Good morning dear:.....,
This is Barrister David Labarr, I am confirming receipt of your email below. And Yes, My boss ( Dr. Karl A. Racine) left a cashier check of $100,000,00 USD with instruction that you would contact me for it just like you indicated in your message. My agreement with him was either to put the check on mail and send overnight to your address or get it remitted it for wire transfer direct into your account depending whether you would it so.
Now, I am happy to hear from you. I will like to give you some directions on what it takes to put a bank draft/ cashier check on mail here and send oversea and as well give requirement for wire transfer direct into your bank account.
First, if you want the cheque to be mailed to your house, all it will cost you is a security approval form to be enclosed along with your check to avoid interception of any kind, This approval will cost you just $150 USD only. But if you want the check to be remitted & wired to your account, then you will first get the IRS tax cleared and then check will deposited for transfer remittance, this IRS plus COT is $270 USD, Also, you are free to let me know if there is any other option you would like to receive this check. call me any time @ 343 600 0205
Kindly choose your prefer means and hurry to any nearby Western Union or Money gram or Send it Walmart to Walmart to details below:
Receiver's name: , Address is USA.
Please get back to me as soon as possible and advise me on what to do as time is of essence.
Sincerely regards David Labarr ESQ
