Hundreds of people have turned out at a service to remember an Alabama bus driver who was shot to death trying to protect the young children on his school bus.

Mourners who attended a viewing service at a funeral home Saturday night remembered 66-year-old Charles Albert Poland, Jr., as a humble hero who taught Sunday School and often lent a helping hand to others.

The pastor of a nearby church helped comfort children who were on a rural Alabama school bus when a gunman killed the driver and took a 6-year-old boy.

Pastor Michael Senn said Wednesday, a day after the shooting, that the kids were "pretty shocked, traumatized."

He says "they saw everything that happened. They saw the man shoot the driver."

Authorities now believe the man is holed up in an underground shelter in a standoff.

Multiple neighbors have said suspect was paranoid and combative.
