It could be an older listing that has not yet been removed. I suggest flagging the listing on the site to alert it to a Trulia moderator and contact them by sending an email message to: http://www.trulia.com/help/ask. They usually respond within 48 hours.
You can also call Trulia M-F from 7:00am-4:00pm PST at 888-466-3501 to request that the status be changed.
Good luck to you!
