When Hans and Sophie Scholl were arrested at the University of Munich on 18 February 1943 for spreading anti-war leaflets, Lafrenz was also put under investigation by the Gestapo.
As a result, she was sentenced to one year in prison on 19 April 1943, by the Volksgerichtshof (People's Court, first senate) for her role as a confidante.
Had it proceeded, she most likely would have been sentenced to death, but the Allies liberated the prison where she was held three days before her trial was supposed to commence, likely saving her life.
[11] In 1947, she immigrated to the United States,[12] completing her medical studies at Saint Joseph's Hospital in San Francisco, California.
[14] In 2019, she received the Order of Merit of the Federal Republic of Germany on her 100th birthday and was praised by German President Frank-Walter Steinmeier, who called Lafrenz a "hero of freedom and humanity".
[4][15][16] On 6 March 2023, Lafrenz died on Yonges Island, South Carolina, at age 103, as the last living member of the White Rose group.
