On the morning of April 7, 2018, 29-year-old Abil K. Hasan of Penns Grove was found fatally shot on Railroad Avenue in Millville, between South 4th and South 5th streets. Officers pronounced Hasan dead at the scene at about 1:13 a.m.; the Cumberland County Prosecutor’s Office opened an investigation and asked the public for help identifying the shooter.

The case stayed unsolved for nearly two years, a period that compounded the family’s and community’s grief. About two years after the killing, investigators arrested 27-year-old Allen M. Williams of Bridgeton and charged him with first-degree murder, unlawful possession of a firearm and tampering with physical evidence; later filings also included obstruction and hindering apprehension or prosecution.

What details about that night or the people involved might still help explain how Hasan came to be on Railroad Avenue?
