Iowa Teens Plead Guilty in Spanish Teacher's Murder

Two Iowa teenagers pleaded guilty to first-degree murder for ambushing and killing their high school Spanish teacher, Nohema Graber, with a baseball bat in a park. The attack was carried out because of a bad grade Graber had given one of the teenagers. The teacher's body was found hidden in the park under a tarp, wheelbarrow, and railroad ties. As part of an agreement with prosecutors, one teenager will receive a sentence between 30 years and life in prison, while the other will receive a sentence between 25 years and life.
