A shootout at a country music festival in Brazil has killed a man and a woman, and injured two more.

One of those killed was a 23-year-old female dentistry student and the other was a 26-year-old man.

Heloise Magalhaes Capatto – a fifth-year student at the State University of Campinas – was struck dead by a bullet at the event in Piracicaba, Sao Paulo State, in the early hours of 20th November.

She was buried in Elias Fausto – less than an hour away by car – later that day.

The other victim, Leonardo Victor Cardozo, was buried in Piracicaba on the same day.

The event – called Fervo – was headlined by sertanejo (Brazilian country music) duo Hugo & Guilherme.

During the main act, a commotion is reported to have started, with gunshots fired and four people hit by bullets.

One of the injured was merely grazed by a bullet and sought medical attention of her own accord before being treated and discharged.

The other wounded person – a 27-year-old man – suffered injuries to his ear and temple and is being treated at a private hospital.

Leonardo’s sister told local media how her brother was at the event with a friend and was trying to break up a fight between a couple when the assailant pulled a gun and fired multiple shots.

At the time of reporting, the gunman had not been identified, but police were seeking him for murder and attempted murder.

Reporters from local media outlets found traces of blood and broken bottles on the ground of the venue on the morning of 20th November.

The organiser, Burn19 Producoes, has said it had the correct permits for the event and added that it would co-operate with police.

It said that attendees were searched, that there were security guards on site, and that there were paramedics in attendance.
