READING (AP) _ A former Boyertown Area High School math teacher may face prison for having videos of children engaging in sex acts on his personal computer at school.

Thirty-eight-year-old Peter Lamana will undergo a Megan's Law assessment following his Berks County Court conviction Thursday of one count of sexual abuse of children. The evaluation is to determine whether he should be listed as a sexual predator. And he can face a minimum sentence of probation to nine months or a maximum of seven years in prison.

The school's technology manager found the child porn videos on Lamana's computer while investigating a virus affecting the school's system. He told the principal, who called police. Superintendent Harry Morgan says Lamana is on unpaid leave and "We do not anticipate he'll be back in the classroom."
