The father who kept his 13 children in deplorable conditions inside his California home was hit with new charges Friday related to his lying to obtain a home schooling license.

David Turpin — who was arrested along with his wife, Louise, when their children were discovered shackled inside the Perris, Calif., residence — was charged with eight counts of perjury relating to an affidavit he filed with the state Department of Education.

The Riverside County District Attorney’s Office said that the dad “certified under penalty of perjury that the children in the home were receiving a full-time education in a private day school.”

The status as a home school may have helped the Turpins avoid scrutiny from child protective services.

The couple has already been charged with 12 counts each of torture and false imprisonment, as well as nine counts of child abuse and seven counts of cruelty to a dependent adult.

They have pleaded not guilty to all of the charges.
