Rejected tenant applicant applied for electric service anyway?

[Denise B.]

I'm in the process of trying to fill an open unit.  One prospective applicant seemed great in person - very friendly, polite, punctual, gainfully employed, etc.  She said she had 'average' credit.  When I ran her credit, it was a disaster.  Low score, accounts in collection and a recently repossessed car.  I sent her a denial letter.  Well, I just received a letter addressed to her at the rental unit's address from the electric utility.  She applied for service at that address and was declined an account (she owed them over $6K).  Why would she apply for electric service when I denied her application?  I'm worried there's a scam in the making here.  Any thoughts?
