Where can a Murray hide? How about Ireland?

View Larger Map
Faced with credit card fraud, a cheating boyfriend, getting kicked out of school, and a troubled home life, did Maura decide to start a new life far from her troubles? And if so, how has she managed to fly under the radar for 8 years?
Is it possible to drive to Canada and take a plane to Ireland, where there are Murrays on every street?
You need a passport to enter Ireland. But does Ireland have to report entry to the U.S.? That's still something I'm researching.
The reason I ask: a source close to Fred Murray claims he or a close family member planned a trip to Killarney, by way of Dublin. Not sure when the trip was to take place or how close it was to Maura's disappearance, but the family had some interest in Killarney as a destination.
Tell ya what. If I ever decide to disappear, this would be a nice place for a long repose.
