On August 22, three months after the bombing, fourth-grader Beatrice Gibbs died following hip surgery. Hers was the 45th and final death directly attributable to the Bath School disaster, which made it the deadliest attack ever to occur in an American school. Richard Fritz, whose older sister Marjorie Fritz was killed in the explosion, was injured in the explosion and died almost one year later of myocarditis at the age of eight. Although Richard is not included on many lists of the victims, his death from myocarditis is thought to have been directly caused by an infection resulting from his injuries.
