MINNEAPOLIS (AP) -- An Illinois couple convicted of defrauding Best Buy out of more than $32.8 million and failing to pay taxes on their fraudulent gains has been sentenced.

Prosecutors alleged that Russell and Abby Cole of Deerfield, Ill. systematically overbilled the Richfield-based electronics retailer for four years through an online auction program.

Russell Cole, president of Chip Factory, received a 15-year sentence Monday.

Abby Cole received three years' probation after telling the judge she needed to care for two of her children and aging mother.

Cole's co-conspirator, fired Best Buy vendor relations manager Robert Bossany received 7 1/2 years.

He got credit for working with investigators to record conversations with Cole and his wife.

Best Buy said it's made changes to ensure this doesn't happen again.
