(AP) — A Gretna woman accused of embezzling more than $4 million from the tobacco and candy business she worked for is facing tax evasion charges.

The Nebraska Department of Revenue and the Sarpy County attorney opted to pursue the tax evasion charges against 54-year-old Caroline Richardson after her former employer, Colombo Candy and Tobacco Wholesale Co, declined to press charges against her.

Instead, the company has gone after an Iowa casino. In a federal lawsuit, Colombo says Ameristar Casino should have known that Richardson was gambling with ill-gotten money.

But Sarpy County Attorney Lee Polikov says Richardson owes $430,000 in unpaid taxes for the $4.1 million she stole from 2010 to 2011. She is charged with three counts of tax evasion and faces up to 15 years in prison if convicted.
