I recently hired a new employee from an agency. They assured me that the performed a background check and there were no issues. In subsequent discussion, she disclosed to me that she had in fact been arrested and convicted of a crime about 8 years ago. As a result, I had another background check performed and discovered that she has had 2 other aliases that she has used in the past. However, in the past 8 years, she has kept the same name other than changing her middle initial. The other thing that is odd is that her credit report only includes one activity and she is 30 something. Her performance seems solid to date, but I am concerned about these other issues. Why would someone have multiple aliases unless they had something to hide? Suggestions for next steps would be appreciated.
