(CNN) A third member of an Oklahoma high school track and cross-country team died Saturday, about a week after a pickup truck hit six team members who'd just started a practice run.

Moore Public Schools confirmed the death of senior Kolby Crum on its Facebook page . Kolby's family released a statement through the school district.

"He finished his race in heaven this morning," the family's statement read.

Superintendent Robert Romines said in a statement that the school district has "united even more" to support the district family. Moore is a city just south of Oklahoma City.

"Kolby has left his legacy with us — that of kindness, strength and inspiration," Romines wrote. "I ask that you also continue to support our students who were injured and are physically recuperating."
