LINCOLN, Neb. (AP) — A Beatrice man serving decades in state prison for beating and raping a woman in 2011 has been sentenced to another three years in federal prison in a child pornography case.

34-year-old Joseph Buttercase was sentenced Friday after pleading guilty in March to production and transportation of child porn. In exchange for his plea, federal prosecutors dropped three other child pornography charges.

Buttercase is currently serving 26 to 41 years for the July 2011 beating, choking and raping a 29-year-old woman after they argued at his home.
