Toddler Hit, Killed by School Bus - kcentv.com - KCEN HD - Waco, Temple, and Killeen

(KCEN) -- It's a parent's worst nightmare that came true for a southeast Texas family.

Their toddler was hit and killed by a school bus after running into the street.

It happened Tuesday afternoon in Chapel Hill.

That's where police say a mother crossed the street in front of a stopped bus and didn't realize her daughter had followed her into the road.

But the bus moved forward, hitting the 18-month-old girl.

One witness says they chased the bus down, but not before it had traveled about 75 feet.
