“The oldest little boy, he kept saying, ‘Don't look at him. Don't look at him. If you ever look at him, you'll never forget it,'" she added.
Smith's wife, Patricia, says she feels numb.
“(It’s) kind of like something's sitting on my chest. (It's) like a nightmare I can't wake up from,” she said.
Investigators believe the weight of the trailer and the children plus the incline of the hill were factors in the tragedy.
Patricia says she'll always remember how much the grandchildren meant to her husband.
“He took them up once, came back and then took them up again and last time he didn't come back,” she said.
Six of the seven children were hurt, but none seriously. They were taken to a hospital.
Meanwhile, many are more concerned about the emotional toll this accident might have on the seven grandchildren.
“It was just the most horrible thing for poor little children to go through what they did,” Chisolm said.
