A high school senior collapsed and died during a basketball game at his small school in southeast Nebraska this week.

KOLN television reports that Terron Jones died Wednesday while playing basketball in the Johnson-Brock high school gym.

Superintendent Jeff Koehler says Jones and several other students had just finished one game and were starting a second one when he collapsed.

Koehler says it’s not clear what happened. Jones had not been complaining about feeling ill beforehand and didn’t appear to have any injuries.

A coach that was in the gym performed CPR until paramedics arrived. Jones was taken to an area hospital where he died about an hour later.

Jones had a twin sister, a younger sister and three adopted siblings who all attend Johnson-Brock schools.
