What is the easiest way to pull a report to see if a user has multiple profiles loaded in WF?

We discovered a possible issue with duplicate user profiles being added. This particular user was listed in the "Aaa - New User" home group, but then had another profile with all details and their correct department name listed as their home group and their report to info was all filled in correctly as well. We aren't sure how it happened, but want to make sure there aren't others.
