Ericka Nicole Harrell, 41, was shot to death in the early morning of November 22, 2011, on the 1800 block of North 22nd Street in North Philadelphia. Police found her at about 1:40 a.m. with multiple gunshot wounds to her face and body and she was pronounced dead at the scene.

Investigators said a heated argument in the neighborhood preceded the shooting, but details about what was said or how the dispute began were not released. The Philadelphia Police Department opened a homicide investigation and appealed for public help; no arrests were reported in the days after the killing and the case later went cold.
