Police continued to investigate Sunday after an early morning robbery left the manager of a North Philadelphia Dunkin’ Donuts dead.

Christine Lugo, 40, of Fairhill, was shot once in the head just before 6 a.m. Saturday as she was opening the store, near the corner of 6th Street and Lehigh Avenue, authorities said.

A man with a revolver approached her and forced her inside the building at around 5:30 a.m. Lugo retrieved money from the store’s safe and handed it to the man, who shot her anyway before fleeing the area.

Medics pronounced Lugo dead at the scene.

Investigators released surveillance video of the robbery and described the shooter as a Black man in his late 30s or early 40s with a medium complexion, medium-to-stocky build and a mustache with a goatee.

At the time of the shooting, he was wearing a blue zip-up hooded sweatshirt, gray cargo sweatpants, light gray New Balance sneakers and an analog watch, police said.
