She joked about who let her jump off a bridge, then staff threw her off without a rope.

A 21-year-old student fell 130 feet to her death in Brazil while her fiancé watched, leading to six arrests.

We trust adventure guides with our lives when we seek a thrill. But a simple mistake by the people in charge can turn a happy day into a nightmare in a second.

WHAT HAPPENED

Maria Eduarda Rodrigues de Freitas went to Skeleton Bridge in Brazil for a bungee jump. The 21-year-old sports student joked online about who let her jump.

Moments later, staff members threw her off the bridge. She fell 130 feet to her death because she was not tied to the rope.

Her fiancé watched her fall. A video shows the safety rope still lying on the ground. Police have arrested six people, including some who tried to run away.

WHAT THE EVIDENCE SHOWS

A fall of 130 feet from the bridge.

• The victim was 21 years old.
• A video showing the jump rope left on the ground.
• Six people arrested by the police.
• Two suspects who fled into the woods before police caught them.

THE BIGGER QUESTION

How do we make sure adventure sports companies are safe? Many people pay cash for quick thrills without checking if the guides have training or licenses.

This tragedy shows that a lack of rules can cost lives. We need to ask who checks these companies before they let people jump.

THE OTHER SIDE

The lawyers for the arrested workers have not made a statement yet. Some of the staff tried to run into the woods when the police arrived. Based on the video of the rope on the ground, the defense faces a very difficult case.

WHAT HAPPENS NOW

This accident will likely make local towns close down illegal jump sites. People who want to do extreme sports will need to be much more careful about who they trust.

WHAT WE STILL DON'T KNOW

Did the company have a license to run these jumps?

• Why did the staff throw her before checking the rope?
• What safety checks did they have in place?
