Whatever happened with the rape allegations against illusionist David Copperfield?

I checked wikiand googled it but there doesn’t seem to have been a mention of this for almost a year. Did it get resolved?

He made them disappear?

Maybe he disappeared the courthouse of the jurisdiction in question just like he disappeared the Statute of Liberty?
That’d make for a confused DA.
“Where the hell do I file these papers now? Darn those magicians…”

In all seriousness, I just used my best Google-Fu, and I had the same result the OP did.
This story is vanished like an Ipod mailed to a mysterious Nigerian businessman you met on Craigslist…

This Dec. 26, 2008 review of his show briefly mentions it and indicates that the case was dropped. “an FBI raid on the magician’s Las Vegas warehouse, part of a sexual assault investigation that produced no charges.”
