The University of Colorado Colorado Springs, which hosted the event, said the implement had “cleared certified barriers.”

An errant weight thrown by a competitor in a hammer throw event struck and killed a spectator at a youth track and field meet in Colorado, according to officials at the university where the competition was held.

The man killed by a flying weight thrown off-course during a Sunday high school track-and-field meet in Colorado Springs was a 57-year-old father there to watch his son compete, El Paso County coroner officials said.
