SYDNEY, N.S. — The chaos of screaming, crying people, after an SUV and a truck pulling a camper collided, is something Liam Bernard and Shane Bernard may never forget. Seeing the hand of a man trapped in the smoke-filled truck, pressed to the window as other men shut the door, saying they couldn’t help, is another thing that disturbs them. “The guy (walking away) was in tears … you could see the distress in his eyes. He was terrified,” said Shane, who is not related to Liam.
