Jesus Valencia-Martinez, 32, was killed on Independence Day in an accident at Front Site Fire Arms Training Institute.

Valencia-Martinez died while participating in a "zip line" activity.

Known also as a zip wire, aerial runway, death slide or Tyrolean crossing, such a device usually consists of a pulley suspended on a cable mounted on an incline. It is designed to enable a user propelled by gravity to traverse from the top to the bottom of the inclined cable by holding on to the freely moving pulley.

His 10-year-old daughter had just completed the same exercise and was in the process of being retrieved from the line by a "scissor lift," a platform that raises up and down, allowing the operator to unhook the rider and equipment from the line.

While his daughter was being retrieved, however, Valencia-Martinez was sent down the zip line and collided with the lift.

He was pronounced dead at the scene.

Although the sheriff's office is investigating the incident, Nye County Sheriff Tony DeMeo said there is no reason to believe that what happened was anything other than an accident.

"We're looking at it as an unfortunate incident," DeMeo said. "We don't see any criminality."

The equipment operator at the time of the accident was a 16-year-old.

"We don't know if the state will have any issue with a 16-year-old running the scissor lift," DeMeo said.
