LINCOLN, Neb. (AP) — A 37-year-old Lincoln man must serve more than six years in prison for possessing child pornography.

U.S. Attorney Deborah R. Gilg announced Monday that Kenneth Charles Poston III also was ordered to pay $2,000 in restitution. He will be under supervised release for 10 years once he finishes his 78-month sentence.

Investigators with the Lincoln Police Department became aware last June of a computer sharing child pornography. They linked the computer to Poston’s address and took him into custody.

Authorities found he had about 50,000 images and almost 400 videos involving child pornography.
