Answer:
20 years.
Explanation:
Roland Gary killed a religious leader Robert Hardcastle nearly twenty years ago, stabbed him to death, he was found guilty of his crimes and then sentenced to death row, a fate which finally reached him 20 years later in a prison in Oklahoma. He always claimed that the stabbing of Mr. Hardcastle was done in self-defense, but neither the court or the appellation trials believed him enough to save him from the death penalty, he served 20 years in prison before being executed with lethal injection.
