SANTA ANA, Calif. (AP) — A Southern California man has been sentenced to 4½ years in prison for his role in a scheme that used large-scale identity theft to obtain millions of dollars in tax refunds.

Federal prosecutors say 47-year-old Karen Pogosian of Sun Valley was also ordered Monday to pay $277,617 to the Internal Revenue Service.

Pogosian pleaded guilty in September to one count each of bank fraud and aggravated identity theft.

Court documents say the scheme involved more than 7,000 false tax returns using stolen identities. Together they claimed approximately $38 million in refunds and about $14 million was laundered through bank accounts.

The case was part of a larger probe that brought charges against 14 people. Nine have pleaded guilty, two are fugitives, two are awaiting trial and one is awaiting extradition.
