KNOXVILLE, Tenn. (AP) - Two more people have received prison sentences in a scheme to defraud U.S. taxpayers by $10.8 million.

U.S. Attorney Nancy Stallard Harr's office says 52-year-old Luis Carvajal of Loudon was sentenced to 30 month in prison for conspiring to submit false tax returns and commit money laundering.

Fifty-year-old Amado Valdez-Morales of Oak Ridge received a 42-month sentence in the scheme.

Valdez-Morales, a Honduras citizen here illegally, also pleaded guilty to illegal entry by a previously deported felon. Once he's released from prison, he'll be subject to deportation.

A news release says the scheme included using fake ID documents to get refundable tax credits, resulting in $10.8 million stolen from taxpayers.

Carvajal faces about an $8 million fine. Valdez-Morales was fined $2.5 million.

Four others were already sentenced in the scheme.
