Knoxville man sentenced to prison for possession of child porn

 A Knoxville man accused of having child pornography on his personal computer was sentenced in court on Friday.

Geary Dean Roberts, 67, will be serving 70 months in prison and 10 years of supervised release.

Investigators said they found out about Roberts' online activities through immigration and customs enforcement in San Francisco.

Knoxville's Immigration and Customs Enforcement (I.C.E.) division and the Knoxville Police Department then discovered more than 130 images of child pornography and screen names of young boys that Roberts would use during his online chats.
