He got caught in a conspiracy against hitler and was given 3 choices. he could choose to defend himself personally in front of Hitler in Berlin, or if he refused to do so (which would be taken as an admission of guilt); (b.) he could face the People's Court (which would have been tantamount to a death sentence), or (c.) choose to commit suicide. For his family’s sake he choose suicide. Officially he died from natural causes.
