Thanks Cyrus. Do you mean Fetch as Google? I'm not too familiar with that specific tool.
Just in case someone runs into the same issue that I've encountered, I'll include my final steps in remedying this problem (hopefully).
I was finally able to contact the webmaster of the other domain who agreed to take down the site. I contacted GoDaddy to confirm her site was down, since I wasn't risking getting my machine infected with malware. Next I went to Webmaster Tools and requested content removal, page by page until all of the bad URLs were submitted.
In my frustration and possibly paranoia, I've also had to battle with GoDaddy to get a new dedicated IP address since I believe this IP could now be "tainted" or flagged as a malicious or spammy.
Cyrus, you couldn't be more accurate. Extremely tough to wait out. Hopefully this will help someone out down the road.
Thanks again.
