Google lists our site under lost domain name

[creativeone]

My client nkhn.info was originally nkhn.org. One of the Board members allowed the domain name nkhn.org to expire and they lost it. They purchased nkhn.info and we quickly set the site back up with that domain. Now when you go to google and search nkhn.org their pages are still showing but under the nkhn.org which is a drug company. Their site is in Joomla on Godaddy hosting. Is there some kind of redirect script or anything I can do to get google to recognize the new domain and not the old one. How is it possible that the site still shows up when you click one of the links like http://www.nkhn.org/calendar/events-in-2011/178.html if the website files are on nkhn.info? Very strange and kind of scary.

I think you are seeing the catched page, if I am not wrong you are seeing this information in google result.
If this is the case then don't worry it will take atleast 3 months for google to index again and after that your problem will resolved.
But if you are facing another problem then i need more explanation for any resolution.
