On the morning of the accident, William asked to borrow the family car but died in a fatal crash shortly after. Mary Berry was informed of the accident by a police officer who came to her door. She and her husband rushed to the hospital, where they said goodbye to their son. William's sister, Annabel, was with him but survived the crash.
