When Adolf Hitler heard of how Mussolini was executed and put on public display, he vowed he would not let this happen to him. Hitler shot his mistress and new wife, Eva Braunn, and then swallowing some poison, he shot himself in the mouth.
Adolf Hitler poisoned himself then shot himself in the mouth just like Mussolini. 
It was Mussolini who swallowed poison and shot himself not Adolf Hitler.
