Jennifer “Jamma” Harris, a 39-year-old McDonald's manager and single mother of six who had worked at the company for 15 years, was fatally stabbed on Thursday morning following a workplace argument with a co-worker. The suspect, 26-year-old McDonald's employee Afeni Muhammad, reportedly became agitated after being sent home early and had posted multiple videos online expressing feelings of being disrespected prior to the attack. The stabbing occurred during the dispute, and an armed customer intervened to stop the assault. Muhammad is expected to be arraigned on a first-degree murder charge. Police responded to reports of the stabbing and gunfire at the scene.
