(Portland, OR)  --  A former high school teacher in Beaverton is facing child pornography charges.  Police arrested 40-year-old former Aloha High School teacher Geoffrey Germano yesterday following a five-month investigation.  Police say he downloaded more than 70 images and videos of child porn.  Some of those files were allegedly accessed through the school district's Wi-Fi.  Germano worked as a special education teacher at Aloha before resigning last month.
