A York County man was sentenced to 20 years in prison for child pornography charges.
Lawrence B. Blevins Jr., 44, of West Manchester was convicted in November of downloading child pornography from the internet. He was sentenced Thursday.
Police say they began investigating Blevins as part of a larger internet child pornography investigation. Based on information from that investigation they obtained a search warrant and executed it in December 2011.
Officials say they found multiple computers and external storage devices in his room, finding over a half million images and hundreds of videos of child pornography.
