Received the same email from the same person but with a different lawsuit #1731984 along with the same info. as you (T. Moore) received. downloaded the item. it was on "official" Department of Justice letterhead with his name, address 116 Nash Street East, Wilson, New York, NY & phone #212-845-9724
I got the same message But isn't it interestig that they use Eric Holder's name. They can't send you a debt notice by email. Also if they call you they are very very foreign sounding.
