OMAHA, Neb. (AP) — An Iowa man who was previously sentenced to life in prison for a murder committed in Nebraska when he was teenager has been resentenced.

Douglas County District Judge Mark Ashford on Monday sentenced 53-year-old Kelvin Anderson, of Waterloo, Iowa, to 82 to 100 years in prison for the 1977 killing of Robert McGinnis.

Anderson will be eligible for parole in three years.

Anderson, who was 15 at the time, shot and killed McGinnis during a robbery in Omaha.

The new sentence was prompted by a U.S. Supreme Court ruling that says judges must have the ability to sentence juveniles to something other than an automatic life term.
