EMPORIUM, Pa. (AP) — Police say a Pennsylvania substitute teacher bought pictures of nude female students from one of their classmates.

Forty-one-year-old Jon Serianni was charged Tuesday with child pornography and corruption of minors after investigators searched his phone and found 190 pictures of girls who were nude or in sexually explicit poses.

The Emporium man was a substitute high school teacher in the Cameron County School District when he allegedly overheard some male students discussing the pictures. Serianni then texted one of the boys and offered to pay for some of them. The boy tells police he received less than $300 from Serianni.

Serianni faces a preliminary hearing Jan. 22 at the Cameron County Courthouse. Defense attorney David Shrager says he’s just begun investigating the charges.
