An "evil" killer who battered his teacher to death with a baseball bat over his bad grades smirked in court before being sentenced to life in prison.
Willard Miller and Jeremy Goodale, who were 16 at the time, beat to death 66-year-old Spanish teacher Nohema Graber in a park where she regularly walked after school.
Judge Showers asked Miller to step forward before sentencing him to life in prison when he was seen smirking after the "heinous act" saw his eligibility for parole extended to 35 years - despite the state prosecutor asking for the 30 years.
