A former Dublin woman who bought a lavish home and a Cadillac Escalade in the same year she claimed her income was just $8,003 was sentenced today to six months in prison. U.S. District Judge Algenon L. Marbley also ordered Lisa Harper, 49, to spend six months in a halfway house after her prison stint and to pay restitution of $199,950, the amount court records show she owes in back taxes.
