The woman, who has not been identified, is seen in video circulating on social media standing near the edge of a cliff at the Skeleton Bridge Trail in Limeira, wearing a helmet and with her arms outstretched. Three men lift her, and two of them throw her off the cliff.

The video appears to show the woman unattached to a bungee cord as she falls several feet to the ground below.

“According to the police report, at the time of the jump, the safety equipment was not properly fixed,” the governor’s office said in a statement. “The victim did not resist the fall and death was confirmed by SAMU (Serviço de Atendimento Móvel de Urgência, or emergency medical service) teams.”

It remains unclear why the bungee cord was not properly secured before she participated in the activity.

Six people were initially brought to the Limeira Police District for questioning. Three of them — men aged 27, 32 and 42 — were subsequently arrested in connection with the incident, the governor’s office said.

The men were arrested “in flagrante,” or caught in the act, on charges of homicide with eventual intent. Under Brazilian law, this charge applies to cases in which perpetrators did not intend to kill but engaged in a dangerous act that carried a fatal risk.

Officials did not identify the suspects.

“Investigations continue to determine the circumstances and possible responsibilities,” the governor’s office said.
