Delta Financial Trust Send me a check in a mail Ripoff St Thomas US Virgin Islands

Today I receive a mail signed on my name. The sender is ,,Delta Financial Trust'' from US Virgin Islands. In mail it says that I'm a winner of 36,750.06$ of the money ball international lotto/sweepstakes which was drawn on 29th may, 2007. In the envelope was a check that I deposit on my account in my bank.
I did that because I believed that really I'm a winner of that money. Fortunately I didn't cash up that check so tomorrow morning I will be heading to my bank to report this!!! Tonight I begin my exploration and fortunately find your site on the internet.
I talked with person that was mentioned in that mail named ,,Jim Bosco'', who told me that (after I told him that I deposited check on my account) now I should send 1850$ by Western Union to their representative in NY named ,,Mary Reynolds'' on this address 5521 Hazel Boulevard NY. BTW that person has really bad accent, kinda Asian or something like that. Than I was suspicious of all of that! And here I'm writing this post, which I hope will help to some other people and maybe to arrest those people! And in the end I hope that I won't have problems because I deposited this check cause I thought it was real.
