Man Dies in Brazil Zoo Lion Enclosure Attack

A young man’s lifelong obsession with lions ended in tragedy yesterday morning when 19-year-old Gerson de Melo Machado deliberately climbed into a lioness enclosure at the Arruda Câmara Zoobotanical Park in João Pessoa, Brazil, and was killed within seconds.

Known locally as “Vaqueirinho,” Machado had spent much of his life battling severe schizophrenia and had been abandoned by his family as a child. Friends and social workers who knew him told authorities that he repeatedly spoke of wanting to “live with lions” and even tried years ago to stow away on a plane to Africa to become a lion tamer. In the days leading up to the incident, police had detained him twice for erratic behavior, part of more than ten official reports filed against him over recent years.

Security camera footage and videos recorded by visitors show the teenager scaling a wall more than six meters high, using a tree branch to lower himself into the habitat of Leona, a 19-year-old lioness. As soon as he touched the ground, the animal charged, biting his neck and causing massive blood loss. Despite frantic attempts by zoo staff to distract her, Machado died at the scene before rescuers could reach him.

The Paraíba Institute of Forensic Science later confirmed the cause of death as fatal neck trauma from the mauling. Leona, who has lived at the park (commonly called Bica Zoo) since she was a cub, was examined by veterinarians and showed no injuries. Officials ruled that she acted on natural instinct when an intruder entered her territory, and no euthanasia is planned.

The case has renewed urgent calls for better mental health support for young adults in Brazil who “age out” of state care at 18. Counselors familiar with Machado described his death as heartbreaking but foreseeable, pointing to repeated failed attempts to provide him consistent psychiatric treatment. Brazil’s public mental health network, already stretched thin, often leaves people with serious conditions without follow-up care once they reach adulthood.

Zoo authorities emphasized that the enclosure met all federal safety standards set by IBAMA, Brazil’s environmental agency, and that staff followed emergency protocols the moment the breach was detected. The park remained closed Sunday while municipal environmental officials and civil police continue their joint investigation.
