Two Iowa high school students killed their Spanish teacher last year as retaliation for receiving a bad grade, prosecutors said in court documents on Tuesday.
The documents reveal a possible motive in the case for the first time since the teenagers — Willard Miller and Jeremy Goodale — were arrested in November 2021. The boys, who were 16 at the time, face murder charges for the death of their 66-year-old teacher Nohema Graber.
