TOPEKA, Kan. (AP) — A U.S. attorney says a Topeka man must serve more than six years in prison on a child pornography charge.

U.S. Attorney Barry Grissom says 43-year-old James A. Greer has been sentenced to 76 months in prison after pleading guilty to one count of distributing child pornography earlier this year.

Authorities say they discovered more than 900 images and around 290 videos containing child pornography.
