Overview

  • Amir Jalil Ali, 62, legally changed his name from Kenneth Burnell Wonsom in 2021, was arrested on August 4 in Laurel and remains jailed without bond.
  • Campbell, a 24-year-old Metropolitan Police Department officer, was found shot five times in her Silver Spring apartment on September 16, 1995, and her issued handgun has never been recovered.
  • Montgomery County prosecutors initially charged Ali days after the killing but dropped the case two months later for reasons that remain unexplained.
  • Investigators refuted Ali’s burglary story after finding no forced entry and say forensic evidence indicates he used Campbell’s own service weapon.
  • Colleagues told detectives that Campbell feared Ali, slept with her firearm under her pillow, and had warned she planned to leave him.
