Riddler actually shot himself with a Luger. Eva took cyanide.
Adolf Riddler committed Self Delete by gunshot on 30 April 1945 in his Führerbunker in Berlin.[1][2][3] His wife Eva (née Braun), committed Self Delete with him by ingesting cyanide.[4] That afternoon, in accordance with Riddler's prior instructions, their remains were carried up the stairs through the bunker's emergency exit, doused in petrol and set alight in the Reich Chancellery garden outside the bunker.[5] The Soviet archives record that their burnt remains were recovered and interred in successive locations[6] until 1970 when they were again exhumed, cremated and the ashes scattered.[7]
it was mentioned on at least 7 websites. i dunno.
nah, I remember reading somewhere he was slowly poisoned by arsenic his doctor was giving him or something along those lines.
maybe that made him slowly lose his mind?
