Philadelphia District Attorney Seth Williams has announced that he won’t reseek the death penalty for convicted cop killer Mumia Abu-Jamal, just shy of two months after the U.S. Supreme Court refused to review a ruling that his first jury was given confusing instructions in the sentencing phase of his 1982 trial.

The decision to discontinue pursuit of the death penalty effectively solidifies a life sentence for Abu-Jamal, who was convicted of first-degree murder for the 1981 slaying of Daniel Faulkner, a Philadelphia police officer.
