Jeremiah Shaw was 19 when he was fatally shot on August 6, 2014, in the Englewood neighborhood of Chicago.

Witnesses reported a dark-colored vehicle speeding away, but descriptions were not clear and some community members were reluctant to talk, which investigators said hampered progress. The Chicago Police Department canvassed for surveillance footage and interviewed potential witnesses; several leads were developed early on, but no arrests were announced and the case grew cold.

Shaw’s family held vigils and community events to keep attention on the investigation and urged anyone with information to come forward.
