Moll and his wife died in a car accident while on return from vacation during the winter break of the 1968–69 season. Two charity matches were played for the benefit of the Molls' children, the first featured West Germany's 1954 FIFA World Cup winning squad in the line-up of the tournament's final, the second saw a combined squad of Eintracht Braunschweig and rivals Hannover 96 take on a Bundesliga all-star team. Moll's funeral in Braunschweig was attended by 4,000 people, including the West German national team and the entire squad of Hannover 96.
