A charter school alerted authorities to a 29-year-old sex offender who tried to enroll there, pretending he was just 12, in what sheriff’s officials said Friday may have been an attempt to lure children into sexual abuse.

The Yavapai County sheriff’s office also said Neil Havens Rodreick II conned two men he was living with and having sex with into believing he was a young boy.

A total of four men were in custody in the case Friday on various charges, including fraud, forgery, identity theft and failure to register as a sex offender.

Two of the men — “were very upset when the detectives told them they had been having a sexual relationship with a 29-year-old man and not a pre-teen boy,” Quayle said.

Uh — I’m glad someone noticed.
