Pa. Man Serving Life Pleads to 4th Killing

EASTON, Pa.  -- An eastern Pennsylvania man already serving a life term on a triple murder conviction has pleaded guilty to a fourth killing.

Twenty-two-year-old Ali Elijah Davis of Freemansburg pleaded guilty Wednesday to third-degree murder in the May 2007 shooting death of 41-year-old Joey Mobley of Brooklyn in Easton. He was scheduled to go to trial Monday in the case and could have faced the death penalty if convicted of first-degree murder.

In January, Davis was sentenced to life without parole after jurors deadlocked over whether he should be put to death. He was convicted in the November 2007 deaths of 19-year-old Aleah Hamlin, 23-year-old Chanel Armour and 21-year-old Alphe Rene, which authorities said stemmed from earlier killings in New Jersey.
