If you're looking for just equipment / stats, then you should be able to go to http://us.battle.net/wow/en/ and search for the names in the "Search armory, forums, and more ...' box in the upper right.
I'm not sure if Blizzard only returns active characters or not.
The only other way to 'find' old WoW characters, that I know of, is to reactivate your account and login to your account. They should still be intact.
