in the beauty contest of Miss Ecuador 2022, representing Los Ríos Province, where she was placed fifth in the contest.

In December 2023, Párraga's name was mentioned in communications related to the Caso Metástasis investigations into the drug cartel activities. She was linked romantically to the drug trafficker es:Leandro Norero, who had been killed in prison in October 2022.

On April 28, 2024, Párraga was murdered while eating lunch in a restaurant. About 20 minutes earlier, she had published a photo on Instagram of her meal, revealing her location. Párraga was shot in the head and body, by a hitman who entered the restaurant and fled with an associate afterwards. She was pronounced dead at the scene. Párraga's killing was captured on the restaurant's CCTV.

Several theories abounded about the motivation for Párraga's killing, mostly due to her connection with Norero. Some speculated that Párraga's killing was ordered by his widow, or by Norero himself. The motive for the crime remains unknown.

Párraga was buried in her hometown of Quevedo on April 29, 2024, under the strongest security measures.
