Three bungee jumping instructors who threw a student to her death off a bridge without a rope have been pictured being booked in Brazil for homicide.

Maicon Fernandes Cintra, 42, Luis Felipe Feliciano Egoroff, 32, and Vitor de Freitas Gonçalves, 27, were filmed being led into custody in Limeira, São Paulo State, after they were arrested in connection with the death of 21-year-old Maria Eduarda Rodrigues de Freitas on Saturday.

All three kept their heads bent and their heads up as they were led into the police station, with Cintra and Egroff later seen in mugshots.

The three remain in pre-trial detention after they were charged with homicide after admitting to investigators they “blacked out” and couldn’t remember who was supposed to attach the safety line to the student before she plunged to her death off Skeleton Bridge.

They were seen in a sickening, now-viral video holding de Freitas, an aspiring physical education teacher, above their heads before hurling her head-first off the 130-foot bridge without attaching the rope first.

Two of the three allegedly tried to flee the scene before being tracked down by a military helicopter in a nearby wooded area, according to local media reports.

An attorney for the three instructors said that none of them had a clear ideas as to who was in charge, or who was responsible for attaching the safety line.

“I spoke with them, and they were all responsible for the inspection. First, they put on a kind of vest, and then the rope,” their attorney told Brazilian news outlet Metropoles.

“There were more than 30 people on the bridge, including the young woman’s boyfriend. The death was a tragic incident. They [companies linked to the prisoners] have been organizing this type of event for more than six years,” he continued.

A further three suspects who also worked at the jump center were taken into custody initially but later released without charge.

Egoroff has been pictured on Instagram during a previous jump, holding a child.

He regularly posted on social media, sharing the dangerous antics from Skeleton Bridge, an abandoned railway viaduct from where he allegedly ran an illegal rope-jumping company.

No date has been given for when the trio will next appear in court, after they were denied bond due to fears they would try to escape again.
