Received phone calls from this number on my cell phone and my work google voice number.  He left the following message on my google voice number: "[My name], I'm calling you because there was a package send to your address [states former address, not current address] and it involves fraud and I need to speak with you and have that package returned back to its rightful owner.  You can contact me, Mike Smith, at this address....I'm sorry, this phone number, but we will make a referral to the [County sheriff's office] or the [City Police] department if I do not get a follow up call from you.  Thank You"

I don't believe this for a second.  I haven't lived at the address he states in 6 months.  He didn't indicate what company he works for, gives a generic name, doesn't repeat back his phone number.  I'm not calling the number back.  I don't think anything is going to happen next.
