The company has a check that has expired that belongs to us and will reactivate the check for a $$$ fee.

Same here.  A check will expire, the money will go to the government unless they resend the check for a fee...

I spoke w/ Julie Cork (or LaCork).  She claimed she was with a law firm, Luther-Anderson of Chattanooga, TN.  She was calling to follow up on an uncashed $175,000 cashiers check from the American Shoppers Network mailed to our home address.

I called the law firm she referenced and they do not have an employee by her name.  Web search the company, American Shoppers Network, and there are stories of scams.

Same here ! They said call Bank of America at this number 202-239-5132 or $175000.00 goes to the Gov.
 American Shoppers Network scam also and same law firm. She claimed to be Jenny Simons.

I too just was contacted by a person identifying themselves as Jennie Simmons from the law firm of Luther-Anderson Chattanooga, TN.  Imagine my excitement to be told I had won $175,000!  
Fortunately I had the presence of mind to refrain from giving any personal info and promptly called a family member to check into this.  That poor law firm, having their name attached to a scam group is a shame.  
Hardworking people versus con artists - the saga continues..
