Three bungee-jumping instructors have been charged with the death of a young student who was thrown off a 130-foot bridge without a rope attached — as mystery swirls over a handheld camera she was carrying during her horrific final moments.

In total, six people have been taken into custody and questioned about the death of Maria Eduarda Rodrigues de Freitas, 21, in Limeira, near Sao Paulo, on Saturday, O Globo reported.

Of them, three instructors — Luis Felipe Feliciano Egoroff, 32, Vitor de Freitas Goncalves, 27, and Maicon Fernandes Cintra, 42 — were charged with homicide, the outlet said.

They are understood to be the three seen in a now-viral video as they lifted up the young student to launch her off the 130-foot “Skeleton Bridge” — with her plummeting to her death and the safety rope lying unused on the platform.

Two of the instructors fled once they realized what had happened to Rodrigues de Freitas as her horrified fiancé watched.
