World War II ace Aust out of Jail after 8 years! He was in Jail???

I just came across a post through Google Alerts that Abner Aust, P-51 Mustang ace from World War II was "finally" released from jail following 8 years of imprisonment. I can't believe he was even in jail. How did I miss that? My wife and I ate dinner with him once (see photo).

See the story about his release from jail.

I am sorry to hear about it.
