A northeastern Pennsylvania man has been sentenced to 14 to 28 years in prison in the murder of his great-grandfather almost four years ago.
Notes scrawled in a school book were a key piece of evidence in the case.
Nineteen-year-old Cody Lee of Dallas, Pa., was sentenced Friday in Luzerne County Court to the term called for under a plea agreement.
Lee pleaded guilty to third-degree murder in August in the December 2009 shotgun murder of 80-year-old Herbert Lee.
Police alleged that Lee, then 15, carefully plotted the murder.
They said a classmate authenticated a school notebook in which Lee scrawled plans including "Finding grandpa's gun. Kill grandpa. Find money."
Authorities said the boy also planned to kill his father, who was able to wrestle the gun away from his son.
