For anyone that doesn't know by now, she married someone from her usual sets. Pretty common for pornstars to end up doing. They retire at that point. Most of the time, the marriage fails and the pornstar returns, but it's been a few years for Autumn, so that may be that for her.
She's retired. What exists of her is all there is.
Now, that said, She did a film called "Young, Hot and Bothered 3" in 2008 - which was after the marriage. Her last non-internet work before that was two years prior. She may have taken the third option for married pornstars. Sticking strictly to lesbian films, which for a while is what it seemed she had done. As of the date of this post, I've yet to find anything more recent since.
I should also mention that occasionally a pornstar will 'take a break' then come back under a new name, claiming to be 18 again
