SECURITY-WIDEFIELD, Colo. — A Colorado Springs family is mourning the loss of 6-year-old Simon Currat, after he suffered a rattlesnake bite while out on a trail.

It happened on July 5 in the Blue Stem Prairie Open Space, which is located just south of the Colorado Springs Municipal Airport.

According to a GoFundMe set up in support of the family, Currat was with his father and younger sister when he encountered the rattlesnake.

The El Paso County Coroner’s Office confirmed Currat was moved to Children’s Hospital in Adams County after the incident.

He died there four days later.

According to Colorado Parks and Wildlife, rattlesnakes are not aggressive, but will defend themselves if threatened or provoked. That can sometimes happen accidentally, if for example, a hiker doesn’t see a snake and steps on it.
