A Philadelphia jury has convicted a confessed cop killer of first-degree murder for fatally shooting a police officer on Halloween 2007.
Twenty-three-year-old John Lewis was found guilty Thursday of first-degree murder in the shooting death of 54-year-old Officer Chuck Cassidy. Lewis shot Cassidy in the head when the officer walked in on a robbery at a North Philadelphia doughnut shop.
Lewis pleaded guilty last week to a general charge of murder and a string of increasingly violent armed robberies. The jury decided between a conviction of first- or second-degree murder.
It will determine, beginning with the sentencing phase Friday, whether he deserves the death penalty.
