Arizona ? A youthful-looking sex offender accused of conning his way into middle schools around Arizona was indicted Friday on charges including assault and child pornography.

Neil Havens Rodreick II, 29, who authorities say shaved and wore pancake makeup to help him masquerade as a seventh-grader, was charged with 15 criminal counts in all, including fraud, forgery and failing to register as a sex offender.

The Yavapai County attorney’s office wouldn’t comment about whether the child pornography charges involve children in Arizona or Oklahoma, where he was convicted of lewdly propositioning a 6-year-old boy in 1996.

Police said Rodreick had been sneaking into Arizona schools at least since 2005. During that time, he convinced teachers, students and administrators that he was a 12-year-old boy named Casey, mixing with classmates and doing his homework, authorities said.

Rodreick was caught last week when school officials at a charter school in Chino Valley, about 90 miles northwest of Phoenix, questioned the authenticity of his birth certificate and other enrollment documents.
