A 10-year-old Niagara County boy is dead after being trapped in a pile of snow. The Niagara County Sheriff's Office said the boy was digging a tunnel when it collapsed on him. He was pronounced dead at a local hospital. The boy was in the 4th grade. This has happened too many times. In fact, a similar incident happened a few years ago in Rochester. Cory Denoncourt, 10, died after he was trapped in a snow fort.
