The brazen murder was captured on surveillance video that is too graphic to show in its entirety, but police are hoping it leads to an arrest.
It happened just after 9:30 p.m. on Franklin Avenue in Crown Heights.
VIDEO | Surveillance footage shows the incident unfold:
Arriving officers found 42-year-old Delia Johnson lying unconscious and unresponsive with gunshot wounds to her head and leg.
She was rushed to Interfaith Hospital, where she was pronounced dead.
The video shows the suspect, described as being in her mid 20s with a heavy build and long blond hair, first exiting a white vehicle.
She then walks up behind Johnson, shoots her in the back of the head, and returns to the car, which flees the scene.
Family members say Johnson was at a funeral earlier in the day and the suspect was also there.
"I asked everybody if they had words, they were both there, but there was no interaction," Mathis Johnson, the victim's brother, said.
Her family believe she was set up because she received a call later that day to head to Franklin Avenue. They said she didn't act like it was anything to worry about.
On Friday night, friends and family vowed to keep Johnson's memory alive at a candlelight vigil.
"She wasn't perfect, but her heart was perfect," Johnson said. "The woman was heartless, she took a sister a daughter away, she took a mother."
No arrests have been made, and the investigation is ongoing.
Anyone with information in regard to the whereabouts of this individual is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
